Semester full of Digital Making !

Wow the semester has flew by. I remember taking my disability design course and being heavily encouraged to take this course from my professor Dr Deana McDonagh. I heard countless success stories and instantly got interested. I remember the entire process  of sending a resume and asking access from the instructor. It made the course feel even more official and selective. I wanted to take the course because it could present even more fabrication resources and help me in product development in my startup.

Expectations…

Initially I didn’t necessarily know what to expect. From the course description I thought maybe the the class would be very hands on and explore various methods of fabrication. Even with these little to no expectations the course don’t over promise anything. The course itself wasn’t perfect but it was an overall great experience. It challenged us to think outside the box and look at what we usually consider problems as areas of opportunity for innovation. The structure of the course prompted us to use the parameters set and essentially work through things, which allowed us to learn even more. This style of teaching could go one of two ways. The class could be way to lose, which causes confusion and lack of understanding of expectations. Or it could be how this course went and really give students the opportunity to explore, fail, plan, and execute on an idea.

This course further enhanced some fabrication skills I already have and taught me some fairly new ones as well. As an industrial designer I’m constantly doing project and solving problems. Design thinking, user centered design, empathic design are all things this course subtly hinted in throughout the semester. The workshops enabled us to gain new skills and learn processes. Many of, if not all the guest speakers, provided meaningful insight throughout the semester as well. There are so many takeaways from this class.

Solestice

I was partnered with two bright young women from the college of business. I couldn’t have asked for a better team. We had a great dynamic and right away knew what we wanted to do for the remainder of the semester project.Through the many conducted interviews and mentors stories we gravitated towards Jenna. She shared with us the story of a time where she slipped on ice immediately after exiting her car. This happened all because she can’t wear boots due to the heavy nature of them. This prevents users like Jenna  and other prosthetic users from wearing them as their residual limbs are not strong enough to carry the amount of weight the boot has. This is where Solstice was birthed. We aimed to figure out a way for Jenna to increase traction without adding adding additional weight to her shoes. Our main goal was To create an attachable, lightweight shoe tread that can be used to travel in a variety of terrains.

Low Fidelity Prototype

My group and I brainstormed countless times trying to figure out how to make this idea into a real thing. We’d sketch  ideas and somehow came up with the thought of incorporating spikes ( like in track shoes) it would help with traction. Unfortunately after creating a low fidelity we realized that our user may be required to take said device off when walking indoors. We also wanted to make it as easy to use as possible, while providing a comfortable fit we thought to use velcro. This set us up perfectly to further ideate on this idea and create our very own functioning prototype at the makeathon.

At the Make-a-thon itself team Solstice focused on three main components of creating this product:  Arduino, molding, and attaching. The arduino portion was super cool and challenging. It was my first time coding and working with circuitry. Essentially this would add a unique tech factor to our tread that would allow users to have a sense of force feedback. From research we found prosthetic users have issues shifting weight which can lead to gaits abnormalities. This small pressure sensor would give them that data and in term help prevent this from happening. The design itself was fairly simple. We coded an Arduino Uno to illuminate LED lights that indicated pressure being applied. To create the pressure sensor, we sandwiched a piece of foam with two pieces of copper. Ideally, we wanted for there to be three lights, each indicating where the user is putting pressure on the tread. This would enable the user to ensure they are putting enough weight on their prosthetic to maximize stability.

In terms of creating the tread it we wanted to use a molding compound. This would allow for a lightweight thread, but ensure a grip tread form that resembles that of your regular high traction shoe. We created a mold of a shoe outsole. During this process, we coated the shoe in baby powder and mixed the molding compound to a viscosity similar to pancake mix. We held the shoe down until the mold dried. Following, we used a hot glue gun to fill in the mold with thermoplastic material. After the mold was completely filled, we used a heat gun to smooth the top of the sole, making sure the edges were slightly taller than the inside of the sole. The thermoplastic material we used was similar to silicone and, per our research, is a material that creates enough friction to prevent falling on ice.

For the sake of time and resources we opted to utilize velcro for our attaching method. It wasn’t the worst choice but also wasn’t the best as it came with its own constraints.

