Apple Files Patent for Manual Winding Mechanism for Apple Watch
Many companies file patent applications for various innovative and revolutionary ideas. Apple filed a patent application for a manual winding mechanism that would generate electricity and expand battery life on Apple Watches.
The patent application describes a device charging mechanism for generating electricity through winding, similar to traditional wristwatches. The application was filed at the US Patent and Trademark Office, according to Apple Insider.
Apple describes a charging system that applies a rotational magnetic field to move an electric generator in a device. This results in electricity that could be stored in a battery cell and thus extend battery life on an Apple Watch or other devices.
The device might also use the same magnetic field to wind a spring
