Abstract
To increase user satisfaction index and achieve rapid innovation in new ergonomic product development, a multidisciplinary model integrating method of User-Centered Design (UCD) and theory of innovation problem solving (TRIZ) eight evolutionary patterns for ergonomic product innovative design in the early design stages was proposed. The integrated model and the approach procedures consists three steps. In step 1, three ergonomic needs dimensions integrated with UCD are utilized for identifying thorough user needs (UNs). And 5-point liner numeric rating scale is used for establish the relative importance of UNs. The internal consistency reliability of UNs is tested with Cronbach’s coefficient alpha statistic. Then the final UNs is established as well as the UNs priority. In step 2, the Eight Patterns of Evolution of the TRIZ are selected to generate design idea, with the UNs priority. In step 3, innovative design alternative is generated by using design idea together with the ergonomic design principles. Finally, a case study of the electric moxibustion device innovative design is conducted to demonstrate the feasibility of the proposed model and approach.