Overall I really did enjoy this course. From the challenging nature of it to its looseness it was a great experience. I got to learn new and exciting skills. I got to meet some amazing people. Most of all I got to make something with newly found campus wide resources. I’ve really grown as a individual because of this course. I find myself a better teammate. The collaborative portion of this course really ties teams together and promotes all hands. Hopefully you’ll see a team Solstice sole on the market. We really did nurture this product and can’t wait to see it reach its full potential. Never stop making!

A Designed Journey

EXPECTATIONS.

In terms of expectations for the course, I thought that there would be a lot more tool training and 3D printing involved. Instead, our time was split evenly between team prototyping and tool training. While I knew about the prototyping project, it was both less structured than I expected and more involved than I thought it was going to be. On one hand, we were given the guiding information and assignments to go about prototyping our ideas, but on the other hand, a lot of the initiative was left to our own self to start conducting outside research and interviews, start tool practice and learning, and start networking and testing our prototype.  I had honestly expected the course to “hold our hands” a little bit more than they did, but I am very glad that it did not. In the end, I was able to learn more about the way that I tackle large projects without much guidance as well as learn more about design thinking and the prototyping process. Before, startups were a bit of a mystery to me, a buzzword many people use in business talks, but going through the prototyping process helped me truly understand what a startup does and how difficult that process is.

Another aspect I had not expected was how closely we worked with DRES. I had expected a course about digital making, especially a course housed within the Gies College of Business, to be more bottom line focused in their innovation themes, but the accessibility work and disabilities focus we had in class was a nice surprise. Having done some disabilities advocacy – albeit more on the mental health side rather than the physical disabilities side – before, being able to work in this field put me a little more at ease. It was incredible to see the real impact that our prototypes had on real people at the end of the course.

Group Interview at DRES with our mentors

To see a more in-depth break-down of what the first few weeks of class were like, read the following blog posts:

COMMUNITY + OPEN SOURCE RESOURCES.

It was really cool to be able to learn how to use a multitude of new programs within this class; the program I was most excited about learning was Autodesk’s Fusion 360. My brother took a 3D printing class our senior year of high school, and I was always fascinated by the projects he brought home to show our family. As a result, I was both anxiously anticipating and incredibly excited to work with 3D modelling for the first time during this seminar. Upon completing Lars Christensen’s Fusion 360 tutorial that we used to familiarize ourselves with the Fusion 360 program, I felt really accomplished and inspired to explore 3D modelling further.

It was around the completion of our introduction to Fusion 360 that we were introduced to a community resource on campus: the Champaign-Urbana Community Fab Lab. For such a compact space, the amount of resources available there was incredible! I was so surprised that we had so many resources available to us as members of the Champaign-Urbana community, and yet, not many people knew of these resources. One of my goals after this class is definitely to let more people know about the plethora of resources we have available to us here in CU. During our three weeks at the CU Fab Lab, we completed a culmination project which taught us how to use Inkscape, an open source vector program similar to Adobe Photoshop or Illustrator, to create laser engraving files; create code and build Arduino programs and other electrical configurations; and use a sewing machine on various types of textiles. Overall, it was a really cool experience that allowed me to familiarize myself with new tools and gain new ideas on what types of innovation could be used to help me create my prototype.

For more detail on what the tool training experience was like for me, feel free to reference the following blog posts:

PROTOTYPING.

As part of the prototyping process, we went through many different concepts related to design thinking. First, we learned about human centered design and empathetic design, which really appealed to me. Before, I thought that innovation and prototyping design was only for the random moments of inspiration where someone looks at a problem and is struck by the inspiration to find a solution to it in order to make money. However, we were taught that wording is another important aspect of designing and that we should think of our prototypes not as “solutions to problems” but “ideas for to fill an opportunity,” something that we can use to help people with. We also learned about diverging during the brainstorming process and then converging back upon a decided path to take a prototype idea. Through this process, I was confronted with my indecisive nature. Although I had subconsciously known this, I had not realized why I was so indecisive. Yet, during the prototyping process, I realized that I was indecisive because I feared the failure of arriving at the wrong answer. I disliked choosing a path, preferring inaction over actively choosing wrong. Taking this course has really helped me realize that about myself, and I now try to challenge myself in my daily living to make quicker decisions, to choose a path rather than being crippled into inaction. I am learning to trust my instincts and gut feelings a little more than I did before.

