Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gain of the equalizer is increased to enhance signal magnitude, then signal reception performance improves, but noise component is amplified which degrades performance
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the equalizer gain based on received signal strength indicators (RSSI). The system continuously monitors signal conditions and modifies the gain parameter to optimize signal reception while preventing excessive noise amplification. This is achieved through feedback mechanisms that adapt the equalizer configuration in real-time based on actual signal quality measurements.
2Ease of operation
If manual configuration method is used for equalizer gain setting, then configuration process is simple, but accuracy in configuring the equalizer deteriorates and excessive effort is required
Solution Approach 1:
The patent implements self-service by enabling the equalizer configuration to be automatically optimized without manual intervention. The system performs self-diagnosis and self-adjustment by monitoring signal characteristics and autonomously determining optimal gain settings. This eliminates the need for manual configuration while achieving high accuracy through automated feedback loops and adaptive algorithms.
Solution Approach 2:
The patent applies feedback principles by continuously monitoring signal reception quality metrics and using this information to adjust equalizer parameters. The system receives feedback about signal strength and quality, processes this information, and automatically modifies the equalizer gain to maintain optimal performance. This closed-loop control ensures accurate configuration without requiring manual effort.
3Object-generated harmful factors
If the gain of the equalizer is decreased to reduce noise amplification, then noise component is reduced, but signal magnitude is reduced causing inter-symbol interference
Solution Approach 1:
The patent applies dynamics by transitioning from static equalizer gain settings to dynamic, adaptive gain control. The system continuously adjusts the equalizer parameters based on real-time signal conditions, allowing the gain to vary over time according to actual reception requirements. This dynamic adaptation enables the system to maintain optimal signal-to-noise ratio under varying channel conditions.
