Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single beam of laser is used for scribing, then the device complexity is low, but the scribing depth consistency deteriorates and scribing efficiency is low
Solution Approach 1:
The patent divides a single laser beam into multiple separate beams using beam splitters. Each beam is independently directed to scribe at different depths or positions, allowing precise control over scribing depth consistency while maintaining relatively simple device architecture through optical component segmentation.
2Device complexity
If a single beam of laser is used for scribing, then the device structure is simple, but the scribing efficiency deteriorates
Solution Approach 1:
By segmenting the laser beam into multiple parallel beams that can scribe simultaneously or in rapid sequence, the system achieves higher productivity without significantly complicating the overall device structure, as the beam splitting is accomplished through optical components rather than mechanical systems.
Solution Approach 2:
The patent combines multiple laser beams into a unified scribing system that operates from a single laser source. This merging approach allows multiple scribing operations to be performed using one laser device, improving efficiency while avoiding the complexity of coordinating multiple independent laser systems.
3Manufacturing precision
If laser energy is increased to achieve deeper scribing, then the scribing depth improves, but the energy fluctuation increases导致scribing consistency deteriorates
Solution Approach 1:
The total laser energy required for deep scribing is segmented across multiple beams, each carrying a portion of the total energy. This distribution prevents excessive energy concentration that would cause fluctuations, while still achieving the required cumulative scribing depth through coordinated action of multiple beams.
