Mehrab’s team goal: Our goal is to design and create a
spinning device for the client to lay down on and sit up
in to help their vision.
The project is to create a structure that is able to spin at a
speed to aid the client’s vision (manual or auto). The chair
will be able to lay flat and to able to rise to the client’s need.
The device needs to be portable so that the client can transport the device.
Needs: Able to lay down
Adjustable chair
Strip across chest and lumbar
27 in. diameter at least but can be bigger to allow growth
Portable
*Vibration
*Swing
Solid Colors
Background Research: Gaming chair
Merry-go-round
Beach chair
Sliders
Concept 1: Spinning chair with shaft and bevel gears
Concept 2: Merry go round Chair
Concept 3: Chair with Slider Wheel
Selected Concept Design: Concept 1 Spinning chair with stand
The Chair will be able to rotate because of our enclosed bearing called a lazy susan. The base of the chair will be connect to the bottom of the lazy susan, and the base is a plate welded to (most likely aluminum) tubing with 4 triangle and same for the bottom. On top of the lazy susan, there will a plate with pipes standing in the middle for the chair to slide into and a frame to allow a chair to rest. The ability to recline the chair is a mechanism found in most car seats. The chair will be a gaming chair and on the bottom will a plate bolt to it a pipe extending to able to slide into the pipe on the base.
Engineering Analysis 1: The goal the center of stability for center not to tilt. Sum the force in downward direction, we were able to find to distance for the base to be set for stability.
Engineering Analysis 3: The goal is to find the total weight of the base, the lazy susan, and platform for the chair. The importance of this analysis is to find portability of the structure so that the client can easily move it from one location to another.
