An innovative design of energy-saving products based on QFD/TRIZ/DEA integration

Studying the application and development status of QFD and TRIZ theory, the paper proposes a new innovative design method of energy-saving products to overcome the shortcomings of traditional theories. This new method, which bases on house of quality of QFD, uses TRIZ theory to solve problems and DEA to select solutions. At the end it's obtained with practice that this method is effective.
