Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a communication unit provides wireless connectivity with both terrestrial and non-terrestrial networks, then network coverage and connectivity reliability are improved, but device complexity increases
Solution Approach 1:
The patent combines terrestrial network connectivity and non-terrestrial network connectivity into a single integrated communication unit. The communication unit includes both a terrestrial network interface and a non-terrestrial network interface, allowing the vehicle to connect to either network type through one unified device rather than requiring separate communication systems. This merging approach improves connectivity reliability while managing device complexity through integration.
Solution Approach 2:
The communication unit is designed with multi-functionality to handle both terrestrial and non-terrestrial network connections. The single communication unit can selectively connect to either the terrestrial network or the non-terrestrial network based on availability and requirements, providing universal connectivity capability across different network types without requiring multiple specialized devices.
2Adaptability or versatility
If the communication unit enables seamless handover between terrestrial and non-terrestrial networks, then network adaptability is improved, but control complexity increases
Solution Approach 1:
The communication unit continuously monitors the availability and quality of both terrestrial and non-terrestrial network connections. Based on this feedback, the system automatically determines the optimal network to connect to and executes seamless handovers when switching between networks. This feedback mechanism enables adaptive network selection and handover control without requiring complex manual intervention.
Solution Approach 2:
The communication unit dynamically adjusts its network connection based on real-time conditions. The system can switch between terrestrial and non-terrestrial networks depending on signal availability, connection quality, and operational requirements. This dynamic adaptability allows the communication unit to respond flexibly to changing network conditions while maintaining optimal connectivity.
3Adaptability or versatility
If the communication unit provides wireless connectivity to multiple in-vehicle devices, then system versatility is improved, but device complexity increases
Solution Approach 1:
The communication unit is designed as a universal connectivity platform that can simultaneously provide wireless connections to multiple in-vehicle devices such as telecommunication control units, user equipment, and other vehicle systems. The single communication unit handles diverse connectivity requirements for different devices through integrated protocols and interfaces, eliminating the need for multiple separate communication systems throughout the vehicle.
