Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management of electric conductors and fluid ducts in solar cogeneration systems is complex, leading to longer installation times and higher costs due to the need for precise positioning and avoidance of shading, which can result in incorrect connections and safety issues.
Innovation Solution
A composite flat cable design with two main electric conductors and at least two ducts for fluid circulation, arranged in a rectangular cross-section with the conductors at the ends and ducts alongside, surrounded by a flame-retardant outer sheath, optimizing installation and reducing shading effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate management of electric conductors and fluid ducts is used, then installation flexibility is maintained, but installation time increases and complexity increases
Solution Approach 1:
The patent combines electric conductors and fluid ducts into a single integrated flat cable assembly. The flat cable contains both electrical conductors and fluid circulation ducts in the same structure, eliminating the need to manage them separately during installation. This merging directly resolves the contradiction by improving installation productivity while reducing management complexity.
Solution Approach 2:
The flat cable serves multiple functions simultaneously: it provides both electrical power transmission and fluid transportation. This multi-functionality allows a single component to replace what would traditionally require separate management of multiple components, thereby speeding up installation and reducing complexity.
2Object-affected harmful factors
If traditional circular cable is used, then flexibility is good, but shading area increases
Solution Approach 1:
The patent employs a flat cable cross-section instead of a traditional circular one. This asymmetric shape reduces the cable's profile in one dimension, minimizing the shading area when the cable is installed on or near solar panels. The flat geometry allows the cable to be positioned with minimal obstruction to sunlight while maintaining installation flexibility.
Solution Approach 2:
The transition from a circular cross-section to a flat cross-section represents a dimensional change that optimizes the cable's spatial characteristics. By flattening the cable profile, the shading area is reduced in the dimension critical for solar radiation reception, while the cable retains flexibility for installation through its elongated form factor.
3Reliability
If precise positioning of conductors and tubes is required, then connection accuracy improves, but installation time increases
Solution Approach 1:
The flat cable is pre-assembled with electric conductors and fluid ducts positioned in their correct relative configurations during manufacturing. This preliminary action ensures that when the cable is installed, the components are already in their proper positions, eliminating the need for time-consuming on-site positioning adjustments while maintaining connection accuracy.
Solution Approach 2:
By integrating multiple conductors and ducts into a single flat cable assembly with fixed internal geometry, the patent ensures precise relative positioning is maintained throughout installation. The merged structure prevents misalignment issues that would arise from separate installation, thereby ensuring connection reliability without increasing installation time.
