Elastic Filter Barrier for Rollable Sediment Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sediment-bearing water barriers are limited by their inability to be rolled and transported efficiently due to fixed lengths, requiring storage and installation in short sections, and lack effective methods for cleaning and reusing contaminated barriers.
Innovation Solution
A novel barrier system featuring a load-bearing apertured material and a filter material with adjustable length, allowing the barrier to be rolled and unrolled for extended installation, and a method for cleaning by passing through rollers with water and steam to remove contaminants, enabling efficient storage, transportation, and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional filter materials with fixed length are used, then the barrier can be installed in short sections, but the barrier cannot be rolled up for storage and transportation
Solution Approach 1:
The filter material is designed with dynamic properties allowing it to be rolled and unrolled while maintaining filtration effectiveness. The material comprises apertures that remain functional regardless of the material's length configuration, enabling transition between compact rolled storage and extended installation states.
Solution Approach 2:
The invention changes the parameter of filter material length from fixed to variable. The filter material can be manufactured in extended lengths but rolled up for storage and transportation, then unrolled at the jobsite for installation over extensive lengths (e.g., 25-300 feet), maintaining filtration effectiveness throughout.
2Productivity
If the filter material length is extended for continuous installation, then storage and transportation efficiency improves, but the filter may become ineffective if length changes
Solution Approach 1:
The filter material is designed with dynamic properties allowing it to be rolled and unrolled while maintaining filtration effectiveness. The material comprises apertures that remain functional regardless of the material's length configuration, enabling transition between compact rolled storage and extended installation states.
Solution Approach 2:

The filter material can be manufactured in extended lengths but rolled up for storage and transportation, then unrolled at the jobsite for installation over extensive lengths (e.g., 25-300 feet), maintaining filtration effectiveness throughout.
3Productivity
If barriers are removed and cleaned as one continuous piece, then cleaning efficiency improves, but the barrier must maintain structural integrity during cleaning
Solution Approach 1:
The barrier system is designed with flexible yet strong materials that can be rolled and unrolled for cleaning operations. The load-bearing material and filter material are attached in a way that maintains structural integrity during handling, cleaning through rollers with water/steam, and reinstallation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous or semi-continuous installation and efficient cleaning of barriers, allowing for extended lengths and improved sediment filtration without clogging, enhancing storage, transportation, and maintenance efficiency.
Implementation Method 1
cleaning the removed barrier by a process which preferably includes passing the removed barrier through a plurality of operations, for example over a plurality of rollers on or between which the barrier is cleaned at least partially by water and/or by steam
Implementation Method 2
cleaning the removed barrier by a process which preferably includes passing the removed barrier through a plurality of operations, for example over a plurality of rollers on or between which the barrier is cleaned at least partially by water and/or by steam

AI summary
An elongate barrier comprising an elongate apertured load-bearing sheet material and an elongate apertured filter material attached to the load-bearing sheet material. The length of the filter material can be changed elastically so that the barrier material can be transported in the form of a roll which can be unrolled for installation.
