美國輕負載汽車輪胎胎紋專利分析
An Analysis of the U.S. Tire Tread Patents of Light Loading Vehicles
摘要
本研究藉由對全球前五大輪胎廠普利司通、米其林、固特異、倍耐力與德國大陸所擁有的美國胎紋專利分析研究，了解這些公司在產品上的優勢，發掘這些公司在技術研發上的重點與趨勢。並與台灣五大廠商在美國的胎紋專利做比對，給台灣廠商研發上的建議。 研究結果顯示普利司通與固特異對專利的投入遠勝其他三家廠商。五大廠發明專利技術的兩大重點在橫溝紋設計與溝槽深度方向上的研究。強調的功效主要為抓地力、排水性、磨耗均勻、操控與噪音五大項。 台灣廠商部分只有正新輪胎有符合本研究的14筆新式樣專利而無相關發明專利。正新與其他大廠的功效對比並無太大差異，多集中在抓地力、排水與操控三大項。在技術方面，正新沒有溝槽深度方向與胎穴的專利。但從發明專利所代表的技術發展而言，溝槽深度方向是現今胎紋設計主要的重點之一，建議台灣廠商應列入未來的研發重點。

The goals of this study are to investigate the U.S. tire tread patents owned by the five major tire manufacturers, Goodyear, Bridgestone, Michelin, Pirelli and Continental, to identify the advantages of the tire treads of each of the major manufactures, and to compare the Taiwan-based manufacturers to the major ones. The results show that the Bridgestone and the Goodyear have more patents than others. The major two technical issues of utility patents are lateral groove and groove wall direction. The effects emphasized by those utility patents are traction, drainage, even wear, steering stability and noise control. Cheng Shin Rubber Ind. is the only Taiwan company which owns U.S. tire tread patents. 14 design patents owned by Cheng Shin Rubber Ind. are found. The patents show no different effects compared to the five major manufacturers. The main effects of its patents are traction, drainage and steering stability. Cheng Shin Rubber Ind. has no patents about groove wall direction and notch, one of the most important aspects of tire treads. The author suggests that Taiwan companies carry out more researches in these domains.
