Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current erosion control rolls suffer from high turbidity runoff, lack of fire resistance, and short lifespan due to the use of dry, combustible materials.

Innovation Solution

An erosion control roll with a porous outer casing filled with mineral wool, providing flexibility, sediment separation, water flow diversion, and fire resistance, made by filling a tubular netting with mineral wool granules, which can be positioned to reduce sediment entry into drains and offer extended use life.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If dry material (straw, shaved wood, coconut fiber) is used to fill erosion control rolls, then the rolls are flexible and easy to install, but the material breaks down quickly and offers no fire resistance

Engineering Contradiction:

Improveease of installationVSAvoiduse life

Core Design Contradiction:

Ease of manufactureVSDuration of action of stationary object

Solution Approach 1:

The patent changes the material parameter from organic dry material to mineral wool, which fundamentally alters the durability and fire resistance properties while maintaining the erosion control function. This parameter change resolves the contradiction by selecting a material that inherently possesses both long-term stability and fire resistance.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses composite construction combining mineral wool fill material within a tube netting casing. This composite structure integrates the erosion control function with enhanced durability and fire resistance, resolving the contradiction between ease of installation and extended use life.

Inventive Principle:

Principle #40Composite materials

2Ease of manufacture

If dry material (straw, shaved wood, coconut fiber) is used to fill erosion control rolls, then the rolls are simple and inexpensive to manufacture, but the material provides no fire resistance

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidfire resistance

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from combustible organic material to non-combustible mineral wool, directly addressing the fire resistance requirement while maintaining manufacturing simplicity through the use of readily available mineral wool granules.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent converts the potential harm of using combustible materials into a benefit by selecting mineral wool, which is inherently fire-resistant. This transforms the fire risk associated with traditional erosion control materials into a safety advantage.

Inventive Principle:

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

3Use of energy by moving object

If dry material (straw, shaved wood, coconut fiber) is used to fill erosion control rolls, then the rolls allow water flow, but the material produces high turbidity runoff

Engineering Contradiction:

Improvewater flowVSAvoidturbidity runoff

Core Design Contradiction:

Use of energy by moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent employs porous tube netting casing that allows water flow while the mineral wool fill material filters sediment. This porous structure enables water to pass through while trapping particles, thereby reducing turbidity runoff while maintaining water flow capability.

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The mineral wool fill material acts as an intermediary between the incoming water flow and the environment. It intercepts and traps sediment particles, preventing them from being carried away in the runoff, thus reducing turbidity while allowing water to flow through the erosion control roll.

Inventive Principle:

Principle #24Intermediary (Mediator)
