Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional filtration is used, then airborne particulates can be captured, but specific types of particulates cannot be detected
Solution Approach 1:
The patent combines filtration and detection functions into a single integrated system. The filter collects airborne particulates while the colorimetric sensor array simultaneously detects specific types of particulates by measuring color changes resulting from chemical reactions between the particulates and sensor reagents.
Solution Approach 2:
The filter system performs multiple functions: it filters airborne particulates from the air stream and simultaneously detects specific types of particulates using colorimetric sensors. This multi-functional approach allows a single device to both capture and identify hazardous substances.
2Productivity
If conventional filters are used, then air can be filtered, but real-time detection of particulates is not provided
Solution Approach 1:
The filter is pre-equipped with colorimetric sensor arrays that are prepared in advance to detect specific particulates. The sensors contain reagents that will react with target substances, enabling immediate detection when particulates are captured without requiring additional processing steps.
Solution Approach 2:
The detection mechanism relies on colorimetric changes that occur when sensor reagents react with specific airborne particulates. These color changes can be visually observed or measured instrumentally, providing real-time feedback on the presence and concentration of hazardous substances.
3Loss of information
If non-specific filtration is used, then general particulates can be captured, but specific types cannot be identified
Solution Approach 1:
Different regions of the filter are equipped with specific colorimetric sensors designed to detect different types of particulates. Each sensor location has specialized reagents that react with particular substances, allowing spatially distributed detection of multiple particulate types across the filter surface.
