The purpose of this study is to disclose the building process of suppliers' development capabilities through the patent data analysis under rapid technological system conversion of the automobile. Recent computerization of cars has urged the improvement of the technology of arranging wire harness and lightening. The role of wire harness in a car is a linking of electrical components, so it means that wire harness is to define the electrical functions of the car. Namely, wire harness is suitable as a subject to observe recent improvement process of development capabilities of auto parts suppliers. In order to visualize research results, we use a patent data analysis of the wire harness area. Research subject is wire harness department of the Sumitomo group (Sumitomo Electric Industries, Ltd., Sumitomo Wiring Systems, Ltd., Auto Network Technology Institute), which has extended global market share over the last two decades, while comparing with the Yazaki Group (Yazaki Sougyou), a top supplier of wire harness. In analyzing the patent data, we regard a company as a bunch of technology and analyze from 3 viewpoints, which are companies, engineers, and invention. Our study revealed the following mechanisms.Mechanism 1, Analysis of Company unit: “Building development capabilities starts from the patent application by wire harness manufacturer alone.”Mechanism 2, Analysis of Engineer unit:“The key to build development capabilities is the reciprocating motion between single application and joint application by core engineers.”Mechanism 3, Analysis of Invention unit: “Building development capabilities accelerates by reconstructing the predecessor's technology.”We present a conceptual model that organizes the mechanism as the conclusion of this study. "Building development capabilities starts from patent applications by wire harness manufacturer alone and returns to the evolution path of the invention by the reciprocating motion of the core engineer as an interface, and accelerates by reconstructing the predecessor's technology."