One example of this was the iterations that lead to the drastic changed between our (Team Solestice’s) low fidelity prototype, our Make-a-thon prototype, and our post-testing prototype. In the first prototype, we were thinking of using metal spikes as a source of traction, and we committed to the idea. However, upon further research, before we even got to the Make-a-thon event, we realized that it was not feasible, that it would be even more of a problem for a user to have to take the tread off and put it back on every time they switched between walking outdoors to indoors and vice versa. And here we thought we had the correct idea. Yet, after we tested our prototype with a prosthetic leg user, post-Make-a-thon, we realized once again an opportunity for change. We realized that the tread was too heavy and the Velcro too visible. So, we switched gears once again to look at being able to apply the tread directly to a shoe. So, it was through this course, our prototyping project specifically, that I understood an opportunity for myself to learn to face failure head on, to learn to be okay with the fear of failure, and to keep working, regardless.

For more details about the preparation I undertook with my team for the Make-a-thon event, take a look at the following blog posts:

This course has taught me so much, not only about the different innovation tools available in the market right now, but also about myself. I have grown not just in marketable skills, but also as a person, and for that, I am incredibly thankful that I took a chance, braced myself for failure, and applied to be a part of this course.

Post-Make-A-Thon Recovery

From Friday, April 12th, 5:00 pm to Sunday, April 14th, 2:00 pm, we participated in a Make-a-thon. Yes, it was a LONG weekend, but I had a lot of fun, not just developing the idea with my team, but also seeing the brilliant ideas that other teams came up with. It felt amazing to be finally turning our ideas into something tangible and demonstrating it to others.

Before heading into the event, my team and I were still exploring a couple of different ideas for the protective cover of a power wheelchair joystick and decided that we would try to develop a prototype for both. One of the ideas was an armadillo-style cover that would function like the cover that is found on baby strollers.

Baby stroller, which inspired us to come up with an armadillo-style cover for a power chair.

On Friday evening, we met with Ryan, our expert user, and shared this idea. He seemed to be interested in the idea but shared a few of his concerns about it, including the visibility of the screen, buttons, and joysticks that would be protected by the cover. After the meeting, my team and I discussed the idea further, wondering whether it would be best if we continue to focus on trying both ideas or dropping this one. While discussing it, we also realized that this armadillo-style may not be as effective if it is used in a windy condition as the rain could still easily get to the electronic parts of the chair. Therefore, although we really liked this idea since it was unique, we decided to focus our efforts on creating a prototype for the other idea throughout the event.

After this decision was made, one of my teammates and I decided to scavenge for materials around the Fablab. Since we decided on the skin idea, similar to that of the phone covers, we were looking for a transparent material that could be wrapped around the arm of a power chair. We were very lucky to find one that perfectly suited for this purpose.

A flexible phone cover that is transparent, which inspired us to come up with a “skin” for the arm of a power chair.

The following day, a fellow student from the Fablab course joined our team to work on the project together for the duration of the event. After we caught him up on our ideas and the progress, we were able to work together extremely well, making progress quickly. From gathering the rest of the materials to designing the prototype, everything progressed smoothly. Using the dimensions of Ryan’s power chair that we measured earlier, we made a copy of the arm using styrofoam. Based on this model, we were able to wrap the transparent material around it to mold and cut it into the shape that we needed it to be.

In addition to the cover, we wanted to provide texture on the part that covers the joystick to allow for a firmer grip for the users. Not only would it allow for easier use for the user, but it would also provide a more secure feeling, which we decided was important to offer with our product. We were able to mold a material around the joystick with grooves of a grip to demonstrate this.

While we were working on this, one of the teammates worked on using Arduino to create a testing device that could detect whether moisture was entering through the cover or not. He was able to code and successfully build a device that would make a beeping noise when it detected moisture. Although we do not think this would be a part of the final product, it is something that we plan on using to test our prototypes in the future to check for its functionality.

Initially, although I was happy that we were able to create a prototype and demonstrate our idea to others, I was not as confident in it. I thought that it did not have enough differentiating factors that made it unique. Fortunately, others did not think that way. From judges to supports, everyone showed their interest in our idea and provided their own inputs for it. Everyone was so supportive that I felt proud to showcase it. I learned the importance of not doubting myself and instead, being proud of the work that my team and I have put in throughout the event. From working in a team environment, providing and receiving feedback, to learning to use different tools, this experience taught me a lot of valuable skills that I will continue to use.

