Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional air conditioners or air cleaners are used to improve indoor air quality, then air filtering is provided, but the system cannot quickly locate and remove air pollution sources, resulting in slow response time and inability to rapidly clean polluted air
Solution Approach 1:
The system divides the indoor space into multiple detection zones with several gas detection devices distributed throughout. Each device independently monitors its local area, enabling the system to segment the monitoring task and quickly identify which specific zone is polluted, thereby locating the pollution source rapidly without waiting for a single centralized device to detect it.
Solution Approach 2:
The control central processor receives real-time pollution data from gas detection devices and continuously adjusts the operation of filtering devices based on the detected pollution levels and locations. This feedback mechanism enables dynamic response to changing air quality conditions, allowing the system to quickly intensify filtering operations when pollution is detected and maintain optimal air quality.
2Reliability
If multiple filtering devices are deployed throughout the indoor space, then the ability to filter air pollution at various locations is improved, but the system complexity and cost increase
Solution Approach 1:
The system dynamically adjusts which filtering devices operate based on real-time pollution detection. Instead of having all filtering devices run continuously or requiring complex permanent configuration, the control central processor activates specific filtering devices only when and where pollution is detected, making the system adaptable and reducing unnecessary complexity.
Solution Approach 2:
The filtering devices are designed to be multi-functional, serving both as air cleaners and as part of the intelligent response system. The same devices that filter air are controlled by the central processor to respond to detected pollution, eliminating the need for separate control mechanisms and reducing overall system complexity while maintaining comprehensive filtering capability.
3Measurement precision
If gas detection devices are used to detect air pollution, then pollution location and concentration can be identified, but without intelligent control, the filtering devices cannot efficiently target and remove the detected pollution
Solution Approach 1:
The control central processor uses the precise pollution location and concentration data from gas detection devices to make intelligent decisions about which filtering devices to activate and at what intensity. This feedback loop ensures that filtering resources are efficiently allocated to the specific areas and types of pollution detected, maximizing pollution removal efficiency based on accurate measurement data.
Solution Approach 2:
The system changes operational parameters of filtering devices based on the detected pollution characteristics. When high concentrations of specific pollutants are detected, the control processor adjusts the filtration intensity, activates additional filtering devices, or changes the operational mode of existing devices to match the pollution severity and type, thereby optimizing removal efficiency according to the precise measurements obtained.

Function Achieved in This Case
The system rapidly filters indoor air pollutants to nearly undetectable levels, ensuring a safe and breathable indoor environment by intelligently guiding and accelerating pollutant removal through directed air convection and filtering.
Implementation Method 1

AI summary
A system for detecting and cleaning indoor air pollution adapted to be utilized in an indoor space with an HVAC system includes one or more outdoor gas detection devices, a plurality of channels, a plurality of indoor gas detection devices, a plurality of physical-typed or chemical-typed filtering devices, and a control central processor. The blower of the filtering device receives a control command so as to be driven and to generate an air convection which is directed. Therefore, the air pollution is filtered by the filtering component to allow the indoor air pollution data to approach to almost zero, so that a gas in the indoor space is cleaned to a safe and breathable state.
