Proposal of design support method for timeaxis design using patterns between temporal changes and countermeasures

Abstract

Since the current manufacturing paradigm cannot get out of the mass production and mass consumption in correspondence with diversification and expansion of customer needs, today's manufacturing industry causes many problems such as sustainability issues typified by SDGs. The conventional design theory seems not to be sufficient for these problems because it does not deal with temporal changes of design objects. For solving this issue, we study “timeaxis design,” which explicitly deals with temporal changes in design. This paper proposes a timeaxis design (TaD) support method using patterns between temporal changes and countermeasures. First, we extract patterns of temporal changes and countermeasures to them from collected TaD cases. Next, we propose a TaD support method using these patterns. Finally, this paper illustrates timeaxis design of bicycle as a case study using the design support method. The TaD support method enables designers to design a product with introducing countermeasures against plausible temporal changes into design objects. The case study indicates that designers can find out TaD design solutions systematically using the proposed method.
