A newly published patent from the United States Patent and Trademark Office reveals Samsung’s continued push into wearable AR and mixed-reality hardware. The filing, published under the number US 2025/0347929 A1, describes a next-generation augmented reality wearable electronic device with a specialised hinge and frame system designed to offer improved comfort, flexibility, and adaptability for different users. Filed by Samsung Electronics, the document outlines how the company aims to enhance ergonomics through a precision-engineered mechanism that adjusts more naturally to various head sizes before diving deeper into the technical design.
Adjustable hinge design for improved wearability
According to the patent, Samsung’s AR/VR smart glasses comprise three primary structural elements, a body portion, a glass-mounting section, and a pair of temple members. These are connected through a rotatable hinge structure crafted to improve flexibility when the glasses are worn. The hinge module consists of a hinge housing, a first shaft connected to the body, and a second shaft connected to the temple arm, allowing for controlled rotation between these segments. This arrangement helps the glasses adapt to different head widths without creating excessive pressure points, a common issue in extended AR or VR usage sessions.
The hinge system further incorporates a pulley-based mechanism, including a first pulley on the body portion and a second pulley on the temple section. A wire runs across these pulleys, enabling coordinated and smooth movement between both sides of the glasses. This mechanical synchronisation ensures that the frame expands or contracts uniformly, improving stability and maintaining correct alignment during use. The design aims to minimise slippage and enhance balance, especially during motion-heavy or gesture-based AR interactions.
Samsung’s documentation makes it clear that user comfort and durability are central to the concept. The adjustable hinge layout not only helps customise the fit but also supports repeated rotational movement without compromising structural rigidity. The pulley-wire system distributes mechanical stress more effectively, potentially extending the lifespan of the glasses while keeping the weight distribution even across the temples.
While the patent does not confirm a commercial product, the engineering focus suggests that Samsung is preparing hardware foundations for future AR/VR glasses that are lighter, more adaptable, and more comfortable for long-term use. This aligns with the broader trend of designing mixed-reality headsets that aim to feel more like traditional eyewear rather than bulky headgear.
