Handrims and pushrims are essential components of wheelchairs that facilitate mobility for individuals with mobility impairments. Handrims refer to the circular rings attached to the outer surface of the wheels, while the pushrims are the rings used by the rider to propel the wheelchair. Designing handrims and pushrims requires attention to several criteria such as material, size, shape, and texture. Firstly, the material should be lightweight, durable and easy to clean, such as aluminum or titanium. The handrims and pushrims should be available in various sizes to fit different wheel sizes and hand sizes. The shape of the handrim should be ergonomically designed to reduce stress on the user's wrist, elbow or shoulder during propulsion. It should also follow a circular shape to ensure smooth movement of the hand, without sudden curves or bends. The grip surface of the pushrim must have sufficient texture and grip to ensure a firm and secure grip. Designers can also incorporate additional features to enhance the functionality and comfort of handrims and pushrims. For example, specialized coatings or treatments can be added to provide extra grip and comfort or reduce friction. Additionally, pushrims can be designed with a deep rim profile or flares to accommodate various hand positions and grip styles. Lastly, designers can consider integrating sensors or power assist technology to reduce the effort required for manual propulsion. In summary, the design of handrims and pushrims is crucial in ensuring the comfort, mobility and safety of wheelchair users. Designers must consider materials, sizes, shapes, textures, and additional features to create effective, ergonomic, and user-friendly handrims and pushrims.
