The source found that the US Patent Office had granted Apple a patent for a new electronic device folding system that uses rollers and friction. The patent describes a possible future design for MacBooks and the Magic Keyboard for the iPad Pro.

The patent describes a “portable computing device” that may include a display portion and a base portion with an input device. These parts are interconnected by means of a hinge assembly. This assembly provides a closed position when the display is over the base part, and an open position when the parts are at an angle to each other. The hinge assembly includes one or more roller members. Additionally, spacers can be located between them. The assembly may additionally include a strap connected to the display housing and base portion and passing through the first roller element, the second roller element, and the spacer element.


Patent No. 11079807 is called “Friction Roller Hinge for Electronic Devices and a Method for Manufacturing Roller and Spacer Elements”. How soon the friction roller hinges will find their way into production Apple products is unknown.
