Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If offline evaluation methods are used to assess tracking quality, then measurement precision can be improved, but loss of time increases and real-time feedback is not available
Solution Approach 1:
The system pre-computes and stores ideal trajectory references and performance criteria before actual tracking occurs. During real-time operation, the system compares current tracking data against these pre-prepared references, enabling immediate quality assessment without performing complex offline calculations during the evaluation moment.
Solution Approach 2:
The system implements real-time feedback mechanisms by continuously monitoring tracking performance parameters and comparing them against ideal trajectories. The control module receives tracking data, computes performance metrics immediately, and provides feedback signals that can trigger corrective actions, thus eliminating the time delay inherent in post-event offline evaluations.
2Measurement precision
If comprehensive sensor data is collected for accurate tracking, then measurement precision improves, but device complexity increases
Solution Approach 1:
The system divides the comprehensive sensor data into distinct functional components: position data from radar, heading data from navigation systems, and speed data from doppler measurements. Each data type is processed separately through dedicated algorithms, then integrated into a unified track representation. This segmentation allows the system to manage complexity by handling data streams independently while maintaining comprehensive tracking capability.
Solution Approach 2:
The control module is designed as a multi-functional unit that can process various sensor types and data formats through a unified architecture. The same control algorithm framework handles different sensor inputs (radar, GPS, inertial navigation) by adapting to their specific characteristics, thereby reducing overall system complexity compared to having separate specialized processors for each sensor type.
3Productivity
If real-time tracking quality assessment is implemented, then productivity improves, but device complexity increases due to additional control functions
Solution Approach 1:
The system merges the tracking function and quality assessment function into a single integrated control module. Rather than having separate independent systems for tracking and evaluation, the control module simultaneously performs trajectory estimation, performance calculation, and quality assessment using combined algorithms. This integration eliminates the need for additional standalone assessment systems while improving productivity through real-time feedback.
Solution Approach 2:
The tracking system performs self-assessment by internally comparing its own output against ideal trajectories and computing performance metrics without requiring external evaluation systems. The control module monitors its own tracking quality in real-time, generating self-diagnostic information that can trigger corrective actions. This self-service capability improves productivity while avoiding the complexity of external assessment infrastructure.
