Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a locking and attaching type sliding rail with a lifting slider is used, then the support can be lifted and positioned, but the friction force is fixed and cannot be adjusted with use states
Solution Approach 1:
The patent transforms the static friction force into a dynamic one by introducing a spring component that automatically adjusts the pressing force between the slider and the sliding rail. The spring constant and pre-compression can be designed to provide appropriate friction force under different loading conditions, eliminating the need for fixed friction coefficients and locking mechanisms.
Solution Approach 2:
The patent changes the friction force parameter dynamically through the spring mechanism. By adjusting the spring pre-compression or selecting different spring constants, the friction force can be optimized for different use states and bearing weights, allowing the system to adapt without structural modification.
2Reliability
If locking screws are used to limit the sliding structure, then the position can be fixed, but the operation becomes more complex and time-consuming
Solution Approach 1:
The patent employs a self-locking mechanism where the spring-loaded slider automatically maintains contact with the sliding rail through elastic force. The friction generated by this contact provides inherent position stability without requiring external locking screws or additional fixing operations, thus simplifying the user操作流程.
Solution Approach 2:
The spring component acts as a counterbalancing element that continuously applies a pressing force to maintain slider-rail contact. This elastic counterforce ensures reliable position holding by compensating for gravitational and operational forces, eliminating the need for separate locking mechanisms.
3Ease of operation
If the main body directly contacts the guide rails, then the structure is simple, but the friction force is large and movement is not smooth
Solution Approach 1:
The patent introduces rollers as intermediary elements between the main body and the guide rails. These rollers convert direct sliding friction into rolling friction, significantly reducing the friction force and enabling smoother movement. The rollers are simple in design but effective in resolving the friction issue.
Solution Approach 2:
The patent replaces the sliding friction mechanism with a rolling friction mechanism by incorporating rollers. This substitution fundamentally changes the type of friction from sliding to rolling, dramatically reducing the resistance to movement while adding minimal structural complexity.

Implementation Method 1
a tension spring, one end of which is fixedly connected to the support body and located between the main body and the moving block for providing resistance for the main body
Implementation Method 2

AI summary
The present invention relates to the technical field of display supports, and specifically relates to a display support facilitating multi-directional adjustment and being telescopic, comprising a support body, a base, a lifting structure, a connecting structure, and a bearing member fixing structure, the base is arranged below the support body for fixing the support body, and the lifting structure is mounted on the support body for moving a bearing member up and down. The present invention may tilt up and down or swing left and right through rotating blocks and track correction blocks thereon, thereby enabling flat surfaces of rollers or side edges of a main body to be in direct contact with guide rails as little as possible and enabling curved surfaces of the rollers to be in contact with the guide rails as much as possible to increase friction forces during sliding.
