Project Summary Project Information

State of Wheelchair User-Assist Devices:

Users of manual wheelchairs often have trouble moving up inclines due to the proclivity of the chair to roll backwards down the slope. Wheelchair users also have problems moving safely down slopes due to the difficulty of slowing the chair down. These problems could be solved by the use of a power wheelchair but the size, weight, and lack of maneuverability makes it difficult to use in the home. Our project is to create a device that will combine the best traits of both a manual and power wheelchair. Our goal is to make a system of devices that will stop the wheelchair from rolling back down an incline and slow down the chair when moving down a decline. We will call these devices “Hill Holder” and “Gradual Grade,” respectively.

Our Project Goals:

The primary requirements of the prototype are to stop the user from rolling back down an incline and to help the user with slowing the chair when moving down a slope. The prototype is expected to be easily retrofittable to most existing manual wheelchairs, be available at a much lower cost and weight than comparable alternatives, and be easily disengaged by the customer. The prototype must not add significant resistance to the forward motion of the chair and it must be able to prevent unexpected tipping over of the chair on steep grades.
