Hinge Structure with Locking Mechanism for Easy Screen Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computer hinges require significant force to open and close the screen, necessitating users to hold both the computer host and screen simultaneously, making it cumbersome to adjust the screen to desired angles.
Innovation Solution
A hinge structure comprising a first fixing base, a second fixing base, a rotating element, and a control element, where the rotating element engages with the second fixing base to retain the screen at a desired angle, allowing users to easily open and close the device by pressing a control element to release the engagement mechanism and then releasing it to lock the angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a torque hinge is used to enable the screen to be retained at a required angle, then the screen can be kept at a stable angle, but significant force is required to open or close the screen
Solution Approach 1:
The hinge system is divided into two independent functional modules: a torque hinge module for angle retention and a locking mechanism module for position fixation. The locking mechanism includes a locking block that can engage with a locking groove to hold the screen at various angles without requiring continuous force, while the torque hinge separately provides the stability to maintain desired angles. This segmentation allows the screen to be both stable and easy to open/close.
2Stability of the object's composition
If a torque hinge is used to retain the screen at a required angle, then the screen position can be maintained, but the user must hold both the computer host and screen simultaneously to open the screen
Solution Approach 1:
The locking mechanism is designed to be engaged or disengaged in advance before the screen opening/closing operation. When the locking block is disengaged from the locking groove, the screen can be opened or closed without requiring the user to hold both parts simultaneously. The preliminary disengagement of the locking mechanism prepares the system for easy operation, while the torque hinge maintains position stability during use.
3Reliability
If the rotating element engages with the second fixing base to retain the screen at a desired angle, then the screen can be securely positioned, but the engagement mechanism must be released to allow rotation
Solution Approach 1:
The locking mechanism is designed to automatically engage and disengage without requiring complex external control. The locking block automatically engages with the locking groove when the screen reaches a desired angle, providing secure positioning. To release, the user simply needs to press the elastic element, which automatically disengages the locking block from the locking groove, allowing rotation. This self-service design maintains reliability while minimizing operational complexity.

AI summary
A hinge structure for an electronic device including a first part and a second part is provided. The hinge structure includes a first fixing base, a second fixing base, a rotating element, and a control element. The first fixing base connects to the first part. The second fixing base connects to the second part and includes a first locking structure. The rotating element includes a second locking structure. An end of the rotating element rotatably and movably connects to the first fixing base along an axial direction. The other end of the rotating element engages with the first locking structure through the second locking structure. The control element extends to the rotating element for driving the rotating element to move along the axial direction.
