Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single data connection is used for communication in an electric aircraft, then the device complexity is reduced, but the reliability of communication deteriorates due to susceptibility to failures and inefficiency
Solution Approach 1:
The communication system is segmented into multiple independent data connections (primary, secondary, and tertiary connections) rather than relying on a single connection. This segmentation allows the system to divide communication pathways into separate channels, where each connection can operate independently. When one connection fails, others remain functional, thereby improving communication reliability without requiring a complete system redesign.
Solution Approach 2:
The system implements beforehand cushioning by establishing backup data connections (secondary and tertiary) in advance before any communication failure occurs. These redundant connections are prepared and monitored proactively, so when the primary connection fails, the system can immediately switch to a backup connection without interruption or delay, cushioning against the impact of communication failures.
2Reliability
If multiple data connections are implemented for redundant communication, then the reliability of communication is improved, but the device complexity increases due to additional connections and selection mechanisms
Solution Approach 1:
The communication system employs dynamics by implementing automatic, real-time switching between data connections based on their operational status. The system dynamically monitors the health and performance of each connection and automatically selects the most appropriate active connection without requiring manual intervention. This dynamic adaptation allows the system to maintain optimal communication reliability while managing complexity through automated rather than manual control mechanisms.
Solution Approach 2:
The communication system implements self-service by autonomously monitoring its own connections and performing self-diagnosis to determine connection status. The system automatically selects and switches between active and standby connections based on real-time conditions without external control, enabling it to manage its own complexity and maintain reliability through self-directed operation.
3Ease of operation
If automatic connection switching is implemented based on state data, then the ease of operation is improved, but the device complexity increases due to the need for monitoring and selection logic
Solution Approach 1:
The connection switching mechanism operates through self-service by automatically monitoring the status of multiple data connections and autonomously selecting the appropriate active connection based on predefined criteria. The system performs self-diagnosis and self-management of connection switching without requiring pilot intervention or external control, thereby improving ease of operation while containing complexity within the automated switching logic itself.
