A Kinematic Model Used to Customize Design of Manual Wheelchair


Article Preview

That wheelchair user’s shoulder joint injuries are directly related to poor wheelchair design and the location of the wheelchair driving mechanism has been proven clinically. This work presents a novel approach to rapidly customize the design of manual wheelchairs, such that each user can easily obtain a custom manual wheelchair, thereby reducing the potential for shoulder joint injury. In this study, a human-chair system composed of a human body and a wheelchair was simulated as a plain single-loop five-bar linkage. Mobility analysis was conducted to identify the corresponding joint workspace. By analyzing linkage movement and the upper-limb muscle strength of a user, the optimal location of the wheel hub and optimal radius of the handwheel were identified as the bases of a customized design for manual wheelchairs.
