Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing fence technologies, such as stay knot and fixed knot fences, face challenges in maintaining structural integrity and animal welfare due to distortion by animals, which can lead to escape or entrapment, and lack the ability to customize knot types for specific applications.

Innovation Solution

A fence mesh system with multiple zones, each utilizing either fixed or stay knots, and a machine capable of producing these zones using a single set of drive shafts to form different types of wire knots, allowing for customization and enhanced resistance to distortion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If stay knots are used in fence mesh, then animal welfare is improved (no exposed wire ends or tight coils), but structural integrity deteriorates (animals can push knots along line wire, increasing mesh distortion)

Engineering Contradiction:

Improveanimal welfareVSAvoidmesh stability

Core Design Contradiction:

Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The fence mesh is divided into multiple zones with different knot types. The first zone uses stay knots for animal welfare, while the second zone uses fixed knots for structural stability. This segmentation allows each zone to perform its specific function optimally.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different knot types are applied to different zones of the fence mesh based on local requirements. The first zone (animal contact area) uses stay knots with no exposed ends, while the second zone (structural support area) uses fixed knots with exposed ends for greater stability.

Inventive Principle:

Principle #3Local quality

2Stability of the object's composition

If fixed knots are used in fence mesh, then structural integrity is improved (knots are more resistant to distortion), but animal welfare deteriorates (exposed wire ends and tight coils can damage animal hides)

Engineering Contradiction:

Improvemesh stabilityVSAvoidanimal welfare

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Inventive Principle:

Principle #3Local quality

3Ease of manufacture

If a single knot type is used throughout the fence mesh, then manufacturing simplicity is maintained, but adaptability deteriorates (cannot customize for different applications)

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidapplication customization

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The machine is designed to produce multiple knot types using a single set of drive shafts, allowing one machine to manufacture different fence mesh configurations for various applications, achieving multi-functionality.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If multiple knot types are produced using a single machine, then adaptability is improved (can customize for different applications), but device complexity increases

Engineering Contradiction:

Improveknot type customizationVSAvoidmachine complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The machine allows dynamic selection of knot types for different zones along the fence mesh production line, enabling flexibility in manufacturing different configurations without requiring multiple dedicated machines.

Inventive Principle:

Principle #15Dynamics

AI summary

Fence mesh including line wires, and stay wires extending laterally across and intersecting the line wires to form a mesh, wherein a first type of wire knot is formed by a knot wire around the line wire and stay wire at intersections of the stay wires with the line wires in a primary zone, and wherein a second type of wire knot is formed by a knot wire around the line wire and stay wire at intersections of the stay wires with the line wires in a secondary zone, characterised in that the first type of wire knot is different from the second type of wire knot; and a machine for the formation of such a mesh.
