Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual alignment is used for light sources, then alignment precision can be achieved, but realignment is time-consuming and limits industrialization
Solution Approach 1:
The system performs self-alignment through automated feedback control. The detection unit monitors beam position, the control device calculates corrections, and the alignment unit automatically adjusts mirrors to maintain precise alignment without manual intervention, enabling rapid realignment while preserving alignment precision
Solution Approach 2:
The system implements continuous feedback control where the detection unit measures calibration beam positions, compares them against reference positions, and feeds correction signals back to the alignment unit to automatically compensate for misalignments caused by environmental variations, resolving the contradiction between precision and realignment time
2Reliability
If manual realignment is performed frequently, then system performance is maintained, but productivity is reduced
Solution Approach 1:
The automated self-alignment system continuously maintains system performance by detecting and correcting alignment drift without requiring manual intervention, thereby preserving reliability while eliminating the productivity loss associated with frequent manual realignment operations
Solution Approach 2:
The system maintains continuous alignment monitoring and correction, ensuring uninterrupted useful action of the quantum system without the interruptions caused by manual realignment cycles, thus improving both reliability and productivity simultaneously
3Speed
If automated alignment is implemented, then realignment speed is improved, but device complexity increases
Solution Approach 1:
The alignment system is segmented into distinct functional modules: a detection unit for measuring beam position, a control device for calculating corrections, and an alignment unit with movable mirrors for execution. This modular segmentation enables automated realignment while managing complexity through functional decomposition and independent optimization of each subsystem
