Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual switching between different optical communication standards is used, then device complexity is reduced, but productivity and efficiency deteriorate due to manual intervention requirements
Solution Approach 1:
The system performs automatic signal switching without manual intervention. The detection module detects the optical signal type, and the control unit automatically controls the multiplexer to switch between GPON and XGPON modes, making the system self-sufficient and eliminating the need for operator involvement in the switching process
Solution Approach 2:
The detection module provides feedback about the detected optical signal type to the control unit, which then adjusts the multiplexer configuration accordingly. This closed-loop feedback mechanism enables automatic adaptation to different optical communication standards based on real-time signal detection
2Adaptability or versatility
If separate receiving circuits for GPON and XGPON are implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The receiving circuit is designed to handle multiple optical communication standards (GPON and XGPON) through a single unified structure. The multiplexer can be configured to receive signals from either standard, and the detection module identifies the signal type to route it to the appropriate processing path, eliminating the need for completely separate circuits for each standard
Solution Approach 2:
The receiving circuit employs dynamic switching capability through the multiplexer, which can be reconfigured based on the detected signal type. Instead of having fixed separate circuits, the system dynamically adjusts its configuration to accommodate different optical communication standards, providing versatility while maintaining a relatively simple base structure
3Measurement precision
If wavelength-based signal separation is used, then measurement precision is improved, but manufacturing precision requirements increase
Solution Approach 1:
The detection module serves as an intermediary that performs wavelength detection and uses this information to control the multiplexer. Rather than requiring the entire system to be manufactured with extremely high precision for wavelength separation, the detection module measures the wavelength and translates this information into control signals, decoupling the manufacturing precision requirements from the overall system performance
