Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle security barriers are permanently installed and lack the ability to be temporarily deployed or moved, making them unsuitable for situations requiring temporary traffic control without the cost and time of permanent installation.
Innovation Solution
A portable vehicle barrier with a pivotally movable beam actuated by a hydraulic cylinder, featuring a central base with pointed teeth and hinged front and rear sections that can be easily transported, deployed, and redeployed, allowing for temporary and effective traffic control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional vehicle security barriers are permanently installed in concrete, then stopping power and structural stability are improved, but portability and deployment flexibility deteriorate
Solution Approach 1:
The barrier is divided into modular components including a beam, front support assembly, rear support assembly, and base assembly that can be detached and repositioned. This segmentation enables the barrier to be transported and redeployed to different locations while maintaining structural integrity and stopping power when assembled.
Solution Approach 2:
The barrier transitions from a static permanent installation to a dynamic portable structure. The support assemblies can pivot between engaged and disengaged positions, and the entire barrier can be collapsed for transport and raised for operation, providing adaptability between storage and deployment states.
2Stability of the object's composition
If conventional barriers use heavy concrete anchoring, then stability and resistance to vehicle impact are improved, but ease of transport and rapid deployment deteriorate
Solution Approach 1:
The base assembly incorporates a counterweight mechanism that provides stability when the barrier is deployed without requiring concrete anchoring. The counterweight compensates for the forces generated during vehicle impact, maintaining stability through gravitational balance rather than permanent mechanical anchoring.
Solution Approach 2:
Hydraulic cylinders are used to raise and lower the beam between horizontal and vertical positions, providing controlled movement and stable positioning without requiring heavy manual handling or permanent installation structures.
3Strength
If permanent plate barriers are used, then stopping power is improved, but the ability to relocate for temporary traffic control deteriorates
Solution Approach 1:
The barrier is pre-assembled in modular components that can be quickly configured at the deployment location. The support assemblies are pre-positioned on the base, and the beam is pre-connected, allowing rapid deployment without requiring time-consuming concrete pouring or heavy equipment installation.
Solution Approach 2:
The barrier employs dynamic positioning mechanisms including pivotable support assemblies and a height-adjustable beam that can be rapidly deployed and repositioned. The ability to quickly transition between assembled and disassembled states eliminates the time loss associated with permanent barrier installation and relocation.

Function Achieved in This Case
The portable barrier can be quickly and easily moved to different locations, providing effective temporary traffic control by pivoting into an active position to stop vehicles, with the teeth engaging the tires and road surface to restrict movement, while also being compact and lightweight for easy transportation.
Implementation Method 1
an actuator apparatus that is operated to pivot the beam vertically
Implementation Method 2
the teeth engaging the tires and road surface to restrict movement

AI summary
A portable vehicle barrier is transportable to a desired location, unfolded from a compact transport configuration and deployed to provide an effective vehicle barrier that can be used temporarily and then refolded into the compact transport configuration and transported to a remote location for utilization or storage. The vehicle barrier is formed with a central base having front and rear sections that are pivotally hinged to the central base. A barrier member can be selectively activated to rise into an active position and restrain the passage of vehicles. An impact into the barrier member causes the central base to tip in order to drive pointed teeth into the tires of the vehicle and into the underlying road surface and stop the impacting vehicle. The front and rear sections have vertical bars that move into a nesting horizontal position when the front and rear sections are pivoted into the transport position.
