Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large-scale environmental monitoring base station is used to monitor ambient air quality, then the monitoring coverage is limited to areas near the base station, but the monitoring accuracy in small areas with human activities is insufficient
Solution Approach 1:
The patent divides the air quality monitoring system into multiple distributed portable monitoring devices instead of relying on a single large-scale base station. Each portable device independently monitors air quality in its local vicinity, enabling comprehensive coverage of small areas with human activities while maintaining high measurement precision through proximity-based sensing
2Reliability
If air quality processing devices operate continuously to improve air quality, then the air quality improvement process is sustained, but energy consumption increases
Solution Approach 1:
The patent implements a feedback control mechanism where portable monitoring devices continuously detect air quality parameters and transmit data to a server. The server analyzes this data and provides feedback control signals to air quality processing devices, instructing them to operate only when air quality deteriorates and to stop when quality improves, thereby maintaining reliable air quality improvement while significantly reducing unnecessary energy consumption
3Productivity
If portable air quality monitoring devices are used, then real-time monitoring everywhere is enabled, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into integrated portable monitoring devices that include sensors for detecting air quality parameters, communication modules for data transmission, and processing units for local data analysis. This integration enables real-time monitoring everywhere while managing device complexity through functional consolidation and modular design
