Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional error correction mechanisms are continuously activated, then error correction performance is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic activation of error correction mechanisms based on real-time channel conditions. The system monitors channel quality metrics and selectively activates the complex Nyquist error correction module only when channel conditions deteriorate below a threshold, rather than continuously operating. This dynamic approach maintains reliable error correction when needed while minimizing power consumption during good channel conditions.
Solution Approach 2:
The system changes operational parameters by switching between different error correction modes based on channel conditions. When channel quality is good, the system uses a simplified mode with lower power consumption. When channel quality degrades, the system transitions to the full Nyquist error correction mode with enhanced parameters for maximum error correction capability, thus adapting power consumption and performance to actual needs.
2Use of energy by moving object
If simple error correction methods are used, then power consumption is reduced, but error correction performance deteriorates
Solution Approach 1:
The patent employs a dynamic error correction system that adapts its complexity based on channel conditions. Rather than using a fixed simple method, the system continuously monitors channel quality and transitions between simplified and complex correction modes. This ensures that when channel conditions deteriorate, the full-performance Nyquist error correction is activated to maintain reliability, while during good conditions, simpler methods suffice for lower power consumption.
Solution Approach 2:
The system applies partial error correction action by using simplified methods when channel conditions permit, and excessive (full) correction capability when conditions require it. This partial/excessive approach allows the system to use more power and complex processing than minimum required during good conditions, but activates full correction capability when needed to ensure reliability, rather than always operating at maximum capability.
3Reliability
If complex decoding is always activated, then error correction capability is improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamically configurable decoder that adjusts its complexity based on channel conditions. The system includes a channel quality determination module that triggers activation of the complex Nyquist error correction decoder only when channel conditions fall below a threshold. During normal operation, a simpler decoding path is used, reducing computational complexity and resource requirements while maintaining adequate performance.
Solution Approach 2:
The error correction system is segmented into multiple independent modules: a channel quality determination module, a simple error correction module for good conditions, and a complex Nyquist error correction module for poor conditions. This segmentation allows the system to selectively engage only the necessary complexity level, avoiding the need to always operate the most complex decoder and thus reducing average device complexity and resource usage.
