Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If laser light irradiation points are scanned rotationally in a circular form, then coating on surface can be removed, but variation in processing state according to site and processing inconsistency occur
Solution Approach 1:
The patent divides the single laser beam into multiple beams (e.g., 3-5 beams) that irradiate different points on the surface simultaneously. This segmentation allows parallel processing of multiple areas, improving productivity while maintaining consistent processing quality across different sites by distributing the processing load across multiple beam paths.
Solution Approach 2:
The patent introduces a moving mechanism that dynamically adjusts the positions of multiple mirrors or beam splitters to change the irradiation pattern. This dynamic adjustment enables the system to adapt to different processing requirements and maintain consistent processing quality across various sites by optimizing beam distribution in real-time.
2Device complexity
If a single laser beam is used for surface processing, then device structure is simple, but processing uniformity across different sites is poor
Solution Approach 1:
The patent employs beam splitting optics to divide a single laser beam into multiple beams that irradiate different surface locations simultaneously. This segmentation approach maintains processing uniformity across different sites while avoiding the need for multiple independent laser sources, thus controlling device complexity.
Solution Approach 2:
The patent uses optical elements such as beam splitters, mirrors, and optical fibers as intermediaries to distribute the laser energy to multiple processing points. These intermediary components enable uniform processing across different sites while keeping the system relatively simple by using standard optical components rather than complex multi-source configurations.
