Cable Tray Spacer Structure for Multi-Layer Optical Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable laying trays struggle to accommodate a sufficient number of optical branch cables due to space constraints, leading to potential pressing of branch cord portions and inefficient cable arrangement.
Innovation Solution
A spacer structure with multiple support and holding plate portions that allows optical branch cables to be arranged in multiple layers, with strategically designed distances and passages to prevent pressing and enhance stability, enabling increased cable capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If optical branch cables are arranged in a single layer on the cable laying tray, then the arrangement is simple, but the number of cables that can be accommodated is limited
Solution Approach 1:
The patent transitions from single-layer to multi-layer cable arrangement by introducing vertical spacing through the spacer structure. The spacer includes a first holding plate portion and a second holding plate portion positioned at different heights, enabling cables to be arranged in multiple layers vertically, thereby increasing the number of cables that can be accommodated on the same cable laying tray.
2Quantity of substance
If cables are densely arranged to increase capacity, then space utilization improves, but branch cord portions may be pressed or damaged
Solution Approach 1:
The spacer acts as an intermediary structure between cables in different layers. It includes passage portions that guide and protect branch cord portions, preventing them from being pressed or damaged by cables in upper layers. The spacer structure provides physical separation and protection while enabling dense multi-layer arrangement.
3Quantity of substance
If multiple layers of cables are arranged, then cable capacity increases, but the structure becomes more complex
Solution Approach 1:
The spacer structure is segmented into distinct functional portions: first and second holding plate portions for supporting cables at different heights, support portions for engagement with the cable laying tray, and passage portions for guiding branch cords. This segmentation allows the complex multi-layer arrangement to be achieved through a modular, organized structure that manages complexity systematically.

AI summary
A spacer includes a first support portion, a second support portion, and a first holding plate portion. The first support portion and the second support portion are capable of being engaged with a vertically rising portion of a cable laying tray to support the spacer, and are capable of being engaged with the vertically rising portion at different positions in a first direction. The first holding plate portion is connected to the first support portion and the second support portion, and extends in parallel with a bottom portion when the first support portion and the second support portion are engaged with the vertically rising portion. A distance between the bottom portion and the first holding plate portion is larger than a distance obtained by totaling a diameter of a main cable and a diameter of a branch cord portion.
