Fully automated paper towel holder
grabcad
This prototype, due to time constraints, remains incomplete; however, it showcases an automated shearing process. The product incorporates rack and pinion mechanisms, plus ratchet freewheel mechanisms. Upon pressing the spring-loaded handle, connected to the free wheel mechanism via a rack and pinion setup, the paper towel rotates. Releasing the handle results in the handle's return while the towel remains stationary due to the free wheel feature. For shearing, press down further on the handle to activate the spring-loaded blade (pink component). Please let me know if my explanation is clear, and apologize for any shortcomings in this submission.
