Solution Overview

Problem

Existing ground stabilisation and erosion prevention systems, such as gabions, suffer from premature structural failure, high maintenance costs, and environmental disruption due to their rigid design and susceptibility to external forces, making them costly and inefficient in challenging environments.

Innovation Solution

A ground stabilisation assembly using chain-link wire mesh cells that are tensioned and overlapped to form a flexible, self-tensioning structure, allowing for adjustable cell sizes and enhanced strength, with stainless steel wire mesh and optional brace assemblies for increased resilience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rigid gabion structures are used for ground stabilisation, then structural strength is improved, but susceptibility to movement by external forces increases

Engineering Contradiction:
Improvestructural strengthVSAvoidresistance to movement
Core Design Contradiction:
StrengthVSStability of the object's composition

Solution Approach 1:

The patent applies the dynamics principle by transitioning from rigid gabion structures to flexible netting that can dynamically adapt to external forces. The netting system allows controlled movement and deformation under wave action or ground movement, preventing structural failure while maintaining stabilisation function. This dynamic flexibility resolves the contradiction by enabling the structure to withstand forces without being displaced.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs flexible shells and thin films by using woven or knitted netting material instead of rigid gabion walls. The netting acts as a flexible membrane that can bend and deform under external loads, distributing forces across the entire structure rather than concentrating stress at specific points. This flexible approach maintains structural integrity while resisting movement from external forces.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of manufacture

If conventional gabion assembly methods are used, then ease of manufacture is improved, but installation time increases

Engineering Contradiction:
Improveease of assemblyVSAvoidinstallation time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent applies segmentation by dividing the ground stabilisation structure into modular panels of netting that can be manufactured separately and then quickly assembled on-site. Each panel can be prepared in advance with minimal processing, and the modular design allows for rapid deployment by simply connecting panels together, significantly reducing installation time while maintaining ease of manufacture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs preliminary action by pre-manufacturing and pre-assembling netting panels in a controlled environment before deployment. The panels can be prepared with appropriate dimensions, reinforcement, and connections in advance, allowing for rapid installation on-site without the need for complex assembly operations during the critical ground stabilisation work.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If rock armour is used for erosion prevention, then protection capability is improved, but environmental disruption increases

Engineering Contradiction:
Improveerosion protection capabilityVSAvoidenvironmental disruption
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses flexible netting structures that conform to the underlying terrain and provide erosion protection while maintaining natural drainage patterns. The permeable nature of the netting allows water to pass through, preventing the buildup of hydrostatic pressure and maintaining ecological processes, unlike impermeable rock armour that disrupts natural water flow and sediment transport.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent employs biodegradable or environmentally friendly materials for the netting structure that can naturally degrade over time as vegetation establishes itself. This approach provides temporary protection during the critical establishment period while eventually returning to the environment, contrasting with permanent rock armour that continuously disrupts ecological processes.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

A ground stabilisation system, a cell assembly and a kit of parts for such a system, and methods of making and installing such cell assemblies are disclosed. A cell assembly (1701) comprises a rock containment cell having a bottom, first and second sides, first and second ends and a top each formed from chain-link wire mesh, wherein a first continuous sheet of mesh (1710) wraps around and defines the upper, lower and end faces of the cell assembly and is joined end to end by an overlapping join. The first side face is defined by a continuous length of chain-link wire mesh that at least partially wraps around another adjacent face of the cell assembly, and the second side face of the cell assembly is defined by a continuous length of chain-link wire mesh that at least partially wraps around another adjacent face of the cell assembly. The mesh defining the first and second side faces may be a single continuous sheet (1720).
