Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mining machine travels in a mine without a predetermined traveling path, then the machine can adapt to varying mineral ore extraction progress, but it becomes difficult to determine and assess the actual traveling path for productivity improvement
Solution Approach 1:
The patent uses GPS positional information to create a digital copy of the actual traveling path. The traveling path calculating unit generates reference traveling path information that replicates the actual path taken by the mining machine, enabling path assessment without physical markers or predetermined routes
Solution Approach 2:
The patent replaces traditional mechanical path marking systems with wireless communication and GPS-based positional information detection. Instead of physical path indicators, the system uses electronic data transmission to capture, store, and analyze traveling path information
2Measurement precision
If positional information is collected continuously to determine accurate traveling paths, then path determination accuracy improves, but information processing complexity and storage requirements increase
Solution Approach 1:
The patent extracts only the essential positional information needed for path determination from the continuous data stream. The traveling path calculating unit processes GPS coordinates to generate reference traveling path information, filtering out redundant data while maintaining path accuracy
Solution Approach 2:
The system performs preliminary processing of positional information by generating reference traveling path information in advance. This pre-processed data can be stored and reused for multiple assessments, reducing the need for real-time complex processing
