A Product Design Based on Interaction Design and Axiomatic Design Theory

With the development of technology, the improvement of living standards, personalized designs that emphasize diversity and self-fulfillment are becoming more and more popular. As a result, designers must focus more on user needs. Traditionally, most of designers only focus on satisfying users' functional needs and often ignore users' emotional and psychological needs. This paper presents a design method that combines interaction design with axiomatic design. The proposed method first employs interaction design to acquire user needs with respect to three aspects: “people”, “products” and “environment” and then adopts axiomatic design to complete the conceptual design. The methodology is demonstrated and validated with a case study of children bicycle. The results show that the proposed method significantly enhances users' experience of the product and meets more comprehensive user needs, especially in terms of users' psychological and spiritual needs.
