Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single communication channel is used for data transmission, then the device complexity is reduced, but the communication reliability deteriorates when the channel becomes unavailable or overloaded
Solution Approach 1:
The communication device is designed to support multiple communication channels (GEO SatCom, MEO SatCom, LEO SatCom, 4G/5G, LAN, WIFI) simultaneously, making it universally capable of operating across different communication infrastructures. This multi-functionality ensures that if one channel fails or becomes overloaded, the device can switch to alternative channels, thereby maintaining communication reliability without requiring separate dedicated devices for each channel type.
Solution Approach 2:
The system dynamically selects and switches between different communication channels based on real-time channel conditions, available transmission bandwidth, and current communication needs. The channel selection unit continuously monitors channel availability and performance, adapting the communication path dynamically rather than relying on a static single-channel configuration. This dynamic approach maintains reliability while managing device complexity through intelligent resource allocation.
2Loss of energy
If data is transmitted without compression, then the transmission speed is maintained, but the bandwidth consumption increases
Solution Approach 1:
The compression unit changes the parameter of data representation by applying compression algorithms to reduce the size of transmitted data. The system adjusts compression levels and techniques based on the selected communication channel's characteristics and available bandwidth, transforming data from an uncompressed state to a compressed state that consumes less bandwidth while maintaining acceptable transmission speeds through optimized compression ratios.
3Adaptability or versatility
If multiple communication channels are supported with different standards, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The communication device integrates support for multiple communication standards (GEO SatCom, MEO SatCom, LEO SatCom, 4G/5G, LAN, WIFI) within a single universal platform. This universality allows the device to adapt to different communication environments and standards without requiring separate dedicated hardware for each standard, thereby improving adaptability while managing complexity through shared underlying infrastructure and unified channel management.
4Loss of energy
If data compression is applied, then the bandwidth consumption is reduced, but the processing time increases
Solution Approach 1:
The compression unit applies parameter changes by adjusting compression ratios and algorithm selection based on the specific communication channel and data characteristics. For channels with higher bandwidth availability, lower compression ratios are used to minimize processing time, while for bandwidth-constrained channels, higher compression ratios are applied despite increased processing requirements. This dynamic parameter adjustment optimizes the trade-off between bandwidth consumption and processing time.
