An Extensive QFD and Evaluation Procedure for Innovative Design

الملخص EN

In this paper, a systematic innovation procedure has been developed based on quality function deployment and extension method.

Besides, the evaluation method for design decision making has also been discussed and developed.

The major procedure of QFD is to identify the customers’ needs for the product and then convert into appropriate technical measures to fulfill the needs based on the company’s competitive priorities.

The priorities of product characteristics can be obtained by translating important technical measures.

According to their characteristics, the prior engineering parameters will be identified and selected as the key requirements to redesign.

This paper will focus on the integration of QFD and extension method.

With the help of “matter element theory and extension method,” customer requirements (CRs) can be transferred into product design attributes more comprehensively and deeply.

According to the idea of loss function of Taguchi quality design method, the criteria for design decision making have also been developed in this paper.

An innovative design case, bicycle, successfully demonstrates that the proposed design process is feasible and efficient.
