Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical spring structure is used for height adjustment, then cost is reduced and life is extended, but height adjustment experience deteriorates due to reliance on friction for balance
Solution Approach 1:
The patent applies the dynamics principle by introducing a movable threaded sliding block that can be adjusted along the threaded rod to change the precompression amount of the mechanical spring. This dynamic adjustment capability allows the system to adapt to different display weights and achieve proper balance, transforming the static friction-dependent system into a dynamically adjustable one that provides smooth height adjustment experience comparable to air spring supports.
Solution Approach 2:
The patent implements parameter changes by allowing adjustment of the precompression amount of the mechanical spring through the threaded sliding block mechanism. By changing the precompression parameter, the system can optimize the elastic force to match different display weights, thereby improving the height adjustment experience while maintaining the reliability advantages of mechanical springs.
2Ease of manufacture
If a mechanical spring structure is used for height adjustment, then cost is reduced and environmental protection is improved, but height adjustment experience deteriorates due to reliance on friction for balance
Solution Approach 1:
The patent applies the dynamics principle by introducing a movable threaded sliding block that can be adjusted along the threaded rod to change the precompression amount of the mechanical spring. This dynamic adjustment capability allows the system to adapt to different display weights and achieve proper balance, transforming the static friction-dependent system into a dynamically adjustable one that provides smooth height adjustment experience comparable to air spring supports.
Solution Approach 2:
The patent implements parameter changes by allowing adjustment of the precompression amount of the mechanical spring through the threaded sliding block mechanism. By changing the precompression parameter, the system can optimize the elastic force to match different display weights, thereby improving the height adjustment experience while maintaining the cost advantages of mechanical springs.
3Adaptability or versatility
If the precompression amount of the mechanical spring is increased to adapt to heavier displays, then weight adaptability is improved, but the ability to stop at different heights deteriorates due to excessive elastic force
Solution Approach 1:
The patent applies the dynamics principle by making the precompression amount adjustable through the threaded sliding block mechanism. This allows the system to dynamically adapt to different display weights while maintaining the ability to stop at different heights. The adjustability ensures that the elastic force is optimized for each specific weight, preventing both insufficient support for heavy displays and excessive force that would prevent free stopping.
Solution Approach 2:
The patent implements parameter changes by allowing adjustment of the precompression amount to match different display weights. This parameter optimization ensures that the mechanical spring provides appropriate elastic force for each weight scenario, achieving both weight adaptability and free stop capability without the trade-off present in fixed precompression designs.

AI summary
A display support having freely adjustable height, including a base (1) and a connector (4) for installing a display, wherein an upper connecting arm (2) and a lower connecting arm (3), which are parallel to each other, are arranged between the base (1) and the connector (4). The display support further includes a mechanical spring (6), wherein an end of the mechanical spring (6) is hinged with the connector (4) or the lower connecting arm (3), the other end of the mechanical spring (6) is hinged with a threaded sliding block (7), the threaded sliding block (7) sleeves on a threaded rod (8), the threaded rod (8) is arranged in the base (1), so that when an end part of the threaded rod (8) is operated to drive the threaded rod (8) to rotate, the threaded sliding block (7) moves along the threaded rod (8), and a position of the threaded sliding block (7) on the threaded rod (8) can be adjusted according to the weight of the display on the connector (4), so that when the connector (4) is moved upwards or downwards, the connector (4) can be stopped at different heights relative to the base (1). The display support having freely adjustable height can realize free stop of height adjustment, and thus is better than an air spring support.
