Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If laboratory-based or contact-based detection techniques are used, then measurement precision can be achieved, but the system cannot be used in field operations or at large public events due to inability to maintain safe standoff distances
Solution Approach 1:
The patent replaces mechanical contact-based detection systems with electromagnetic radiation-based detection. The sensor system collects electromagnetic radiation (millimeter-wave, terahertz, and infrared) from the region of interest, enabling non-contact detection from safe distances while maintaining detection accuracy through spectral analysis of the collected radiation
Solution Approach 2:
The patent introduces electromagnetic radiation as an intermediary between the detector and the concealed material. The radiation penetrates intervening materials such as clothing and atmospheric conditions to carry information about the concealed dielectric material to the sensor system, enabling detection without direct contact
2Reliability
If conventional detection techniques are used, then detection capability is maintained, but the system cannot penetrate intervening materials such as clothing and atmospheric conditions
Solution Approach 1:
The patent employs a multi-functional sensor system capable of collecting electromagnetic radiation across multiple frequency bands (millimeter-wave, terahertz, and infrared). This universal approach allows the system to penetrate various intervening materials including clothing and atmospheric conditions while maintaining reliable detection of concealed materials
Solution Approach 2:
The patent changes the operational parameters by utilizing electromagnetic radiation at different frequency bands. By collecting radiation across millimeter-wave, terahertz, and infrared spectra, the system adapts to penetrate different types of intervening materials, with each frequency band offering different penetration characteristics
3Measurement precision
If multi-frequency radiation collection is implemented, then material identification accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple detection functions into a single integrated sensor system. The sensor system simultaneously collects millimeter-wave, terahertz, and infrared radiation, combining multiple detection capabilities into one unified apparatus that identifies materials through综合分析 of radiation across all frequency bands
