The application of Function Analysis in development of rehabilitation product

Rehabilitation product is something that can help the persons with disabilities to solve the challenges with necessary functions. The development of rehabilitation product is the important subject with complex process in rehabilitation engineering, which would use cross field knowledge. Conceptual design is the key process for new product and function analysis is the main job for the engineers to locate the solutions. The result of conception design is to generate design scheme. The function analysis usually contents function definition, function decomposition, function chain analysis and function model. Finally, the process and significance of function analysis is illustrated with an example rehabilitation robot. Function analysis can help the rehabilitation engineers for problem analyzing and it is the base for the detailed design in the next step.
