Here are some highlights thus far...
Adaptive Device - Karuna's Trumpet Holder
I've fully designed the attachment mechanism for an adaptive device that will eventually have a palm and gauntlet for a child who plays trumpet. What is exciting about these parts is that the mechanism for attaching a hand and gauntlet is so simple that it could potentially be integrated into many different types of adaptive devices.

The palm and gauntlet have not been developed quite as far as the rest of the design; they are still in need of lots of refinement. These parts are challenging me in a new way. Where the trumpet adapter was fitting on consistent, geometric shapes that lent themselves to be built with solids - Karuna's palm and gauntlet are exactly the opposite, demanding organic undulating curves that are in need of dynamic curve networks in order to fit his body's contour.
I designed a palm and gauntlet (v1) that attached to a dovetail with a Chicago screw, but decided to re-design them both to be more form fitting... I am in the process of re-designing these parts this week. See how far I've gotten.
Once the final designs for Karuna's hand and gauntlet have been finished, I will be starting on the second set of milestones that I've set for the Fellowship; material and process experimentation for the creation of hands.
"Weeks 4-9: Research, design and prototype with alternative materials and processes for the creation of hands. Materials of interest include; (1) exos shaping technology, (2) silicone rubber molds and (3) cast-able flexible materials. Processes and outcomes of interest include; (1) laser cutting for fabrication and flat-pack design, (2) creating standardized molds for alternative production of 3D printed parts and (3) casting flexible materials to increase potential range of motion, aid in comfort and integration on the wearer. Throughout these tests, design aesthetic and function will be prioritized to facilitate innovation." - Written Plan by Caitlin Driver
Last week, Frankie and Adream had a representative for DJO Global visit the DCRL. They brought with them various products that utilize exos shaping technology. The flexible sheet material used in their products was fun to play around with; it required a brief heating and then was fully mold-able to any desired area on the body. Frankie is investing in some of the material, so I can begin to experiment with it individually and with 3D printed components. I really hope that through the material explorations I can find a new way to design hands effectively without spending the amount of time it currently takes to create hands with 3D printing. I will be posting daily during the week on my blog about my progress.
