초기디자인 단계를 위한 매개변수 주도형 디자인 지원 모델 개발

In product design, the initial phase is regarded as the most crucial as well as the weakest part. Although previous studies on the model development for the first phase have been dedicated, limitations remain. It is not suitable for processing qualitative parameters from convergence aspects from the following domains: market, user, aesthetic, and engineering. Also, the parameters are processed independently without interrelationships between each other. This prevents a sound understanding of the purpose, role, and meaning of each performance, resulting in defects·errors in interpreting pentameters. This leads the yield of parameters inherent in ambiguity·uncertainty. This study aims to develop a parameter-led design support model for the early phase. Adopting the principle of processing parameters in “Theory of Technical System”, the model has been structured with product design progress attained from interview case studies. Parameters yielded in the previous performance act as input values to the subsequent performance, in which parameters produced from those two performances are linked. This contributes to reducing the uncertainty and antiquity inherent in qualitative parameter processing in the initial design phase.
