Concept Design: Motion options

• Rack and Pinion: The first idea of a mechanism to open and close a window was a simple rack and pinion gear assembly. The window will sit on the rack of the assembly where the pinion gear, connected to an electrical motor, moves the rack with the pane causing it to open or close.
• This idea was rejected for many reasons. This assembly is noisy and causes discomfort to the residents of the room. Another reason we rejected this mechanism is that it uses a lot of power to operate. And a third reason is that it would be unappealing from an architectural point of view.
