Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate screening steps and multiple pieces of equipment are used for specialized items like footwear, then detection capability for specific items is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple sensing technologies (millimeter wave scanner, metal detector, camera) into a single integrated security scanning system. The millimeter wave scanner, metal detector, and camera are all positioned within the same scanning region and controlled by a single controller, eliminating the need for separate screening equipment while maintaining comprehensive detection capabilities for various objects including footwear.
Solution Approach 2:
The integrated system performs multiple detection functions simultaneously using a single device. The millimeter wave scanner detects dielectric materials, the metal detector identifies metallic objects, and the camera captures visual information, all within one unified system that can screen for various types of concealed objects including weapons, drugs, and footwear-related threats.
2Reliability
If separate screening steps are implemented for specialized items, then detection accuracy for specific items is improved, but productivity and screening speed deteriorate
Solution Approach 1:
The system enables continuous simultaneous operation of multiple detection modalities. The millimeter wave scanner, metal detector, and camera all operate at the same time during a single screening event, eliminating the need for sequential separate screening steps. The controller coordinates all sensors to scan the scanning region concurrently, maintaining high detection accuracy while maximizing screening throughput.
Solution Approach 2:
The system performs preliminary detection using multiple sensors simultaneously before making a final determination. The millimeter wave scanner, metal detector, and camera all capture data during the same time window, allowing the controller to integrate information from all sources and make a comprehensive assessment in a single continuous scanning action.
3Measurement precision
If multiple sensors and separate screening processes are used, then detection accuracy is improved, but loss of time and operational efficiency worsen
Solution Approach 1:
The patent merges multiple detection systems into one integrated unit where the millimeter wave scanner, metal detector, and camera share a common scanning region and controller. This consolidation allows all sensors to operate simultaneously during a single screening event, reducing the total time required compared to sequential separate screening processes while maintaining high detection accuracy through multi-modal data fusion.
