Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional sensor systems and processing capabilities are used, then the system structure remains simple, but the object detection and classification accuracy cannot reach human-like levels in dynamic and complex environments
Solution Approach 1:
The system segments object detection into multiple polarization channels (horizontal and vertical), with dedicated iMTS antennas and neural network processors for each channel. This segmentation allows independent optimization of each detection pathway, achieving human-like classification accuracy while managing system complexity through modular architecture.
Solution Approach 2:
The patent employs intelligent metamaterial (iMTS) antennas that combine traditional antenna structures with programmable metamaterial elements. These composite antenna structures enable dynamic polarization control and enhanced signal processing capabilities, directly improving object detection accuracy in complex environments.
2Measurement precision
If iMTS antennas with targeted polarization are implemented, then object identification accuracy improves to over 90%, but the antenna structure and system complexity increase
Solution Approach 1:
The iMTS antenna structure incorporates dynamically reconfigurable elements that can adjust polarization states in real-time based on target characteristics. This dynamic capability allows the antenna to optimize its polarization orientation for different objects (vehicles, pedestrians, cyclists), achieving over 90% identification accuracy while adapting to varying environmental conditions.
Solution Approach 2:
The system changes the polarization parameter of transmitted and received signals to match the orientation of detected objects. By adjusting polarization angles and states according to object type and orientation, the system achieves high identification accuracy. The neural network processes these polarization-specific signals to classify objects with greater than 90% accuracy.
3Loss of information
If multiple sensors and AI processing systems are integrated, then the system can achieve human-like environmental understanding, but the processing time and computational requirements increase
Solution Approach 1:
The system performs preliminary signal processing and feature extraction at the antenna level before transmitting data to the neural network. The iMTS antennas pre-process radar signals by separating polarization components and extracting initial object features, reducing the computational burden on the AI processor and enabling faster real-time environmental understanding.
Solution Approach 2:
The patent replaces traditional mechanical object classification methods with neural network-based AI processing. The neural network automatically learns and extracts object features from polarization-specific radar signals, achieving human-like environmental understanding without explicit programming. This substitution enables rapid processing of complex environmental data in real-time.
