Modular Traffic Barrier Loop Connections Without Ground Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cement or concrete barriers for highway safety require pins to be driven into the ground for stability during vehicle impacts, necessitating post-installation work and potential damage during removal.
Innovation Solution
A modular traffic barrier system with integrated loop and pin connectors allows barriers to be connected without ground pins, using loop connectors and pins to form moment connections, and optionally incorporating deflection spacers like shims or blocks to reduce deflection and roll during impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If ground pins are used to secure barriers during vehicle impacts, then barrier stability is improved, but installation complexity and potential damage increase
Solution Approach 1:
The connector merges the functions of ground anchoring and barrier connection into a single integrated component. The U-shaped configuration allows the connector to engage with both the ground (via the curved bottom) and the barrier ends (via the upward extending arms), eliminating the need for separate ground pins and simplifying the overall system.
Solution Approach 2:
The connector acts as an intermediary element between the ground and the barrier. Rather than directly driving pins into the ground and separately attaching barriers, the connector mediates this connection by providing a unified interface that secures both elements together, reducing installation steps and potential damage.
2Reliability
If ground pins are driven into the ground for barrier stability, then barrier reliability during impact is improved, but removal complexity and damage increase
Solution Approach 1:
The connector design enables dynamic adjustment between installation and removal states. During installation, the flexible nature of the connector allows it to be positioned and secured. During removal, the same flexibility enables easy extraction without damaging the barrier or ground, as the connector can be maneuvered out of its engaged position.
Solution Approach 2:
The connector is designed to be recoverable and reusable rather than disposable. After securing the barrier during impact events, the connector can be retrieved and reused for subsequent installations, eliminating the need to discard damaged ground pins and reducing long-term costs and complexity.
3Stability of the object's composition
If multiple ground pins are used to secure barriers, then barrier stability during impact is improved, but installation time and complexity increase
Solution Approach 1:
The connector is segmented into functional zones: the curved bottom portion for ground engagement and the upward extending arms for barrier connection. This segmentation allows each part to perform its specific function efficiently, enabling a single connector to provide stability equivalent to multiple ground pins while reducing installation time.
Solution Approach 2:
The connector serves multiple functions simultaneously: it anchors to the ground, connects barrier ends, provides impact resistance, and enables easy removal. This multi-functionality replaces the need for multiple specialized components (multiple ground pins, separate connection elements), thereby reducing installation time and complexity while maintaining stability.

AI summary
Systems, apparatuses, and methods for the connection of modular traffic barriers, where loop connectors, such as pin and loop or hook connectors, are integrated into each end of a barrier allowing the ends of two barriers to be aligned to allow the protruding loops of a loop connector on one end of a barrier to align and connect with the loops of a loop connector on the end of the second barrier, allowing for tension and compression of each end of each barrier.
