Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geotextile sand containers face challenges in secure and tool-free closure, particularly in harsh environments and with thick geotextiles, leading to inefficiencies and high maintenance costs due to the need for specialized equipment and trained personnel.
Innovation Solution
A geotextile sand container with a quick-release fastener, such as a Velcro hook and loop system, that allows for tool-free closure of the filling opening, ensuring a secure and reliable seal without the need for sewing machines, crimping machines, or other tools, even in adverse conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sewing machines or crimping machines are used to close the filling opening, then the closure is secure and leak-proof, but the operation requires trained personnel and specialized equipment, increasing complexity and maintenance costs
Solution Approach 1:
The geotextile sand container is designed with a self-closing mechanism where the geotextile material itself forms the closure structure. The filling opening is closed by folding the geotextile material over and securing it with integrated fastening elements, eliminating the need for external sewing or crimping equipment. This self-service approach allows untrained personnel to securely close the container without specialized tools.
2Reliability
If sewing machines are used to close thick geotextiles, then the closure is secure, but the machine needles break frequently and seam quality is insufficient
Solution Approach 1:
The invention replaces the mechanical needle-based sewing system with a folding and fastening mechanism. Instead of using needles that penetrate and break in thick geotextile material, the closure is achieved by folding the geotextile layers and securing them with fastening elements such as clips, ties, or integrated fastening systems that distribute stress without requiring needle penetration through multiple thick layers.
3Reliability
If crimping machines are used to close the filling opening, then the closure is secure, but the equipment requires compressed air or electricity supply which is not always available on construction sites
Solution Approach 1:
The closure mechanism is designed to be entirely manual and self-contained, requiring no external power sources. The geotextile material is folded over the filling opening and secured using mechanical fastening elements that can be operated by hand, making the system fully adaptable to remote construction sites without electricity or compressed air supply.
4Reliability
If sewing machines are used in damp or wet environments, then the closure is secure, but the risk of electric shock increases and the machines are susceptible to contamination and malfunctions
Solution Approach 1:
The manual folding and fastening mechanism eliminates all electrical components from the closure process. Operators simply fold the geotextile material and secure it with mechanical fasteners, completely avoiding the risk of electric shock in wet environments. The mechanical nature of the closure system also makes it resistant to contamination and malfunctions that plague electrical sewing equipment in harsh construction site conditions.
