Apple Patents New Hinge Design for Foldable Devices

Apple continues to explore the design of foldable devices, as evidenced by the latest patent issued today, titled “Hinges for folding display devices” (US 12,164,344). Over the years, Apple has received numerous patents related to foldable technology, but the company has not yet produced such a device, with delays reportedly hindering its progress.

The newly issued patent details a hinge mechanism featuring interconnected links formed by interlinked “fingers” and a friction clutch. A notable innovation in this design is the use of crescent-shaped slots that allow each link to rotate relative to others. This arrangement moves the axis of rotation outside of the link itself, addressing key challenges in hinge functionality.

The patent states that this hinge design can apply broadly across various devices, such as phones, tablets, laptops, watches, and other wearables. While this indicates Apple’s intent to cover multiple possibilities, it remains unclear whether this hinge represents an improved version of previous designs or if it will coexist with other patented hinge systems for different devices.

The patent further describes how the fingers, pins, and gears interact to create a compact yet effective clutch mechanism. This system offers precise friction control, enabling the hinge to maintain the desired folding angle. The gears ensure that both sides of the hinge rotate equally, ensuring a seamless folding and unfolding process.

Reports have suggested that Apple is working on a flip-style iPhone and larger foldable devices, such as an iPad or MacBook. The company faces “technical challenges,” as noted by analyst Ming-Chi Kuo, particularly in developing reliable display and hinge mechanisms. Whether this patent will address those challenges remains to be seen, but it highlights Apple’s ongoing efforts in the foldable technology space.
