Recently, Xiaomi responded to the remarks made by Yu Chengdong, the director of Huawei, angry at Yu Chengdong's false accusations. Xiaomi issued a statement through its official Weibo account, expressing strong dissatisfaction with Yu Chengdong's remarks and pointing out that his remarks are seriously inconsistent with the facts. The controversy centers on the two companies' folding phone technology, with Xiaomi claiming that its self-developed keel hinge technology is completely different from the dual-spinning waterdrop hinge claimed by Yu. In the statement, Xiaomi detailed the differences between the two technologies and provided patent applications and public information as evidence. Xiaomi also urged Yu Chengdong to follow scientific and rigorous basic rules and not to denigrate his peers and mislead the public.
Xiaomi refuted Yu Chengdong's remarks one by one, first pointing out that the keel hinge is a new generation of folding hinge developed by Xiaomi Group, using the industry's first 3-level rod set structure. This innovative construction results in a more precise, stronger and more reliable folding quality. In contrast, Yu Chengdong's claim of the double-spin waterdrop hinge adopts a design scheme of 2-stage rod group, 3 members, and 4 low pairs, which is completely different from Xiaomi's keel hinge mechanical structure.
It is worth mentioning that Xiaomi mentioned in the statement that they have researched and verified patent applications and public information. Xiaomi said that the patent application for their self-developed keel hinge was filed on September 18, 2020, and the patent was granted on January 5, 2021. The patent application for the double-spin droplet hinge mentioned by Yu Chengdong is relatively backward, filed on December 13, 2019, and published on June 18, 2021. This shows Xiaomi's advanced and leading position in folding phone technology.
In the statement, Xiaomi also pointed out the patent situation of Yu Chengdong's company. According to publicly available information, Yu Chengdong's team's patent application for the ** pole set was submitted on October 29, 2021, but it has not yet been authorized and has not been productized. In contrast, Xiaomi's keel hinge technology has already been applied for the first time on the Xiaomi MimixFold 3 in August 2023.
Xiaomi stressed that this information fully illustrates Yu Chengdong's claim about Huawei's dual-spin waterdrop hinge technology, which is seriously inconsistent with the facts. Xiaomi hopes that Yu Chengdong will abide by scientific and rigorous basic rules, and stop smearing his peers and misleading the public.
Through Xiaomi's response to Yu Chengdong's remarks and the collation of the statement, we can see that Xiaomi has full confidence in its technological innovation and patent application. They insist that the keel hinge technology is a new generation of folding hinges developed by Xiaomi Group, which is completely different from the dual-spin waterdrop hinge claimed by Yu Chengdong. By citing patent applications and public information, Xiaomi provided conclusive evidence to support its view. The patent situation of Yu Chengdong's team has also been revealed by Xiaomi, which has not yet been authorized and has not been productized, and compared with the Huawei technology claimed by Yu Chengdong, there is a significant gap.
Overall, this debate is not just about the competition between the two companies, but also about the innovation and authenticity of the technology. In the highly competitive technology industry, companies are looking to get one step ahead and launch products with unique ideas and high quality that will be recognized by the market and favored by consumers. But while pursuing technological breakthroughs, we should also adhere to the principles of science and rigor, not at the expense of authenticity, and avoid bringing inaccurate information to the public.
Technological innovation requires authenticity and respect, and only in this way can the healthy development of the entire industry be promoted. It is hoped that the future competition will pay more attention to technological innovation and provide consumers with better products and services.
