Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional handover methods are used in mobile communication systems, then handover can be performed between base stations, but frequent changes in network topology due to vehicle mobility cause interruptions in communication paths and reduce network performance
Solution Approach 1:
The patent implements dynamic beamforming that continuously adapts to mobile node locations and network topology changes. The beamforming control signal is dynamically adjusted based on real-time mobile profile information, allowing the system to maintain stable communication paths even during high-speed mobility and frequent handovers, thereby resolving the contradiction between communication stability and network performance
Solution Approach 2:
The system employs feedback mechanisms where the mobile profile information processor continuously monitors mobile node locations and communicates this information to the beamforming controller. This feedback loop enables real-time adjustment of beamforming parameters to maintain optimal communication paths, preventing interruptions and improving overall network performance during mobility
2Reliability
If beamforming control is implemented based on mobile node locations, then communication stability during mobility is improved, but system complexity increases due to additional processing requirements
Solution Approach 1:
The mobile profile information processor serves multiple functions: it tracks mobile node locations, generates beamforming control signals, and manages handover indications. By consolidating these functions into a single multi-functional component, the system achieves improved connection stability during mobility while minimizing the increase in overall system complexity
