Arthritic Key Aid

The brief for this project was to design a key aid for arthritic people who might have difficulty with turning a key. The aid would need to be strong enough to withstand the forces of a turning key, and to be large enough to comfortably fit in the user's hand whilst being small enough to fit in the users’ pocket. This project allowed me to advance my skills in ergonomic design.

CAD Work


To test the ergonomics and functionality of the design, a prototype was created out of MDF. This prototype was subsequently used over the period of a week to show any flaws in the design.

The final design for the key aid was produced in the CAD software SolidWorks. This allowed the shape to be easily defined, and whole product to be easily visualised.
