Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional air purification methods are used, then air quality improves gradually, but the purification speed is slow and cannot achieve near-zero pollution levels quickly
Solution Approach 1:
The system performs preliminary detection of air pollution sources and locations before initiating purification. Gas detection devices continuously monitor and identify pollution sources, allowing the system to pre-position air-exchanging filtration devices at optimal locations before pollution levels become critical, enabling faster response and more efficient purification to near-zero levels
Solution Approach 2:
The indoor space is divided into multiple monitoring zones with distributed gas detection devices. Each zone independently detects and reports pollution levels, allowing parallel purification operations in multiple locations simultaneously. This segmentation enables the system to process and purify air from different pollution sources concurrently, dramatically increasing overall purification speed while maintaining reliable safety levels across the entire space
2Reliability
If multiple air-exchanging filtration devices are deployed throughout the indoor space, then air purification effectiveness improves, but system complexity and cost increase
Solution Approach 1:
Air-exchanging filtration devices are strategically positioned based on local pollution detection data rather than uniform distribution. The system concentrates filtration resources in areas with detected pollution sources, achieving high purification effectiveness where needed while avoiding unnecessary devices in clean areas, thus reducing overall system complexity while maintaining reliability
Solution Approach 2:
The system implements continuous feedback through gas detection devices that monitor air quality in real-time and automatically adjust the operation status of air-exchanging filtration devices. When pollution is detected, the system activates nearby filtration devices; when air quality improves, devices are deactivated or reduced in operation. This feedback mechanism ensures effective purification while minimizing the number of devices needed at any given time, reducing system complexity
3Reliability
If real-time air quality monitoring and intelligent control are implemented, then air pollution can be purified to near-zero levels, but energy consumption and operational complexity increase
Solution Approach 1:
The system uses periodic detection cycles with gas detection devices that continuously monitor air quality and periodically update pollution source locations. Air-exchanging filtration devices operate in periodic cycles, activating when pollution is detected and deactivating when air quality reaches safe levels. This periodic operation maintains near-zero pollution levels through intelligent control while significantly reducing energy consumption compared to continuous operation
Solution Approach 2:
The system dynamically changes operational parameters of air-exchanging filtration devices based on real-time detection data. When pollution levels are high, devices operate at high airflow rates; when levels drop, airflow rates are reduced or devices are turned off. This parameter adjustment strategy maintains air quality safety levels while optimizing energy consumption by matching device operation intensity to actual pollution conditions
