컨셉디자인을 위해 디자이너들이 사용하는 디자인 제한점들

Background In the product design field, different stakeholders communicatewith each other with design constraints. This paper reports on how designers usedifferent constraints in the sketch phase. Methods Senior students majoring in industrial design participated in thedesign experiment. Their idea sketches and interview data were collected, whichwere then categorized with a coding scheme developed from Lawson's designproblem model. Results There are three major findings. First, unlike architects, productdesigners consider not only 'designer constraints', but also other generators'constraints in the sketch phase. Second, the constraints related to the interactionbetween users and objects mostly fall into external constraints. This reflects thefact that most user interactions with products occur on the surface. Lastly, fewerconstraints in client and legislator categories are adopted while a large number ofconstraints in the user category are used by designers. Conclusion Based on the findings, we argue that if Lawson's model is applicableto the product design field as well as architecture, it needs to be modified orfurther developed by considering the characteristics of product design that aredifferent from those of architecture.
