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!

Culmination at the FabLab

A bittersweet moment occurred this week when we realized we will not be in the FabLab space again. These 3 weeks were filled with exploration, innovation and assimilation into a working space that mimics an adult playground. The hours flew by in the FabLab as we finally wrapped up our projects and finalized our watches, utilizing laser cutters, Arduinos and more in the meantime. It was an extremely insightful experience which reminded all of us business majors at how technically incompetent we truly are.

 Later, we broke up into our teams and began storyboarding our user experience. We walked through each necessary step that our target user would have to go through in order to utilize our product correctly. A user manual will most likely need to be provided since any mechanism which protects the power chair joystick will need set up and an attachment.

We’re on spring break right now and are at the stage of conducting market research to find a product-market fit and exploit it once we get back. April is going to be extremely busy as we have a make-a-thon in the 2nd week which is supposed to expedite this product development cycle.

I’d be lying if I said overwhelm wasn’t starting to creep in. As a second semester senior I am slated with 3 group projects, and a venture which I am taking through COZAD so it is especially difficult to dedicate the necessary time to excel. All 4 projects require damn near full-time attention which makes it unfeasible and very difficult to cater to each of the requirements. Something I’ve already realized is that the business curriculum needs to push more of these group projects to freshman and sophomores before the older class begins to start developing a stronger sense of autonomy.

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.

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.

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.

A Fusion of Knowledge

THE VIEW FROM THE STUDENT’S DESK.

This week, we dived into using a CAD program called Fusion 360. First, as part of preparation for class, we read through some of the program’s guides and watched a video that walked us through creating a lidded box. In the process, we had our first introduction to Fusion360’s interface and built upon our 3D modelling experience from using Tinkercad as we had before to being able to use Fusion360 as well. In terms of complexity, Fusion360 definitely seems like a more complex program that we can use to create a wider range of models more efficiently than Tinkercad, and I was incredibly excited to be moving along in the 3D modeling learning process.

  • Original Model Created
  • Materials Application
  • Mesh for 3D Printing

For class this week, we got to attend a workshop by a representative from Autodesk. During the workshop, we were taught more about Fusion360 and learned more quickly and thoroughly through the guidance of the representative than we would have if we had set about messing around by ourselves. Throughout the process, we created a phone holder as a project which would allow us to explore many of Fusion360’s features. The versatility of Fusion360 was really fascinating to me. Although this is a relatively small feature which may not impact the modelling process as much as other sketching and creation tools, I found it interesting that we could change the different materials that we were modelling as well as model painting and enameling the model at the end. There were so many different combinations possible, and it is even capable of rendering a 3D model within a couple set backgrounds and lighting settings to simulate possible real-life locations. Additionally, the Fusion360’s feature that allows you to go back to each individual action and edit it without destroying any processes you have applied to it afterwards is going to be incredibly helpful in future projects. Afterwards, we were able convert the model to an STL file and 3D print our first model ever. I really felt a sense of accomplishment in being able to hold something that I created and modelled from scratch myself.

DEVELOPMENTS IN PROGRESS.

During the last hour of class, we were able to touch based with our TA and mentor, Mehmet, and he helped guide us through developing further along our project ideation process. We first quickly reviewed the concepts we had gone over in the previous week before moving onto creating insight statements based on the themes we had created. These insight statements describe challenges for the people in the community that we interviewed based upon each of the themes. For example, one insight statement Solestice came up with was “Stigma of looking different affects the [prosthetic] user’s self-confidence.” After gathering our thoughts with these insight statements, Mehmet introduced us to the idea of “How Might We…?” Questions. These questions are meant to be created neither generically nor too specifically and can be used as ways to think of our project goals without getting tunnel-vision with a single solution idea. One of the questions Solestice came up with was “How might we increase stability for prosthetic users?”

Our only other update on the project is that we are in the process of scheduling an interview with a professor who makes shoes in his free time to learn more about a shoe’s design functions and how we might use those design aspects to our advantage with the tread we end up creating.
