Engineering Contradiction Analysis
1Reliability
If multiple wireless communication interfaces are used for UTM communication, then reliability is improved, but device complexity increases
Solution Approach 1:
The gateway is segmented into multiple independent wireless communication interfaces (first wireless communication interface, second wireless communication interface) that can operate independently. Each interface maintains separate communication paths to different network devices, allowing the system to achieve high reliability through redundancy while managing complexity by dividing the communication function into discrete, modular components.
Solution Approach 2:
The system changes the parameter of interface redundancy by configuring multiple wireless communication interfaces with different operational characteristics. The first interface uses a first communication protocol while the second interface uses a second communication protocol, allowing the system to adapt to different network conditions and maintain communication reliability despite individual interface failures.
2Reliability
If redundant communication paths are implemented, then communication continuity is improved, but system complexity increases
Solution Approach 1:
The gateway acts as an intermediary device that manages multiple wireless communication interfaces and their corresponding communication paths. It mediates between the UAS and various network devices, intelligently selecting which interface to use based on operational status. This intermediary function simplifies the overall system by centralizing the complexity of managing redundant paths within the gateway itself.
Solution Approach 2:
The system implements dynamic path selection where the gateway can switch between different wireless communication interfaces based on real-time operational conditions. If the first wireless communication interface fails, the system dynamically transitions to use the second interface, maintaining communication continuity without requiring manual reconfiguration or complex static routing setups.
3Reliability
If multiple communication interfaces are used, then fault tolerance is improved, but ease of operation decreases
Solution Approach 1:
The gateway is configured to automatically monitor the operational status of its wireless communication interfaces and self-manage the selection of active interfaces without external intervention. The system performs self-diagnosis and self-reconfiguration, automatically switching to backup interfaces when failures are detected, thereby maintaining fault tolerance while simplifying operation for end users who do not need to manually manage the complexity of multiple interfaces.
