Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the diamond wire machine processes larger masses of rock to increase productivity, then the output increases, but maintaining constant tension and synchronization becomes more difficult
Solution Approach 1:
The patent implements a feedback control system using encoders on the traction wheel and arm actuators to continuously monitor position and tension. The controller receives signals from these encoders and automatically adjusts hydraulic cylinder extension to maintain constant diamond wire tension, enabling reliable operation during high-productivity processing of large rock masses
Solution Approach 2:
The system performs self-adjustment through automated feedback control without requiring manual intervention. The controller automatically compensates for tension variations and synchronization errors by adjusting actuator positions based on encoder feedback, allowing the machine to maintain reliability independently during extended high-productivity operation
2Productivity
If the diamond wire machine processes larger masses of rock to increase productivity, then the output increases, but synchronizing arm movements becomes more complex
Solution Approach 1:
The patent combines multiple control functions into a single integrated controller that manages traction wheel rotation, vertical arm movement, and horizontal arm positioning. This unified control system receives feedback from all encoders and coordinates all actuators simultaneously, simplifying the control architecture while enabling synchronized operation during high-productivity processing of large rock masses
3Manufacturing precision
If the tensioning is maintained constant throughout the cutting process, then the cutting quality improves, but the system requires more complex control mechanisms
Solution Approach 1:
The patent uses encoder feedback from the traction wheel and arm actuators to create a closed-loop control system. The controller continuously monitors actual positions and compares them with target positions, automatically adjusting hydraulic cylinder extension to maintain constant diamond wire tension throughout the cutting process, thereby ensuring high cutting quality without requiring overly complex manual control mechanisms
