A terahertz security inspection robot equipped with a terahertz wave imaging mechanism, a rotating mechanism, and a visible light imaging mechanism, which allows for non-contact, multi-directional scanning and imaging of objects, enabling the detection of various threats without physical contact or radiation, and integrating data processing to determine the presence and nature of suspect items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection is used, then inspection accuracy is improved, but inspection efficiency deteriorates
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated terahertz wave imaging system. The robot uses terahertz waves to automatically scan and image objects, eliminating the need for manual inspection while maintaining high detection accuracy for various materials including metals, liquids, and organic substances.
2Measurement precision
If hand-held metal detectors or metal detection doors are used, then metal detection capability is improved, but detection of non-metal dangerous objects deteriorates
Solution Approach 1:
The patent employs a terahertz wave imaging mechanism that can detect multiple types of materials simultaneously - metals, non-metals, liquids, and organic substances. This multi-functional detection capability replaces the single-function metal detectors with a universal system that identifies all dangerous objects regardless of material composition.
3Measurement precision
If X-ray machines are used, then detection capability is improved, but safety concerns and public acceptance deteriorate
Solution Approach 1:
The patent changes the detection parameter from ionizing X-rays to non-ionizing terahertz waves. This parameter change maintains detection capability while eliminating the harmful ionization effects, making the system safer for public use and improving public acceptance.
4Ease of manufacture
If existing detectors are used, then single-function detection is achieved, but multi-functional inspection capability deteriorates
Solution Approach 1:
The patent integrates multiple detection functions into a single terahertz wave imaging system. The system can detect metals, non-metals, liquids, and organic substances simultaneously, providing multi-functional inspection capability while maintaining system simplicity through unified hardware architecture.
