Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional heat treatment or light treatment is applied separately to solar cells, then processing simplicity is maintained, but output loss occurs and efficiency is not maximized
Solution Approach 1:
The patent combines heat treatment and light treatment into a single integrated post-processing step by positioning both a heater and a light source to simultaneously treat the solar cell. This merging of previously separate processes enables synergistic effects that reduce output loss and maximize efficiency without requiring multiple sequential treatment steps.
2Productivity
If separate heat treatment and light treatment processes are used, then equipment simplicity is maintained, but processing effectiveness is reduced due to output losses
Solution Approach 1:
The apparatus integrates multiple treatment functions (heat treatment, light treatment, and drying) into a single post-processing unit. The heater, light source, and drying mechanism are combined in one system that processes solar cells through multiple stages simultaneously, improving processing effectiveness while maintaining reasonable device complexity through functional integration.
Solution Approach 2:
The post-processing apparatus performs multiple functions including heat treatment, light treatment, and drying within a single device. This multi-functionality allows the apparatus to address various processing needs (reducing output loss, removing solvent, preventing defects) without requiring separate equipment for each function.
3Manufacturing precision
If multiple separate treatment steps are applied to maximize efficiency, then treatment thoroughness is improved, but processing time increases
Solution Approach 1:
The patent merges heat treatment, light treatment, and drying steps into a single integrated process that occurs simultaneously. This eliminates the need for sequential processing of each treatment type, reducing total processing time while maintaining thorough treatment through the combined effects of multiple treatment modalities applied concurrently.
Solution Approach 2:
The apparatus maintains continuous useful action by performing heat treatment, light treatment, and drying simultaneously in an uninterrupted process. All three treatment functions operate continuously on the solar cell at the same time, eliminating idle time between steps and maximizing processing efficiency without sacrificing treatment thoroughness.
