Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If satellite terminals are upgraded to support preset communication standards (4G/5G), then communication compatibility with terrestrial networks is improved, but device complexity and upgrade costs increase
Solution Approach 1:
The patent introduces a satellite device as an intermediary between satellite terminals and terrestrial networks. The satellite device performs protocol conversion and message translation, allowing terminals without preset communication standard support to communicate through the satellite device which handles the standard-compliant communication with the terrestrial network.
Solution Approach 2:
The communication system is segmented into distinct functional components: satellite terminals, satellite device, and terrestrial network. The satellite device separates the communication functions by handling protocol conversion independently, allowing terminals to remain simple while achieving network compatibility through the segmented architecture.
2Device complexity
If satellite terminals directly access terrestrial networks without upgrades, then device complexity is reduced, but communication reliability deteriorates due to protocol incompatibility
Solution Approach 1:
The satellite device acts as a mediator that ensures reliable communication by translating messages between terminals and the terrestrial network. It performs protocol adaptation and address translation, guaranteeing communication reliability while allowing terminals to remain simple without direct network access capabilities.
Solution Approach 2:
The satellite device provides self-service protocol conversion and message translation capabilities, automatically adapting communications without requiring terminal upgrades. The system maintains reliability through the satellite device's inherent ability to handle protocol incompatibilities.
3Adaptability or versatility
If protocol conversion is implemented through terminal upgrades, then communication compatibility is improved, but ease of operation worsens due to complex upgrade processes
Solution Approach 1:
The satellite device serves as an intermediary that handles all protocol conversion operations centrally. This eliminates the need for complex terminal upgrades, as the satellite device automatically performs message translation and protocol adaptation, simplifying the operational process for users.
Solution Approach 2:
The satellite device provides universal protocol conversion capabilities that work with multiple terminal types and network standards. This multi-functional approach allows a single satellite device to serve various terminals without requiring terminal-specific upgrades, improving ease of operation.
4Measurement precision
If direct communication channels are established for each terminal type, then communication precision is improved, but device complexity increases
Solution Approach 1:
The satellite device acts as a central intermediary that manages all communication channels. It performs address translation and message routing, ensuring precise communication delivery while centralizing channel management to avoid the complexity of establishing separate direct channels for each terminal type.
Solution Approach 2:
Multiple communication channels are merged into a single standardized interface through the satellite device. The device combines various terminal communication protocols into unified message formats, maintaining communication precision while reducing channel management complexity through consolidation.
