Solution Overview
Problem
Existing methods for detecting hidden or concealed explosives and contraband in shoes lack efficiency and accuracy, and cause inconvenience to customers undergoing inspection.
Innovation Solution
A shoe inspection apparatus that uses electromagnetic waves (millimeter and terahertz waves) to scan for hidden substances, combined with fluid injection and suction to remove moisture and separate materials for analysis, utilizing an Ion Mobility Spectrometer (IMS) for detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electromagnetic wave scanning is used to detect hidden substances in shoes, then detection capability is improved, but inspection time and process complexity increase
Solution Approach 1:
The system performs fluid injection and suction operations before electromagnetic wave scanning to remove moisture and foreign substances from the shoe. This preliminary preparation eliminates interference that would otherwise require repeated scanning attempts, thereby reducing total inspection time while maintaining high detection capability through the subsequent electromagnetic wave scan.
2Measurement precision
If fluid injection and suction are added to remove moisture and foreign substances, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent combines fluid injection, fluid suction, and electromagnetic wave scanning functions into a single integrated inspection apparatus. The injection unit, suction unit, and transmission/reception units are merged into one system that performs multiple functions simultaneously or sequentially, thereby improving detection accuracy without proportionally increasing overall device complexity.
Solution Approach 2:
The inspection apparatus is designed as a multi-functional system that can perform moisture removal, foreign substance removal, and hidden substance detection within a single device. This universal design allows one apparatus to handle multiple inspection tasks that would otherwise require separate devices, balancing enhanced detection accuracy with reasonable device complexity.
3Reliability
If comprehensive inspection including moisture removal is performed, then inspection quality is improved, but ease of operation decreases
Solution Approach 1:
The system performs fluid injection and suction operations automatically without requiring manual intervention from the operator. The apparatus self-manages the moisture and foreign substance removal process, maintaining high inspection quality while preserving ease of operation through automated execution of complex procedures.
