Gate Device Dual-Side Sensing for Fraud Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gate devices lack efficient mechanisms for detecting individuals passing through, particularly in secure facilities like airports, where both front and rear passage monitoring are crucial for security and fraud prevention.
Innovation Solution
A gate device is designed with a gate main body, shutters, and a structure featuring first and second sensing devices on the upper surface and side, respectively, to monitor and control passage, integrating face recognition and fraud detection capabilities, ensuring efficient passage management and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensing devices are disposed only on the front side of the gate main body, then the structure is simple, but persons passing through the rear side cannot be detected
Solution Approach 1:
The patent applies dimensionality change by extending the sensing coverage from a single side (front) to multiple dimensions (front and rear sides) of the gate main body. By disposing sensing devices on both the front surface and rear surface, the system achieves three-dimensional coverage of passage detection, eliminating blind spots and improving detection reliability without excessive complexity.
2Reliability
If sensing devices are disposed on both front and rear sides, then passage detection is improved, but the device structure becomes complex
Solution Approach 1:
The patent applies multi-functionality by designing the sensing devices to perform multiple functions: detecting persons passing through the gate, identifying fraudulent behaviors (such as tailgating or unauthorized passage), and providing comprehensive security monitoring. This unified approach allows a single sensing system to handle various detection needs without requiring separate specialized devices for each function.
Solution Approach 2:
The patent combines the sensing devices with the gate main body structure, integrating the detection functionality into the existing gate framework. By merging the sensing components with the gate structure rather than adding separate standalone detection systems, the patent achieves improved fraud detection capability while minimizing structural complexity.
3Measurement precision
If multiple sensing devices are added for comprehensive detection, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The patent applies local quality by strategically positioning sensing devices at specific locations on the gate main body (front surface and rear surface) where they can most effectively detect persons and fraudulent behaviors. Rather than uniformly distributing sensors throughout the entire structure, the sensing devices are placed at critical points that provide optimal detection accuracy with minimal device complexity.

AI summary
A gate device disposed between a first space where a person waiting for passing through exists and a second space where a person already passed through exists, the device including: a gate main body disposed along a path through which the person existing in the first space passes when the person moves to the second space; a shutter for blocking or opening the path; and a structure disposed on an upper surface of the gate main body and having a first sensing device for sensing a person passing through the path, and a second sensing device for sensing a person passing through a side opposite to the path across the gate main body.
