Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If satellite-based positioning systems are used for mobile mine work machines, then positioning capability is provided, but accurate positioning cannot be achieved in areas with obscured satellite views or poor signal quality
Solution Approach 1:
The system performs preliminary determination of satellite coverage conditions for multiple operational positions before executing mine work tasks. By using environmental models and satellite signal availability data, the system identifies suitable positions with adequate satellite coverage in advance, allowing operators to plan routes and tasks that avoid areas with poor positioning conditions.
Solution Approach 2:
The system introduces an intermediary layer between the satellite positioning system and the mine work machine operation. This intermediary system determines satellite coverage conditions, evaluates positioning quality, and provides guidance information to operators, effectively mediating the impact of satellite signal obstruction on positioning accuracy.
2Productivity
If mine work tasks are executed at designated positions, then production targets are met, but operational downtimes occur due to poor satellite positioning conditions
Solution Approach 1:
The system determines satellite coverage conditions for multiple operational positions in advance before mine work tasks are executed. By identifying positions with adequate satellite coverage beforehand, the system enables operators to plan efficient routes and task sequences that minimize or eliminate operational downtimes caused by poor positioning conditions.
Solution Approach 2:
The system provides dynamic guidance information that adapts to changing satellite coverage conditions. As satellites move and coverage conditions change over time, the system updates its assessments and provides real-time recommendations for adjusting operational positions and routes to maintain optimal positioning accuracy.
3Ease of operation
If operators work without satellite coverage assistance, then simple operation is maintained, but less skilled operators require more intervention and efficiency is reduced
Solution Approach 1:
The system provides self-service functionality by automatically determining satellite coverage conditions and generating guidance information without requiring complex operator intervention. The system independently evaluates positioning conditions at different operational positions and provides ready-to-use recommendations, making the operation easier while maintaining high reliability.
Solution Approach 2:
The system implements feedback by providing operators with information about satellite coverage conditions at various operational positions. This feedback enables operators to make informed decisions about route selection and position changes, improving operational efficiency without requiring advanced skills or extensive intervention.
