Wire Jig Support Layout for Precise Solar Cell Tabbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tabbing apparatuses for solar cells face issues with wire displacement and poor connection due to uniform wire support configurations, leading to inefficient wire support and connection challenges during the solar cell module formation process.
Innovation Solution
A wire jig with a body frame and multiple supporting frames arranged in a specific pattern, featuring varying numbers and arrangements of supporting elements with contact members, is designed to securely support wires, preventing displacement and ensuring proper connection between solar cells and wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If uniform wire support configuration is used, then device complexity is reduced, but wire support efficiency and connection reliability deteriorate
Solution Approach 1:
The patent applies local quality by varying the number and arrangement of supporting elements in different supporting frames. Specifically, some supporting frames have a greater number of supporting elements while others have fewer, depending on the local wire layout requirements. This allows the wire support structure to adapt to different wire configurations at different locations, improving connection reliability without requiring a uniformly complex structure throughout.
Solution Approach 2:
The wire support structure is divided into multiple independent supporting frames, each capable of having different numbers and arrangements of supporting elements. This segmentation allows each frame to be optimized independently for its specific location and wire configuration, resolving the contradiction between overall device complexity and local connection reliability.
2Ease of manufacture
If fixed number and arrangement of supporting elements is used, then manufacturing simplicity is improved, but wire support adaptability deteriorates
Solution Approach 1:
The patent implements dynamics by making the number and arrangement of supporting elements variable across different supporting frames rather than fixed. Each supporting frame can be configured with appropriate numbers and arrangements of supporting elements based on the specific wire layout requirements at that location, allowing the structure to adapt dynamically to different wire configurations while maintaining manufacturing simplicity through modular design.
3Device complexity
If supporting elements are arranged in same pattern, then device complexity is reduced, but wire connection precision deteriorates
Solution Approach 1:
The patent applies asymmetry by deliberately arranging supporting elements in different patterns in different supporting frames. Rather than using a symmetric, uniform pattern throughout, the supporting frames have asymmetric configurations tailored to their specific locations and wire arrangements. This improves wire connection precision by matching the support pattern to the actual wire layout, while the modular nature of the supporting frames keeps the overall device complexity manageable.
