An Integrated Musculoskeletal Motion Analysis and Quality Function Deployment in Lower Limb Leisure Exercise Product Design

摘要

The promotion of social living quality has expedited the development of leisure exercise products. However, most young people usually accomplish their tasks by sitting in front of the computers. This situation makes many people seriously deficient in exercises that may cause muscle skeleton declination. In review of current related products, most of them are primarily designed by designers' intuition or only for a specific purpose. The objective of this research is to involve the motion analysis of physical musculoskeletal system in the integrated development process of quality function deployment for the design of lower limb leisure exercise products. A four-stage of development procedure including performance ranges of muscle-joint activities, AIO life style questionnaire, factor analysis, and quality function deployment is conducted. The implementation of quality function deployment helps to link customer requirements with product characteristics and derives design criteria for generating design alternatives. Two design alternatives based on the design criteria are generated by the computer-aided design software. It is expected that this research will provide designers with a reference or norm on designing most suitable lower limb leisure exercise products for people.
