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!


All Final Checks Completed & Anticipation

PREPARATIONS & LOOKING AHEAD

We started this week’s class with Vishal reviewing the Make-a-thon schedule in case any of us were confused or missed the Pre-Night Event. Following that, he introduced us to Valeri, a representative from Social Innovation @ Illinois. Social Innovation @ Illinois is one of our Make-a-thon’s Gold Sponsors and is funding the appearance of our mentors from Milestone Labs during the weekend of the Make-a-thon event.

Valerie also spoke to us about an opportunity to continue our innovative ventures during school while gaining funding and several experts as resources: the iVenture Accelerator. iVenture is a start up incubator that takes the form of a 10 week internship over the summer and a seminar class for a full academic year that allows participants to further develop their startup. The Accelerator provides $10,000 of funding to the startups chosen as well as stipends for its members to stay on campus over the summer. Throughout the internship and the class portion of iVenture, supplies its entrepreneurs with funding, experts, networking opportunities, and more. My teammate, Trevor Sibby, actually went through the iVenture Accelerator with his startup, Nouvo, which I mentioned last week.

THE LAST CHECKPOINT

Once Valerie finished up her presentation, we had time to work in our teams while we, team by team, met with Milestone Labs for a final project update review and advice session. My team, Solestice, went first. During our review with Milestone, we talked through our new thinking for our prototype. While before, we were thinking of using metal spikes for the tread, we have since then moved onto the idea of using a type of material similar to what is used on winter car tires, which have incredible traction for driving on ice and snow, as the main component to our product. While we have also considered a couple other materials, such as a shape memory alloy, we will be meeting with a materials science professor soon to confirm which option would be the best to use for the Make-a-thon event. We had also considered a couple of other attachment methods aside from Velcro, such as snap buttons. Oded from Milestone actually shared a YouTube video with us which has given us another method to consider – one where the user can simply step into the tread. Milestone also pointed us in the direction of considering the whole experience of using the tread, including what happens if the user falls down, whether or not the user has to take the tread on/off when travelling outdoors/indoors, as well as a keeping in mind the wear and tear of shoes. Overall, it was a very productive and positive meeting.

Once we finished up talking to Milestone, Solestice moved onto brainstorming the types of materials we would need at the Makeathon in order to complete our prototypes. We found out that winter tires are made of a material called hydrophilic rubber, so we tried looking around for something similar. However, since none of us are science majors, we struggled a little with reading all the scientific chemical names thrown at us in our search. In the end, we decided to go with trying to use a bicycle tire as a similar material to the winter tire and explaining to the Make-a-thon judges what our ideal product would include. Next, we looked for sites where we can obtain Velcro, straps, and other methods of attaching the tread with the goal of testing these different methods during the Make-a-thon to see which is the easiest for the user to use.

We are all super excited and cannot wait for the Make-a-thon event we will be attending next weekend!
