Recently, the smart ring market has undergone a new transformation. A patent submitted by Xiaomi to the China National Intellectual Property Administration (CNIPA) showcases an innovative design concept that effectively addresses the issue of ring size. According to a report by 91mobiles, Xiaomi's design employs an 'elastic component' combined with a spring mechanism, allowing the ring to dynamically adjust its size based on the user's finger. This design within the patent enables the smart ring to automatically adapt to different finger sizes, allowing users to wear it on various fingers and even share it with friends.
