HUMAN DESIGN TECHNOLOGY USING QUALITY FUNCTION DEPLOYMENT AND ITS APPLICATION

抄録

Due to the diverse user requirements of products, it has been important to develop the products to satisfy them. Human design technology (HDT) constructs a structured concept of a product and clarifies and evaluates the product functions required by users. However, this design method is mainly applied in the early design process and is not so effective in the late one. This paper proposes an improved HDT using Quality function deployment (QFD) that enables the designers to extract the design elements considered in both early and late processes and to analyze the relationships between them. The proposed HDT enables the designers to consider the engineering characteristics of design objects and to comprehend the relationships of the whole design elements regarding the product development in order to proceed to the late process of design. Additionally, a design example is presented to demonstrate the proposed HDT and to indicate the method seems to be effective not only in proceeding to the late process of design but also in generating new product concept.
