Research on Product Design Education Based on Evaluation Grid Method

As far as product design education is concerned, traditional classroom teaching mostly uses desktop research, simple field investigation and non-rigorous interviews as the main means, which often fails to accurately and systematically grasp users' real needs and preferences. The purpose of this study is to explore the new path of product design education, stimulate students' creativity, and ensure that the conceptual scheme designed by students accurately captures user preferences. Firstly, students are required to collect the sample data of the design object through market research and patent query, and use Evaluation Grid Method (EGM) of Miryoku Engineering to extract the attractive factors of the design object. Then, the charm evaluation of users and potential users is obtained by questionnaire survey, and the Quantification Theory Type I (QTT□) is used to analyze the questionnaire data. Finally, the correlation between the specific characteristics of the design object and the demand intention is constructed, which can be used as a reference for students to carry out design innovation. This study is helpful for students to carry out product design practice and improve the scientific and strictness of current product design education.
