Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing machine tool control systems are used without modification, then the system structure remains simple and stable, but unmanned aerial vehicles cannot be integrated or controlled within the manufacturing environment
Solution Approach 1:
The numerical controller is enhanced to perform multiple functions: it continues to control machine tools while simultaneously acquiring, converting, and outputting move commands for unmanned aerial vehicles. This multi-functionality allows the existing control system to integrate UAV control without requiring a completely separate control system, thus improving adaptability while limiting complexity increase.
Solution Approach 2:
A coordinate system conversion unit is introduced as an intermediary component between the machine tool control coordinate system and the UAV control coordinate system. This converter acts as a mediator that translates commands between different coordinate systems, enabling UAV integration without requiring fundamental changes to the existing machine tool control architecture.
2Adaptability or versatility
If coordinate system conversion is implemented, then UAV control compatibility is improved, but the control process complexity increases
Solution Approach 1:
The numerical controller performs the coordinate system conversion automatically as part of its normal operation. The controller acquires move commands in its native coordinate system, automatically converts them to the UAV's coordinate system, and outputs the converted commands without requiring external intervention. This self-service approach handles the conversion complexity internally while maintaining a simple external interface.
3Adaptability or versatility
If UAVs are integrated into the manufacturing floor, then operational flexibility and monitoring capabilities are enhanced, but coordination with existing machine tools becomes more difficult
Solution Approach 1:
The UAV control functionality is merged with the existing machine tool numerical controller rather than operating as a separate system. By combining UAV command acquisition, coordinate conversion, and output functions within the existing controller, the system achieves coordinated control of both machine tools and UAVs through a single integrated control platform, reducing overall coordination complexity.

AI summary
A numerical controller acquires a move command for an unmanned aerial vehicle in a coordinate system set in the numerical controller. The numerical controller converts a coordinate system of the move command into a coordinate system for controlling the unmanned aerial vehicle, and outputs the move command to the unmanned aerial vehicle.
