Solution Overview
Problem
Existing solar cell modules lack sufficient weather-resistance, leading to potential deterioration from water accumulation and ingress.
Innovation Solution
A solar cell module design featuring a rectangular module main body surrounded by a frame with a groove and an adhesive member, where the frame includes angled sections and through holes in corner portions to facilitate water drainage, preventing water accumulation and enhancing sealing between the module and frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the frame is provided with a groove and adhesive member to seal the module main body, then the sealing performance is improved, but water accumulation may occur in corner portions leading to reduced weather-resistance
Solution Approach 1:
The patent extracts the harmful function of corner portions by removing the groove in corner regions and replacing it with through holes. This eliminates the water accumulation problem in corners while maintaining sealing performance in straight frame sections where the groove-adhesive member structure is preserved.
Solution Approach 2:
The patent introduces through holes in corner portions of the frame, creating a porous structure that allows water to drain out rather than accumulate. These through holes enable water passage while the adhesive member in straight sections maintains sealing, thus resolving the water accumulation issue without compromising overall sealing performance.
2Strength
If the adhesive member is provided throughout the entire frame groove, then the bonding strength is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent segments the frame into straight sections and corner portions, applying different structures to each. The adhesive member is provided only in straight frame sections, while corner portions use through holes for drainage. This segmentation reduces manufacturing complexity and adhesive material usage while maintaining sufficient bonding strength where needed.
Solution Approach 2:
The patent applies different structural qualities to different locations: straight frame sections have grooves with adhesive members for bonding, while corner portions have through holes for drainage. This local differentiation optimizes both bonding strength and manufacturing simplicity by avoiding unnecessary adhesive application in corner regions.
