Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If simple surface markings and pre-designed tunnel lines are used for navigation, then the navigation system is simple to implement, but the adjustability and data monitoring capability are insufficient
Solution Approach 1:
The navigation system transitions from static pre-designed tunnel lines to dynamic real-time navigation. The apparatus continuously determines the rock drilling rig's position and direction relative to previously excavated rounds, dynamically adjusting the tunnel line based on actual excavation progress and conditions, thereby improving adaptability while maintaining manageable complexity through automated real-time processing.
Solution Approach 2:
The system implements feedback by continuously monitoring the rock drilling rig's position and direction during excavation, comparing actual progress with the planned tunnel line, and automatically adjusting navigation instructions. This closed-loop feedback mechanism enables real-time adjustability without requiring complex manual intervention, resolving the contradiction between adaptability and system complexity.
2Loss of information
If pre-designed tunnel lines are used, then the planning process is straightforward, but the ability to provide useful monitoring data and analyze drilling specific data is limited
Solution Approach 1:
The navigation apparatus automatically collects, processes, and stores drilling-specific data including position, direction, and excavation progress without requiring external data gathering systems. The system self-generates comprehensive monitoring data by integrating sensor inputs and navigation information, thereby maximizing data utilization while avoiding the complexity of multiple separate data collection systems.
Solution Approach 2:
The system merges navigation functions with data collection and analysis functions into a single integrated apparatus. By combining the determination of rig position, tracking of excavation progress, and storage of drilling-specific data into one unified system, the patent achieves comprehensive data utilization without the complexity of multiple separate systems working in parallel.
3Measurement precision
If navigation is based on simple markings, then the system is easy to operate, but the precision and reliability of position determination is insufficient
Solution Approach 1:
The system replaces simple mechanical surface markings with an electronic navigation apparatus that uses sensor-based position determination. The apparatus employs electronic sensors and data processing to accurately determine the rock drilling rig's position and direction relative to previously excavated rounds, achieving high measurement precision while maintaining ease of operation through automated electronic control rather than manual marking interpretation.
4Adaptability or versatility
If the tunnel line is predetermined in the office, then the planning is efficient, but the flexibility to adapt to actual excavation conditions is reduced
Solution Approach 1:
The navigation apparatus operates continuously throughout the excavation process, constantly determining the rig's position, comparing it with the planned tunnel line, and providing real-time navigation adjustments. This continuous operation eliminates interruptions and delays associated with periodic re-planning, enabling the system to adapt flexibly to actual excavation conditions in real-time without losing productivity or time.

AI summary
An apparatus, rock drilling rig, method and computer program for executing navigation for a rock drilling rig in a mine tunnel. The rock drilling rig is positioned at faces of rounds and is navigated before initiating drilling. The navigation is executed without a predetermined tunnel line. The realized tunnel line is formed by combining navigation data on several rounds. Length and direction of the round to be drilled next may be adjusted according to need.
