Solution Overview

Problem

Existing containment gabions for inert materials lack stability during loading, unloading, and transport, and are prone to deformation or warping due to unstable ground support, which complicates assembly and stacking for forming retaining walls.

Innovation Solution

The gabion features specifically designed hooks at the ends of vertical rods for secure fixation to the support base, including U-shaped and J-shaped hooks that provide enhanced structural stability and facilitate easy stacking, using a metal mesh structure with zinc-aluminum alloy rods for corrosion resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If simple jointing methods (bending rods to anchor to adjacent walls) are used to connect vertical walls to the support base, then the structure is simple to manufacture, but the stability during loading, unloading and transport is inadequate

Engineering Contradiction:
Improveease of manufactureVSAvoidstability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The connection system is segmented into multiple functional components: hooks with specific geometries (J-shaped, U-shaped, L-shaped) that engage with corresponding elements (horizontal rods, vertical rods) at different locations. This segmentation allows each component to perform a specific stabilizing function while maintaining manufacturing simplicity through standardized metal mesh construction with integrated bends.

Inventive Principle:
Principle #1Segmentation

2Strength

If Z-shaped hooks encircling two horizontal rods are used to connect vertical walls to the support base, then the structural strength is improved, but the stability during unloading and assembly is not achieved and stacking becomes difficult

Engineering Contradiction:
Improvestructural strengthVSAvoidease of stacking
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

Different hook geometries are applied at different locations based on local requirements: J-shaped hooks at corners provide strong anchoring, U-shaped hooks along edges facilitate alignment, and L-shaped hooks at specific positions enable stacking. This localized optimization maintains high structural strength where needed while enabling ease of stacking at critical interface points.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The connection system operates in multiple spatial dimensions: hooks extend vertically from the support base, engage horizontal rods in the horizontal plane, and create vertical stacking interfaces. This multi-dimensional engagement provides both structural strength through multi-point anchoring and stacking capability through vertically-oriented connection geometries.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If conventional connection methods are used, then the gabion can be assembled, but it is prone to deformation or warping due to unstable ground support

Engineering Contradiction:
Improveease of assemblyVSAvoidstructural stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The hooks are pre-formed with specific geometries (J-shaped, U-shaped, L-shaped) during manufacturing, creating built-in alignment and stabilization features that automatically engage with corresponding elements during assembly. This preliminary preparation ensures proper geometric relationships are established before the gabion is subjected to ground support conditions, preventing deformation.

Principle #10Preliminary action

AI summary

A containment gabion for containment and transport of inert material comprises a base plate (2) and side walls, in the form of wire meshes composed of horizontal and vertical rods in crisscrossed arrangement, wherein at least one vertical wall (3) at its end is connected to the base plate (2) of the containment gabion (1), by first hooks, which are designed to impart structural stability and resistance to vertical stresses caused by the weight of the material, during unloading, loading and transport of the gabion.
