Modular Vehicle Barrier Segmentation for Crash Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of effective and portable anti-ram vehicle barriers suitable for temporary sites such as fairs, street parties, and sporting events, which are often large and difficult to transport and set up, leading to high costs and logistical challenges.
Innovation Solution
A modular vehicle barrier system comprising a rigid, L-shaped framework with a base and upright portion, designed to be lightweight and easily transportable, which can be stacked efficiently and quickly assembled to provide crash-rated protection against vehicles, meeting standards like ASTM F2656 for penetration ratings and impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anti-ram vehicle barriers are used to provide crash-rated protection, then safety and penetration resistance are improved, but weight and difficulty of transport increase
Solution Approach 1:
The barrier is divided into multiple modular units that can be separately transported and assembled. Each module contains a standardized wedge element and framing structure, allowing the total barrier length to be achieved through assembly of lighter individual components rather than moving a single heavy structure.
Solution Approach 2:
The modular modules are designed to nest within each other during transport, with smaller modules fitting inside larger ones. This nesting arrangement maximizes transport efficiency and reduces the space and weight impact of carrying multiple barrier modules, while maintaining the full protective capability when assembled.
2Reliability
If traditional anti-ram vehicle barriers are used to ensure crash ratings, then stopping capability is improved, but ease of deployment and setup time worsen
Solution Approach 1:
The barrier system is segmented into self-contained modular units with standardized connection interfaces. This segmentation allows for rapid assembly through simple mechanical connections rather than complex installation procedures, enabling quick deployment while maintaining certified stopping capability through the engineered wedge geometry and module configuration.
Solution Approach 2:
The modular units are pre-configured with standardized connection mechanisms and pre-positioned wedge elements during manufacturing. This preliminary preparation of connection interfaces and component arrangement eliminates the need for complex on-site assembly procedures, allowing deployment teams to quickly assemble the barrier by simply connecting pre-prepared modules together.
3Ease of operation
If modular design is used to improve transport efficiency, then ease of transport and stacking is improved, but structural complexity increases
Solution Approach 1:
The modular design employs universal connection interfaces and standardized component dimensions that serve multiple functions: structural connection, transport handling, and stacking configuration. This universality reduces the variety of unique parts needed, simplifying the overall system complexity while enabling efficient transport and assembly operations across different barrier configurations.

AI summary
An exemplary modular vehicle barrier includes a rigid, generally L-shaped frame having a base and an upright portion. The base including two or more joists spaced apart and extending orthogonal to a foot plate, wherein the foot plate is attached to a bottom surface at a front end of the two or more joists, the upright portion configured in a ladder arrangement having spaced apart vertical posts secured at bottom ends to a bottom beam and at top ends to a top beam, wherein the bottom beam is attached to a top surface at a back end of the two or more joists, and a wedge point formed the bottom surface of the second end of the two or more joists.
