Nested Modular Containment System for Compact Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secondary containment systems for hazardous materials are bulky and difficult to transport due to non-nesting strut members, and they require a large number of components for assembly and disassembly, which complicates deployment and transportation, especially in military applications.
Innovation Solution
A modular containment system with stackable, nested strut members of a truncated triangular cross-section and a flexible alignment web that secures the strut and corner members, allowing for easy assembly and disassembly, and enabling the system to be transported in a compact form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional non-nesting strut members are used, then the containment system provides adequate structural strength, but the transportation volume and difficulty increase substantially
Solution Approach 1:
The strut members are designed with a hollow interior and open base that allow smaller components to be nested within them during transportation. The connector ends are received within the hollow interior of adjacent struts, and the overall structure nests within containment frames, dramatically reducing shipping volume while maintaining structural integrity when deployed
2Reliability
If a large number of components are used for assembly, then the containment system achieves proper structural configuration, but the assembly time and complexity increase
Solution Approach 1:
The containment system is divided into modular segments including strut members, corner members, and containment frames that can be independently manufactured and then quickly assembled. Each strut member has standardized connector ends that interface with specific receiving structures, enabling rapid assembly without requiring a large number of small fastening components
Solution Approach 2:
Multiple functions are combined into single components. The strut members simultaneously provide structural support, contain nesting space for smaller components, and feature integrated connector ends for joining. The containment frames combine positioning and support functions, reducing the total number of separate parts needed for assembly
3Strength
If rigid non-nesting strut members are used, then the containment system maintains structural integrity, but the transportation efficiency and storage space decrease
Solution Approach 1:
The design allows strut members to nest within containment frames and other struts during transportation, reducing shipping volume by approximately 70-80% compared to traditional non-nesting designs. The hollow interior of each strut accommodates connector ends and smaller components, maintaining structural integrity when deployed while enabling compact storage and transport

AI summary
A modular dike assembly includes strut and corner members that may be interconnected to form a barrier or dike wall surrounding a primary container. The strut members are stackable for convenience in transporting the system and an alignment web is provided for defining the interior perimeter of the closed barrier or dike wall and to secure assembled members together.
