Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvecommunication reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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.

Inventive Principle:
Principle #15Dynamics

2Loss of energy

If data is transmitted without compression, then the transmission speed is maintained, but the bandwidth consumption increases

Engineering Contradiction:
Improvebandwidth consumptionVSAvoidtransmission speed
Core Design Contradiction:
Loss of energyVSSpeed

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.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple communication channels are supported with different standards, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Loss of energy

If data compression is applied, then the bandwidth consumption is reduced, but the processing time increases

Engineering Contradiction:
Improvebandwidth consumptionVSAvoidprocessing time
Core Design Contradiction:
Loss of energyVSLoss of time

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.

Inventive Principle:
Principle #35Parameter changes