For the rest of the semester, we are hoping to move on from this transparent plastic material that we found and work with silicone instead to create the cover. Now that we have the idea set on how it will look like and how it will be used, we want to create it with the actual material that we are hoping the product to be made with. With silicone, there may be additional adjustments that need to be made on our design, which is why we believe it is critical to create a prototype with it. We are very excited to see how far we can get with the rest of the semester.

Prototype Development

As the date of the Make-a-thon approaches, my team and I are trying to narrow down on our options for the prototype. With selecting one or two prototypes to continue as our objective of the week, we shared our ideas to Milestone Labs to receive their feedback. From the bridge-style and an armadillo-style to a molding idea, we had a wide range of ideas for the cover of the joystick for a power wheelchair. Although we liked the idea of providing a molding kit to the user so that the cover can be customized for the specific wheelchair along with the possibility of adding grooves for the grips or using different colors, we realized that this method is most likely out of our reach to achieve for the make-a-thon event. Therefore, we decided to continue with the prototypes that we can make further progress with.

During the discussion with Milestone Labs, we shared our findings on the market research and how the current joystick protectors on the market are ugly as seen below.

However, when we came up with other ideas with better designs, we discovered the challenge of making the product fit with different types of chairs in order to increase the user base. When we shared this problem with Milestone Labs, they told us to focus on our direct user, Ryan, first and see how it goes from there on.

After consulting with Milestone Labs, we came together as a team to have a discussion about our prototypes. Our original prototypes were made to protect the joystick itself, but after reviewing Ryan’s power chair, we decided that it would be important to also protect the screen and the buttons on the arm of the chair. Therefore, we developed an idea of a protective sleeve that would fit around the arm of the power chair tightly for the improved appearance compared to the ones in the market. The design is shown in the sketch below.

After the sketch, we discussed the potential materials that can be used for the product. There were many things we needed to consider, including:

  1. Is the material waterproof? Will it be able to withstand a lot of rain?
  2. Can it withstand a variety of weather conditions including but not limited to rain, snow, cold, humid, hot, and direct sunlight?
  3. Is it transparent so that the user can see the buttons and the screen through the cover?
  4. Is the material affordable?
  5. Is the material durable yet flexible enough that it can be molded around the joystick as well as the arm of the power chair?

Considering such questions, we developed a list of materials, which can be seen in the picture above on the top right corner of the whiteboard. We also discussed the mechanism for wrapping the sleeve around the arm of the chair, including buttons, zippers, and velcro. We talked about whether one method was easier to perform than the other as well as the effectiveness of it as both factors are crucial for the users.

Although we had many ideas before, we were unsure which route to take for the project. This week, we were able to narrow it down and come up with solid details for the product, so I am very happy with the progress that has been made. We are excited to get our hands on the materials and start working on the prototype. In the meantime, we are planning on meeting with Ryan again to measure dimensions of his chair as well as developing low-fidelity prototypes using papers and fabrics.

FabLab 2.0

Inkscape vector file of watch to be laser cut

This week we returned to the FabLab. We continued to familiarize ourselves with all the tools and tech the lab has to offer. We specifically learned a vector editing software called Inkscape. Through this workshop we learned how to create basic shapes, manipulate them, and produce more. After learning the basics of the software we learned to transform images into vector graphics. These skills were then applied to a customized watch. The watch is a device that allows patients who have to do bicep curls and rotation in wrist during rehabilitation. The base of the watch consist of 3 wooden circles, two of which have rectangles on each side. I thought it would be help patients if the watch had small arrow indications of which way the device goes. The top layer rotates, so I designed an arrow pointing in the direction of proper rotation.

3 layered watch with electrical components

After this we moved into sewing. Unlike most of my peers I have experienced sewing. My sophomore year I sewed a jacket with a sleeping bag attachment completely from scratch. So during the tutorials and walkthroughs I was a couple steps ahead. We all picked the fabrics we wanted our wristband for the watch to be and then cut it to scale.  We sew it right sice in and sewed the seam. This created the sort of sack like appearance of the band. Getting it right side out was a hassle, it required us to use these thin wooden rods to pull the fabric through. We finished up by attaching velcro strips to the band to ensure a comfortable and secure fit to the wrist.

