Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current racking systems for solar modules lack effective and standardized wire management solutions, particularly for free-air conductors, which are exposed to harsh environmental conditions and pose safety risks due to lack of predictable and labor-efficient methods for securing and routing electrical connections.
Innovation Solution
A framed photovoltaic module racking system with North-South and East-West oriented sub-assemblies featuring open-air channels and key connectors that form an integrated electrical raceway, allowing for secure and flexible routing of wires within the solar module array, reducing the need for additional hardware and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If free-air conductor management is implemented without standardized solutions, then installation flexibility is maintained, but safety and reliability deteriorate due to exposure to harsh environmental conditions
Solution Approach 1:
The patent combines wire management functionality directly into the racking system structure by integrating channels and raceways into the mounting structures themselves. This merging eliminates the need for separate wire management components while providing standardized, protected pathways for conductors, thereby improving reliability without sacrificing installation flexibility.
Solution Approach 2:
The racking system structures are designed to serve multiple functions: mechanical support for solar modules and integrated wire management for electrical conductors. The mounting structures include built-in channels and raceways that provide standardized pathways for conductor routing, protecting wires from environmental damage while maintaining adaptability for various installation configurations.
2Reliability
If additional hardware is used for wire management, then conductor protection is improved, but device complexity and installation labor increase
Solution Approach 1:
The patent eliminates the need for separate wire management hardware by integrating channels and raceways directly into the racking system mounting structures. This consolidation provides conductor protection through the structural elements already present in the system, reducing overall hardware complexity while maintaining reliable wire management.
3Ease of operation
If conventional wire management methods are used, then installation simplicity is maintained, but labor efficiency and predictability worsen due to lack of standardization
Solution Approach 1:
The integrated racking system provides standardized wire management pathways that work across different installation scenarios. The built-in channels and raceways offer consistent, predictable routing options for conductors, improving labor efficiency through standardization while maintaining ease of operation with straightforward installation procedures.
4Device complexity
If conductors are secured to module frames and support rails, then wire management is simplified, but adaptability deteriorates when modules lack frames or rails are misaligned
Solution Approach 1:
The patent integrates wire management channels and raceways into the racking system mounting structures themselves, creating a universal solution that does not depend on module frames or rail alignment. This approach provides standardized conductor pathways that work with various module types and configurations, maintaining both simplicity and adaptability.
