Modular Window Ventilation Filter Frame for Fine Dust Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation systems for windows and doors struggle to effectively ventilate indoor air due to outdoor air pollution, which can worsen indoor air quality and lead to health issues, as they often fail to manage fine dust and other contaminants effectively.
Innovation Solution
An assembly-type ventilation device installed between windows and window frames, featuring a filter frame with adjustable size, a ventilation module with a fine dust sensor, and a solar-powered fan that adjusts ventilation speed based on real-time indoor and outdoor air quality measurements, using detachable air filters to manage indoor air quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If outdoor air is used for ventilation, then indoor air quality can be improved through fresh air supply, but fine dust and contaminants from polluted outdoor air can enter and worsen indoor air quality
Solution Approach 1:
The patent introduces an air filter as an intermediary component between the outdoor air source and the indoor environment. The filter frame with detachable air filter modules captures and removes fine dust and contaminants from outdoor air before it enters the indoor space, allowing ventilation to proceed without introducing harmful particles.
Solution Approach 2:
The ventilation system is divided into separable components: a fixed filter frame and detachable air filter modules. This segmentation allows the filter to be easily replaced or maintained without removing the entire ventilation system, ensuring continuous operation while maintaining air quality.
2Ease of operation
If a fixed ventilation system is installed, then ventilation function is provided, but adaptability to windows of various sizes is reduced
Solution Approach 1:
The filter frame is designed with adjustable dimensions that can be modified to fit different window sizes. The detachable air filter modules can be configured in various arrangements, allowing the ventilation system to adapt to diverse window configurations while maintaining its ventilation function.
Solution Approach 2:
The ventilation device is designed as a universal system that can be installed on windows of various sizes and configurations. The adjustable filter frame and modular air filter design enable a single product to serve multiple window types, increasing versatility without compromising ventilation effectiveness.
3Ease of operation
If continuous ventilation is performed, then indoor air quality is maintained, but energy consumption increases due to fan operation
Solution Approach 1:
Instead of continuous fan operation, the system uses periodic ventilation cycles controlled by a timer or sensor. The fan operates intermittently to maintain acceptable indoor air quality levels, reducing energy consumption while still effectively removing contaminants and maintaining air freshness.
Solution Approach 2:
The ventilation system incorporates sensors that monitor indoor air quality parameters such as CO2 levels, particulate matter, or temperature. Based on this feedback, the fan operation is automatically adjusted - increasing ventilation when air quality deteriorates and reducing or stopping operation when air quality is acceptable, optimizing energy usage.
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 device effectively filters and ventilates indoor air by discharging pollutants and managing fine dust levels, improving indoor air quality and user satisfaction by providing stable and controlled ventilation, even on windows of various sizes.
Implementation Method 1
a fine dust measurement part movably installed along a rail inside the frame while being inserted inside the ventilation frame, and installed therein with a fine dust sensor to control and drive the ventilation fan when fine dust contained in outside air is less than a set concentration or fine dust in indoor air is higher than the set concentration
Implementation Method 2
a ventilation fan installed in the ventilation frame
Implementation Method 3
a plurality of air filters inserted and fixed to the module frame
