Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication device uses fixed frequency processing methods, then the device complexity is reduced, but the signal processing reliability deteriorates due to inability to adapt to different signal conditions
Solution Approach 1:
The patent implements dynamic frequency tuning by allowing the communication device to adjust shift frequency and baseband frequency based on detected signal conditions. The processor determines optimal frequency parameters in real-time, enabling the system to adapt to varying signal environments rather than using fixed frequency processing methods.
Solution Approach 2:
The patent changes the frequency parameters (shift frequency and baseband frequency) dynamically based on signal conditions. By detecting component radio frequency signals and their frequencies, the system adjusts these parameters to optimize signal processing reliability for different communication scenarios.
2Productivity
If the communication device processes all frequency components, then the signal processing completeness is improved, but the power consumption increases
Solution Approach 1:
The patent extracts and processes only the relevant frequency components by determining component radio frequency signals and their frequencies from the received signal. Instead of processing all frequency components uniformly, the system identifies and focuses computational resources on the specific frequency ranges that contain useful signal information.
Solution Approach 2:
The patent applies partial action by processing only the necessary frequency components rather than all frequency components. The system determines which frequency ranges contain signal content and processes those selectively, avoiding unnecessary computation on empty or irrelevant frequency bands.
3Adaptability or versatility
If the communication device uses broad frequency processing, then the adaptability to different signals is improved, but the signal processing precision deteriorates
Solution Approach 1:
The patent applies local quality by determining the specific frequency characteristics of component signals and tailoring the processing parameters to each detected signal's frequency range. The system adjusts shift frequency and baseband frequency based on the local frequency conditions of individual component signals, providing precise processing adapted to each signal's characteristics.
Solution Approach 2:
The patent changes processing parameters dynamically based on detected signal frequencies. By measuring the frequencies of component radio frequency signals and adjusting shift frequency and baseband frequency accordingly, the system maintains high processing precision while adapting to different signal types and frequency ranges.
