Ergonomic Design Based On QFD And TRIZ Theories

Ergonomic design is aimed that there is no or less in ergonomics issues, when products are in the production or use. To achieve this only after product design was completed or even was produced before research on human-computer products. It is a dilemma of ergonomic design. If it is found a problem, the only choice is either to re-design and manufacturing, or to adopt some additional structures to improve in order to achieve a compromise. These two methods will waste tremendous human and material resources and innumerable time of design and manufacture, will also increase product development costs and slow the pace to the market.Through the study of QFD and TRIZ theories, it is found that QFD and TRIZ theories provide a process improvement methodology of innovative ergonomic design. This paper proposes on using QFD to integral ergonomic design into product design processes, finding problems at all stages of the human factor analysis, and then applying TRIZ to solve the complex problem. Besides, this paper will give a specific example from personal participations in product development to explain the application process and methods.
