Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional security inspection methods are used, then the inspection process is simple, but the detection ability for dangerous items is limited and efficiency is low
Solution Approach 1:
The patent combines multiple detection technologies (metal detection, millimeter-wave imaging, terahertz detection, infrared thermal imaging) into a single integrated security inspection system. This merging of different detection methods enables comprehensive detection of various dangerous items including metallic objects, non-metallic substances, concealed weapons, and chemical reagents, thereby improving detection ability without significantly increasing inspection time
Solution Approach 2:
The security inspection system is designed with multi-functional detection capabilities that can identify different types of threats using various physical principles. The system can detect metallic objects through metal detection, non-metallic dangerous items through millimeter-wave and terahertz imaging, thermal anomalies through infrared detection, and can also perform multi-dimensional information analysis for behavior recognition, making it universally applicable to diverse security inspection scenarios
2Productivity
If manual inspection methods such as hand-touching and visual inspection are used, then the equipment is simple, but the inspection efficiency is low and inspected persons feel disgusted
Solution Approach 1:
The patent replaces manual mechanical inspection methods (hand-touching, visual inspection) with automated detection systems based on electromagnetic radiation and optical principles. The millimeter-wave, terahertz, and infrared detection devices automatically scan and analyze the inspected person and their belongings, eliminating the need for physical contact and manual examination, thereby improving inspection efficiency while enhancing the comfort and dignity of inspected persons
Solution Approach 2:
The system introduces electromagnetic fields (millimeter-wave, terahertz, infrared) as intermediaries to perform non-contact detection. These electromagnetic waves act as mediators that interact with the inspected person and objects without requiring physical contact, enabling automated inspection while maintaining the comfort and privacy of the inspected persons
3Measurement precision
If conventional security inspection gates are used, then the structure is simple, but they can only detect metal items and cannot detect non-metallic dangerous items
Solution Approach 1:
The patent integrates multiple detection technologies (metal detection, millimeter-wave imaging, terahertz detection, infrared thermal imaging) into a unified security inspection system. This combination enables the system to detect various types of dangerous items including metallic objects, non-metallic substances, concealed weapons, and chemical reagents, thereby significantly improving detection accuracy
Solution Approach 2:
The system transitions from single-dimensional metal detection to multi-dimensional detection by incorporating millimeter-wave imaging for non-metallic object detection, terahertz detection for chemical substance identification, and infrared thermal imaging for temperature-based anomaly detection. This multi-dimensional approach enables comprehensive detection across different material types and threat categories
