Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional synchronizing mechanism is used in the hinge, then the left and right rotating brackets can rotate synchronously and reversely, but the thickness of the mobile terminal is increased
Solution Approach 1:
The patent repositions the intermediate gear from a vertical arrangement to a horizontal arrangement within the hinge structure. By changing the spatial orientation and dimension of gear placement, the mechanism achieves synchronous rotation functionality while reducing the thickness dimension of the overall hinge assembly, thus resolving the contradiction between reliability and thickness.
Solution Approach 2:
The hinge is divided into distinct functional modules: left rotating bracket, right rotating bracket, middle mounting frame, and intermediate gear. This segmentation allows each component to be optimized independently for its specific function while collectively achieving compact integration that reduces overall thickness while maintaining synchronous rotation reliability.
2Reliability
If a traditional synchronizing mechanism is used in the hinge, then the left and right rotating brackets can rotate synchronously and reversely, but the frame width is increased
Solution Approach 1:
The intermediate gear is repositioned to a horizontal arrangement within the hinge structure. By changing the spatial orientation and dimension of gear placement, the mechanism achieves synchronous rotation functionality while reducing the frame width dimension, thus resolving the contradiction between reliability and frame width.
3Length of stationary object
If the position of the intermediate gear is lowered, then the thickness and frame width are reduced, but the space for screen bending is limited
Solution Approach 1:
The hinge is divided into distinct functional modules: left rotating bracket, right rotating bracket, middle mounting frame, and intermediate gear. This segmentation allows each component to be optimized independently for its specific function while collectively achieving compact integration that reduces overall thickness while maintaining synchronous rotation reliability.
Solution Approach 2:
The intermediate gear is nested within the hinge structure at an optimized position that balances thickness reduction with adequate space for screen bending. The gear is positioned to utilize available space efficiently, creating a compact design that accommodates both the mechanical synchronization function and the physical requirements of flexible screen bending.
