Solution Overview
Problem
Existing air quality monitoring systems are unable to provide real-time detection of air pollution, especially suspended particles and other harmful gases, due to unstable gas flow and fixed monitoring stations, posing health risks and difficulty in maintaining indoor air quality.
Innovation Solution
A mountable gas exchange device equipped with a gas detector, air guiding fan, filter component, and driving controller, connected to a networked cloud computing service via IoT, allowing for intelligent air pollution detection and purification by introducing outdoor air through multiple filtration cycles and temperature adjustment, maintaining a positive pressure to prevent outdoor pollution from entering the indoor space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed gas-quality monitoring station is used, then the monitoring location is stable, but the gas flow becomes unstable due to variable wind direction and air volume, making real-time detection impossible
Solution Approach 1:
The patent transforms the fixed monitoring station into a movable, portable device that can be dynamically positioned and deployed. The gas quality monitoring device is designed to be mobile rather than fixed, allowing it to adapt to different locations and environmental conditions, thereby resolving the contradiction between location stability and real-time detection capability.
2Quantity of substance
If outdoor air is introduced for ventilation, then indoor air quality can be improved, but outdoor air pollution may enter the indoor field
Solution Approach 1:
The patent applies preliminary action by filtering outdoor air through multiple filtration stages (including HEPA filters and activated carbon filters) before it enters the indoor environment. This pre-processing of the air ensures that pollutants are removed in advance, allowing ventilation to occur without introducing harmful substances indoors.
Solution Approach 2:
The patent introduces filtration systems as intermediary components between the outdoor air source and the indoor environment. These filters act as mediators that selectively allow clean air to pass while blocking pollutants, thus enabling air exchange without direct exposure to outdoor contamination.
3Manufacturing precision
If multiple filtration cycles are performed, then air purification effectiveness is improved, but energy consumption and operation time increase
Solution Approach 1:
The patent employs multiple filtration stages in sequence, where each filter handles specific types of pollutants. Rather than using one overly complex filter, the system uses a series of specialized filters (partial action on different pollutant types), achieving comprehensive purification while optimizing energy use by matching filter capacity to actual pollution levels.

AI summary
A mountable gas exchange device used in an indoor air cleaning network mechanism is provided and includes a detector (1) and a gas exchange main part (2). The gas exchange main part (2) is built-in and suspended in the indoor field (A) and comprises an air guiding fan (21), a filter component (22), a driving controller (23) and a flow guiding pathway (24). The flow guiding pathway (24) has a gas introducing entrance (24a), a gas exchange fan (25) is arranged at the gas circulation entrance (24a). The gas detector (1) controls the actuation operation of the air guiding fan (21) and the gas exchange fan (25) through the Internet of Things communication. Consequently, air in the outdoor field (B) is introduced into the indoor field (A) through the filter duct (24c), and air in the indoor field (A) enters the filter duct (24c) through the circulating return air port (24b) for multiple cycles of filtration to air pollution purification.
