Mobilitray
My second year engineering design project focused on developing an assistive device for individuals using posterior walkers.
Mobilitray
Mobilitray is an assistive tray system designed for individuals who use posterior walkers. The project focused on improving independence and accessibility by creating a lightweight, foldable tray that attaches securely to standard posterior walkers. My work centered on the mechanical design and prototyping. Integrating 3D-printed clips, PEX supports, and finding an effective design to make the tray simple, safe, and easy to use.
Standard posterior walkers lack a surface for carrying items, limiting users’ ability to perform daily tasks independently. The goal was to design a tray that attaches securely without affecting the walker’s stability, remains lightweight for users with limited strength, and supports up to five pounds while maintaining ease of folding and portability.
The final design features a foldable tray supported by PEX beams, 3D-printed hooks and clips, and a silicone non-slip mat. The tray attaches using a simple clip-and-hook mechanism, allowing it to lock in place for use or fold down for storage. The result is a simple (but effective) system that enhances user independence without adding complexity.
