Zhongxin Jingwei, December 12 At noon on the 12th, the official Weibo of Xiaomi Technology Co., Ltd. said, "Recently, Yu Chengdong has unjustifiably made false remarks about our company's keel shaft technology, which is seriously inconsistent with the facts. ”
Xiaomi said that whether it is the design idea or the mechanical structure, Xiaomi's self-developed keel hinge is completely different from the so-called "double spin water drop hinge" claimed by Yu Chengdong. After studying the technical information and published patent information disseminated by Yu Chengdong's company, and verified by actual dismantling, the so-called "double spinning water drop hinge" adopts the design scheme of "2-level rod group, 3 components and 4 low pairs", while the "keel rotating shaft" mechanical structure developed by Xiaomi adopts the design of "3-level rod group, 5 components and 7 low pairs".
Xiaomi also said that the self-developed "keel hinge" applied for a patent on September 18, 2020, and was granted a patent on January 5, 2021, and was first applied on the Xiaomi MIX Fold 3 in August 2023. The so-called "double-spin water drop hinge" claimed by Yu Chengdong applied for a patent on December 13, 2019, and was only disclosed on June 18, 2021. It can be seen from this that Mr. Yu Chengdong's remarks are completely inconsistent with the facts. ”
Xiaomi mentioned that according to publicly available information, Yu Chengdong's company's patent application for the ** pole group was applied for on October 29, 2021 and made public on May 5, 2023.
Xiaomi finally said that Yu Chengdong is requested to follow the basic rules of "science and rigor", and do not smear his peers and mislead the public.
