Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual selection of drill rig position is used, then flexibility in operation is maintained, but positioning accuracy and drilling efficiency deteriorate
Solution Approach 1:
The system performs self-positioning by automatically calculating the optimal drill rig position based on tunnel geometry, drill plan, and vehicle dimensions. The automated positioning system selects the target position without human intervention, improving positioning accuracy while the modular architecture keeps system complexity manageable.
Solution Approach 2:
The patent replaces manual mechanical positioning with an automated computational system that uses processors to calculate optimal positions based on geometric data, drill plans, and predefined criteria. This substitution of manual operation with automated computation resolves the contradiction between positioning precision and system complexity.
2Productivity
If automated position selection is implemented, then drilling efficiency is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary calculations of the optimal drill rig position before drilling operations begin. By pre-determining the target position based on tunnel geometry, navigation plane, and vehicle characteristics, the system enables efficient drilling operations without requiring complex real-time adjustments during drilling.
Solution Approach 2:
The patent utilizes parameter changes in the computational model, including variations in tunnel geometry, drill plan parameters, and vehicle dimensions, to automatically determine the optimal position. This parametric approach improves drilling efficiency through automated adaptation while maintaining manageable system complexity through mathematical modeling.
3Measurement precision
If multiple position variations are evaluated, then positioning accuracy is improved, but computational time increases
Solution Approach 1:
The system evaluates multiple predefined position variations around the initial calculated position to ensure optimal selection. By considering several candidate positions with different offsets and orientations, the system achieves accurate position selection while limiting computational effort through the use of predefined variation patterns rather than exhaustive search.
