The week started off with the 4th of July fun. We went went to Hermann park on monday night to watch fireworks show. It was very exciting to have a feel of the American independence day celebration. On Tuesday we got back to work and we stared with scoring ideas the ideas we brainstormed on elbow attachments. It coincidentally happen that our winning design solution was structurally similar to wrist attachment’s winning solution. It was the clamp mechanism with two pieces with squishy padding screwed together . We decided to prototype the two design blocks simultaneously and it worked perfectly
We iterated our prototypes through squishy padding materials, clamp structures and locking mechanism. For our initial prototypes we built 3D printed clamps with foam padding and locked by screwing nuts and bolts. This was tested to be a little uncomfortable and pretty annoying to screw the clamps. On our next iteration we padded the clamps with silicone mold and locked the clamp by latching the two pieces with Velcro straps. We also made structural alterations as we introduced fillets on all sharp edges
The two attachments were roughly integrated to the measuring ring to test if the assembled device will function properly. It worked well but we hard some few problems such binding which we are currently working on. We also made a few structural alterations to the ring model with feedback we got through the rough integration. We designed tabs sticking out of the ring to provide means for attaching the elbow attachment and a concentric ring sliding on top of the main ring for gluing our measuring scale
On Wednesday we had a needs finding workshop where we learnt techniques of generating needs from the community around us. We mimicked some disabilities such as visual impairment, arthrogryposis and mobility impairment to have a feel of the needs of people with disabilities. on Thursday we worked on painting a tree house. This was an exciting experience because we had a chance to apply the knowledge we learnt in the post-processing workshop.
