Solution Overview

Problem

Existing edge finishing methods for wire mesh, such as twisting and single knuckle arrangements, are either unsafe or insufficiently strong, particularly in aquaculture applications where mesh cages need to maintain integrity and safety, and manual formation leads to labor-intensive, costly, and irregular results with potential distortion and shortening of the mesh edge.

Innovation Solution

A double interlocked loop edge finishing method where two loops are formed at the terminal ends of adjacent pickets, interlocked at their intersection, providing greater resistance, safety, and stability, and can be machine-formed to ensure consistency and minimize edge shortening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If twisted finishing is used to maintain mesh integrity, then strength is improved, but safety deteriorates due to sharp rigid ends

Engineering Contradiction:
Improvemesh integrityVSAvoidsafety hazard
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The picket tails are formed into loops with curved geometry instead of sharp twisted ends. The loop configuration eliminates sharp protrusions while maintaining structural strength through the curved form factor, directly resolving the safety hazard while preserving mesh integrity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The potentially harmful sharp picket tails are transformed into beneficial loop structures. The same wire material that creates sharp dangerous ends when twisted is instead formed into safe loops that maintain strength, converting the harmful sharpness into a beneficial safety feature.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Object-affected harmful factors

If single knuckle finishing is used to improve safety, then safety is improved, but strength deteriorates as joints can be pulled apart

Engineering Contradiction:
ImprovesafetyVSAvoidjoint strength
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

Two knuckles are merged into a single integrated loop structure where the first and second knuckles work together to form a unified loop. This combination provides both the safety of rounded edges and the strength of multiple attachment points, as the loop configuration distributes loads across both knuckle formations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The first knuckle and second knuckle are nested within the same loop structure, with each knuckle contributing to the overall loop formation. This nesting allows both knuckles to reinforce each other, providing enhanced strength while maintaining the safe loop geometry.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Object-affected harmful factors

If manual double knuckle formation is used to improve safety and strength, then both safety and strength are improved, but manufacturing complexity increases leading to labor-intensive production

Engineering Contradiction:
ImprovesafetyVSAvoidmanufacturing complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The picket tails are pre-formed into loop configurations during the mesh manufacturing process using automated forming mechanisms. By preparing the loop structures in advance during production rather than requiring manual assembly later, the complexity of double knuckle formation is reduced while maintaining safety and strength benefits.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The loop formation process is designed to be self-forming through the wire manipulation process, where the wire itself creates the loop structure through controlled bending and positioning. This self-service approach eliminates the need for complex manual operations or additional assembly steps, reducing manufacturing complexity while achieving the desired safety and strength outcomes.

Inventive Principle:
Principle #25Self-service

4Manufacturing precision

If manual double knuckle formation is used to achieve proper finishing, then quality is improved, but productivity deteriorates due to increased labor time

Engineering Contradiction:
Improvefinishing qualityVSAvoidproduction speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

Manual mechanical operations for forming double knuckles are replaced with automated wire forming mechanisms. The automated system uses controlled bending, rolling, or shaping devices to create the loop structures, maintaining consistent quality while dramatically increasing production speed and eliminating labor-intensive processes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The forming process parameters such as wire temperature, forming speed, and bending radius are optimized to enable high-speed automated loop formation. By adjusting these parameters, the system achieves both high production rates and consistent finishing quality, resolving the contradiction between productivity and manufacturing precision.

Inventive Principle:
Principle #35Parameter changes

5Manufacturing precision

If manual double knuckle formation is used to create proper loops, then loop formation is improved, but time consumption increases significantly

Engineering Contradiction:
Improveloop formation qualityVSAvoidproduction time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The loop formation process is integrated into the continuous mesh manufacturing workflow, eliminating interruptions and discrete manual steps. Wire loops are formed continuously as the mesh is produced, with automated forming devices operating without interruption to maintain both high quality loop formation and rapid production rates, significantly reducing time consumption.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

An edge finishing for a mesh formed by interlacing adjacent wire pickets, each picket formed in a zig-zag manner, the edge finishing comprising two interlinked loops where a first loop is formed from a first picket of the adjacent pickets and a second loop is formed from a second picket of the adjacent pickets, wherein the first loop and the second loop are interlocked together, via first and second loop-ends, at an intersection of the first picket and the second picket.
