Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional masks are used without sensors and calculation functions, then the device complexity is low, but the ability to quantify pollutant absorption is missing
Solution Approach 1:
A terminal device (smartphone, tablet, or computer) serves as an intermediary between the simple mask and the calculation system. The mask only collects basic data (wearing time, air quality index) while the terminal performs complex calculations involving respiratory volume and filtration efficiency to determine pollutant absorption quantity, thus avoiding embedding complex computation in the mask itself
Solution Approach 2:
The mask integrates multiple functions including pollutant filtration, wearing time recording, air quality monitoring, and data transmission, while the terminal device provides additional calculation and display functions. This distributed multi-functionality allows accurate quantification without making the mask itself overly complex
2Measurement precision
If the mask calculates pollutant absorption quantity using multiple parameters (wearing time, air quality index, respiratory volume, filtration efficiency), then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The terminal device acts as an intermediary that receives basic data from the mask and performs complex multi-parameter calculations. This separates the data collection function (simple mask) from the calculation function (terminal), reducing the complexity burden on the mask while maintaining high measurement precision
Solution Approach 2:
The system is segmented into two parts: the mask handles data collection (wearing time, air quality index), while the terminal handles data processing and calculation. This segmentation allows the complex calculation logic to be distributed to the terminal rather than embedded in the mask, reducing device complexity
3Loss of information
If the mask includes a sensor to record wearing time and connect to terminal for calculations, then the pollutant absorption quantity can be calculated, but the device complexity increases
Solution Approach 1:
The terminal device serves as an intermediary that receives minimal data from the mask and performs complex calculations to recover complete pollutant absorption information. This approach minimizes data loss while avoiding the need for complex sensors and processing units within the mask itself
