Solar Cell Module Frame Structure for Moisture-Resistant Coupling

Solution Overview

Problem

Existing solar cell modules face moisture infiltration issues when frames are coupled, leading to mechanical instability and increased coupling costs due to the need for frames to be inclined.

Innovation Solution

The solar cell module design includes a fourth sub-frame that allows frames to couple in a parallel configuration, maintaining a horizontal state and preventing moisture infiltration, thereby enhancing stability and reducing assembly complexity.

If frames are inclined at a predetermined angle to prevent moisture infiltration, then moisture resistance is improved, but mechanical stability deteriorates and coupling cost increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The frame is divided into multiple sub-frames (first, second, third, and fourth sub-frames) that can be independently configured. The first and third sub-frames extend in one direction while the second and fourth sub-frames extend in another direction, creating a segmented structure that provides both moisture resistance through proper spacing and mechanical stability through the distributed framework

Inventive Principle:

Solution Approach 2:

The patent introduces a multi-dimensional frame configuration where sub-frames extend in different directions (first direction and second direction perpendicular to the first). This dimensional arrangement allows the frame to maintain horizontal alignment for stability while creating overlapping regions that prevent moisture infiltration

Solution Approach 1:

The frame is divided into multiple sub-frames (first, second, third, and fourth sub-frames) that can be independently configured. The first and third sub-frames extend in one direction while the second and fourth sub-frames extend in another direction, creating a segmented structure that provides both moisture resistance through proper spacing and mechanical stability through the distributed framework

Solution Approach 2:

The sub-frames serve multiple functions simultaneously: the first and third sub-frames provide primary structural support, while the second and fourth sub-frames create the overlapping configuration for moisture resistance. This multi-functionality reduces overall device complexity by combining support and protection functions into a unified structure
