Problem
There is a growing concern for air quality in activity spaces due to harmful gases such as particulate matter, carbon dioxide, and volatile organic compounds, which existing technologies have not effectively addressed in terms of real-time monitoring and rapid purification.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a purification unit with multiple filtering components is installed, then the air purification capability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple purification functions (particulate filtration, photo-catalytic decomposition, negative ion generation) into a single integrated purification unit that processes gas flow through sequential stages, reducing the need for separate devices while maintaining comprehensive air cleaning capability
Solution Approach 2:
The purification unit is designed to perform multiple functions simultaneously: the HEPA filter captures particles, the photo-catalyst decomposes organic compounds, and the negative ionizer generates ions for further purification, allowing one device to address multiple air quality issues
2Speed
If real-time gas detection and rapid purification are implemented, then the response speed to air quality changes is improved, but the device complexity increases
Solution Approach 1:
The gas detection main body continuously monitors air quality parameters and provides real-time feedback to the driving controller, which automatically adjusts the purification unit's operation intensity and airflow rates, creating a closed-loop system that responds dynamically to air quality changes
Solution Approach 2:
The system automatically detects air quality conditions and self-regulates the purification process without manual intervention, with the driving controller managing the enablement and disablement of various components based on real-time sensor data
