Arthri-Grip

The bilateral jaws needed redesigning to improve grip on certain items such as carrier bags and large plastic bottles. These jaws are used for both litter clearance and as domestic living aids so consideration for both applications was crucial.

I made the jaws slightly shorter to give better mechanical advantage but without affecting the opening range. I changed the internal surfaces from a flared-outwards design to parallel sides, so that the gripping force always acted inwards instead of squeezing the object out. Finally I added interlocking serrations to the tips in order to create a better mechanical grip on flexible items such as plastic bags a fabric.

The handle and cuff support needed to be reverse-engineered so that new tooling could be made. This involved precise measurement and complex surfacing to accurately recreate its ergonomic curvature.
