Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If full three-dimensional models are used for route planning and positioning, then positioning accuracy and route planning capability are improved, but computational resource consumption and system complexity increase significantly
Solution Approach 1:
The patent extracts only the floor surface points from the complete three-dimensional point cloud model of the underground tunnel. By separating and utilizing only the relevant floor points rather than the entire 3D model, the system achieves effective positioning and route planning while significantly reducing computational complexity and resource consumption.
Solution Approach 2:
The patent segments the three-dimensional point cloud data by identifying and separating floor points from other elements (walls, ceiling, equipment). This segmentation allows the system to work with a simplified subset of data that contains only the necessary information for mobile object positioning and route planning on the tunnel floor.
2Manufacturing precision
If full three-dimensional models are used for route planning, then route calculation accuracy is improved, but computational processing time and energy consumption increase
Solution Approach 1:
The system extracts only floor-relevant points from the complete 3D model, creating a simplified floor model that retains all necessary information for accurate route calculation while eliminating unnecessary data. This extraction process significantly reduces computational processing time and energy consumption compared to using the full three-dimensional model.
3Loss of information
If detailed three-dimensional models are maintained, then environmental representation completeness is improved, but data processing complexity and storage requirements increase
Solution Approach 1:
The patent extracts floor points from the complete environmental model while preserving all necessary spatial and geometric information needed for positioning and navigation. This selective extraction maintains environmental representation completeness for floor-related operations without the complexity of processing the entire three-dimensional environmental data.
