Co-design method for concept design using a generative tool: a case study for furniture design

초록

With the emerging technologies of Industry 4.0, the concept of mass personalisation (MP) has been proposed and made major progress. However, little effort has been made to achieve MP in physical products, particularly regarding aesthetic features. Therefore, a co-design method is proposed that actively involves customers in the concept design phase. The proposed method is composed of three stages: 1) Develop a generative tool: This includes eliciting the product's perceived attributes (PA) that affect customer satisfaction; 2) Identify personal needs: Customers produce personal designs using a generative tool; and 3) Concept design: A designer iteratively sketches concept designs and obtains feedback from the customer to evaluate the concept design. The effectiveness of the proposed method was verified in case studies on three types of household furniture: chair, pendant light, and tea table. The results showed that the method was effective for customers who did not have an exact image in mind.
