Most Critical Module

Attachment to the Wheelchair and the  Pivot Mechanism

Tricycle Attachment (Homepage)

Initial Strategy 

Final Concept 

Prototype Design 

The hinge was chosen as the most critical module, because it is the section that is the unique feature differentiating the attachment from standard tricycles.

The attachment is still based on the initial design sketch:

Two Designs are being examined for the hinge.

1. A very simple design, which involves two metal pipes seperated by PCV, to ease the rotation

2. A more complicated design that would be easier to use. It is a simple roller bearing made out of pipes of different diameters, which are separated by nails acting as the rollers.
