Laptop PC Hinge

A laptop PC hinge featuring a one-hand open function that allows the display enclosure to be opened easily with one hand.

Users can freely adjust the display angle and maintain a comfortable viewing angle and working posture. The hinge securely holds the display position and enables the laptop PC to fold compactly for convenient portability and storage.

The integrated one-hand open mechanism allows the laptop PC to be opened even when only one hand is available.

Challenges, Solutions, and Results

Challenges

When opening a foldable notebook PC, the keyboard lifts together with the display enclosure, making one-hand opening difficult.
Reducing hinge rotational torque enables easier one-hand opening, but causes “gapping,” resulting in reduced product quality and perceived rigidity.

Solutions

Developed a proprietary mechanism that varies hinge rotational torque (holding force) depending on the notebook PC opening angle.

Results

Enables smooth one-hand opening of the notebook PC through the proprietary mechanism.
Supports lightweight notebook designs and touch panel operation.
