Crossover-bridge cable router prevents electromagnetic interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable trays often experience electrical or other interference due to contact between different types of cables, particularly between fiber optic and copper or aluminum cables, which can lead to performance issues and reliability problems.
Innovation Solution
A crossover-bridge cable router with a horizontal floor and multiple downward ramps, including at least two ramps positioned parallel or perpendicular to each other, and optionally additional ramps, which securely route cables to avoid contact by allowing fiber optic cables to run over other cables, minimizing physical contact and electromagnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cables are routed through intersecting cable trays, then cable installation flexibility is improved, but electrical interference between different cable types occurs
Solution Approach 1:
The cable routing path is segmented into separate elevation levels using the crossover-bridge structure. Fiber optic cables are routed on the upper level while copper/aluminum cables remain on the lower level, physically dividing the cable types to eliminate electrical interference while preserving installation flexibility
Solution Approach 2:
The invention introduces a vertical dimension to the cable routing problem by creating an elevated crossover-bridge structure. This allows cables to be routed in three-dimensional space rather than constrained to a single planar level, enabling fiber optic cables to cross over copper cables without contact
2Device complexity
If fiber optic cables come into contact with copper or aluminum cables, then cable routing simplicity is improved, but electromagnetic interference occurs
Solution Approach 1:
The crossover-bridge structure serves as an intermediary element that facilitates cable crossing without direct contact. It provides a mediating platform that allows fiber optic cables to transition from one cable tray to another while maintaining physical separation from copper or aluminum cables, thus preventing electromagnetic interference
Solution Approach 2:
The cable routing system uses asymmetric elevation positioning where fiber optic cables are consistently routed on the upper level of the crossover-bridge while copper/aluminum cables remain on the lower level. This asymmetric arrangement ensures physical separation and prevents electromagnetic interference while maintaining routing simplicity

AI summary
Crossover-bridge cable routers for routing cables through intersections and/or around corners of cable trays are described herein. The crossover-bridge cable router may include a floor, at least a portion of which is substantially horizontal, and at least two ramps, wherein each ramp extends downward from a side of the floor and is positioned either parallel or perpendicular to the other (i.e., opposing or adjacent) ramp.
