Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional hinge structure is used, then the device structure is simple, but it cannot provide sufficient support space for flexible screen bending
Solution Approach 1:
The hinge is divided into multiple supporting plates (first, second, third supporting plates) connected through rotation joints, creating a segmented multi-link mechanism that provides sufficient bending space while maintaining structural manageability
Solution Approach 2:
The hinge structure serves dual functions: it acts as both the hinge mechanism enabling folding and as the supporting structure for the flexible screen, eliminating the need for separate support components and reducing overall device complexity
2Ease of operation
If the flexible screen is laid on the inside of the hinge, then the screen can bend freely, but the supporting structure becomes complex
Solution Approach 1:
The hinge structure serves dual functions: it acts as both the hinge mechanism enabling folding and as the supporting structure for the flexible screen, eliminating the need for separate support components and reducing overall device complexity
Solution Approach 2:
The supporting plates are designed to rotate relative to each other, dynamically adjusting the support geometry to accommodate the flexible screen's bending motion while maintaining structural integrity

AI summary
A hinge for a mobile terminal having an inwardly bendable flexible screen comprises: a three-member mechanism consisting of a left supporting plate, a middle supporting plate and a right supporting plate which are rotatably and sequentially connected; a left supporting frame; a right supporting frame; and a middle U-shaped outer cover. Both ends of the three-member mechanism are free ends, such that the left supporting plate, the middle supporting plate and the right supporting plate are flexible screen supporting members capable of moving up and down. After moving up, the left supporting plate, the middle supporting plate and the right supporting plate form a flexible screen supporting face, and after moving down, the components are in a bent state, thereby providing a space for bending of the flexible screen. After moving down, the middle supporting plate reaches a bottom portion of the middle U-shaped outer cover. The present invention can provide a larger space for bending of the flexible screen such that the middle mechanism of the hinge is not exposed after folded, and it can be used in mobile terminals such as mobile phones, e-books, and computers, enabling the mobile terminal to achieve large-screen display in a small volume.