Images showcasing the process of sewing and creating the band for the watch

The second half of class each group presented to Milestone Labs and Adam Bleakney. We’ve made a lot of progress since last speaking with them. We got a lot of insight from this conversation. We realized we hadn’t thought everything thoroughly. Our design is solid but we have to really hone in on the attachment aspect of it. The overall ease of use should be convenient for the user. They also asked a lot of questions regarding materials of our device. We are currently scheduling a time to interview a material science professor here at the university. This week I have scheduled a virtual interview with my physical therapy. We also have a meeting this monday with my professor who handmakes shoes. We plan to do a bunch more research structured around our opportunity and project idea.

Return to the Fab Lab: Week 8

Our time at the FabLab has been focused on making a cheap, interactive watch face that helps doctors measure whether outpatients have been completing their proper outpatient physical therapy sessions. Last week, I learned how to build the electronic circuit in the watch face. This week, it was our class section’s turn to learn how to laser print the watch face and sew the watch strap. After learning these tools, we met with Milestone Labs to receive feedback on our prototypes and then worked with Jenna to begin to design the second iteration of our prototypes.

Learning InkScape

Our first lesson was on the laser printing and etching software InkScape. We learned that InkScape has many different capabilities and we were able to play around with designing shapes and importing silhouettes from the internet. After we gained som familiarity with the tool, we were tasked with desiging an easy to use watch interface that would help user differentiate between the settings for both the “curl” and “twist” exercises. For my design, I decided to orient different arrows to show which way the watch face should be facing to correctly monitor each different exercize.

Sewing Refresher

The next portion of our class was focused on learning how to sew. When I was little my grandmother had taught me how to sew, but that was such a long time ago that I needed a refresher on how to work the machine. However, after a short tutorial, I was able to get up to speed and feel confident in my sewing abilities. One of my biggest takeaways was the improtance of backstitching. Backstitching is when you stitch backwards at the start of your stitch to reinforce the line so it doesn’t unravel overtime. At first, I made this mistake and needed to go back over my original stitch. Once we felt comfortable sewing we were given the assignment to make a watch strap. The watch strap had many steps, but are instructor Duncan did a great job leading our class through them and we all came out with acceptable watch straps by the end of class.

  • Fab Lab Sewing Machine

Milestone Midpoint

In our next portion of the class, my team met with representatives from Milestone Labs to discuss our progress so far. The designers at Milestone Labs were happy with our current progress but challenged us to get more user interviews from a wider variety of sources. They recommended interviewing veterans and elderly users and we have worked on contacting different users from these designations this week. They were also impressed with the prototypes we had made and gave a few suggestions, such as th BOA strap, on ways to improve our designs.

Testing and Iterating

Our next step was to meet with our mentor Jenna to test out the prototypes we had created on her prosthetic leg. After testing our prototypes, Jenna told us that while she liked the basic concept of our sleeve design, it would not work because the fabric might interfere with the walking mechanism at the back of her knee. This was an important discovery because it meant that we had to alter all of our prototypes to stay away from the back of the knee. To me, this was a big learning moment that reinforced the importance of prototype iterations and user-centered design. While our original prototype was good in theory it would have failed to meet Jenna’s specifications because we had overlooked an important aspect of its usability. After our talk with Jenna, our team brainstormed and came up with a new prototype idea that hooked on to the top of the knee and the back of her calf. We will work on prototyping this new design and get ready to show it to Jenna again this week!

FAB LAB!!!!

This week I wasn’t able to physically be in class due to some unfortunate circumstances. I was however able to visit Jeff and see the Fab Lab prior to this weeks workshops. I learned of some of the complex filments and advanced 3D printers. I got to know a bit of the staff as well. In terms of class, I was able to get up to speed from my wonderful team members. This week was the start of our workshops through the Fab Lab. The class was given a tour of the entire facility by Jeff Ginger, who is the director of the lab. He gave a presentation during last weeks class. After the initial tour the class was split into different workshops within the fablab. Some people were learning the laser cutter while others built circuits.

After this the class went back into their  groups and brainstormed for the remainder of the class period. The TA also assisted during the brainstorming session given a different prompt every 3 minutes. This helped further our ideation and conceptual prototyping, while designing with an open mind. My group was able to rapidly draw up multiple porttype ideas with the given parameters of the prompts. In case you forgot,  we are developing a shoe tread to facilitate walking on ice/snow (all terrain) for prosthetic users. By the end of this activity my team was able to come up with a MVP. They chose the easiest and most feasible of the concepts that we can make a crude prototype of. By next class we will have a usable prototype of our tread attachment. It will have velcro straps to connect with the shoe and acchatable spikes on the tread.

