Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drilling parameters are adjusted in real-time based on particle size measurements, then borehole quality and drilling efficiency are improved, but device complexity increases due to additional sensors and control systems
Solution Approach 1:
The system implements feedback control by measuring particle size during drilling and using this information to automatically adjust drilling parameters. The control system receives particle size data from sensors and modifies drilling parameters in real-time to optimize drilling efficiency and borehole quality, creating a closed-loop control system that continuously adapts to changing drilling conditions.
Solution Approach 2:
The patent replaces manual parameter adjustment with automated electronic control systems. Instead of operators manually changing drilling parameters based on experience, the system uses electronic sensors to measure particle size and electronic controllers to automatically adjust parameters, substituting mechanical/manual operations with automated electro-mechanical systems.
2Manufacturing precision
If real-time particle size measurement and parameter adjustment is implemented, then rock drilling performance is optimized, but loss of time occurs due to continuous measurement and adjustment processes
Solution Approach 1:
The system maintains continuous drilling operation while simultaneously performing particle size measurement and parameter adjustment. Rather than stopping to measure or adjust parameters, the system continuously measures particle size during drilling and continuously adjusts parameters in real-time, ensuring the useful action of drilling continues without interruption throughout the process.
