Elastomeric V-Shaped Security Barrier for Impact Energy Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security barriers for roadways are time-consuming to install and cause significant damage to vehicles and their occupants upon impact, and they can be breached by fast-moving vehicles or disintegrate upon explosion, leading to potential harm from debris.
Innovation Solution
A security barrier constructed from elastomeric material, preferably reclaimed rubber, with a V-shaped cross-section and a right-angle configuration for stability, designed to deform and remain in contact with the ground during impacts, minimizing displacement and damage, and arranged in sections for easy installation and potential use in chains to manage vehicle momentum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional concrete or brick walls are used as security barriers, then the barrier strength and protection capability are improved, but the installation time and material preparation requirements increase significantly
Solution Approach 1:
The barrier is divided into multiple pre-manufactured modular sections that can be quickly assembled on-site. Each section contains standardized connection points and interfaces, allowing rapid installation without extensive preparation work. The segmented design maintains overall barrier strength while dramatically reducing installation time and labor requirements.
2Strength
If traditional concrete or brick walls are used as security barriers, then the barrier strength is improved, but the damage to vehicles and occupants upon impact increases significantly
Solution Approach 1:
The barrier material properties are changed from rigid concrete/brick to a more compliant material that can deform elastically upon impact. This parameter change allows the barrier to absorb impact energy through controlled deformation rather than transferring it to the vehicle, significantly reducing damage to vehicles and occupants while maintaining barrier effectiveness.
Solution Approach 2:
The barrier incorporates energy-absorbing elements and deformable structures designed to cushion impacts before they reach the vehicle. The material composition and structural design are optimized to provide progressive resistance, initially yielding to impact forces and then providing stopping power, thereby reducing peak impact forces on vehicles and occupants.
3Strength
If traditional concrete or brick walls are used as security barriers, then the barrier strength is improved, but the barrier can disintegrate upon explosion causing debris harm
Solution Approach 1:
The barrier material is changed from brittle concrete/brick to a more ductile and cohesive material that resists fragmentation under explosive loads. This parameter change ensures that even when subjected to explosion forces, the barrier maintains structural integrity and does not disintegrate into harmful debris, while still providing effective protection against vehicle ramming attacks.
4Ease of operation
If the barrier is made lighter for easy installation, then the installation ease is improved, but the barrier stability and resistance to vehicle impact decrease
Solution Approach 1:
The barrier is designed as modular sections that are lightweight enough for easy handling and installation by small teams, yet when assembled together with proper connection mechanisms, they form a stable and rigid structure capable of resisting vehicle impacts. The segmentation allows for easy transport and installation while the collective assembly provides the necessary stability.
Solution Approach 2:
The barrier employs composite material construction that combines lightweight components with high-strength elements. This allows the individual sections to be light and easy to install, while the composite structure as a whole provides the strength and stability needed to withstand vehicle impacts and maintain barrier integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The elastomeric barrier allows for quick installation, minimizes vehicle damage and debris upon impact or explosion, and effectively reduces vehicle momentum through friction and deformation, remaining intact to stop subsequent vehicles, thus enhancing safety and security.
Implementation Method 1
the barrier can rest stably on uneven or contoured ground. The arched profile also allows for deformation during a vehicle impact, enabling the barrier to remain in frictional contact with the ground so as to minimise the displacement of the barrier caused by the vehicle impact.
Implementation Method 2
enabling the barrier to remain in frictional contact with the ground so as to minimise the displacement of the barrier caused by the vehicle impact.