Creation Station: Week 7

This week was jam-packed as our team visited the Fab Lab, brainstormed potential prototypes, 3D printed our fusion models, met with Jeannette Elliot, and created our first low-fidelity prototypes.

Introduction to the Fab Lab

Our class this week took place in the Fab Lab on campus. The Fab Lab is a maker space that houses designers, makers, and innovators from the campus and the local community. I was blown away by the amount of creativity on display at the Fab Lab. People had let their imagination run wild and were creating anything that came into their head. One of my favorite inventions, was a keyboard made out of wood and copper tape. I was struck by the simplicity and cost-efficiency of the product when compared to typical keyboards. In the Fab Lab, we were split into two groups to learn a little bit more about the various resources. My group worked with arduinos to create a circuit that could turn a lightbulb on and off based on its horizontal or vertical orientation.

  • Example of items lying around the Fab Lab
  • Exterior view of keyboard
  • Interior view of keyboard
  • Inside wall in the Fab Lab

Diverging on Ideas

During the second half of class we split up into our teams to brainstorm potential solutions for the needs we had identified. We were given 4 different prompts to challenge us to think creatively about the problem. At first, I was worried that our group would run out of ideas after the first prompt because I thought there were only a few ways to solve our problem. However, being forced to think about designing our problem for little kids and the elderly forced us to think outside the box and explore new possibilities.

Our design ideas from the brainstorming activity

If at First You Don’t Succeed, Try, Try Again

After class, I went to the Makerlab to pick up the 3D print of the phone holder I had designed on Fusion 360 during the last class. However, when I got there I was dismayed to see there had been a failure and the top of my phone holder had failed to print. When I talked to the lab assistant about what happened they told me that sometimes prints fail and that I should just try again. Luckily, my phone holder and the box and lid I created were a success the second time through. This taught me a valuable lesson that while 3D printing is very cool it is still an emerging technology and it is not perfect all the time.

  • Failed phone holder print
  • Successful phone holder print
  • Box and lid print

Stakeholder Meeting

Later in the week, my team had a chance to meet with Jeannette Elliot. Jeannette is a physical therapist at DRES and a prosthetic leg user. Our interview with her was very informative and we learned about the struggles she has had in the past with prosthetic leg protective covers. The main takeaways from our conversation were the importance of maintaining flexibility with the cover, keeping the cost affordable, and offering customization options to appeal to the different aesthetic preferences of users. Our team is very thankful that Jeannette took the time to share her insights with us!

Design Time

The week ended with our team making our first low-fidelity prototypes. The 3 designs we chose to prototype were a knee pad attached by velcro, a flexible knee pad attached by a hook and ring strap, and a fabric sleeve with a knee pad encased inside. Our next steps will be to show these designs to Jenna and get her initial feedback.

  • Hook/Ring Strap Prototype
  • Fabric Sleeve Prototype

Fab Lab: Fabulous Resources for Fabulous Ideas

Exterior of Fab Lab located in Urbana, IL

This was our first of the next three weeks that we will be spending at Fab Lab to learn about various resources that are available to us. Although I have heard of Fab Lab before, I was not aware of what it contains. In fact, I didn’t even know where it was located, so I was very surprised when I found out where it was. It was a small, old-looking building that I passed by daily to get to my classes from the dorm that I used to live in during my freshman year. I always wondered what it was and even peered into it through the windows once, but I never figured out what it was. Walking into it, I was wondering how this place could contain all the high-tech gadgets that the professor was talking about.

As soon as I walked through the doors, I had my eyebrows raised. It was not at all what I imagined the place to be.

  • One side of the wall at Fab Lab displaying different products that are made there
  • Example of a machine that is available at Fab Lab for use
Examples of various products that can be made at Fab Lab

Inside the building was an open space filled with computers, machines, and various types of products that were made at the lab. I felt like a kid who just walked into a candy store, trying to absorb all the different things that I see. From electric cutters, 3D printers, to embroidery machines, there seemed to be endless lines of resources available. Although I was excited to see so many resources, I was also worried about how I could possibly learn to use them for the project.

