Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single forward error correction mode is used for data transmission, then error correction capability is provided, but flexibility and adaptability to varying data link conditions deteriorate
Solution Approach 1:
The patent implements dynamic mode switching between different forward error correction modes (first FEC mode and second FEC mode) based on real-time data link conditions. The transmitting end device monitors link status and dynamically selects the appropriate FEC mode, transforming the static single-mode system into a dynamic multi-mode system that adapts to varying transmission conditions.
Solution Approach 2:
The patent changes the operational parameters of the error correction system by introducing multiple FEC modes with different correction capabilities. The system selects between first FEC mode (with stronger correction capability) and second FEC mode (with weaker correction capability) based on data link conditions, thereby adjusting the error correction parameters dynamically to match transmission quality.
2Device complexity
If a single error correction mode is used, then device complexity is reduced, but adaptability to different data link conditions deteriorates
Solution Approach 1:
The patent makes the error correction system universal by enabling it to perform multiple functions through different FEC modes. The transmitting end and receiving end devices both support first FEC mode and second FEC mode, allowing the system to adapt to various data link conditions while maintaining a unified multi-functional architecture.
Solution Approach 2:
The system introduces dynamic mode selection capability where the transmitting end determines the current data link condition and selects the appropriate FEC mode accordingly. This dynamic adjustment allows the system to maintain relatively simple operation while achieving high adaptability through real-time mode switching based on link quality.
3Ease of operation
If error correction mode is not matched to data link conditions, then operation is simpler, but error correction performance deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the transmitting end continuously monitors data link conditions and uses this feedback information to select the appropriate FEC mode. The system receives feedback about link quality and automatically adjusts the error correction mode accordingly, ensuring optimal error correction performance without requiring manual intervention.
Solution Approach 2:
The error correction system performs self-service by automatically determining the current data link condition and selecting the appropriate FEC mode without external control. The transmitting end device autonomously monitors link status and switches between first FEC mode and second FEC mode based on its own assessment of transmission conditions, eliminating the need for complex external mode management.
