Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If real sensor data and simulated sensor data are mixed in the training system, then the training realism and effectiveness are improved, but the system complexity and difficulty of implementation increase
Solution Approach 1:
The system separates real sensor data processing and simulated sensor data processing into distinct processing paths. Real data from sensors (16A-16D) is processed through dedicated pilot modules (20A-20D), while simulated data from the simulation module (37) follows a separate path. This segmentation allows independent management of data sources, reducing the complexity of integrating them while maintaining training realism.
Solution Approach 2:
The tactical scenario server (18) acts as an intermediary that coordinates between the simulation module (37) and the display system. It manages the injection of simulated measurement signals into the training scenario without directly interfering with real sensor data processing. This intermediary structure simplifies the overall system architecture by providing a centralized control point for data mixing.
2Adaptability or versatility
If simulated measurement signals are injected into the training scenario, then the training scenarios become more diverse and realistic, but the consistency and reliability of the training system may be compromised
Solution Approach 1:
The system implements feedback mechanisms where the tactical scenario server (18) monitors the training scenario state and adjusts the injection of simulated signals accordingly. The pilot modules (20A-20D) receive both real and simulated data, process them through consistent logic, and provide feedback to ensure the training scenario remains reliable and consistent with the underlying physics and operational parameters.
Solution Approach 2:
The simulation module (37) generates simulated measurement signals with parameters that match the characteristics of real sensor data. By carefully controlling parameters such as signal strength, frequency, and temporal characteristics, the system maintains consistency between real and simulated data streams, ensuring reliability while achieving scenario diversity.
3Device complexity
If the system processes both real and simulated sensor data through the same pilot modules, then the implementation is simplified, but the operational safety may be impacted
Solution Approach 1:
The system segments data processing by creating distinct pathways: real sensor data from sensors (16A-16D) is processed through pilot modules (20A-20D) with clear identification of its origin. Simulated data from the simulation module (37) is processed separately and then integrated at the tactical situation module (22). This segmentation maintains operational safety by preventing confusion between real and simulated data while keeping the implementation manageable.
