Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing solar modules are inefficient in achieving electrical interconnection and mechanical bonding of solar elements, leading to suboptimal electrical voltage distribution within the modules.
Innovation Solution
A method involving the use of an electrically conductive adhesive applied during the assembly of solar modules, allowing for both mechanical and electrical interconnection of rows of solar elements, with the adhesive being applied using a discharge unit that can be fixed or moved to ensure precise application, enabling efficient electrical voltage build-up transversely or at right angles to the rows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional adhesive application methods are used for bonding solar element rows, then mechanical interconnection is achieved, but electrical interconnection is not established and individual handling is required
Solution Approach 1:
The patent combines mechanical bonding and electrical interconnection into a single integrated process by using electrically conductive adhesive. The adhesive simultaneously performs both functions: bonding rows mechanically while establishing electrical contact between solar elements, eliminating the need for separate electrical connection steps and individual handling.
Solution Approach 2:
The electrically conductive adhesive serves multiple functions: it acts as a mechanical bonding agent for structural connection and as an electrical conductor for electrical interconnection. This multi-functional material replaces what would traditionally require separate adhesive and electrical connection systems.
2Productivity
If electrically conductive adhesive is applied during transfer movement, then simultaneous mechanical and electrical connection is achieved, but precise adhesive placement becomes more difficult
Solution Approach 1:
The adhesive application is performed during the transfer movement phase, before the rows are fully positioned in their final location. The discharge unit applies adhesive to the moving rows, and subsequent positioning occurs after adhesive application, allowing the system to leverage the existing transfer motion rather than requiring separate precise positioning operations.
Solution Approach 2:
The discharge unit acts as an intermediary that can operate independently of the precise positioning system. By applying adhesive during transfer movement, the system decouples the adhesive application function from the final positioning function, allowing each to be optimized separately.
3Device complexity
If discharge unit remains spatially fixed during discharge, then device complexity is reduced, but adhesive application flexibility is limited
Solution Approach 1:
The discharge unit is designed with dynamic positioning capability, allowing it to be adjusted in the vertical direction (z-axis) to modify the spacing between rows. This dynamic adjustment mechanism enables the fixed horizontal position to be complemented by vertical flexibility, accommodating different row configurations without requiring complex multi-axis movement.
