Abstract

Scissor Lift
Scissor Lift

Our client,“Z,” is an 8-year old girl who uses a wheelchair due to a spinal cord injury. She is able to transfer onto a platform at the same height as her wheelchair but two people are needed to assist her in moving between her wheelchair and the floor. Once on the floor, Z has ample arm strength to easily move around. Our client would like to be able to transfer onto the floor and back up onto her wheelchair with the help of just one assistant. This would allow her to participate in classroom activities on the floor and play with her younger sister at home.


Solution

The goal of this project is to create a device that allows the client to move between her wheelchair and the floor with the assistance of only one other person. The device has a platform that moves up and down to transport Z between her wheelchair and the floor. Its principle of operation is similar to that of an adjustable office chair. If the user depresses the lever while sitting in the chair, the gas spring can be compressed and the seat lowers. If the user removes their weight from the seat and depresses the lever, the gas spring will extend and the seat will rise.
