Solution Overview

Problem

Existing cable management systems in solar energy systems fail to adequately protect and guide electric cables, leading to potential malfunction, damage, and electrical contact with metal support structures, which can compromise system performance and safety.

Innovation Solution

A device comprising a coupling element and a housing made of insulating material, with a guiding surface extending from both sides of a support structure, providing a protective barrier and guiding electric cables away from metal structures, featuring rounded side walls and an access opening for easy cable insertion, and optionally using hook-shaped fastening members for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cables are directly exposed to metal support structures, then installation is simpler, but electrical contact and system safety are compromised

Engineering Contradiction:
Improvesystem safetyVSAvoidcable management system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an insulating device as an intermediary component between the metal support structure and the electric cable. This device includes a housing made of insulating material with a receiving space that accommodates the cable, and a guiding surface that extends from the support structure to guide the cable away from the metal surface, preventing electrical contact while maintaining system safety.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The cable management system is divided into distinct functional components: a coupling element for attachment to the support structure, a housing with receiving space for cable accommodation, and a guiding surface for cable direction. This segmentation allows each component to perform its specific function effectively while contributing to the overall safety and organization of the cable management system.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If cables are allowed to bend freely, then cable routing is more flexible, but cable malfunction and damage increase

Engineering Contradiction:
Improvecable routing flexibilityVSAvoidcable functioning
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The guiding surface is designed to preliminarily direct the cable along a predetermined path away from the support structure before the cable is fully installed. This preliminary action ensures that the cable is properly positioned and guided from the beginning, preventing excessive bending and kinking that could lead to malfunction, while still allowing necessary routing flexibility.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If insulating material is used for the housing, then electrical protection is improved, but thermal insulation may reduce heat dissipation

Engineering Contradiction:
Improveelectrical protectionVSAvoidheat dissipation
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The housing is made of insulating material specifically at the portions that require electrical protection (the walls and guiding surface in contact with or near the cable). The design allows for localized thermal management by ensuring that the insulating material is applied where electrical isolation is critical, while the overall structure maintains adequate heat dissipation pathways for the cable system.

Inventive Principle:
Principle #3Local quality
