Design improvement of off-road rough uneven rural terrain wheelchair

This design study reviewed the redesign of a manual wheelchair for the rural terrain where difficulties are faced in maneuvering the currently existing wheelchairs due to uneven and rough terrain particularly with sandy, sloping ground, and poor road system which makes moving almost impossible. Possible concepts which address these challenges were developed, evaluated and improved to come up with a mechanism that takes into account the lack of balance and difficulty in maneuvering. A detailed design was done including the calculations, generation of drawings of the component parts and sizing of the parts of the wheelchair. The wheelchair was designed for occupants of healthy upper torso with pelvic to foot restraint.
