Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a torsional spring is used in the hinge element to provide rebounding torque, then the display can be kept at a watching angle, but the structure becomes too complicated and production cost increases when trying to fit different display specifications
Solution Approach 1:
The patent extracts the torsional spring from the hinge element and replaces it with a separate elastic plate structure. The elastic plate is positioned between the support plate and the cam, providing the necessary elastic force without being integrated into the hinge element itself. This separation simplifies the hinge element structure while maintaining the display angle stability function.
Solution Approach 2:
The patent uses parameter changes by varying the elastic coefficient of the elastic plate to adapt to different display weights. Instead of redesigning the entire hinge element structure for different specifications, the system maintains a universal hinge element while changing only the elastic plate's parameters (elastic coefficient, dimensions) to suit different display weights, thereby reducing structural complexity and production cost.
2Adaptability or versatility
If an adjustable rebounding torque hinge element is used to fit different display specifications, then various display weights can be supported, but manufacturing and operation become difficult and production cost increases
Solution Approach 1:
The patent creates a universal hinge element structure that can support different display specifications through a standardized design. The hinge element remains consistent across different applications, while the elastic plate parameters are adjusted to accommodate various display weights. This universality simplifies manufacturing processes and reduces production costs by eliminating the need for multiple specialized hinge element designs.
Solution Approach 2:
The patent segments the hinge system into distinct functional components: a universal hinge element and replaceable elastic plates with different parameters. This segmentation allows the hinge element to be manufactured once and reused across different display specifications, while only the elastic plates need to be varied. This approach significantly reduces manufacturing complexity and inventory requirements.
3Reliability
If a torsional spring is used to provide rebounding torque, then balance can be maintained, but the structure is not suitable for light-weight and thickness requirements
Solution Approach 1:
The patent replaces the traditional torsional spring with a simpler elastic plate structure that is lighter in weight. The elastic plate, while providing the necessary balance function, has a reduced mass compared to a torsional spring mechanism, making it suitable for applications where weight and thickness are critical constraints. The elastic plate can be easily replaced if needed, further reducing the overall system weight.
4Reliability
If a torsional spring is used in the hinge element, then rebounding torque can be provided, but assembly and production cost increase
Solution Approach 1:
The patent extracts the elastic function from the hinge element and implements it through a separate elastic plate positioned between the support plate and the cam. This extraction simplifies the hinge element's assembly process, as it no longer requires integrating a torsional spring mechanism. The elastic plate can be easily installed and replaced, significantly reducing assembly time and production costs while maintaining the rebounding torque function.

AI summary
A hinge device for supporting a display device is provided. The hinge device comprises a supporting seat, a shaft, a bearing plate, and an elastic module. The shaft rotatably passes through the supporting seat. The bearing plate is disposed on the shaft, and the display device is disposed on the bearing plate. The elastic module includes a cam and at least one elastic plate. The cam is configured on the shaft, and the cam and the shaft rotate synchronously. A fixed end of the elastic plate is fixed to the supporting seat. The elastic plate has a deformation amount to provide a balance torque to the cam when a free end of the elastic plate abuts against the cam. When an external force is applied on the display device, the bearing plate is actuated to drive the shaft and the cam to rotate to change the deformation amount and the balance torque of the elastic plate. When the external force is removed, the display device can be stopped at once.
