Back Scratcher
Fall 2009: Engineering Design Course
For the Engineering Design class EID103 Mark Lee, Matthew von der Lippe, and I made a back massage and scratch chair. The goal of the class was to design a device to help assist the elderly and handicapped. In that vein we chose to design a back scratcher that would allow the user to pinpoint a specific spot on their back using only their hand (via a control panel).
The chair was built on a very large scale to accommodate users of all sizes. The control panel, located on the right hand side, had two separate switches for the up-down and left-right motion.
The up and down motion was achieved using a much larger threaded rod and a drill.
The left to right motion was achieved with a threaded rod and an electric screw driver.
