Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a metal detector door is used for security check, then metal items can be effectively identified, but non-metal items such as ceramic cutters, powders, liquids, and paper materials cannot be detected
Solution Approach 1:
The patent integrates multiple detection technologies (metal detection, magneto-optical imaging, radioactivity detection) into a single security check system that can simultaneously detect various types of prohibited items including metals, non-metals, and radioactive substances, making the system versatile and multi-functional
Solution Approach 2:
The system combines multiple detection modalities (metal detector, magneto-optical imaging system, radioactivity detector) into a composite detection system that leverages the strengths of each individual technology to achieve comprehensive detection capabilities
2Reliability
If manual inspection is used for security check, then professional verification can be performed, but it requires high professionalism, sense of responsibility, and it's difficult to determine accountability for errors
Solution Approach 1:
The security check system performs automatic detection and analysis without requiring manual intervention. The magneto-optical imaging system automatically captures images, the control system automatically analyzes the images for prohibited items, and the system automatically makes pass/fail decisions, eliminating the need for manual inspection and associated accountability issues
Solution Approach 2:
The patent replaces the manual mechanical inspection process with an automated electronic system that uses magneto-optical imaging and computer-based image analysis to perform security checks, substituting human operators with automated technological systems
3Ease of operation
If traditional security devices are used, then basic detection can be performed, but they cannot be integrated with gate machine control systems, unattended access control cannot be achieved, and history of passages is not recorded
Solution Approach 1:
The patent merges the security detection system with the access control gate machine into an integrated system. The control system receives detection results and automatically controls the gate machine to open or close, combining two previously separate functions into one unified system that achieves unattended access control
Solution Approach 2:
The system implements feedback by recording passage history and using detection results to automatically control gate machine operation. The control system receives real-time detection information and provides feedback control signals to the gate machine, creating a closed-loop automated access control system
