Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Indoor air pollution poses a significant threat to human health due to the presence of harmful gases and particles such as PM1, PM2.5, PM10, carbon dioxide, TVOC, formaldehyde, and bacteria, which can lead to serious health issues if not properly managed.
Innovation Solution
A method utilizing a portable gas detection device to monitor indoor air quality and remotely control a plurality of gas exchangers to purify the air. The gas exchangers include a purification unit combined with a gas guider, capable of exporting a gas at a specific airflow rate, ranging from 200 to 1600 CADR, to filter and purify the air, thereby reducing pollutants to safe levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple gas exchangers are deployed to rapidly purify indoor air, then air purification speed is improved, but device complexity and cost increase
Solution Approach 1:
The system divides the indoor space into multiple zones, each equipped with one or more gas exchangers. The portable detection device segments the monitoring function, allowing coordinated control of multiple exchangers based on detected pollutant levels in different areas. This segmentation enables rapid purification across the entire space while distributing the complexity across manageable units.
Solution Approach 2:
The system dynamically adjusts the operation of gas exchangers based on real-time air quality data from the portable detection device. When poor air quality is detected, multiple exchangers are activated; when air quality improves, they are deactivated or reduced in number. This dynamic control optimizes purification speed while minimizing the effective number of active devices, balancing productivity and complexity.
2Adaptability or versatility
If a portable gas detection device is used for real-time monitoring, then measurement flexibility is improved, but detection precision may be reduced compared to fixed installations
Solution Approach 1:
The portable gas detection device serves as a mobile intermediary between the indoor environment and the gas exchanger control system. It transmits real-time air quality data wirelessly to control the exchangers, enabling flexible monitoring while maintaining sufficient detection precision through coordinated operation with the purification system. The intermediary role allows the system to achieve both mobility and functional effectiveness.
