Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional prefabricated temporary structures are inadequate for emergency or military applications in remote locations due to their lack of adaptability to uneven terrain, requiring lightweight, easily assembled, and rigid structures that can withstand undesirable environmental conditions.
Innovation Solution
A modular deck system with adjustable leg assemblies and a rigid wall system that can be assembled into various shapes and sizes, accommodating uneven terrain through telescopic legs and a modular design, allowing for rapid deployment and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional prefabricated temporary structures are used, then construction speed is improved, but adaptability to uneven terrain deteriorates
Solution Approach 1:
The deck system is divided into modular deck unit modules that can be independently assembled. Each module contains adjustable leg assemblies that can be configured separately to accommodate terrain variations, allowing the overall structure to adapt to uneven ground while maintaining rapid construction through standardized modular units
Solution Approach 2:
The leg assemblies incorporate telescopic members that can dynamically adjust their length to compensate for terrain variations. The adjustable legs allow the deck surface to remain level regardless of underlying terrain conditions, providing adaptability while maintaining construction speed through a standardized adjustment mechanism
2Stability of the object's composition
If permanent structures are used, then structural stability is improved, but transportability deteriorates
Solution Approach 1:
The structure is segmented into transportable modular units that can be disassembled and relocated. The deck unit modules with adjustable leg assemblies can be configured for stability during use but can also be disassembled for transport, balancing structural stability with transportability through modular design
Solution Approach 2:
The leg assemblies can change their configuration parameters (telescopic extension, joint angles) to provide different levels of stability. During transport, the structure can be configured in a more compact state, while during use, the legs extend and lock into position to provide maximum structural stability
3Strength
If rigid temporary structures are used, then structural integrity is improved, but ease of assembly deteriorates
Solution Approach 1:
The rigid structure is achieved through segmented modular components with standardized connection interfaces. The deck unit modules can be easily assembled together using standardized joints, while the overall structure maintains structural integrity through the modular rigid connections between segments
Solution Approach 2:
The leg assemblies use dynamic adjustable mechanisms that simplify assembly. The telescopic legs with pinned and threaded interfaces allow for easy height adjustment and locking, providing rigid structural integrity once assembled while maintaining ease of assembly during construction

AI summary
An Emergency Isolation and Treatment Shelter (EITS) deck system is constructed from a multiple of deck unit modules. Each deck unit module includes four adjustable leg assemblies attachable together by a lower truss between each leg assembly so as to support a deck surface panel. The size of the deck unit module defines the modularity of the EITS. Each leg assembly includes a primary leg, an intermediate leg, and a screw foot each in telescopic relationship. Each leg assembly may be telescoped independently to provide a level deck surface irrespective of the underlying terrain.
