Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing soil stabilization systems using soil bags are prone to shifting and deterioration due to reliance on gravity and friction, and impervious plates that prevent water and plant growth, leading to structural instability and quick degradation, especially when using degradable materials.

Innovation Solution

An interwoven system of soil bags and geogrid weaver strips that facilitates water drainage and plant growth, using biodegradable materials and geogrid strips woven or twined between soil bags to enhance stability and strength, allowing for the use of degradable soil bags while supporting plant growth and water penetration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If impervious plates are used to hold soil bags in place, then soil bags are initially secured, but water and plant growth are blocked causing deterioration and structural instability

Engineering Contradiction:

Improvestability of soil bagsVSAvoidwater blockage and plant growth inhibition

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces impervious plates with porous permeable plates that allow water to pass through and enable plant roots to penetrate. This resolves the contradiction by maintaining the soil bag anchoring function while eliminating the harmful effects of water blockage and plant growth inhibition, allowing the structure to self-reinforce through vegetation.

Inventive Principle:

Principle #31Porous materials

2Adaptability or versatility

If degradable materials are used for soil bags, then environmental friendliness is improved, but structural strength decreases over time as material decomposes

Engineering Contradiction:

Improveuse of degradable materialsVSAvoidstructural strength of soil bags

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The patent employs degradable soil bags that decompose over time, with the degradation process serving a useful function: as the bags break down, they release nutrients and create space for plant roots to grow and take over the structural support role. The system self-reinforces through vegetation maturation, transforming the weakness of degradable material into a strength through ecological succession.

Inventive Principle:

Principle #25Self-service

3Device complexity

If gravity and friction alone are used to hold soil bags, then the system is simple, but soil bags shift and move over time causing structural instability

Engineering Contradiction:

Improvesimplicity of holding mechanismVSAvoidstability of soil bags

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent introduces permeable plates as intermediary elements between the soil bags and the ground. These plates provide mechanical anchoring through their structure while allowing water and roots to pass through, creating a more reliable connection than gravity and friction alone without significantly increasing system complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A soil stabilization system comprised of recent courses of soil bags woven and/or intertwined with geogrid and soil stabilization bodies pierce the soil stabilization bodies and protrusions on sides which protrude into the soil bags of the adjacent courses. Protrusions on the soil stabilization bodies shall protrude through holes in the geogrid to help anchor the soil bags relative to each other.
