Window-type smart air purifying ventilator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ventilation methods fail to effectively introduce fresh air into indoor spaces when outside air is polluted, leading to poor indoor air quality, and existing window-based solutions do not adequately address the need for automatic air purification and ventilation.
Innovation Solution
A window-type smart air purifying ventilator with a frame installed on a window frame, featuring multiple openings, a blowing part for air exchange, multilayer filters, and a control unit that compares indoor and outdoor air conditions to automatically control airflow, including sensors for temperature, humidity, and pollutant detection, and solar cell units for power generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If windows are opened for ventilation, then fresh air enters the indoor space, but polluted air also enters when outside air contains pollutants
Solution Approach 1:
The patent introduces a window-type air purifying ventilator as an intermediary device installed in the window frame. This device includes filters (HEPA, activated carbon) that mediate between the outdoor polluted air and the indoor environment, allowing air exchange while removing pollutants. The blowing part with fans actively draws air through the filters, creating a controlled pathway that separates the harmful outdoor air from the indoor space.
Solution Approach 2:
The ventilator applies local quality by concentrating air purification functionality at the window location rather than requiring a separate air purifier elsewhere in the room. The device creates a localized air treatment zone at the air exchange point, where filtration occurs precisely where outdoor air enters the indoor space, making the purification process more efficient and targeted.
2Object-affected harmful factors
If filters are installed on window frame temporarily, then fine dust is reduced when outside air enters, but ventilation efficiency is compromised
Solution Approach 1:
The patent replaces the passive mechanical system of simple filter installation with an active mechanical system incorporating blowing parts (fans). The fans actively draw air through the filters, creating sufficient airflow pressure to overcome filter resistance and maintain high ventilation efficiency. This active mechanical assistance ensures that air exchange rates remain high even with multiple filtration layers in place.
Solution Approach 2:
The window-type air purifying ventilator combines multiple functions into a single device: filtration (removing fine dust and pollutants), active air exchange (ventilation through blowing parts), and intelligent control (automatic operation based on air quality sensors). This multi-functional integration eliminates the need for separate temporary filter installations while maintaining both purification and ventilation efficiency.
3Object-affected harmful factors
If air purifier is separately installed and operated with windows closed, then fresh air is provided, but indoor air quality deteriorates due to lack of ventilation
Solution Approach 1:
The ventilator combines both air purification and ventilation functions in a single integrated device. The filtering part removes pollutants while the blowing part simultaneously provides active air exchange, replacing the need for separate air purifier and window ventilation operations. This dual functionality ensures both pollutant removal and fresh air supply occur together, maintaining indoor air quality without requiring windows to remain closed.
Solution Approach 2:
The device enables continuous air purification and ventilation through automated operation. Sensors continuously monitor air quality parameters (PM2.5, CO2, temperature, humidity), and the control unit continuously adjusts the blowing part operation to maintain optimal air exchange. This continuous active operation replaces the intermittent manual operations of closing windows and running separate air purifiers, ensuring uninterrupted air quality management.
4Object-affected harmful factors
If multiple filters are arranged in sequence, then air purification effectiveness increases, but device complexity increases
Solution Approach 1:
The filtration system is segmented into distinct functional layers: a HEPA filter layer for capturing fine dust particles (PM2.5, PM10) and an activated carbon filter layer for adsorbing gaseous pollutants and odors. This segmentation allows each filter type to specialize in removing specific pollutant categories, achieving comprehensive air purification while maintaining a manageable and organized filter structure that is easier to install and maintain than a single complex filter system.
