Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the satellite performs a complete digital processing operation on the received signal, then the processing completeness is improved, but the transmission delay increases
Solution Approach 1:
The patent divides the complete digital processing operation into multiple segments that can be distributed between the satellite and terrestrial station. The satellite performs initial processing (e.g., beamforming, filtering) on received signals, then transmits partially processed signals to the terrestrial station for further processing (e.g., advanced signal analysis, data extraction). This segmentation reduces the time the signal spends in transit while maintaining complete processing functionality across the distributed system.
2Loss of time
If the satellite segments the digital processing operation and sends only partially processed signals to the terrestrial station, then the transmission delay is reduced, but the system complexity increases
Solution Approach 1:
The patent designs the satellite and terrestrial station with multi-functional processing capabilities that can handle multiple types of signal operations. The satellite is equipped with basic digital signal processing functions (filtering, beamforming, modulation), while the terrestrial station provides advanced processing capabilities. This universal design allows the system to flexibly segment processing tasks based on real-time requirements without needing separate dedicated hardware for each function, thereby managing complexity while maintaining versatility.
Solution Approach 2:
The patent implements dynamic segmentation where the division of processing tasks between satellite and terrestrial station can be adjusted based on operational conditions. The system can dynamically reconfigure which processing steps occur at the satellite versus the terrestrial station, allowing optimization of delay versus complexity trade-offs in real-time based on signal characteristics, network conditions, and service requirements.
3Adaptability or versatility
If different cell types (IoT, high-speed, hotspot) require different processing strategies, then the adaptability is improved, but the control complexity increases
Solution Approach 1:
The patent applies local quality by tailoring the digital processing operation segmentation specifically to each cell type's requirements. For IoT cells with low data rates, minimal processing is performed at the satellite with basic filtering. For high-speed cells requiring low latency, more processing is distributed to reduce satellite burden. For hotspot cells with high traffic volumes, the satellite performs aggressive filtering and beamforming to reduce terrestrial station workload. This localized optimization for each cell type avoids a one-size-fits-all complex control system.
Solution Approach 2:
The patent changes processing parameters (such as filter order, beamforming complexity, sampling rates, and processing thresholds) based on cell type characteristics. The system dynamically adjusts these parameters to match the specific requirements of IoT, high-speed, or hotspot cells, enabling adaptability through parameter tuning rather than structural complexity increases.
