Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional swab chemical test or microscopy techniques are used to detect virus and bacteria particles, then detection accuracy can be achieved, but real-time visualization capability is lost and detection time increases
Solution Approach 1:
The patent replaces mechanical contact-based detection methods (swabbing, physical microscopy) with electromagnetic wave-based detection. Millimeter wave and terahertz signals are transmitted to interact with ionic particles, triggering resonant frequencies that are detected and visualized in real-time, eliminating the need for physical contact and lengthy laboratory procedures
Solution Approach 2:
The patent employs visual representation where different colors indicate the presence and type of particles. The system generates visual outputs that color-code detected particles, enabling immediate visual identification and differentiation of virus and bacteria particles without requiring complex microscopic analysis
2Reliability
If contact-based detection methods are used, then particle presence can be confirmed, but real-time visualization and immediate response capability are prevented
Solution Approach 1:
The system replaces mechanical swabbing and sample collection with contactless electromagnetic radiation. Millimeter wave and terahertz signals penetrate and interact with particles on surfaces, triggering resonant responses that are immediately detected and visualized, enabling rapid detection without physical contact
Solution Approach 2:
The system performs preliminary detection by scanning surfaces with electromagnetic waves before contamination spreads or requires physical intervention. The resonant frequency detection occurs immediately upon particle presence, enabling preemptive identification and response
3Measurement precision
If expensive equipment like electron microscopy is used, then high-resolution detection is achieved, but device complexity and cost increase
Solution Approach 1:
The patent substitutes complex mechanical microscopy systems with electromagnetic wave transmission and reception. The system uses millimeter wave and terahertz signals that naturally interact with ionic particles, requiring only transmitters, receivers, and signal processing equipment rather than complex optical or electron microscopy apparatus
Solution Approach 2:
The system changes the detection parameter from visual/optical properties to electromagnetic resonant frequency properties. By detecting the natural resonant frequencies of ionic particles in the millimeter wave and terahertz range, the system achieves particle identification through frequency analysis rather than complex imaging

AI summary
Visualizing the presence of virus and/or bacteria particles on a surface is described. This includes transmitting one or more millimeter wave and/or terahertz output signals toward the surface. The one or more output signals may trigger a resonant frequency of an ionic electrically charged particle with an electro-chemical valence shell on the surface, such as a virus particle or a bacteria particle. Or the one or more output signals may be absorbed by such a particle. A location of the particle is determined based on a triggered frequency dependent electromagnetic response received from the particle, or a relative lack of received energy at one or more frequencies of the output signals absorbed by the particle. A visual representation of the particle on the surface is generated based on the location.