  • Examples of laser engraved products from Fab Lab
  • 3D printers available at Fab Lab
  • Map of the Fab Lab

After taking a tour throughout the building, the class was divided into two groups to get hands-on learning on a couple of resources available at the lab. This week, I got to participate in an Inkscape workshop. Inkscape is an open-source vector graphics editor, which can be used to create or edit vector graphics. During the workshop, we got to design a watch face of a motion-detecting watch, which could detect whether the user was performing the bicep curls or wrist twist motions correctly. We were to think of a specific user group and create a design based on it so that the user can use the watch correctly. Although the task seemed simple, it was challenging to come up with a simple, yet effective design. This exercise made me realize how much of a challenge we have ahead of us in trying to design a product that could help the power wheelchair users with preventing the rain from getting into the joystick.

After the workshop, we were grouped into our own teams and got time to brainstorm various prototypes for the team products. The point of this session was to keep the options limitless, even thinking of things that are impossible for us to achieve. For example, while we were brainstorming about what can protect the power wheelchair from rain, we came up with instant heating that dries the moisture, force field, and strong wind blower that can push the water droplets away. Although we understand that these options are not viable, by not limiting ourselves, we were able to come up with more creative ideas that can potentially lead into more feasible ones.

Sketches of various ideas we brainstormed during the session to prevent rain from getting to the joystick of a power wheelchair

In the end, we had to select a couple of designs that were more feasible, easier to implement, and most effective, which we decided were bags to put over the joystick and a mold that can be put over the part. For our next assignment, we will be coming up with a 3D prototype of these ideas. Although the exercises that we performed throughout the week demonstrated lots of challenge ahead of us, I am excited to use the available resources to take our ideas further.

New Resources: A Fabulous Lab

FAB-TASTIC.

This week, we got a formal introduction to the Fab Lab. The director of the Fab Lab had previously been a guest speaker in the class, but this time we had a chance to host the class there and use their facilities. We first started with a tour of the place and the different tools they had there. They first went through their policies for use, which was surprisingly accessible. Most tools were only priced at $1 for use, and they allowed people to use their own materials while also having some for sale.

In terms of the tools, the staff went through the multiple applications of the electric cutter, which could not only be used to cut vinyl stickers, but also precision paint things if the knife part was replaced. Next, they showed us the screen printing and embroidering/sewing areas. They also introduced us to the concept of 3D printing on top of meshed fabric, which has been used a lot in the fashion industry recently (seen green scales picture for an example). Next, they showed us the milling, soldering, and electronics area, where they showed some applications, such as milling your own circuit board or working with microcontrollers. Finally, they brought us to the 3D printing and laser engraving workstations. Overall, it was really inspiring to see all these different technologies consolidated in a single area as well as to hear about many of the different projects that have been created at the lab. I was shocked to find out about such an untapped resource that I had not known that I could take advantage of as a resident of the Champaign-Urbana area.

FABRICATION IN PROGRESS.

After our brief but thorough tour, we were split into two groups to attend workshops run by the staff of the Fab Lab. I attended the workshop relating to using the laser engraver as well as the program used to vector model what we want to engrave, Inkscape. Inkscape is an open source program which is quite similar to Adobe Illustrator and allows people to vector model their illustrations; I found it really fascinating that the Fab Lab intentionally uses a lot of open source software so that when they teach people how to use their programs, the skills will continue to be applicable outside of the Fab Lab.

Within Inkscape, we started modelling an exercise watch made out of wood which would be able to track if outpatients are performing their exercises correctly. There will be motion sensors inside the watch, where if the face is facing one way, it would detect bicep curls and facing another way, wrist twists. We first modelled the watch face together while the instructors introduced us to the program, and once we started to become more familiar with Inkscape, the staff released us to add our own designs to the watch. We were instructed to keep the user base in mind and make our unique designs while thinking of certain groups, such as children or elderly outpatients.

With the last 45 minutes of class, we started brainstorming prototypes for our team products. While brainstorming, our TA Mehmet wanted us to think of new ideas quickly, never spending too much time on a single idea. We were instructed to brainstorm in different rounds with different restrictions. For example, one round we had to think as if we had a $0 budget, another if we had an unlimited budget, and yet another if we had to think of our product with children in mind. In the end, we then had to decide which prototype we thought would be the most feasible, easiest to implement, and most effective and decide based on individual team members’ decisions which prototype to make a crude 3D prototype of. In the end, Solestice decided to go with a sole that is attachable by Velcro strips to a shoe, and we will be making this prototype before the next class.
