Abstract Product competition was depended on the competition of design and manufacture technology level in the final analysis．No other than applying new idea，adopting new theory，method and principle in design processes，product design quality will be increased，realized design innovation and therefore construct competitive advantage on the market．QFD method was guided by customer’S needs；the key techniques，which affected product quality，were found by QFD．The full new theory for inventive problem solving is TRIZ；it is a very powerful idea to bring technique innovation to success．Taguchi’S method iS a feasible tool to transform innovative result into inexpensive but elegant product．Based on contrasting and analyzing the characteristics of these three methods in detail，the integration of QFD，TRIZ and Taguchi’S method was put forward，it will exert each advantages farthest，compensate each shortages，and thereby realize design quality innovation for satisfying the customers．

设计质量创新——QFD、TRIZ和田口方法的集成应用
产品竞争归根到底是设计与制造水平的竞争，只有在设计中运用新的思想，采用新的理论、方法和原理，才能提高产品的设计质量，实现创新，从而构筑竞争优势．QFD方法以顾客需求为导向，从顾客出发寻找影响产品质量的关键技术．TRIZ理论提供了一种全新的解决创新问题的思想，实现技术创新．田口方法为创新成果转化成物美价廉的产品提供了切实可行的应用工具．在比较和分析3种方法各自特点的基础上，提出了QFD、TRIZ和田口方法的集成应用的设计思想，它将最大限度地发挥各自的优势，弥补不足，从而实现设计质量创新．
