Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If geosynchronous orbit satellite systems are used to provide high-speed data services, then coverage area is improved, but packet round-trip time increases
Solution Approach 1:
The patent segments the satellite communication system into multiple operational modes: geosynchronous orbit mode for high-speed data services with wide coverage, and low earth orbit mode for low-latency applications. This allows the system to select the appropriate orbit mode based on application requirements, resolving the contradiction between coverage area and packet round-trip time.
2Loss of time
If low earth orbit satellite systems are used to reduce packet round-trip time, then latency is improved, but antenna performance requirements increase
Solution Approach 1:
The patent implements a universal satellite communication system that can operate in both geosynchronous orbit and low earth orbit modes using the same terminal equipment. The system automatically selects the appropriate orbit mode based on availability and application needs, eliminating the need for separate specialized antennas for each mode and reducing overall antenna performance requirements.
3Area of stationary object
If GEO satellites are integrated with cellular technologies, then widespread residential coverage is improved, but device complexity increases
Solution Approach 1:
The patent merges GEO satellite communication and cellular network technologies into a unified communication system. The terminal equipment integrates both satellite and cellular communication capabilities, allowing automatic selection between the two networks based on availability and performance requirements. This consolidation reduces device complexity compared to having separate systems while maintaining widespread residential coverage.
4Area of stationary object
If conventional combining techniques are used for GEO and LEO satellite systems, then network coverage is improved, but data transmission performance deteriorates
Solution Approach 1:
The patent implements dynamic path selection that adapts to real-time network conditions. The system continuously monitors the performance of available satellite and cellular networks and dynamically switches between them based on current availability, signal quality, and application requirements. This dynamic approach maintains optimal data transmission performance while ensuring comprehensive network coverage.
