Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the hinge component provides sufficient torque to prevent excessive rotation, then the display screen stability is improved, but the ease of operation deteriorates
Solution Approach 1:
The hinge device employs a dynamic torque control mechanism where the torque magnitude changes according to the rotation angle. The torsion control structure engages at different angles (first angle and second angle) to provide varying torque levels, allowing the display screen to be easily operated at small angles while maintaining stability at larger angles.
Solution Approach 2:
The invention changes the torque parameter dynamically based on the rotation angle. By designing the torsion control structure to engage at specific angles (first angle for initial positioning, second angle for stable support), the system adjusts the torque magnitude to match the operational needs at different stages of rotation.
2Stability of the object's composition
If the hinge component provides constant torque, then the display screen stability is improved, but the adaptability deteriorates
Solution Approach 1:
The hinge device transitions from static constant torque to dynamic variable torque based on rotation angle. The torsion control structure is designed to engage at different angles (first angle and second angle), providing appropriate torque levels for each operational stage, thereby adapting to different usage scenarios.
Solution Approach 2:
The torque parameter is changed dynamically according to the rotation angle. The system provides first torque at the first angle and second torque at the second angle, allowing the hinge to adapt to different operational requirements at different stages of display screen rotation.
3Ease of operation
If the hinge component allows free rotation, then the ease of operation is improved, but the stability deteriorates
Solution Approach 1:
The hinge device provides dynamic torque control where the torsion control structure engages at specific angles (first angle and second angle) to provide stability when needed, while allowing free rotation at other angles for ease of operation. This dynamic engagement prevents excessive rotation while maintaining operational flexibility.
Solution Approach 2:
The hinge device incorporates implicit feedback through the torsion control structure that senses the rotation angle and provides appropriate torque resistance. When the display screen reaches the first angle or second angle, the structure engages to provide stability, while allowing smoother rotation at intermediate angles for ease of operation.
