24-370 Mechanical Design: Methods and Applications · Fall 2024 · Team of 6
Overview
In this mechanical design class at CMU, my team and I built a rotating hand-mixer stand for users with arm or hand muscle weakness. It’s basically a low-cost, accessible alternative to a stand mixer using simple mechanics and PLA parts.
My teammates handled most of the CAD, electronics, and heavy calculations, while I focused on visualization, communication, and analysis. I helped with the FEA setup, created the CAD renders and motion animations, and took all the product-style photos of our final prototypes. I also contributed to early ideation, the budget, and the continuous-improvement analysis, and I even filed an IP disclosure with CMU’s CTTEC just to see if the idea had potential!
Overall, it was a fun team project that taught me a lot about collaboration and user-focused design, and it was super rewarding to see everything come together in the end.
