Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual optical transmission paths are provided for each scanning position, then accurate simulation of LiDAR performance is achieved, but device complexity and manufacturing costs increase significantly
Solution Approach 1:
The patent merges the functions of collecting laser light from multiple scanning positions and emitting false light back to the LiDAR into a single integrated condenser unit. This eliminates the need for separate optical transmission paths for each scanning position, thereby simplifying the device configuration while maintaining simulation accuracy.
Solution Approach 2:
The condenser unit is designed to perform multiple functions: it collects laser light from all scanning positions, guides the collected light to the simulator, and emits the generated false light back to the LiDAR. This multi-functional design replaces the need for multiple dedicated optical paths, reducing device complexity.
2Measurement precision
If individual optical transmission paths are provided for each scanning position, then accurate simulation of LiDAR performance is achieved, but manufacturing and maintenance costs increase
Solution Approach 1:
By combining the optical path functions into a single condenser unit, the patent reduces the total number of optical components that need to be manufactured and assembled. This merging approach significantly lowers manufacturing costs while preserving the ability to accurately simulate LiDAR performance across all scanning positions.
3Measurement precision
If individual optical transmission paths are provided for each scanning position, then accurate simulation of LiDAR performance is achieved, but maintenance costs and difficulty increase
Solution Approach 1:
The patent merges multiple optical transmission functions into a single condenser unit, which simplifies the overall system architecture. This reduction in the number of separate optical paths makes the system easier to maintain and repair, as there are fewer components that can fail and less complex routing to troubleshoot.
