If you wear watches, you know that getting a band to have a proper fit can usually be a challenge. A clasp can leave a band too loose, while an elastic band can pull skin hairs. And the ones that are adjustable can be too tight or too loose. Apple wants to solve that problem, and has gotten a patent to do so.
Apple has been granted U.S. Patent No. 9,781,984 for a "Dynamic fit adjustment for wearable electronic devices" that details different ways that the company will look at for creating a watch band for its Apple Watch that is easily adjustable and comfortable at the same time.
The patent describes the Apple Watch need for biometric data and that options for a proper fitting band include using the processor to adjust the band, or another device, such as the iPhone, to send instructions to the watch to adjust the band. The system would be automatic or through a tensioner adjusted by the user.
Other solutions include shape memory wire in the band, a bladder system that can expand or contract, retractable and extendable band parts within the device housing, and a ratcheting system.
With the need for the Apple Watch to get accurate readings for its heart and health monitors, a proper fitting band is essential, and the new patent would ensure more accurate readings. The company has already been moving in that direction with its new Sport Loop band that offers a hook-and-loop fastener.
