At the 2023 Pollen Annual Meeting, Yu Chengdong joked about plagiarism by friends, saying that he didn’t respect our (Huawei’s) intellectual property rights very much, so he just made up a name and said it was his own.In Yu Chengdong's view, the double-rotation water droplet hinge directly becomes the keel hinge, and the keel does not exist.
Xiaomi responded that the "keel hinge" is a new generation of folding hinges independently developed by Xiaomi Group. It is the first in the industry to have a 3-level rod structure, which brings more precise, stronger and more reliable folding quality.
Whether it is the design idea or the mechanical structure, Xiaomi's self-developed keel shaft is completely different from the so-called "double-rotating water drop hinge" claimed by Mr. Yu Chengdong. Mr. Yu Chengdong please follow the basic rules of "science and rigor" and stop discrediting his peers and misleading the public.
This also triggered a heated discussion among netizens. Is it plagiarism or not? Some netizens also flipped through the "China Patent Announcement", and the data showed:
1. Xiaomi keel shaft corresponding patent number: CN212297248U
2. Patent number corresponding to Huawei’s water droplet shaft: CN116074415A
Judging from the comparison patent drawings of the two, there are indeed design differences between the two parties. Although both have a U-shaped (water drop-shaped) structure, Xiaomi's lower structural part is a pole, while Huawei's lower structural part uses a knob.
So, what do you think?
Huawei patent
Xiaomi patent
