Problem Statement
Determine a way to mount the motor onto a door.

Design Requirements
The motor must be mounted to the door. However, no changes can be made to the door. No hooks, nails, or screws can be used directly on the door. As such, the motor will be mounted to a piece of wood, which will be attached to the door using ratchet straps. The ratchet straps were ordered from Amazon.

Equipment and Materials Used
Plywood (11 3/4" x 9 1/4") and ratchet straps will be implemented in this design. The dimensions of an engineering notebook were used as the basis for the plywood piece, since this is large enough to fit the motor.

The initial piece of plywood was 15" x 32". This was bought from Home Depot. A Ryobi circular saw was used to cut an 11 3/4" x 9 1/4" piece. When using the circular saw, safety is paramount. Safety goggles were used, and the workspace was clear of any debris.

The Design
The motor will be screwed onto the 11 3/4" x 9 1/4" plywood piece. This piece will be attached to the door using ratchet straps. The motor will be attached to the door handle using a string. This string will pull down the door handle when the motor turns.

The ratchet straps had not arrived as of 3/27/2013.
