Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional floorplan-based models are used to map contagion spread, then the system complexity remains low, but the measurement precision of contagion spread through air and surfaces deteriorates
Solution Approach 1:
The patent replaces traditional mechanical/contact-based transmission models with thermal imaging-based detection. CO2 thermal depth cameras capture thermal signatures of exhaled breath, enabling non-contact, three-dimensional mapping of contagion aerosol dispersion through air and on surfaces, thereby achieving precise measurement without complex physical measurement devices
Solution Approach 2:
The patent changes the detection parameter from visible light to thermal infrared radiation. By detecting temperature differences in exhaled breath containing CO2 and aerosols, the system transforms the unobservable contagion spread into measurable thermal signals, achieving high measurement precision while maintaining manageable system complexity
2Measurement precision
If CO2 thermal depth imaging cameras are used to capture gaseous fluid flow, then the measurement precision of contagion source identification improves, but the device complexity increases
Solution Approach 1:
The patent employs CO2 thermal depth cameras that simultaneously perform multiple functions: detecting CO2 concentration, capturing three-dimensional spatial information, and visualizing thermal patterns of gaseous fluid flow. This multi-functionality achieves precise contagion source identification while avoiding the need for multiple separate specialized devices
Solution Approach 2:
The patent uses thermal depth imaging as an intermediary technique to indirectly detect contagion sources. Instead of directly measuring aerosol particles or viruses, the system detects thermal signatures of exhaled breath, providing precise source identification through a manageable intermediate measurement approach
3Measurement precision
If 3D density-flow representation is generated from image data, then the prediction accuracy of contagion flow patterns improves, but the processing complexity increases
Solution Approach 1:
The patent transforms two-dimensional camera images into three-dimensional density-flow representations by incorporating depth information from thermal depth imaging. This dimensional transformation enables accurate prediction of contagion flow patterns in three-dimensional space while utilizing standard image processing techniques adapted for volumetric data
