Pre-filled Cellular Structures for Rapid Defense Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geotextile cellular systems are collapsible and require time and effort to fill on-site, which is not suitable for rapid formation of solid structures like walls or barriers, and they may not provide adequate robustness for impact or ballistics defense applications.
Innovation Solution
A cellular structure composed of interconnected cells filled with a composite material that includes a particulate material and a bonding agent, providing a solid, resilient, and flexible fill that can be pre-filled and rapidly deployed as a wall or barrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If geotextile cellular systems are made collapsible for flat-pack delivery, then transportation convenience is improved, but deployment time and filling effort increase
Solution Approach 1:
The cellular structures are pre-filled with composite material during manufacturing before delivery. This preliminary action eliminates the need for on-site filling operations, allowing rapid deployment while maintaining the collapsible flat-pack design for convenient transportation.
2Strength
If cellular structures use finer particulate fill materials, then structural integrity is improved, but handling difficulty increases
Solution Approach 1:
The patent uses composite material consisting of finer particulate fill material bonded with a binding agent. This composite formulation provides the structural integrity of fine particles while the binding agent prevents them from scattering during handling and deployment, solving both requirements simultaneously.
3Productivity
If cellular structures are pre-filled for rapid deployment, then productivity is improved, but device complexity increases
Solution Approach 1:
The cellular structures are pre-filled during manufacturing with composite material that includes a binding agent. This preliminary action enables rapid on-site deployment while the binding agent ensures the fill material remains contained and structurally sound throughout handling and deployment operations.
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
The pre-filled cellular structure offers enhanced strength, resilience, and impact resistance, allowing for rapid deployment and effective use in defense applications such as vehicle barriers, flood protection, and ballistics protection without the need for on-site filling.
Implementation Method 1
The bonding agent preferably bonds together the particulate material, which is distributed throughout the fill, and also preferably bonds the composite fill material to the fabric material of the cells
Implementation Method 2
The pre-filled cellular structure offers enhanced strength, resilience, and impact resistance, allowing for rapid deployment and effective use in defense applications such as vehicle barriers, flood protection, and ballistics protection

AI summary
A cellular structure includes a plurality of interconnected cells of fabric material. The cells are at least partially filled with a composite fill material that includes a particulate material and a bonding agent. A cellular unit made up of a plurality of the interconnected cells may have an associated load-bearing frame to enable lifting and/or transportation of the structure. The fill material is preferably resilient.
