Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wired optical communication is used for high-speed data transmission, then data transmission speed and capacity are improved, but connection reliability deteriorates due to sensitivity to connection failures from dirt, dust, and mechanical stress
Solution Approach 1:
The system dynamically switches transmission paths based on real-time quality assessments. The switch component enables the system to adapt its connection configuration in response to changing transmission conditions, allowing high-speed optical communication to maintain reliability by rerouting around degraded connections without reducing transmission speed on functional paths.
Solution Approach 2:
The system changes the operational parameters by selecting different transmission paths based on quality metrics. By monitoring transmission quality and adjusting the active path configuration, the system maintains optimal data transmission speed while compensating for connection reliability issues through parameter-based path selection rather than reducing overall transmission performance.
2Reliability
If multiple transmission paths are provided with switching capability, then connection reliability is improved through path diversification, but device complexity increases due to additional switching components and control mechanisms
Solution Approach 1:
The system segments the transmission function into multiple independent paths with a switching component that selectively activates them. This segmentation allows the complexity to be distributed across simpler modular path units rather than requiring a single complex high-reliability channel, making the overall system more manageable while achieving redundancy.
Solution Approach 2:
The switch acts as an intermediary component that manages the complexity of path selection. Rather than requiring complex error correction or redundant verification in each transmission path, the intermediary switch handles reliability by routing around failures, simplifying the overall system architecture while maintaining connection reliability through centralized path management.
3Reliability
If data is prioritized based on weight and transmitted through quality-assured paths, then data transmission reliability is improved, but transmission processing complexity increases due to path association and quality monitoring requirements
Solution Approach 1:
The system performs preliminary assessment of transmission path quality before data transmission begins. By pre-evaluating and ranking available paths based on quality metrics, the system establishes an optimized routing configuration in advance, reducing the complexity of real-time decision-making during actual data transmission while ensuring high-reliability paths are selected for priority data.
Solution Approach 2:
The transmission quality assessment mechanism provides feedback on path performance that informs subsequent routing decisions. This feedback loop allows the system to automatically adjust path selection based on observed transmission quality, improving reliability through adaptive path association while managing processing complexity through automated quality-based decision algorithms rather than manual configuration.
