Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a highly elastic spring is installed on a shaft to adjust the angle of the LCD monitor using elastic force, then the angle adjustment function is achieved, but torque adjustment becomes difficult and frictional force reduces over time
Solution Approach 1:
The patent changes the physical state and parameters of the spring element by transforming it from a conventional coil spring to a disc spring configuration. This parameter change enables the spring to generate consistent torque over time and allows for adjustable torque levels, resolving the issue of difficult torque adjustment and frictional force reduction while maintaining smooth angle adjustment operation
2Ease of operation
If a plurality of circular special disc plates are installed to overlap each other and pressed in the axial direction to adjust the angle using frictional force, then angle adjustment is achieved, but frictional force reduces over time and torque adjustment becomes difficult
Solution Approach 1:
The patent transforms the friction-based adjustment mechanism into a spring-based torque mechanism by changing the physical parameters of the elastic element. The disc spring configuration provides stable, time-invariant torque generation, eliminating the frictional force degradation problem while maintaining ease of angle adjustment operation
3Device complexity
If an improper rotation angle between the LCD monitor and support is used, then the hinge structure can be simplified, but unnecessary space is required for packaging, increasing manufacturing costs
Solution Approach 1:
The patent optimizes the rotation angle parameters of the hinge structure to achieve a compact configuration that reduces packaging volume. By carefully selecting and adjusting the rotation angle parameters, the design achieves both structural simplification and space efficiency, eliminating the need for excessive packaging space while maintaining the required hinge functionality
