Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security barriers are not suitable for civil engineering applications as they are not easily transportable, installable, or removable, and often cause protruding parts that pose dangers to crowds, while also being ineffective at stopping vehicles at high speeds in limited spaces.
Innovation Solution
A safety barrier with a serrated or tapered spur design that penetrates deeper into the soil, equipped with stiffening structures and a tire killer to disable vehicles, and a base plate with increased friction and a telescopic design to prevent lifting, allowing for efficient stopping and immobilization of vehicles without protruding parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed structures with fixings or anchors are used to protect sensitive objects, then stopping efficiency is improved, but transportability and ease of installation are worsened
Solution Approach 1:
The barrier is divided into modular components: a base plate with anchoring elements, a frame structure, and vertical bars. This segmentation allows the barrier to be transported in manageable parts and assembled on-site without requiring heavy machinery or permanent foundation work, thus maintaining both stopping efficiency and transportability.
Solution Approach 2:
The base plate incorporates pre-designed anchoring elements (spurs with serrated or tapered edges) that are prepared in advance. These elements are designed to penetrate and anchor into the ground upon impact or during installation, providing immediate anchoring capability without requiring complex installation procedures or heavy equipment.
2Ease of operation
If modular reconfigurable barriers are used for civil engineering applications, then ease of installation and transportability are improved, but stopping efficiency against high-speed vehicles is worsened
Solution Approach 1:
The vertical bars are designed with specific geometric features (inclined upper sections orthogonal to load-bearing bars) that concentrate impact forces onto the anchored base plate. The spurs on the base plate have optimized shapes (serrated or tapered) that maximize ground penetration and anchoring strength. These localized quality enhancements ensure high stopping efficiency despite the modular nature of the barrier.
Solution Approach 2:
The spurs on the base plate feature curved or tapered geometries rather than flat surfaces. This curvature allows the spurs to more effectively penetrate and anchor into the ground upon impact, converting the horizontal impact force into vertical anchoring force, thereby improving stopping efficiency while maintaining modular design.
3Reliability
If conventional barriers like Jersey-type road barriers are used, then stopping capability is improved, but weight and bulk are increased, making transport and removal difficult
Solution Approach 1:
Instead of relying on the barrier's own weight to stop vehicles, the design uses anchoring elements (spurs) that transfer impact forces into the ground. The lightweight modular structure compensates for its low mass through these anchoring mechanisms, achieving high stopping capability without requiring heavy materials or bulky construction.
Solution Approach 2:
The barrier replaces the traditional mass-based stopping mechanism (heavy concrete barriers) with a force-transfer mechanism. The modular frame and anchored base plate create a mechanical system that transfers vehicle impact forces into the ground through the spurs, eliminating the need for heavy weights while maintaining stopping effectiveness.
4Reliability
If barriers are designed to stop vehicles effectively, then stopping efficiency is improved, but protruding parts are created that pose dangers to surrounding crowds
Solution Approach 1:
The potentially dangerous protruding elements (spurs and anchoring features) are extracted from the visible barrier structure and placed underground within the base plate. Only the essential frame and vertical bars remain visible above ground, eliminating hazardous protrusions while maintaining the anchoring functionality needed for effective vehicle stopping.
Solution Approach 2:
The anchoring spurs are nested within the base plate structure, with the sharp or serrated edges positioned to penetrate the ground while the bulk of the anchoring mechanism remains concealed within or below the surface level. This nesting allows the barrier to achieve strong ground anchoring without exposing dangerous protrusions to the surrounding environment.
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 safety barrier effectively stops and immobilizes vehicles by penetrating deeper into the ground, reducing deformation, and preventing vehicle parts from protruding, thus ensuring crowd safety and efficient deployment in urban areas.
Implementation Method 1
The spur can be tapered to a point, i.e. have an arrowhead shape or the form of a claw. This allows the spur to penetrate deeper and more firmly into the ground.
Implementation Method 2
The base plate can have a front section extending forward from the frame, the length of which is selected to be greater than or equal to the distance between the front tires and the front of a truck.
Implementation Method 3
The base plate can incorporate a tire killer, which may be made of one or more pointed metal plates. This allows the vehicle to be rendered inoperable even before impact with the frame.
