The synergy of QFD and TRIZ design practice — A case study for medical care bed

The aim of this research is to integrate QFD and TRIZ theories into innovative principles of the medical care bed design. The use of QFD matrix expansion and its importance for evaluation and analysis to build the front-end preventive design process that will meet customer needs, the evaluation is based on the order of importance, the quality characteristics of the target specifications and quality characteristics of correlation matrix. The analytical data can be used to assist in resolving the conflicts of the TRIZ innovative principles to solve engineering problems and developing new concepts to meet customer's specific demands, and then apply TRIZ to define the points on anti-bedsore, perform ideality analysis and find useful resources. After doing the Table of Contradictions, TRIZ 40-principle and single characteristic principle are good to find solutions on improving anti-bedsore design. They can also provide the medical care bed design staff with more effective ways to accelerate the product development and to increase market competitiveness.
