Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the apparatus uses full Uu transmission systems for communication, then communication reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces a personal mobile terminal as an intermediary relay station between the lightweight vehicle apparatus and the network. The mobile terminal performs the complex Uu interface communication functions, while the vehicle apparatus only needs basic sidelink capabilities. This mediator approach allows reliable network communication without requiring full-capability radio systems in the vehicle.
Solution Approach 2:
The communication function is segmented into two parts: the mobile terminal handles the Uu interface communication with the network, while the vehicle apparatus handles only the sidelink V2X communication. This functional segmentation allows the vehicle to use reduced radio capabilities while maintaining communication reliability through the mobile terminal's full capabilities.
2Device complexity
If the apparatus remains inactive on Uu interface, then device complexity is reduced, but sidelink configuration may be disrupted
Solution Approach 1:
The mobile terminal serves as a stable intermediary that maintains continuous Uu interface connection to the network. Even when the vehicle apparatus is inactive on Uu, the mobile terminal keeps the network connection active, ensuring that sidelink configuration parameters are continuously maintained and updated without disruption.
Solution Approach 2:
The mobile terminal performs preliminary configuration actions by establishing and maintaining the Uu interface connection in advance. This preliminary action ensures that when the vehicle apparatus needs to communicate, the configuration is already in place and active, preventing any disruption to sidelink operations.
3Ease of manufacture
If the apparatus uses reduced radio capabilities, then device cost is reduced, but communication versatility decreases
Solution Approach 1:
The personal mobile terminal provides universal communication capabilities that work for various communication scenarios (V2V, V2I, V2N). By offloading the communication functions to the mobile terminal, the vehicle apparatus achieves versatile communication without needing multiple specialized radio systems, thus reducing manufacturing cost while maintaining versatility.
Solution Approach 2:
The mobile terminal acts as a versatile intermediary that adapts to different communication scenarios and network conditions. It provides the vehicle apparatus with access to various communication modes and network resources without requiring the vehicle to have built-in capabilities for all these modes, thereby reducing cost while maintaining versatility.
