PRODUCT DESIGN METHOD, PRODUCT DESIGN DEVICE, AND MEDIUM FOR STORING PRODUCT DESIGN PROGRAM

摘要

PURPOSE: A method and a device for designing product and storage medium for storing a product design program are provided to capture and refine the wants and needs of users with respect to a particular product and quickly and easily define an optimal product concept that appropriately reflects those wants and needs and that is capable of eliciting a high level of user satisfaction. CONSTITUTION: In the process associated with an embodiment, wants and needs information which has been input is analyzed(S20), and, based on the analyzed wants and needs information, weighting is carried out with respect to evaluation indices which have been previously stored in a storage device and which are quantitative measures of the degree to which the user is likely to perceive a benefit latent in the product under consideration and inherent in the aforesaid wants and needs information to have been achieved(S30), one or more evaluation index or indices having the highest weighting among a plurality of such weighted evaluation indices is or are selected as a primary evaluation index or indices (S40), and a product design concept or a plurality of product design concepts for which the primary evaluation index or indices so selected is or are a maximum or minimum is or are defined(S50).
