Biodegradable Viscose Mesh for Erosion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing environmental control systems for erosion and runoff lack sufficient strength and are not biodegradable, posing challenges in effectively managing soil erosion and pollutant spread during construction and land remediation projects.
Innovation Solution
A biodegradable mesh container filled with a filler material, composed of interlaced viscose fibers, providing a tensile strength of at least 100 pounds per square inch, which can be securely anchored to the earth surface to control erosion and runoff.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional erosion control materials like straw bales and silt fences are used, then they are biodegradable and environmentally friendly, but they lack sufficient strength to effectively control erosion and runoff
Solution Approach 1:
The patent uses a composite structure combining biodegradable viscose fibers with a mesh reinforcement pattern. The viscose provides biodegradability while the mesh structure (formed by interlacing yarns) provides the necessary tensile strength. This composite approach allows the material to achieve both strength requirements and environmental compatibility.
Solution Approach 2:
The patent changes the physical parameters of the biodegradable material by treating viscose fibers to enhance their strength properties. The viscose fibers are processed to achieve specific tensile strength thresholds (at least 100 psi, preferably at least 150 psi or 200 psi) while maintaining their biodegradable nature. This parameter optimization allows natural fibers to meet engineering strength requirements.
2Strength
If synthetic materials are used to provide sufficient strength for erosion control, then the strength requirement is met, but the materials do not biodegrade and require removal after use
Solution Approach 1:
The patent employs a disposable erosion control system made entirely from biodegradable materials. The mesh container and filler material are designed to provide sufficient strength during the construction period, then naturally biodegrade afterward, eliminating the need for removal and long-term maintenance. This approach trades permanent durability for temporary effectiveness combined with environmental compatibility.
Solution Approach 2:
The biodegradable mesh container system is designed to self-destruct through natural biodegradation after serving its erosion control function. The viscose fiber materials break down naturally in the environment, providing a self-service end-of-life solution that eliminates manual removal requirements and returns the site to its natural state.
3Object-generated harmful factors
If a biodegradable mesh container filled with filler material is used, then environmental compatibility is achieved, but the structure must maintain sufficient strength to anchor securely and control runoff
Solution Approach 1:
The system uses a composite structure where the biodegradable mesh container (made from viscose fibers) works in conjunction with a filler material to achieve both environmental compatibility and anchoring reliability. The mesh provides structural integrity for anchoring while the filler material adds weight and stability, together ensuring secure installation without compromising biodegradability.
