Engineering Contradiction Analysis
1Productivity
If air conditioners or air cleaners are used for indoor gas circulation, then indoor gas circulation is improved, but hazardous gases (carbon monoxide or carbon dioxide) cannot be eliminated
Solution Approach 1:
The patent extracts the gas exchange function from traditional air conditioners and air cleaners by introducing a dedicated gas exchanger that specifically targets hazardous gas removal. The gas exchanger is configured to detect hazardous gases (carbon monoxide, carbon dioxide) and selectively exchange indoor air with outdoor air, separating the gas exchange function from general air circulation functions.
Solution Approach 2:
The system integrates multiple functions into a unified platform: the gas exchanger simultaneously performs hazardous gas detection, air quality monitoring, and conditional gas exchange. The controller coordinates multiple components (detectors, exchanger, filters) to achieve both air circulation and hazardous gas elimination, making the system versatile in addressing multiple air quality issues.
2Object-affected harmful factors
If outdoor gas is introduced into indoor space for gas exchange, then indoor air quality can be improved, but pollution may be introduced when outdoor air quality is poor
Solution Approach 1:
The system performs preliminary detection of outdoor air quality before initiating gas exchange. Outdoor air quality detectors measure parameters such as PM2.5, PM10, and other pollutants in advance. The controller uses this pre-detected information to determine whether outdoor air is suitable for introduction, preventing pollution from being brought indoors when outdoor conditions are poor.
Solution Approach 2:
The system continuously monitors both indoor and outdoor air quality parameters and uses this feedback to dynamically control the gas exchanger operation. When outdoor air quality deteriorates, the system receives feedback signals and automatically adjusts or stops gas exchange operations. The feedback mechanism ensures real-time adaptation to changing environmental conditions, maintaining indoor air quality safety.
3Reliability
If real-time monitoring and control of gas quality is implemented, then air quality safety is improved, but system complexity increases
Solution Approach 1:
The monitoring and control system is segmented into independent functional modules: outdoor air quality detectors, indoor air quality detectors, gas exchanger, filters, and controller. Each module performs a specific function and can be independently configured or maintained. This modular segmentation reduces overall system complexity by making each component simpler and more specialized.
Solution Approach 2:
The system incorporates automatic control capabilities where the controller autonomously processes detection data from multiple sensors and adjusts gas exchanger operation without human intervention. The system self-regulates based on pre-set criteria and real-time sensor feedback, reducing the need for complex manual control mechanisms and simplifying operation while maintaining high reliability.

AI summary
A method for intelligently preventing and handling indoor air pollution is adapted to be implement in an indoor space. The method includes providing an outdoor gas detector to detect a polluted gas in an outdoor space and transmit an outdoor gas detection data; providing an indoor gas detector to detect a polluted gas in the indoor space and transmit an indoor gas detection data; and providing an indoor gas exchange system including a gas exchanger. The gas exchanger compares the outdoor gas detection data with the indoor detection data and controls the polluted gas in the indoor space to determine if the gas exchange function should be performed. Therefore, the indoor gas detection data of the polluted gas in the indoor space is decreased to a safety detection value and the polluted gas in the indoor space becomes a clean, safe, and breathable gas.
