Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual setup of training scenarios is performed for each radar device type, then training accuracy can be achieved, but training time and cost increase significantly
Solution Approach 1:
The patent creates virtual copies of training scenarios through signal generators that simulate electromagnetic environments. Instead of manually setting up physical training scenarios for each radar device, the system generates synthetic test signals that replicate real-world electromagnetic conditions, allowing automated training while maintaining training quality.
Solution Approach 2:
The training system automatically adapts parameters of test signals based on feedback from the radar device's machine learning module. The controller modifies signal characteristics such as frequency, amplitude, and waveform to optimize training effectiveness, eliminating the need for manual parameter adjustment while maintaining high training accuracy.
2Reliability
If manual configuration of training scenarios is performed, then radar device training can be conducted, but operational complexity increases
Solution Approach 1:
The training system performs self-configuration through automated feedback loops. The controller receives feedback signals from the radar device, analyzes performance metrics, and automatically adjusts training parameters without requiring manual intervention. This self-service mechanism maintains training effectiveness while dramatically reducing operational complexity.
Solution Approach 2:
The system implements continuous feedback monitoring where the radar device's machine learning module processes test signals and generates feedback signals that are analyzed by the controller. This feedback drives automatic parameter adaptation, ensuring training effectiveness while eliminating manual configuration requirements.
3Adaptability or versatility
If multiple training scenarios are set up manually for different radar devices, then comprehensive training coverage is achieved, but resource consumption increases
Solution Approach 1:
The training system uses universal signal generators that can simulate multiple electromagnetic environments and scenarios. A single training system can adapt to train different types of radar devices by programmatically generating diverse test signals, eliminating the need for separate physical training setups for each device type and reducing overall resource consumption.
