Towable Traffic Barrier With Restrictor Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing towable traffic barriers experience 'wandering' during towing and are prone to bending or displacement upon impact due to inadequate control and stabilization of interconnected modules.
Innovation Solution
The implementation of a towable, articulated elongated traffic barrier with rigid, double-ended modules connected by an articulating interconnection and restrictor structure, along with dual wheel assemblies and a drag mechanism to resist bending and stabilize the barrier during towing and repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traffic barrier sections are pivotally connected to enable repositioning, then adaptability and ease of repositioning are improved, but control during towing deteriorates causing sections to wander
Solution Approach 1:
The patent applies dynamics by making the connector structure adjustable between two states: an articulated configuration that allows pivoting for repositioning and adaptability, and a restricted configuration that limits articulation to prevent wandering during towing. This dynamic switching between flexible and rigid states resolves the contradiction between adaptability and stability.
2Adaptability or versatility
If modular barrier sections are connected together, then ease of repositioning and adaptability are improved, but structural stability upon impact deteriorates causing bending or displacement
Solution Approach 1:
The connector structure dynamically transitions between articulated and restricted configurations. When restricted, it provides structural stability to resist bending upon impact while maintaining the modular design for reconfiguration capability. This resolves the contradiction between modular adaptability and impact resistance.
3Ease of operation
If wheel assemblies are added to support barrier sections, then ease of towing is improved, but device complexity increases
Solution Approach 1:
The wheel assemblies are integrated into the existing connector structure, serving multiple functions: supporting barrier sections during towing, enabling articulation for repositioning, and potentially providing stabilization. This multi-functionality reduces overall device complexity compared to adding separate components for each function.
