Fence Element With Non-Vertical Transverse Tubes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fence elements, primarily composed of welded steel grids with upright oval cross-section tubes, face stability and load capacity issues under significant loads and transverse forces.
Innovation Solution
The fence element design is enhanced by arranging at least one transverse tube non-vertically, such as horizontally or obliquely, with the second and fifth tubes being particularly optimized in this configuration, and maintaining an oval or elongated cross-section, which improves stability and load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If all cross tubes are arranged upright (vertical orientation), then the fence element structure is simple and easy to manufacture, but the stability and load capacity under transverse loads is insufficient
Solution Approach 1:
The patent applies asymmetry by varying the orientation of cross tubes - while most cross tubes remain upright, at least one cross tube (preferably the second or fifth from the top) is arranged horizontally or obliquely. This asymmetric configuration creates a more stable structure that better resists transverse loads, while maintaining relatively simple manufacturing processes.
2Strength
If transverse tubes are arranged horizontally or obliquely instead of vertically, then the load capacity and stability improve, but the manufacturing and installation complexity increases
Solution Approach 1:
The patent applies local quality by implementing horizontal or oblique arrangement only for specific cross tubes (particularly the second or fifth from the top) rather than all cross tubes. This localized modification provides enhanced load capacity and stability at critical positions while keeping the majority of the structure simple and easy to manufacture.
3Object-affected harmful factors
If the cross tube orientation is varied (horizontal or oblique), then the disruptive influence on animals is reduced, but the device complexity increases
Solution Approach 1:
The asymmetric arrangement of at least one cross tube horizontally or obliquely creates a more natural, less uniform appearance that reduces disruptive influence on animals. This configuration better mimics natural vegetation patterns while maintaining relatively simple overall structure.
