Solution Overview
Problem
Current detection systems for unauthorized objects or materials in protected areas, such as metal detectors and body scanners, face challenges in efficiently processing high volumes of individuals, particularly in public places like stadiums or large theaters, where the flow rate is insufficient due to the need for prolonged scanning times.
Innovation Solution
A dual-column system with inductive and microwave detection technology that uses the movement of individuals through a channel to emit and detect magnetic and microwave fields, allowing for simultaneous analysis of metallic and dielectric objects, enabling rapid and precise identification of objects regardless of their location on the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If body scanners use microwave transducers to detect objects on individuals, then detection precision is improved, but scanning time increases significantly
Solution Approach 1:
The system transitions from static scanning (where individuals must remain stationary for several seconds) to dynamic scanning (where individuals walk through the channel at normal speed). The microwave transducers continuously track and analyze objects during movement, maintaining detection precision while reducing scanning time from several seconds to a rapid pass-through process.
Solution Approach 2:
The system performs preliminary spatial mapping of the channel and establishes tracking algorithms before individuals enter. As individuals move through the channel, the system has pre-configured transducer arrays and processing routines ready to immediately detect and track objects, eliminating the need for prolonged stationary scanning and enabling rapid sequential processing of multiple individuals.
2Reliability
If body scanners perform detailed analysis of each individual, then detection reliability is improved, but throughput decreases to a level insufficient for high-traffic areas
Solution Approach 1:
The detection process is segmented into multiple independent stages: initial object detection, spatial location determination, material classification, and threat assessment. Each stage processes specific aspects of the scan independently, allowing parallel computation and reducing the total time required for complete analysis while maintaining comprehensive detection coverage.
Solution Approach 2:
The system maintains continuous detection and analysis throughout the individual's passage through the channel, rather than performing discrete sequential scans. Multiple microwave transducers continuously emit and receive signals as the individual moves, enabling uninterrupted object tracking and real-time analysis, which increases throughput while maintaining detection reliability through constant monitoring.
