This CAD project involved the structural redesign of a prosthetic arm shell to address failure points identified in a previous iteration. The original design exhibited structural weaknesses around the hexagonal lightening cuts and the front grip mounting area, which resulted in failure during testing. To resolve these issues, material thickness was increased around the cutouts to improve rigidity. Additionally, the front grip mounting interface was reinforced by doubling the number of attachment points, distributing loads more effectively and enhancing overall durability.
The completed arm shell revision assembled.
Original arm shell, note the single mounting interface on the front grip, using only two screws.
Shell component with the new front grip in place.
Improved armshell, with significantly thicker cross sections, and four screw mounting points within two mounting interfaces for the front grip.
FDM printed shell component with the new mounting interface.
New top shell cover with thickened sections between hexagonal cutouts to improve structural rigidity and durability.
