Solar Cell Panel Fixing Member for Curved Vehicle Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solar cell panels applied to vehicles require a fixing solution that maintains a good appearance while preventing moisture penetration and ensuring reliable alignment of solar cells and wiring, especially when curved shapes are involved, as existing solutions like fixing tapes are not suitable for aesthetic and structural integrity.
Innovation Solution
A solar cell panel design featuring a sealing member surrounded by a fixing member with a melting type adhesive, which includes a base member and an adhesive layer, is used to securely attach the solar cell and wiring members to a cover member, ensuring no gaps for moisture prevention and maintaining a sleek appearance by being integrated within the sealing member during lamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixing tape is used to fix solar cells and sealing members, then the solar cells are secured at desired locations, but the fixing tape is easily recognized from the outside and harms the appearance, and may cause moisture penetration
Solution Approach 1:
The patent merges the fixing member and sealing member into a single integrated component. The fixing member includes both a sealing portion that seals the solar cell and a fixing portion that secures the solar cell to the substrate, eliminating the need for separate fixing tape and thus resolving the appearance issue while maintaining fixing reliability
Solution Approach 2:
The fixing member is designed to perform multiple functions simultaneously: it acts as both a sealing element (preventing moisture penetration) and a fixing element (securing solar cells at desired locations). This multi-functionality eliminates the need for separate components that would compromise appearance
2Manufacturing precision
If a fixing member is used to maintain distance between solar cells on a curved surface, then alignment is maintained, but the fixing member should not be easily recognized from the outside and must prevent moisture penetration
Solution Approach 1:
The fixing member combines sealing and fixing functions in one component, reducing structural complexity while maintaining alignment precision on curved surfaces
Solution Approach 2:
The fixing member has different functional zones: a sealing portion for moisture prevention and a fixing portion for alignment maintenance. This local differentiation allows the single component to address multiple requirements without increasing overall complexity
3Shape
If the solar cell panel has a curved shape for vehicle application, then aesthetic appearance is improved, but locations of various layers may change undesirably and moisture penetration risk increases
Solution Approach 1:
The fixing member is designed as a flexible component that can conform to curved surfaces while maintaining its sealing and fixing functions. This flexibility allows the panel to have aesthetic curved shapes without compromising sealing reliability or causing layer misalignment
