감성 소재․부품 개발을 위한 감성공학적 품질평가 프레임 워크 및 활용 –필름지용 잉크 소재 개발 사례를 중심으로–

Abstract

Background: In recent process of product development, ‘the era of emotional quality’ has come to take into account the emotional sensibility of users beyond functions or performance of a product. If a design starts to consider sensibility of the users from the level of materials and parts that comprise a complete product, it will enhance the affective quality of the finished product. Thus, it is time for the design techniques to reflect users' emotional requirements for the product and the market trend at the material and component level. Frameworks for evaluating the affective quality of materials and parts also need to be established. Methods: This study proposes human sensibility ergonomic approach as a framework to evaluate the quality of the emotional design of materials and parts. This framework that utilizes semantic differentiation, factor analysis, and multidimensional scaling methods is applied on developing emotionally appealing ink materials for interior films. Result: It was found that the consumer's sensibility for the materials under the test consists of three axes : originality, oneness and stability. The results show that assessed affective quality alongside with these axes depends on the characteristics of the materials. A few design parameters that caused the difference in the affective quality are identified by through discussions with design experts. Conclusion: A framework has been proposed to evaluate the affective quality of materials and parts, and its validity is checked by applying it to the process of ink materials design. The framework is supposed to apply in the assessment of more diverse emotional materials and parts.
