Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal detectors, electromagnetic field detection devices, x-rays, or microwave technology are used to detect concealed objects, then detection capability is improved, but health risks increase due to radiation and radio wave exposure
Solution Approach 1:
The patent replaces electromagnetic detection systems (x-ray, microwave, metal detectors) with a thermal imaging-based deep learning system. Thermal cameras detect infrared radiation naturally emitted by objects without requiring harmful electromagnetic waves to be transmitted into the target area, thereby eliminating radiation exposure risks while maintaining detection capability through AI-powered image analysis
Solution Approach 2:
The patent introduces thermal imaging as an intermediary detection method that captures heat signatures without direct electromagnetic interaction with the target. The deep learning model then acts as a mediator to analyze thermal patterns and identify concealed objects, separating the detection function from harmful radiation sources
2Reliability
If conventional detection devices are used, then object detection is achieved, but continuous human supervision is required which reduces productivity
Solution Approach 1:
The patent implements a self-service detection system where the deep learning model automatically analyzes thermal images, identifies concealed objects, and generates alerts without requiring human operators to continuously monitor screens. The system serves itself by performing detection, classification, and notification functions autonomously, freeing human personnel from routine surveillance tasks
Solution Approach 2:
The patent replaces human visual inspection with automated deep learning-based image analysis. The neural network processes thermal images and makes detection decisions algorithmically, substituting human cognitive effort with computational processing that operates continuously without fatigue or distraction, thereby improving both accuracy and operational efficiency
3Device complexity
If thermal camera images are processed using traditional methods, then processing is simpler, but detection speed and accuracy are insufficient for real-time security applications
Solution Approach 1:
The patent transforms the detection approach by changing the processing parameters from traditional image analysis to deep learning-based feature extraction. The system adjusts parameters such as convolutional layer depths, activation functions, and training data configurations to optimize detection speed and accuracy for thermal imaging, achieving real-time performance through parameter optimization rather than architectural simplification
4Extent of automation
If deep learning models are used for detection, then automation and accuracy are improved, but computational complexity and processing requirements increase
Solution Approach 1:
The patent segments the deep learning processing into distinct functional modules: thermal image acquisition, pre-processing, feature extraction through convolutional layers, object classification, and alert generation. This segmentation allows each module to be optimized independently and enables parallel processing where possible, reducing overall computational complexity while maintaining high automation levels
