Indoor air pollution prevention system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indoor air purification systems fail to effectively eliminate hazardous gases such as carbon monoxide and carbon dioxide, and struggle to monitor and improve indoor air quality due to poor air circulation and mixed outdoor and indoor pollution sources.
Innovation Solution
An indoor air pollution prevention system with gas detection modules, intelligent control-driving processing devices, and gas-exchange processing devices that selectively exchange and filter polluted indoor air, using a combination of intake and discharge passages and cleaning and filtration assemblies to purify and discharge harmful gases to outdoor spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air conditioners or air cleaners are used for indoor circulation, then air circulation is improved, but hazardous gases such as carbon monoxide and carbon dioxide cannot be eliminated
Solution Approach 1:
The patent extracts and removes hazardous gases from the indoor air circulation system by introducing a dedicated gas discharge passage that selectively extracts harmful gases (carbon monoxide, carbon dioxide, formaldehyde) from the indoor environment and discharges them to the outdoor space, separating the harmful gas removal function from the general air circulation function
Solution Approach 2:
The patent segments the air treatment function into two independent pathways: an intake passage for bringing in outdoor air and a discharge passage for removing hazardous indoor gases. This segmentation allows the system to simultaneously achieve fresh air intake and harmful gas removal without mixing the two functions in a single circulation loop
2Measurement precision
If gas detection modules and intelligent control systems are added, then gas quality monitoring is improved, but device complexity increases
Solution Approach 1:
The gas detection modules are integrated directly into the air handling system components (air conditioner or air cleaner), allowing the system to autonomously monitor gas quality and trigger discharge operations when hazardous gas levels are detected, eliminating the need for separate external monitoring systems
Solution Approach 2:
The intelligent control system continuously receives feedback from gas detection modules monitoring indoor air quality parameters (carbon monoxide, carbon dioxide, formaldehyde levels) and automatically adjusts the discharge passage operation accordingly, creating a closed-loop control system that responds dynamically to gas quality conditions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively reduces indoor air pollution by filtering and exchanging hazardous gases, ensuring air quality meets safety standards by continuously monitoring and adjusting to maintain clean air conditions, thereby reducing health risks from inhaling pollutants.
Implementation Method 1
the air pollution source in the indoor space passes through a cleaning and filtration assembly in the discharge passage and is discharged to the outdoor space, allowing the air pollution source in the indoor space to be filtered and exchanged to become a clean air

AI summary
An indoor pollution prevention system includes a plurality of gas detection modules (4), one or more intelligent control-driving processing devices (5), one or more gas-exchange processing devices (1), one or more intake passages (2), and one or more discharge passages (3). The intake passage (2) is connected to the gas-exchange processing device (1) and has an intake opening (2a) for guiding the outdoor gas into an indoor space (A). The discharge passage (3) is connected to the gas-exchange processing device (1) and has a discharge opening (3a) for discharging the air pollution source to an outdoor space (B). The intelligent control-driving processing device (5) controls the gas-exchange processing device (1) to be enabled under a surveillance condition of the gas detection module (4), so that the air pollution source passes through the discharge passage (3), filtered and purified by a cleaning and filtration assembly (D), and is discharged to the outdoor space (B), thereby allowing the indoor space (A) to have a clean air.
