자동차용 고급 플라스틱 내장재의 특허분석으로 살펴본디자인에서의 고급감 가치 분석에 대한 융복합 연구

In recent years, automotive industry has been increasingly demanded to develop various functions and designs with high quality by development of new vehicles such as shared vehicles, multi-purpose utilization of automobile spaces, and door-to-door transportation means. In this study, the luxury value in the design of automotive industry would be performed according to the characteristics of plastic interior materials. The purpose of this study is to suggest new convergence methods which can analyze the luxury value systematically comparing and analyzing by using the patent analysis technique which has been mainly used in technology trend analysis, new project planning and the investigation of corresponding patent based on extensive and objective patent data. The results and contents of the study are as follows. First, we analyzed the patents related to premium plastic interior materials for automobiles. The current status and characteristics of the patents filed with the Japanese Patent Office for the past five years (2012 ~ 2016) by year and applicant are described. Second, the technology trend of premium plastic interior material for automobiles was described. We have analyzed the application status of various polymers used in plastic interior materials, and described the current status of each application area of ​​automobiles, and the technology trends according to manufacturing process and processing technology classification. Third, based on the analysis of the effect of invented patent inventories, we applied the six major target value classification criteria of luxury quality in design to perform a luxury value analysis. By using these luxury value analysis standard, we analyzed the application frequency of polymer and processing technology in each luxury major target value categories and investigated the correlation between each luxury value categories and related material technology. In conclusion, based on the analysis of Japanese patents for the last 5 years, we examined the technology trends of premium interior materials for automobiles according to the materials, application areas, and processing techniques. Based on this analysis, a method to analyze the luxury value in design was suggested.
