Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed lifting power components (gas springs or tension springs) are used, then the lifting desk can operate automatically within a fixed load range, but the lifting power cannot be adjusted when the load changes, leading to unstable or laborious lifting
Solution Approach 1:
The patent applies the dynamics principle by making the lifting power adjustable rather than fixed. The tension spring's initial tension can be modified, and the fixed end's position can be adjusted along the desk support, allowing the system to adapt dynamically to different load conditions. This transforms a static system into a dynamic one that can respond to varying requirements.
Solution Approach 2:
The patent implements parameter changes by allowing modification of the tension spring's initial tension parameter and the position parameter of the fixed end. These parameter adjustments enable the lifting desk to adapt to different load ranges without changing the fundamental structure, resolving the contradiction between adaptability and complexity.
2Reliability
If gas springs are used as power components, then the lifting desk rises uniformly within a designed load range, but when the load exceeds the design range, the lifting desk rises insufficiently and requires manual lifting
Solution Approach 1:
The patent converts the static gas spring system into a dynamic tension spring system where the initial tension and fixed end position can be adjusted. This allows the lifting force to be adapted to different load ranges while maintaining reliable and stable lifting performance across varying conditions.
Solution Approach 2:
By allowing adjustment of the tension spring's initial tension and the fixed end's position parameter, the system can maintain reliable lifting performance across different load ranges, eliminating the limitation of fixed load range adaptability.
3Speed
If tension springs are used as power components, then the lifting desk rises automatically and quickly, but when the desk load is too heavy, the desk needs to be raised manually, degrading user experience
Solution Approach 1:
The patent allows adjustment of the tension spring's initial tension parameter and the fixed end position, enabling the system to maintain quick automatic lifting speed while adapting to heavier loads. This resolves the contradiction by making the lifting parameters adjustable rather than fixed.
4Adaptability or versatility
If existing lifting desks are replaced with new lifting desks, then the new desks can provide adjustable lifting power, but this replacement process wastes time and manpower and causes cost waste
Solution Approach 1:
The patent transforms existing fixed lifting desk structures into adjustable ones by adding adjustment mechanisms for the tension spring's initial tension and fixed end position. This allows existing desks to be upgraded with adaptable lifting power without complete replacement, saving time and resources.
Solution Approach 2:
The patent makes the lifting desk structure universal by adding adjustable parameters that can accommodate different load requirements. This multi-functionality allows a single desk design to serve multiple load conditions, eliminating the need for replacement.

AI summary
Disclosed is a lifting desk, comprising a desk support (2), a desk top (1) arranged above the desk support (2), and two X-shaped lifting supports (3) arranged on two sides of the desk support (2). Each of the X-shaped lifting supports (3) comprises a first supporting portion (31) and a second supporting portion (32). A tension spring (7) is arranged between an upper end of the first supporting portion (31) and an upper end of the second supporting portion (32), wherein a movable end of the tension spring (7) is connected to the upper end of the first supporting portion (31), and a fixed end of the tension spring (7) is fixed to the desk support (2) via a distance-adjusting device. The distance between the fixed end of the tension spring (7) and the desk support (2) is adjusted using the distance-adjusting device, and the pull force stroke length of the tension spring (7) is changed, so that the pull force of the tension spring (7) is adapted to a load, thereby making the lifting process of the lifting desk stable and reducing the effort needed therefor, and improving the user experience.
