Single Arm Jar Opener

SJSU ME 20 - Single Arm Jar Opener Project

Feb 2021 – May 2021

Together with two other class peers we approached the problem of how to design an apparatus that will aide those with physical impairments.

- Project was sponsored by AutoDesk, Delve, and SJSU

- An iterative process of creating sketches and 3D models of potential designs

- Collaborative process in the design, presentation, and brainstorming phases of the project

- Created 3D models, standard view drawings, and assembly of the finish product in SolidWorks and Fusion 360

Team 6 Final Concept Submission

With this design concept the user places a jar of any size onto a platform that is fastened to a counter and utilizes the weight of the jar and the applied force from the user to push down on the jar, causing the normal force from the surface position the two clamps tightly around the jar and allowing the user to twist off the lid of the jar with a single hand. The advantage of this design is that it mimics how people actually open jars (pushing down on the lid and twisting) so the product will feel very intuitive. The harder the user pushes down on the lid, the tighter the clamps will grip the jar, and the more force the user to apply to twisting off the lid without slipping.
