Relocatable Concrete Armory Vault with Removable Lifting Cams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing armory vaults lack the combination of high security and mobility, as they are either permanent and immobile or temporary and insecure, with steel vaults being vulnerable to attacks and lacking flexibility in deployment.
Innovation Solution
A relocatable concrete armory vault with metal fiber-reinforced concrete, featuring a dual-room structure with a vestibule and vault area, equipped with a steel vault door, Dutch daygate, and removable lifting cams for easy relocation, providing high security and mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If steel vaults are used for armory security, then security protection is improved, but vulnerability to attacks and lack of mobility worsen
Solution Approach 1:
The patent uses fiber-reinforced concrete as a composite material that combines the strength and security of traditional vault materials with improved mobility characteristics. The concrete structure provides attack resistance while allowing the vault to be relocated as needed, resolving the contradiction between security and mobility.
Solution Approach 2:
The vault design incorporates dynamic elements such as removable lifting cams and a modular structure that enables the vault to transition between stationary secure storage and mobile relocation states. This dynamic capability allows the system to maintain security while adapting to different deployment scenarios.
2Reliability
If permanent vault structures are constructed, then security and attack resistance are improved, but mobility and relocation capability worsen
Solution Approach 1:
The vault is designed as a segmented structure with distinct components including the concrete vault body, removable lifting cams, and separate door assemblies. This segmentation allows the vault to maintain its secure structure while enabling easy relocation by removing and reattaching specific components like the lifting cams.
Solution Approach 2:
The vault incorporates dynamic relocation mechanisms including removable lifting cams that enable the permanent-looking concrete structure to be moved when needed. The dual-door system with daygate and main vault door also provides dynamic access control while maintaining the permanence of the concrete structure.
3Adaptability or versatility
If temporary vault structures are used for mobility, then relocation capability is improved, but security and attack resistance worsen
Solution Approach 1:
The use of fiber-reinforced concrete creates a composite structure that provides temporary vault mobility while maintaining permanent-level security. The concrete material itself provides attack resistance comparable to permanent structures, while the overall system remains relocatable.
Solution Approach 2:
The vault incorporates rounded corners and curved design elements in the concrete structure that both enhance structural strength for attack resistance and facilitate easier relocation by reducing stress concentrations and improving structural integrity during movement.
4Strength
If high-strength concrete is used for vault construction, then attack resistance is improved, but weight and difficulty of relocation worsen
Solution Approach 1:
The concrete vault is designed as a segmented structure with standardized modules and sections. This segmentation allows the high-strength concrete structure to be divided into manageable units that can be relocated more easily while maintaining the overall security and attack resistance of the complete vault system.
Solution Approach 2:
The vault incorporates dynamic relocation aids including removable lifting cams and strategic reinforcement placement that enables the heavy concrete structure to be moved when needed. The concrete provides permanent-level strength while the system maintains temporary-level mobility through these dynamic elements.

AI summary
A relocatable concrete armory includes an outer vestibule and an inner vault separated by a dividing wall. A vestibule door provides entry to the concrete vestibule. A steel vault door and a security daygate are mounted to the dividing wall and provide entry to the concrete vault. The interior surface of the armory includes insulation panels embedded in concrete. The armory can be integrally lifted via removable lifting cams attached to concrete side walls. The concrete has a compressive strength of at least 15,000 psi.
