Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional air purifiers operate without real-time remaining time display, then the device complexity is reduced, but the user satisfaction and air pollution control effectiveness deteriorate
Solution Approach 1:
The system implements real-time feedback by continuously monitoring air quality parameters (PM2.5, PM10, temperature, humidity) and displaying remaining purification time to users. This feedback loop allows users to understand the purification progress and adjust settings accordingly, significantly improving user satisfaction and air pollution control effectiveness.
Solution Approach 2:
The system performs preliminary calculations of purification duration based on current air quality and target standards before starting purification. By pre-calculating the remaining time needed to achieve air quality targets, the system provides users with advance information about purification completion, enhancing ease of operation without requiring complex real-time adjustments during purification.
2Reliability
If the air purifier calculates and displays real-time remaining time, then the air pollution control effectiveness is improved, but the use of energy increases due to continuous monitoring and calculation
Solution Approach 1:
The system employs periodic monitoring and calculation cycles rather than continuous operation. Air quality parameters are sampled at predetermined intervals, and remaining time is recalculated periodically based on these samples. This periodic approach maintains reliable air pollution control effectiveness while significantly reducing energy consumption compared to continuous monitoring and calculation.
3Measurement precision
If the system monitors multiple air quality parameters in real time, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The system achieves multi-functionality by integrating multiple air quality monitoring functions (PM2.5, PM10, temperature, humidity sensing) into a single unified control device. This universal approach allows precise measurement of multiple parameters simultaneously while avoiding the complexity of separate monitoring systems, as all functions share common processing and control resources.
