Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional aircraft communication systems are used without comprehensive testing, then the system complexity remains low, but the ability to promptly diagnose and resolve network connectivity issues deteriorates
Solution Approach 1:
The system performs preliminary testing of communications components and links before connectivity issues occur. The method proactively tests each component (satellite antenna, satellite modem, L-band antenna, L-band modem, router, switches) and communication link to determine operational capability, so that problems are detected early rather than waiting for passenger complaints or connectivity failures.
Solution Approach 2:
The system implements continuous feedback by monitoring and reporting the operational capability of each communications component and link. The computing device receives test results from each component, processes this information, and provides real-time feedback about network connectivity status to flight crew and ground personnel, enabling informed decision-making about connectivity issues.
2Measurement precision
If comprehensive testing of all communications components and links is performed, then the precision of diagnosing connectivity problems is improved, but the time required for testing and system operation increases
Solution Approach 1:
The testing system divides the communication network into discrete, independently testable segments or components. Each communications component (satellite antenna, satellite modem, L-band antenna, L-band modem, router, switches) and communication link is tested separately and individually. This segmentation allows precise identification of which specific component or link is malfunctioning, rather than knowing only that the overall system is failing.
Solution Approach 2:
The system changes the parameter being measured from a general connectivity check to specific operational capability assessments of individual components and links. By testing each component's operational capability independently and aggregating these results, the system achieves comprehensive diagnostic precision without requiring complete system shutdown or manual inspection of each element.
3Loss of information
If detailed operational capability data for each communications component is collected and presented, then the information completeness for troubleshooting is improved, but the data processing and presentation complexity increases
Solution Approach 1:
The computing device performs multiple functions within a single integrated system: it collects test data from all communications components, processes the operational capability results, stores the information, and presents it in a comprehensible format. This multi-functionality eliminates the need for separate diagnostic tools and data presentation systems, reducing overall system complexity while maintaining complete information availability.
Solution Approach 2:
The computing device acts as an intermediary between the communications components and the users (flight crew, ground personnel). It receives raw test results from each component, processes this data to determine operational capability, and presents the processed information in a user-friendly format. This intermediary role simplifies the interface between complex diagnostic data and human users.
