Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional tension boards for net style fencing materials are inefficient in simultaneously tensioning and joining multiple rolls of fencing material, often causing uneven tension and requiring complex clamping mechanisms.
Innovation Solution
A tension board with wire grippers, comprising a parallelogram arrangement of distal and proximal arms with a spring mechanism, allows for easy grasping and tensioning of horizontal wires, enabling simultaneous tensioning of multiple rolls with adjustable spacing and easy application/release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wooden or steel tension boards with clamping mechanisms are used, then the net material can be tensioned, but the operation becomes complex and time-consuming with uneven tension distribution
Solution Approach 1:
The tension board is segmented into multiple independent wire grippers (at least three) distributed along its length, each capable of independently grasping horizontal wires at different positions. This segmentation allows simultaneous tensioning of multiple wires without requiring a complex overall clamping mechanism, simplifying the device while improving operational ease and tension uniformity.
Solution Approach 2:
Each wire gripper is equipped with a spring mechanism that automatically engages with the horizontal wires when the tension board is inserted. The springs provide automatic wire engagement and maintain constant tension pressure without requiring manual adjustment or complex control systems, making the device self-servicing and operationally simple.
2Productivity
If traditional tension boards clamp the entire net material, then tensioning is achieved, but the process is inefficient for simultaneously tensioning multiple rolls and adjusting fencing heights
Solution Approach 1:
The tension board incorporates multiple wire grippers positioned at different locations along its length, allowing simultaneous engagement with horizontal wires from multiple rolls of net material. This enables parallel tensioning operations, significantly improving productivity when installing exclusion fencing with multiple rolls, while the modular design allows quick adjustment for different fencing heights.
Solution Approach 2:
The tension board is designed as a universal device that can tension net material of varying heights (from traditional waist-high to 2-meter exclusion fencing) by simply adjusting which wire grippers engage with which horizontal wires. This multi-functionality eliminates the need for different tensioning devices for different fencing types, reducing installation time and increasing productivity across various applications.
3Manufacturing precision
If traditional tension boards are used for exclusion fencing with 2-meter height, then the fencing can be installed, but the tension distribution becomes uneven across the large vertical distance
Solution Approach 1:
The tension board divides the long vertical span of exclusion fencing into multiple shorter tensioning segments by incorporating at least three wire grippers positioned at different vertical locations. Each gripper independently tensions a specific horizontal wire, ensuring uniform tension distribution across the entire 2-meter height, preventing the uneven tension that would occur with a single clamping point.
Solution Approach 2:
Different wire grippers are positioned to engage with specific horizontal wires at different vertical locations along the net material. This local engagement ensures that each section of the tall fencing receives appropriate localized tension, creating uniform overall tension distribution across the entire vertical span of exclusion fencing, rather than applying tension at a single remote location.

AI summary
A tension board (30, 130) for straining net style fencing materials (42) composed of a first plurality of spaced apart substantially horizontal wires and a second plurality of spaced apart substantially vertical wires, is disclosed. The tension board takes the form of an elongate member having a longitudinal axis and a longitudinal extent at least corresponding to the distance between the first and last of the horizontal wires, and a plurality of wire grippers (10) connected to the elongate member at spaced apart locations. Each of the wire grippers (10) is configured to releasably grasp a corresponding one of the horizontal wires. This enables quick set up prior to straining and quick release once strained and tied off.
