Cable-Reinforced Barrier Assembly for Impact-Stable Cable Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barriers face challenges in effectively combining multiple cables and bollards to form a robust structure that can withstand vehicular and footbound intrusions while maintaining structural integrity under high-impact conditions.
Innovation Solution
A kit comprising elongate cables, hollow bollards, multi-part closures, and various brackets is used to create a barrier system with a primary structure for vehicular resistance and a secondary structure for footbound protection, utilizing cable entry ports, closure attachment openings, and various brackets for secure assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple cables and bollards are combined to form a robust barrier structure, then resistance to vehicular and footbound intrusions is improved, but structural integrity under high-impact conditions deteriorates due to cable misalignment and assembly complexity
Solution Approach 1:
A cable placement block is introduced as an intermediary component between the bollard and the cables. This block features multiple cable channels that precisely guide and position each cable, ensuring proper alignment and spacing. The cable placement block mediates the connection between structural elements and flexible cables, preventing misalignment and maintaining structural integrity under impact loads.
Solution Approach 2:
The barrier system is segmented into distinct functional components: bollards for vertical support, cable placement blocks for cable positioning, closures for opening coverage, and brackets for attachment. Each segment performs a specific function, allowing for optimized performance and easier assembly while maintaining overall structural reliability.
2Ease of manufacture
If cable entry ports and closure attachment openings are used to assemble the barrier, then ease of manufacture is improved, but device complexity increases due to multiple parts and assembly steps
Solution Approach 1:
Multiple functional features are merged into integrated components. The cable placement block combines cable guidance, positioning, and structural support functions. The closure integrates multiple opening types (cable openings, bracket openings, bollard openings) into a single unified component. This merging reduces the total number of separate parts and simplifies assembly procedures.
Solution Approach 2:
The closure component serves multiple functions simultaneously: it covers cable openings, attaches brackets, connects to bollards, and provides structural closure. This multi-functionality reduces device complexity by eliminating the need for separate components for each function, while the standardized opening patterns maintain ease of manufacture across different barrier configurations.

AI summary
A barrier is formed from bollards and posts that are embedded in a terrain. The bollards and posts are interconnected by, and support, vertically-spaced runs of primary rails. The rails in each run are aligned in end-to-end relationship. A strengthening cable extends within each run, and is anchored at each end within a concrete-filled bollard. Each bollard contains an elongate, vertically-oriented cable entry port that can receive the end portions of all of the cables in the runs, disposed in laterally-spaced relationship. A two-part closure covers the cable entry port, and includes spaced cable openings that maintain the cables that exit the bollard at a desired lateral separation distance. A cable confinement bracket installed at each post prevents the cables from flying out of the primary rails after an impact. The bracket features a spine that restrains the cables, which pass through bays notched in the spine's lower edge. Each cable may include attached cable clips to enhance the cable's resistance to pullout from the bollards.
