Japan will never loosen the nut. Why can't the principle be disclosed and imitated?

Japan will never loosen the nut. Why can't the principle be disclosed and imitated? There is a saying that most excites the Chinese people's nerves: you can't create "Japan's never loose nut" for your principles and drawings! However, I can pat my chest and tell you that if there are drawings, Chinese people can make such nuts. In order to gain attention, most of the online We Media would not hesitate to use the title of "Never stop saying amazing words" to attack the confidence of Chinese people. However, this kind of nut can not be made by the Chinese, even by the Japanese themselves or by the Germans who also have deep manufacturing skills with Japan. Hadlock nut, what's the secret that can't be copied? Japanese Ruolin Keyan participated in an exhibition as a company employee. He brought back some samples at the exhibition, and one of the anti whirl nuts attracted his attention. This kind of nut, which uses stainless steel wire as clamp to prevent looseness, is complex in structure and expensive. If Lin Keyan gives full play to the craftsmanship spirit of the Japanese and ponders over the question, "Can't it be simple and cheap?". Later, in 1961, he designed an anti rotation nut, which he called "U nut". The locking principle of the U nut is to prevent the relative rotation of the nut and bolt through the elastic strong pressure between the friction plate integrated with the nut and the bolt thread surface. If Lin Keyan founded a company - Fuji Precision Manufacturing Institute - to produce and sell his new nuts, this kind of nuts will soon gain a foothold in the market. If Lin Keyan is also very confident in his design, he has put forward the advertisement of "never loose nuts". However, some customers complained that the U-nut was loose on the excavator and pile driver. If Lin Keyan left the company he founded in order to adhere to his belief of "never loosening up", he tried hard to think of ways to improve. In 1973, if Lin Keyan looked up at the tall archway at the entrance when he was passing by the Tsuyoshi Ta She (Tsuyoshi District, Osaka City) near his home, he suddenly thought, "If you put a wedge into it, it will not loosen". So he designed a structure integrating hammer, wedge and nut according to the principle of driving wedge.
