Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional alignment methods are used for solar cell elements, then assembly accuracy can be maintained, but production throughput is reduced due to time-consuming alignment processes
Solution Approach 1:
The system performs preliminary detection of the solar cell element's position and orientation using detection devices before the transfer device picks up the element. This preliminary action allows the transfer device to pre-align itself, ensuring accurate placement without slowing down the production line.
Solution Approach 2:
The detection devices continuously provide feedback information about the solar cell element's position and orientation to the transfer device. This feedback loop enables real-time adjustments to maintain alignment accuracy while keeping the alignment process integrated within the production throughput.
2Manufacturing precision
If multiple detection devices are used to improve alignment precision, then manufacturing precision increases, but device complexity increases
Solution Approach 1:
The system combines multiple detection devices into a unified detection system that works together to provide comprehensive position and orientation information. By merging the detection functions and integrating them with the transfer device's control system, the patent achieves high alignment precision while managing system complexity through coordinated operation.
