A Study on the Diagnostic Method of Lineup Flow and Core Design Area to Secure Design Identity

Background This study explores a strategic diagonal way to secure design identity from a homogeneity and continuity context. Therefore, the forehead part of a high-speed train was selected as the subject of this homogeneity experiment shape and longer life span. In addition, we analyzed the trend of lineup models from the initially-released prototype to more recent models. The outcomes are illustrated in a diagram as a 3-dimensional structure that is capable of diagnosing the design identity. Methods We organized the discussion on design identity and developed a research model in consideration of homogeneity and continuity based on existing studies. Specifically, we surveyed researchers in the design sector and examined quantitative data extraction. We also applied a homogeneity analysis, through multi-dimensional scaling. In addition, we investigated the point of product release time, applied a 2-dimensional positioning map, and examined a final lineup flow and routes. Results We analyzed and schematized the homogeneity analysis and lineup model flow to show the design identity diagonal process. First, based on the homogeneity analysis, we schematized the core design area. Second, we found that by centering on the initially-released prototype, with time, the lineup flow formed in a spiral shape. We estimated that such a flow signals and that the released models changed continuously in a gradual manner while they maintained homogeneity on the initial model. Conclusion The discussion above is organized by identifying the core design areas in the homogeneity aspect. The 3-dimensional flow in the continuity aspect also can serve as a strategic foundation to diagnose the company’s lineup flow and deviation models. In addition, the findings are highly applicable as a strategic diagonal method to secure design identity of high-speed trains and other products. Furthermore, the findings can be utilized as a professional approach for design identity and lineup diagnosis in relation to other competing companies.
