Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the LiDAR system uses traditional separate-plane configuration for rotating mirror and galvanometer, then the scanning performance is maintained, but the structural size becomes large
Solution Approach 1:
The patent merges the rotating mirror and galvanometer into the same plane, combining two previously separate scanning components into a unified planar structure. This integration reduces the overall volume while maintaining the independent scanning functions of both components, directly resolving the contradiction between compact size and scanning performance.
Solution Approach 2:
The patent transitions from a three-dimensional stacked arrangement to a two-dimensional planar configuration by placing both the rotating mirror and galvanometer in the same plane. This dimensional change optimizes space utilization and reduces the vertical height of the system while preserving the full scanning capability in both horizontal and vertical directions.
2Volume of moving object
If the LiDAR system reduces the space occupied by scanning components, then the overall system size decreases, but the scanning capability may be compromised
Solution Approach 1:
By merging the rotating mirror and galvanometer into the same plane, the system achieves compact space occupation while preserving the dual-axis scanning capability. The co-planar arrangement allows both components to function independently without interfering with each other's scanning ranges, maintaining full adaptability for environmental detection.
Solution Approach 2:
The planar configuration optimizes space usage by eliminating vertical stacking, thereby reducing the volume occupied by scanning components. Despite this space reduction, the system maintains comprehensive scanning capability across horizontal and vertical dimensions through the coordinated operation of both mirrors in the same plane.
3Volume of moving object
If the LiDAR system uses compact configuration, then the structural size is reduced, but the complexity of arranging components increases
Solution Approach 1:
The co-planar merging of rotating mirror and galvanometer simplifies the overall component arrangement by eliminating the need for vertical stacking and complex three-dimensional positioning. This unified planar structure reduces assembly complexity while achieving compact structural size, making the system easier to manufacture and maintain.
