Solution Overview
Problem
Current security systems in high-density environments lack an integrated solution for automatic, real-time screening of both metallic threats and fever, leading to bottlenecks in access control and inefficient detection of non-metallic dangers and health risks.
Innovation Solution
An integrated access gateway combining a standard walkthrough metal detector with a noncontact fever detection system, thermal imaging, IP cameras, voice announcement, and SIP gateway for dynamic, real-time screening and individual identification, providing alarms and information on denied access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate screening devices (metal detectors and thermal scanners) are used, then detection capability is improved, but access flow efficiency deteriorates due to bottlenecks
Solution Approach 1:
The patent combines metal detection and thermal imaging capabilities into a single integrated access gateway structure. The metal detector gates and thermal imaging devices are merged into one physical unit, allowing simultaneous screening for both metallic threats and fever without requiring separate inspection stations, thereby eliminating bottlenecks and improving access flow efficiency while maintaining comprehensive detection capability
2Reliability
If manual searching of subjects is performed, then detection of concealed objects is improved, but screening speed deteriorates
Solution Approach 1:
The patent replaces manual searching with automated detection systems. Metal detectors use electromagnetic fields to automatically detect metallic objects, and thermal imaging devices use infrared radiation to automatically detect fever. These automated systems eliminate the need for slow manual inspection while maintaining or improving detection reliability for concealed threats and health conditions
3Productivity
If noncontact thermal screening is used, then hygiene and speed are improved, but measurement precision deteriorates due to wide angle of view
Solution Approach 1:
The patent applies local quality by focusing the thermal imaging device on specific high-value areas such as the forehead or eye region for temperature measurement. The system concentrates thermal detection on localized regions with reliable temperature indicators rather than attempting to measure the entire body, thereby achieving accurate temperature readings through focused detection of thermally distinctive local areas
4Extent of automation
If integrated access gateway is implemented, then automation and efficiency are improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing the access gateway to perform multiple screening functions within a single integrated structure. The system combines metal detection, thermal imaging, and access control capabilities in one device that can screen for both security threats and health conditions simultaneously, thereby achieving high automation and efficiency while managing complexity through functional integration rather than separate systems
