Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management solutions for solar power plants do not adequately address the heating effects caused by adjacent cables, leading to cable derating and increased costs.
Innovation Solution
A cable hanger system that suspends multiple pairs of electrical cables from a messenger wire in a spaced configuration, using a modular design with primary and secondary hangers, and carrier portions arranged in a spaced array to minimize heat buildup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cables are bundled closely together for efficient space utilization, then cable management efficiency is improved, but heat buildup increases causing cable derating and requiring larger, more expensive cables
Solution Approach 1:
The cable management system segments cables into individual carrier portions arranged in spaced arrays, dividing the cable bundle into separated units that allow heat dissipation while maintaining organized management. Each carrier portion holds individual cables or cable pairs at spaced intervals rather than allowing them to bundle closely together.
Solution Approach 2:
The system transitions from horizontal/planar cable arrangement to a three-dimensional spaced array configuration suspended from messenger wires. Carrier portions are distributed in multiple rows and columns at vertical and horizontal spacing, utilizing spatial dimensionality to achieve both organization and heat dissipation.
2Reliability
If larger cables are used to compensate for heat-related power losses, then power transmission reliability is improved, but system cost increases
Solution Approach 1:
The system converts the harmful heat buildup effect into a beneficial outcome by using the spaced arrangement to improve heat dissipation. This eliminates the need for oversized cables, allowing standard cable sizes to be used while maintaining or improving power transmission reliability through better thermal management.
3Temperature
If cables are arranged in a spaced configuration to reduce heat buildup, then heat dissipation is improved, but cable management complexity increases
Solution Approach 1:
The system merges multiple functional elements into integrated carrier portions that combine cable support, spacing, and organizational features into single components. Multiple carrier portions are then merged into coordinated arrays suspended from messenger wires, creating a unified management system that achieves heat dissipation without proportionally increasing complexity.
Solution Approach 2:
The carrier portions and messenger wire system serve multiple functions simultaneously: they support cables, provide spaced arrangement for heat dissipation, organize cables in manageable arrays, and enable easy installation and maintenance. This multi-functionality reduces overall system complexity despite the spaced configuration.
