Knotted Mesh Fence With Integrated Barbed Top Wire
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mesh fences require additional labor to install separate runs of barbed wire for security, which lack rigidity and support due to not being connected to the rest of the fence.
Innovation Solution
Integrating barbed wire as the uppermost line wire in a mesh fence, secured with knots at intersections with stay wires, creating a strong and stock-resistant fence without the need for separate installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate barbed wire is installed alongside the mesh fence, then security is improved, but labor complexity and installation time increase significantly
Solution Approach 1:
The patent combines the barbed wire security function with the mesh fence structure by integrating barbed wire into the horizontal line wires of the mesh fence. This merging eliminates the need for separate barbed wire installation while maintaining security functionality, directly resolving the contradiction between improved security and reduced installation complexity
2Reliability
If separate barbed wire is installed alongside the mesh fence, then security is improved, but the additional labor and time required worsen productivity
Solution Approach 1:
By merging the barbed wire security function into the mesh fence's horizontal line wires, the patent enables single-pass installation where both fencing and security functions are achieved simultaneously. This eliminates the need for separate barbed wire handling, coiling, and attachment operations, thereby significantly improving installation productivity while maintaining security
3Reliability
If barbed wire is made bulky with multiple wires and barbs, then security function is improved, but handling and machine processing become significantly more difficult
Solution Approach 1:
The patent applies barbed wire characteristics locally only to the horizontal line wires of the mesh fence where security is needed, rather than making the entire fence structure bulky. The barbed wire is used in its standard form with barbs and twisted construction, maintaining its security function while avoiding the need to handle excessively bulky materials during installation
4Reliability
If barbed wire protrusions are added for security, then security function is improved, but the wire becomes more difficult to handle and tends to snag on adjacent parts
Solution Approach 1:
The patent merges the barbed wire into the horizontal line wires of the mesh fence structure, where the barbed wire is tensioned and supported by the vertical stay wires and horizontal line wire configuration. This integration reduces snagging issues compared to loose separate barbed wire, while the barbed wire's security function is maintained through its position within the fence structure

AI summary
A mesh fence which includes a series of spaced vertical stay wires crossed by a series of spaced horizontal line wires, with at least some of the intersections of the stay wires and line wires secured by a knot, in which at least one of the line wires is made of barbed wire.
