Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a gas spring is used as the force storage mechanism in the elastic support assembly, then the support force can be provided, but the structure becomes complex and costly due to the need for angle adjustment mechanisms to adapt to different display weights
Solution Approach 1:
The patent extracts the angle adjustment mechanism from the gas spring assembly, separating the force provision function (gas spring) from the angle adjustment function (independent adjustment mechanism). This allows the gas spring to maintain constant elastic force while the display support adapts to different weights through angle adjustment, resolving the contradiction between providing support force and maintaining structural simplicity.
Solution Approach 2:
The patent introduces a dynamic angle adjustment mechanism that allows the elastic support assembly to adapt its angle relative to the display support. This dynamic adjustment enables the system to accommodate different display weights while maintaining the gas spring's constant force characteristic, eliminating the need for complex built-in adjustment mechanisms within the gas spring itself.
2Adaptability or versatility
If the force arm included angle of the gas spring is adjusted to adapt to displays with different weights, then adaptability is improved, but the structure is complicated by requiring an angle adjustment mechanism
Solution Approach 1:
The patent segments the display support system into distinct functional modules: the gas spring assembly for force provision and an independent angle adjustment mechanism for adaptability. This segmentation allows each component to perform its specific function without requiring complex integration, reducing overall structural complexity while maintaining adaptability to different display weights.
Solution Approach 2:
The patent introduces an intermediary angle adjustment mechanism that mediates between the constant force output of the gas spring and the variable weight requirements of different displays. This intermediary component translates the constant force into adaptable support by adjusting the angle, eliminating the need for the gas spring itself to have complex adjustment capabilities.
3Force
If the elastic support assembly is arranged within the four-bar linkage to provide support and fix adjustment angle, then support function is improved, but the supporting arm becomes bulky and heavy
Solution Approach 1:
The patent nests the gas spring assembly within the existing four-bar linkage structure, utilizing the available space efficiently. The gas spring is positioned within the linkage geometry rather than adding external components, which minimizes the increase in overall structure size and weight while maintaining the support function.
Solution Approach 2:
The patent makes the four-bar linkage serve multiple functions: it provides the structural framework for the display support, enables angle adjustment, and houses the elastic support assembly. By making the linkage multi-functional, the patent eliminates the need for separate dedicated support structures, reducing overall weight and bulk while maintaining support capability.

AI summary
Disclosed is a spring adjustment supporting arm for a display support. The supporting arm comprises an upright column, a big supporting arm, a medium supporting arm and a supporting arm brace rod. The upright column, the big supporting arm, the medium supporting arm and the supporting arm brace rod are hinged to form a four-bar linkage. The big supporting arm is internally provided with a cavity, and the cavity is internally provided with a spring assembly. It is not necessary to adapt to the weight of a display by means of adjusting a force arm included angle of the spring assembly, and therefore, it is not necessary to arrange a force arm included angle adjustment mechanism, thus simplifying a mechanism of the supporting arm, improving the reliability of production and mounting, reducing production costs, prolonging the service life of a product and preventing potential safety hazards.
