Project background / Contexte du projet
Wheelchairs are often equipped with a way of hanging a backpack or some bag on the back of the chair for transporting items. The current arrangement requires the user to reach back over their shoulder to grab the backpack and manually bring it forward to get at the contents but this needs employment of an arm motion and a hand and wrist action that many wheelchair users do not possess.

Your task is to design a system to transfer a backpack from the back of the wheelchair to far enough forward on the side of the chair for use by persons in wheelchairs who need to readily access the contents of their backpack. The device envisaged would attempt to be a backpack/bag transfer system that would be adaptable and flexible enough to work on a variety of models, looking to be as universal as possible. It should be able to operate both manually and in a powered version on both manual and powered wheelchairs. It will need to support and transfer a normally-loaded student backpack with books and a laptop. This operation should be a straight-forward overall and respect warranty requirements regarding installation (e.g. no drilling to mount components). It should also operate in a confined space and take into consideration any possible injury it could cause while moving.

Past attempts / Tentatives précédentes
Although there are prototype versions of bag transfer systems developed for manual and power wheelchairs they have limitations based on the weight of the bag that can be transferred, complicated parallel arm structure, and awkward and specific wheelchair mounting requirements and motor operation (if needed). Each unit is created for a unique type of wheelchair of which there are many versions and sizes ranging from child to adult.
