Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame systems for solar cell modules require complex screw-based installation processes and often necessitate the use of quadrangular frames around the entire edge area, increasing installation time and costs.
Innovation Solution
A frame system comprising a first frame member with a male coupling portion and a second frame member with a female coupling portion, featuring inclined surfaces and separation prevention surfaces, allowing for adhesive fixation and simplified alignment for easy installation without a quadrangular frame, using materials like aluminum alloys and two-part silicon adhesives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a quadrangular frame is installed around the entire edge area of the solar cell module, then the structural stability and fixation reliability are improved, but the material costs and installation complexity increase
Solution Approach 1:
The frame structure is segmented from a complete quadrangular frame into discrete frame members positioned only at corners or specific locations. Each frame member is equipped with coupling portions that provide fixation functionality without requiring continuous framing around the entire module edge, thus reducing material usage and installation complexity while maintaining structural reliability.
Solution Approach 2:
The invention extracts and eliminates the unnecessary quadrangular frame structure from the solar cell module installation system. By removing the requirement for a complete peripheral frame and retaining only essential frame members with coupling portions, the system achieves fixation reliability with reduced complexity and material costs.
2Strength
If screw-based installation processes are used for frame systems, then the fixation strength is improved, but the installation time and operational complexity increase
Solution Approach 1:
The invention replaces the screw-based mechanical fastening system with a coupling portion system that enables tool-free or simplified connection. The coupling portions are designed to provide adequate fixation strength through geometric interlocking and adhesive bonding, eliminating the need for screws and significantly reducing installation time and operational complexity.
Solution Approach 2:
The frame members are designed with self-aligning coupling portions that facilitate easy connection without requiring precision alignment tools or complex installation procedures. The coupling portions inherently guide the connection process and provide self-servicing capability, reducing installation time while maintaining fixation strength.
3Strength
If a quadrangular frame is used around the entire edge area, then the structural support is improved, but the material costs increase
Solution Approach 1:
The continuous quadrangular frame is segmented into discrete frame members positioned only where structurally necessary. This segmentation reduces the total quantity of framing material required while maintaining structural support functionality through strategically placed members with coupling portions.
Solution Approach 2:
The invention applies frame members with enhanced coupling portions only at specific locations where structural support and fixation are most needed, rather than uniformly around the entire module edge. This local quality approach optimizes material usage by concentrating structural reinforcement where it provides maximum benefit, reducing overall material costs while maintaining structural integrity.
