Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple single-line laser devices are integrated to improve obstacle detection accuracy, then detection precision improves, but device complexity and cost increase
Solution Approach 1:
The patent merges multiple laser light sources (N≥2) onto a single substrate, integrating what would traditionally require separate devices into one unified structure. This combining approach maintains the multi-line laser capability for improved obstacle detection accuracy while reducing overall device complexity by eliminating the need for multiple separate laser assemblies
Solution Approach 2:
The substrate serves as a universal platform that simultaneously supports multiple laser light sources, collimating components, and shaping components. This multi-functional integration allows the single device to perform the obstacle detection functions of multiple separate laser devices while reducing system complexity
2Reliability
If multiple single-line laser devices are integrated to eliminate blind zones, then reliability improves, but cost increases
Solution Approach 1:
By combining multiple laser light sources and their associated optical components onto a single substrate, the patent creates a unified multi-line laser device that eliminates blind zones for improved reliability. This integration reduces manufacturing cost by simplifying the assembly process and reducing the total number of separate components that need to be manufactured and assembled
3Measurement precision
If traditional multi-device integration is used to achieve multi-line laser, then obstacle detection capability improves, but size increases
Solution Approach 1:
The patent employs a nested structure where multiple laser light sources, collimating components, and shaping components are integrated within a single substrate and housing. This nesting approach allows the multi-line laser functionality to be achieved within a compact form factor, reducing the overall device size compared to traditional multi-device integration while maintaining obstacle detection capability
