A Kansei database framework for the delight design platform

Abstract

The delight design platform (DDP) is a vision of a new integrated design environment that would enable design engineers to consistently design delightful products. Such delightful products satisfy an attractive quality as well as the performance and must-have qualities of the Kano model. The attractive quality depends on a customer’s subjective evaluation involving emotion. To implement DDP, we aim to develop a model-based design (MBD) environment that can simulate a customer’s affective responses toward digital design models. With this environment, a designer can test their ideas in the early-design phase. In this article, we propose a Kansei database framework as an essential component of the DDP. The Kansei database stores functions that estimate the customer’s emotional responses to the design model. We propose a Kansei database structure including two indexes, perception and delight, with a delight map as a visualization scheme. Furthermore, we propose a methodology to create the indexes.
