Aerial Optical Cable Termination Box Support to Bypass Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical cable termination boxes are prone to damage due to the direct transfer of load from aerially suspended drop cables, which can strain or damage the box, especially under weather conditions or when technicians are working nearby, and there are additional fees associated with affixing structures to utility poles.
Innovation Solution
A support system for aerially suspending optical cable termination boxes, which includes a body to support the weight of the box, a first coupler to attach to a structure, and a second coupler to the drop cable, allowing the load to bypass the termination box and be transferred to the support, thereby reducing strain on the box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the drop cable is directly connected to the optical cable termination box, then the cable routing is simplified, but the termination box is strained or damaged due to load transfer
Solution Approach 1:
A support structure acts as an intermediary element between the drop cable and the termination box. The support structure includes a first coupler that attaches to the utility pole and a second coupler that attaches to the drop cable, creating a load-bearing intermediary that prevents direct load transfer to the termination box while maintaining simplified cable routing.
2Ease of manufacture
If the termination box is affixed directly to the utility pole, then installation is straightforward, but additional fees are charged for affixing structures to utility poles
Solution Approach 1:
The support structure serves as a mediator that attaches to the utility pole through the first coupler, while the termination box attaches to the support structure rather than directly to the pole. This intermediary arrangement maintains installation simplicity while avoiding direct affixing fees charged by utility companies.
3Device complexity
If the termination box supports the drop cable load directly, then the support structure is simplified, but the box is damaged under weather conditions or external forces
Solution Approach 1:
The support system is segmented into distinct functional components: a first coupler for attaching to the utility pole, a support structure body, a second coupler for attaching to the drop cable, and the termination box. This segmentation allows the load-bearing functions to be separated from the termination box, protecting it from damage while maintaining overall system simplicity.
4Device complexity
If the load of the drop cable is transferred to the termination box, then the support structure is minimized, but the box is strained when load shifts or increases due to weather or external objects
Solution Approach 1:
The support structure functions as a load-bearing intermediary that absorbs and manages variable loads from the drop cable, including those caused by weather conditions or external objects. This intermediary protects the termination box from strain while maintaining a relatively simple overall support structure.
