Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple independent lasers are used to process workpieces from different angles, then even surface processing is achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple laser beams from a single laser source by using beam splitting optics and mirrors to direct the divided beams onto the workpiece from different angles. This merging approach achieves multi-angle processing capability while reducing device complexity and cost compared to using multiple independent lasers.
Solution Approach 2:
The patent segments a single laser beam into multiple beams using beam splitting optics, then directs each segment onto different areas of the workpiece. This segmentation allows one laser source to perform the function of multiple lasers, reducing system complexity while maintaining processing uniformity.
2Adaptability or versatility
If multiple independent lasers are positioned for different beam directions, then all-round irradiation is achieved, but adjustment effort for different workpiece geometries increases
Solution Approach 1:
The patent creates a universal processing system where a single laser source with beam splitting and mirror arrangement can handle various workpiece geometries. The system's multi-functional design allows it to adapt to different processing requirements without requiring repositioning of multiple independent lasers, as the beam division and direction control are integrated into one adaptable unit.
3Manufacturing precision
If multiple independent lasers are used, then focal length consistency is required for all lasers, but individual focusing increases complexity
Solution Approach 1:
The patent merges the focusing function into a single optical path from one laser source. Since all beam segments originate from the same laser and pass through coordinated optical elements, focal length consistency is inherently maintained without requiring individual focusing adjustment of multiple independent lasers.
