Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional alignment techniques are used for single-core fibers, then the alignment process is simple, but multi-core fibers cannot be properly aligned considering marker positioning requirements
Solution Approach 1:
The alignment process is divided into distinct phases: first aligning the markers of multi-core fibers, then aligning the cores based on the marker positions. This segmentation allows the complex multi-core fiber alignment to be broken down into manageable steps that can be handled by conventional alignment mechanisms.
Solution Approach 2:
The marker alignment is performed as a preliminary action before core alignment. By first positioning the markers correctly using the alignment mechanism, the subsequent core alignment can proceed with reference to the established marker positions, simplifying the overall process.
2Manufacturing precision
If marker alignment is performed before core alignment, then proper positioning is achieved, but the alignment process requires multiple steps
Solution Approach 1:
The alignment process maintains continuity by using the marker alignment results directly as the reference for core alignment without interrupting the process. The alignment mechanism continues operating, transitioning smoothly from marker positioning to core positioning based on the established marker configuration.
Solution Approach 2:
The system uses feedback from the marker alignment measurement to guide the subsequent core alignment. The measured marker positions provide reference information that feeds into the core alignment control, ensuring that core positioning is based on the actual achieved marker positions rather than theoretical values.
3Measurement precision
If automated alignment control is implemented for multi-core fibers, then alignment accuracy is improved, but the control system becomes more complex
Solution Approach 1:
The alignment control system is designed to perform multiple functions: it can identify marker positions, calculate optimal alignment configurations, and control the alignment mechanism for both marker and core alignment. This multi-functionality reduces the need for separate specialized systems while maintaining high measurement precision.
Solution Approach 2:
The system automatically identifies marker positions and determines the alignment configuration without requiring manual intervention. The control device self-regulates the alignment process by using the measured marker positions to automatically calculate and execute the appropriate core alignment, reducing operational complexity.
