Single Anchor Terminal for Roadside Wire Rope Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roadside safety systems with cable or wire rope barriers face challenges in being cost-effective, easy to install, and having components that can be easily reused or replaced after a collision, as they often require complex foundational structures and are prone to deformation upon impact.
Innovation Solution
A single anchor terminal system comprising a release post, a brace, and an anchor base, where the cable is releasably coupled to the release post, and the brace supports the release post in an upright position, allowing for easy installation and reuse, with a tension release mechanism that decouples the cable from the anchor upon impact, enabling quick replacement of damaged components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable barrier systems with multiple foundational structures are used, then anchoring stability is improved, but installation complexity and cost increase
Solution Approach 1:
The patent combines multiple anchoring functions into a single integrated anchor terminal structure. The terminal post integrates the cable attachment mechanism, bracing system, and anchoring point into one unified structure, eliminating the need for separate foundational structures while maintaining anchoring stability.
Solution Approach 2:
The single anchor terminal serves multiple functions simultaneously: it provides cable anchoring, structural bracing, and impact force distribution. This multi-functional design replaces traditional systems that required separate components for each function, simplifying installation while maintaining reliability.
2Strength
If traditional cable barrier systems are used, then barrier strength is improved, but ease of replacement after collision deteriorates
Solution Approach 1:
The cable barrier system is divided into modular sections with standardized single anchor terminals. Each terminal can be independently replaced after collision without affecting adjacent sections, facilitating quick repair while maintaining overall barrier strength through the modular design.
Solution Approach 2:
The design allows damaged anchor terminals to be quickly discarded and replaced with pre-fabricated units. The standardized interfaces enable rapid installation of replacement terminals, minimizing repair time while the robust construction ensures recovered terminals maintain full barrier strength.
3Force
If robust foundational structures are used, then collision resistance is improved, but cost and installation time increase
Solution Approach 1:
The anchor terminals are pre-assembled with integrated bracing and attachment mechanisms before field installation. This preliminary preparation allows for rapid deployment that maintains full collision resistance, eliminating the time-consuming on-site assembly required by traditional foundational structures.
Solution Approach 2:
The single anchor terminal uses a simplified, standardized design that can be quickly installed and replaced. While individual terminals are relatively simple structures, the system achieves adequate collision resistance through proper distribution of impact forces across multiple terminals, allowing faster installation compared to complex foundational structures.

AI summary
A single anchor terminal is provided for a roadside wire rope barrier. The single anchor terminal includes a release post, a brace, and an anchor base. The brace supports the release post in an upright position and extends from the release post to the anchor base. The brace has a first portion attached to the release post and a second portion coupled to the first portion with a release component. The anchor base includes a main post that supports the release post and a brace anchor that is coupled to the main post.
