Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 2D barcode positioning method is adopted, then positioning function is achieved, but positioning costs increase due to requiring multiple 2D barcodes arranged in the environment
Solution Approach 1:
The patent replaces the 2D barcode positioning system with a 3D laser radar-based positioning system. Instead of using optical 2D barcodes that require environmental markers, the invention uses 3D laser radars to scan and acquire point cloud data of the environment, enabling positioning through spatial feature recognition without mechanical barcode markers.
Solution Approach 2:
The handling device performs self-positioning by using its own 3D laser radars to scan environmental features and determine its pose. The system does not rely on externally deployed 2D barcodes but instead uses the device's own sensing capabilities to acquire and process point cloud data for autonomous positioning.
2Measurement precision
If multiple 3D laser radars are arranged on the vehicle body to acquire data in multiple orientations, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The positioning system is segmented into multiple 3D laser radars positioned at different locations and orientations on the vehicle body. Each radar independently scans environmental features in its specific orientation (front, side, or rear), and the controller integrates these segmented point cloud datasets to achieve comprehensive and precise positioning.
Solution Approach 2:
The 3D laser radars serve multiple functions: they scan environmental features for positioning, provide data for pose determination, and enable the system to operate effectively in various orientations. This multi-functionality reduces the need for separate sensing systems for different scanning directions.
