Engineering Contradiction Analysis
1Adaptability or versatility
If conventional radio receivers and transmitters use fixed circuits with adjustable components, then the device structure is simple and easy to manufacture, but the adaptability to different communication protocols and electromagnetic spectrum ranges is limited
Solution Approach 1:
The patent implements dynamic reconfigurability by allowing the radio circuit to change its characteristics in real-time based on detected electromagnetic waveforms. The system dynamically adjusts modulation types, frequency ranges, and communication protocols through software control rather than fixed hardware configurations, enabling adaptation to different protocols while maintaining a unified circuit structure.
Solution Approach 2:
The system changes operational parameters such as frequency, bandwidth, and modulation type based on the detected electromagnetic waveform characteristics. By using software-defined radio (SDR) technology, the patent allows parameters to be adjusted dynamically without physical circuit changes, resolving the contradiction between adaptability and circuit complexity.
2Adaptability or versatility
If conventional radios are configured to work with a single communication protocol, then the device complexity is reduced, but the ability to monitor diverse electromagnetic waveforms is limited
Solution Approach 1:
The patent creates a universal radio system that can perform multiple functions by detecting different electromagnetic waveform types and automatically adapting its operation. A single radio device can monitor communication signals, radar signals, and other electromagnetic waveforms by using machine learning to classify and respond to different signal types, eliminating the need for multiple specialized radios.
Solution Approach 2:
The system employs machine learning models that enable the radio to automatically identify and adapt to different electromagnetic waveform types without external configuration. The radio self-configures its parameters based on the detected signal characteristics, reducing the need for complex manual system configuration while expanding monitoring capabilities.
3Ease of operation
If fixed circuit radios are used, then the manufacturing cost is low and ease of manufacture is high, but the response capability to detected waveforms is insufficient
Solution Approach 1:
The patent replaces fixed mechanical/hardware circuit configurations with software-based control and machine learning algorithms. This substitution allows the system to have enhanced response capabilities through software intelligence while maintaining relatively simple hardware architecture, bridging the gap between manufacturing simplicity and operational sophistication.

AI summary
A method includes determining, based at least in part on parameters of a software defined radio (SDR), waveform data descriptive of an electromagnetic waveform. The method also includes obtaining sensor data distinct from the waveform data. The method further includes generating feature data based on the sensor data and the waveform data and providing the feature data as input to a first machine learning model and initiating a response action based on an output of the first machine learning model.
