Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional temporary shelters used in military applications face issues such as corrosion, water leakage, and complex assembly processes, which hinder rapid assembly and effective protection for personnel and equipment.
Innovation Solution
A modular structure with pre-fabricated panels joined via panel and roof joining assemblies, incorporating shear pins and gaskets to prevent moisture ingress and allow for flexible alignment, enabling rapid assembly and enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional PTM panels are assembled with ratchet locks requiring direct alignment, then the structure provides adequate shelter protection, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent introduces panel joining assemblies with alignment features as intermediaries between panels. These assemblies include alignment ribs and corresponding recesses that guide panel positioning, eliminating the need for direct panel-to-panel alignment while maintaining structural integrity and shelter protection.
Solution Approach 2:
The patent employs standardized panel joining assemblies that can be repeatedly used across multiple panel connections. These modular joining components replicate the same alignment and connection functionality at each joint, simplifying the assembly process through consistency and reducing the skill level required for assembly.
2Strength
If conventional PTM uses polyurethane to bond aluminum to foam, then the structure is formed, but moisture absorption causes delamination and corrosion
Solution Approach 1:
The patent changes the material parameter from polyurethane adhesive to alternative bonding methods or materials that do not absorb moisture. This may include using mechanical fastening systems, corrosion-resistant adhesives, or sealed joint designs that maintain bond strength while preventing moisture ingress that causes delamination and corrosion.
Solution Approach 2:
The patent employs composite panel constructions with moisture-barrier layers integrated into the panel structure. These composite designs include sealed edges, protective coatings, and moisture-resistant core materials that prevent moisture penetration while maintaining the structural integrity of the aluminum-foam-aluminum sandwich construction.
3Productivity
If temporary shelters are assembled rapidly in remote locations, then deployment time is reduced, but assembly simplicity must be maintained without compromising shelter adequacy
Solution Approach 1:
The patent divides the shelter into modular panels with standardized joining assemblies. Each panel is a self-contained module with pre-attached joining features, allowing rapid assembly through simple connection operations. The segmentation enables parallel assembly operations and reduces the need for complex on-site fabrication or alignment procedures.

AI summary
A modular structure formed by panels is disclosed, having a center compartment and first and second side compartments coupled to the opposing sides of the center compartment. Each panel of the modular structure is joined to each respective adjacent panel via a panel joining assembly to substantially prevent moisture from entering the modular structure. An upper roof panel coupled to the center compartment is joined to first and second lower roof panels coupled to the first side compartment and the second side compartment, respectively, via first structural joining assemblies so that the upper roof panel is elevated relative to the first and second lower roof panels to substantially prevent moisture from entering the modular structure.
