QUANTITATVE DESIGN METHODS FOR KANSEI IN AUTOMOBILE DEVELOPMENT

Abstract

The use of quantitative design methods for KANSEI is an effective way of determining an accurate design solution in a short period of time. They are now being studied in conjunction with advances in CAE (Computer Aided Engineering), CE (Concurrent E ngineering), and other systems for application to product development.
This paper first introduces four examples of quantitative design methods for KANSEI from automobile research and development. The examples are “Deign Method for Seating Comfort”, “Coordinated Illumination System”, “Method for Evaluating Roominess in a Vehicle's Interior”and “Switch-Operation-Feeling Evaluation System”. It then exmines the features of these design methods and finally explains the need for systematic development and application in the form of a “gray box model”that combines quantitative design methods with qualitative design methods.
At present, there is a demand for placing high value on KANSEI in automobile development, and on the other hand, a great need for efficient product development from the point of view of corporate management. The appropriate selection of KANSEI design methods in terms of both results and efficiency is becoming a major issue in automobile development. To carry this out successfully, the application of KANSEI design methods must be strategically addressed with future plans made clear.
