Innovative design of water boilers based on QFD and TRIZ

Based on the characteristics of Quality Function Deployment (QFD) and theory of inventive problem solving (TRIZ), an innovative design model based on QFD and TRIZ is proposed. Firstly, customer requirements are analyzed by the House of Quality. The problems that need to be solved in the design are identified. Then, the innovative design scheme of the product is obtained by applying the corresponding TRIZ' innovation principle. Finally, the model is applied to the innovative design of water boilers. The validity of the model is verified.
