Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air conditioners or air cleaners are utilized for improving the indoor air quality, then the indoor air quality is improved, but the system cannot effectively and rapidly detect and control indoor air pollution sources
Solution Approach 1:
The system divides the indoor space into multiple monitoring zones with distributed gas detection devices, allowing parallel detection of pollution sources across different locations. This segmentation enables rapid identification of specific pollution sources without requiring a single complex detection system to scan the entire space sequentially.
Solution Approach 2:
The system implements real-time feedback through continuous monitoring of air quality parameters by gas detection devices, with the central control unit receiving data and immediately adjusting gas exchange and filtration device operations. This closed-loop feedback mechanism enables rapid response to pollution sources, automatically adjusting airflow and filtration based on detected pollutant levels.
2Measurement precision
If gas detection devices and control systems are deployed throughout the indoor space, then the detection capability is improved, but the device complexity increases
Solution Approach 1:
The gas detection devices are designed as multi-functional units that simultaneously detect multiple types of pollutants (particulate matters, CO2, TVOC, formaldehyde, bacteria, viruses) and integrate communication, data processing, and control signaling capabilities. This universality reduces the need for separate specialized devices for each function, thereby simplifying the overall system structure while maintaining comprehensive detection capability.
Solution Approach 2:
The system merges the detection, communication, and control functions into an integrated networked architecture where gas detection devices, central control unit, and gas exchange/filtration devices operate as a unified system. This consolidation of functions across components reduces individual device complexity while achieving sophisticated overall system performance through coordinated operation.
3Reliability
If multiple gas exchange and filtration devices are activated to filter pollutants, then the air quality is improved, but the energy consumption increases
Solution Approach 1:
The system activates only the necessary number of gas exchange and filtration devices based on real-time pollution detection, rather than running all devices continuously. The central control unit calculates the optimal activation strategy by comparing pollution levels against safety thresholds and determining the minimum required filtration capacity, thereby reducing energy consumption while maintaining air quality safety.
Solution Approach 2:
The system dynamically adjusts the operation of gas exchange and filtration devices based on varying pollution levels, outdoor air quality conditions, and indoor occupancy. The central control unit continuously modifies device activation and airflow rates in response to changing conditions, optimizing energy consumption while ensuring air quality remains within safe limits throughout the indoor space.
Applied Scientific Principles

Function Achieved in This Case
The system effectively locates and mitigates indoor air pollution sources, ensuring the air quality reaches safe and breathable levels by filtering pollutants, thereby improving indoor air quality and human health.
Implementation Method 1
The gas detection devices are configured to detect an air pollution in the indoor space. The gas detection devices comprise at least one outdoor gas detection device and at least one indoor gas detection device. The at least outdoor gas detection device and the at least one indoor gas detection device are configured to detect a qualitative property and a concentration of the air pollution
Implementation Method 2
Each of the gas exchange and filtration devices is combined with a smart switch, and the smart switch receives the control command to perform an adjusting and controlling mechanism, so that the air pollution is filtered and exchanged by the gas exchange and filtration devices
Implementation Method 3
The central control monitoring device selectively and intelligently transmits a control command to enable a gas exchange and filtration device closest to the air pollution location to generate an air flow to guide the air pollution to be filtered

AI summary
A system for cleaning, zeroing, and preventing air pollution in indoor space includes several gas detection devices (A, 3), a central control monitoring device (B), and several gas exchange and filtration devices (C).
