On January 12, according to Sina Digital, in a patent filed with the U.S. Patent and Trademark Office called "Product Display System", Apple detailed some mechanical systems used to protect the iPhone, iPad and Apple Watch.

While Apple's exhibits automatically go into lost mode after they are stolen and the device can't be used, the document suggests that anti-theft and robbery prevention is still an area of research the company is currently conducting.
The patent scheme mentions fixing a "retainer body" and a "display lever" on large tables in the Apple Store that have a "retainer bracket" to secure the device. Some devices may have retractable "fixed cables" that connect to the brackets for product charging and allow customers to pick up the device for the experience. A magnet placed on top of the display bar ensures that the device is retracted into its intended position.
To maintain safety and aesthetics, the device "may not be visible or reachable" during installation. The rods and brackets are much heavier than the safety ropes currently used in the Apple Store, with the aim of making it harder for thieves to disassemble devices or cut them short, thus stopping theft.
For aesthetics, Apple has tried to remove the safety rope, but the company has suffered a large number of smash robberies in recent years. At present, this solution does not seem to be technically difficult, and the possibility of practical use is very high. It has been used by some of Apple's authorized dealers.
