Hinge Mechanism Prevents Screen Damage at Small Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices, such as laptops, are prone to damage due to their movement mechanisms, which can cause misalignment and scratches when the screen is rotated at small angles, leading to aesthetic and functional issues.
Innovation Solution
The electronic device employs a connection assembly with a first and second part, allowing independent movement in different modes (e.g., flipping and rotation) and an impact member that switches states to limit or allow movement based on position relationships, preventing unnecessary damage by ensuring the screen only rotates after a certain angle is reached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen is allowed to rotate freely at small angles, then the device has greater movement flexibility and versatility, but the screen may become misaligned and scratched causing damage
Solution Approach 1:
The connection assembly is designed with a predetermined rotation angle threshold that prevents the screen from rotating at small angles where misalignment and scratching occur. By establishing this protective constraint before normal rotation can begin, the harmful effects are prevented in advance while still allowing full versatility at acceptable angles.
Solution Approach 2:
The connection assembly acts as an intermediary mechanism between the screen and the device body. It mediates the rotation movement by allowing it only after a predetermined angle is reached, thereby protecting the screen from direct harmful effects of small-angle rotation while maintaining overall movement flexibility.
2Adaptability or versatility
If the connection assembly allows movement in multiple motion modes, then the device has enhanced functionality, but the complexity of the connection assembly increases
Solution Approach 1:
The connection assembly is designed as a multi-functional mechanism that integrates both flipping and rotation motion modes within a single structure. This universal design allows the device to achieve enhanced functionality without proportionally increasing complexity, as one assembly performs multiple movement functions.
Solution Approach 2:
The connection assembly is segmented into distinct functional parts: a first part configured for flipping motion and a second part configured for rotation motion. This segmentation allows each part to be optimized for its specific function while working together as an integrated system, managing complexity through modular functional division.

AI summary
An electronic device includes a first body, a second body, and a connection assembly. The connection assembly connects the first body and the second body and includes a first part and a second part. The first part is configured to allow the first body to move relative to the second body in a first motion mode. The second part is configured to allow the first body to move relative to the second body in a second motion mode. The first body moves in the first motion mode through the first part to a position satisfying a first position relationship with the second body. Movement of the first body in the second motion mode through the second part is impacted.
