Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If wireless tracking devices are used continuously to monitor asset location, then tracking visibility is improved, but FAA regulation compliance deteriorates due to interference with aircraft navigation and communication systems
Solution Approach 1:
The tracking device dynamically adjusts its operational state based on aircraft phase. The system transitions between active tracking mode (when aircraft is stationary or in flight) and inactive mode (during critical phases like takeoff and landing), allowing continuous adaptation to regulatory requirements while maintaining tracking visibility when safe to do so.
Solution Approach 2:
The device automatically detects aircraft movement and phase through integrated sensors (accelerometers, barometers, GPS) and self-regulates its transmission state without external intervention. This self-service capability ensures compliance with FAA regulations while maintaining continuous tracking functionality, resolving the contradiction between visibility and compliance.
2Duration of action of moving object
If lithium-based batteries are used to power tracking devices, then operational duration is improved, but safety and operational ease deteriorate due to explosive risks and bulkiness
Solution Approach 1:
The system replaces long-lasting but hazardous lithium batteries with smaller, safer, disposable battery compartments that can be easily replaced. This approach sacrifices some operational duration but dramatically improves safety by eliminating explosive risks and reduces bulkiness, allowing compact device design suitable for container attachment.
Solution Approach 2:
The device incorporates a removable battery compartment design that allows quick discarding of depleted batteries and replacement with fresh ones. This enables maintenance of operational duration through frequent replacement while using smaller, safer battery units, resolving the contradiction between duration and safety/bulkiness.
3Measurement precision
If sensor arrays with high frame rates are used to detect aircraft movement, then detection precision is improved, but energy consumption increases
Solution Approach 1:
The sensor array operates in periodic intervals rather than continuously. The system uses low-frame-rate monitoring during stable phases and switches to high-frame-rate detection only when movement is detected or during critical transitions (takeoff, landing). This periodic operation maintains high detection precision when needed while dramatically reducing average energy consumption.
Solution Approach 2:
The frame rate dynamically adjusts based on detected motion intensity and aircraft phase. During critical phases like takeoff and landing, the system increases frame rate for precise detection. During stable cruise phases, it reduces frame rate to conserve energy. This dynamic adjustment resolves the contradiction between precision and energy consumption.
