Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual path correction method is used, then manufacturing precision can be ensured, but loss of time and productivity decrease significantly
Solution Approach 1:
The system performs self-correction by automatically comparing real-time tool coordinates with predetermined path coordinates and amending the movement path based on detected deviations, eliminating the need for manual path correction while maintaining manufacturing precision
Solution Approach 2:
The detector continuously monitors the tool's real-time position and feeds this information back to the processing device, which then automatically adjusts the movement path to maintain accuracy within allowable errors, resolving the contradiction between precision and time consumption
2Manufacturing precision
If manual path correction is performed, then path accuracy can be maintained, but productivity is reduced due to repeated manual operations
Solution Approach 1:
The patent replaces manual mechanical operations with an automated system comprising a detector, processing device, and driver that automatically monitor, calculate deviations, and adjust the tool's movement path, thereby maintaining coordinate accuracy while significantly improving processing efficiency
Solution Approach 2:
The system autonomously performs path verification and correction by comparing real-time coordinates with predetermined coordinates and automatically amending deviations, eliminating repetitive manual operations and enhancing productivity without sacrificing precision
3Manufacturing precision
If virtual path with auxiliary points is used, then manufacturing precision improves, but device complexity increases
Solution Approach 1:
The virtual path is segmented into multiple sections with predetermined points and auxiliary points, allowing the system to monitor and correct deviations at multiple locations along the path, thereby improving manufacturing precision through structured division of the movement trajectory
Solution Approach 2:
The processing device acts as an intermediary that receives detection data from the detector, calculates coordinate deviations, and sends correction commands to the driver, coordinating multiple system components to achieve precise path following while managing overall system complexity through centralized control
