QFD and TRIZ are important and famous methodologies to design. This work can show what are the main honours and the principal defects about them and their applications.

Abstract
QFD and TRIZ are important and famous methodologies to design. This work can show what are the main honours and the principal defects about them and their applications. An example was used to demonstrate this assumption, the following one. A mechanical device to control kart’s tire pressure was developed. This valve must blow air when temperature’s tire and pressure raise with a not acceptable shape deformation and a corresponding modification of the vehicles trim. With the new solution, drivers can drive faster and more safetly. Two design methods have been utilized: QFD and TRIZ. The first one, Quality Function Deployment, offers a clarification tool for organizing the information flow in a structured way, and TRIZ, Theory of Inventing Problem Solving, is an efficient tool in the discovering the solution principles. With TRIZ’s table, technical and physical contraddiction are put in evidence and eliminated to improve the robustness of the device. The two methods interact one another and offer the best path for the development of a new design.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
