Dual-Tier Vehicle Barrier System for Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety barriers are insufficiently strong or inadequately sized to effectively protect buildings from vehicle impacts, particularly in high-risk areas, and large concrete or steel walls are costly and aesthetically unappealing.
Innovation Solution
A dual-tier vehicle safety barrier system comprising a front barrier and a rear barrier, where the rear barrier is taller and positioned closer to the building, with a frame structure that includes elongate arm-like members to absorb and contain impact energy, minimizing material usage and aesthetic impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional safety barriers are used, then the barrier system is simple and cost-effective, but the barrier is insufficiently strong to adequately protect buildings from vehicle impacts
Solution Approach 1:
The barrier system is divided into two separate barrier means positioned at different locations and heights. The first barrier means is positioned closer to the roadway at a lower height, while the second barrier means is positioned closer to the building at a greater height. This segmentation allows each barrier to be optimized for its specific function while together providing comprehensive protection.
Solution Approach 2:
The invention introduces a vertical dimension to the barrier system by positioning the second barrier means at a greater height than the first barrier means. This creates a multi-level protection system where barriers operate at different vertical levels, effectively increasing the protected zone without requiring a single massive wall.
2Strength
If large concrete or steel walls are built to add protection, then the protective strength is improved, but the cost increases significantly and the aesthetic appearance is reduced
Solution Approach 1:
Instead of constructing a single large continuous wall, the system uses multiple smaller barrier means segmented at different locations and heights. This segmentation allows for a less obtrusive visual profile while maintaining protective functionality through the distributed barrier arrangement.
Solution Approach 2:
The barrier system applies different barrier configurations to different locations - the first barrier means closer to the roadway and the second barrier means closer to the building at greater height. This local differentiation provides effective protection where needed while minimizing visual impact in areas where barriers are more visible.
3Strength
If large concrete or steel walls are built to add protection, then the protective strength is improved, but the cost increases significantly
Solution Approach 1:
The protective function is distributed across multiple smaller barrier means rather than concentrated in a single large wall. This segmentation reduces the amount of material required for each individual barrier while the combined effect of multiple barriers provides equivalent or superior protection.
Solution Approach 2:
By utilizing vertical space with barriers at different heights, the system increases protective coverage without proportionally increasing material quantity. The second barrier means positioned at greater height extends the protected zone vertically, providing additional protection leverage from the same material investment.

AI summary
A barrier system is provided including at least a first front barrier and at least a second rear barrier. The second rear barrier is located a pre-determined spaced distance behind the front barrier. At least a part of said second rear barrier is substantially greater in height than the height of said first front barrier.
