Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rapid deployable traffic barriers are often too slow to deploy, require significant construction efforts, lack modularity for limited duration requirements, and do not provide adequate protection against larger vehicle threats, especially in urban environments.
Innovation Solution
A deployable expedient traffic entry regulator (DETER) system that integrates a pre-kitted wedge barrier into a QuadCon ISO container, featuring a sliding friction matting system and modular connectivity, allowing for rapid deployment and effective hostile vehicle mitigation against box trucks and larger class vehicles without the need for anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional rapid deployable traffic barriers are used, then deployment speed is improved, but deployment time is still too slow and construction effort is significant
Solution Approach 1:
The barrier system is pre-assembled and pre-positioned within the container structure, with all components prepared in advance. The wedge barrier, friction mats, and structural elements are integrated into the container before deployment, eliminating on-site assembly time and enabling immediate deployment when needed.
Solution Approach 2:
The barrier system is divided into modular segments including the container structure, wedge barrier components, friction mats, and support elements. These segmented components can be independently prepared and rapidly deployed as a coordinated system, improving deployment speed while maintaining structural integrity.
2Adaptability or versatility
If conventional traffic barriers are used, then barrier function is provided, but modularity for limited duration requirements is lacking
Solution Approach 1:
The container structure incorporates movable and adjustable components including hinged side walls, removable end walls, and adjustable top panels. These dynamic elements allow the barrier configuration to be adapted for different deployment durations and operational requirements, transitioning from a static structure to a versatile system.
Solution Approach 2:
The container structure serves multiple functions: it provides structural support, houses the wedge barrier, contains friction mats, and can be configured for different deployment scenarios. The same basic structure adapts to various duration requirements and operational needs, eliminating the need for multiple specialized barrier systems.
3Strength
If conventional traffic barriers are used, then basic vehicle stopping is achieved, but protection against larger vehicle threats is inadequate
Solution Approach 1:
The barrier system combines multiple materials and mechanisms: a rigid wedge barrier for structural resistance, friction mats for tire engagement, and a reinforced container structure. This composite approach creates a multi-layered defense system that effectively stops larger vehicle threats by combining different physical principles and material properties.
Solution Approach 2:
The system merges the wedge barrier, friction mats, and container structure into an integrated barrier system. The wedge barrier provides initial vehicle deflection, the friction mats enhance tire engagement and stopping capability, and the container structure provides overall structural support, creating a unified system with enhanced stopping power against larger vehicles.
4Productivity
If pre-kitted wedge barrier is integrated into QuadCon container, then deployment rapidity is improved, but device complexity increases
Solution Approach 1:
The wedge barrier and friction mat components are nested within the container structure, with each component fitting into designated spaces. The container acts as a housing that organizes and protects the barrier components, allowing rapid deployment by simply opening the container and positioning the pre-assembled components.
