An air purifier comprising a diffuser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In closed environments like high-rise buildings, existing air purifiers are ineffective in maintaining adequate oxygen levels and reducing carbon dioxide concentrations, leading to adverse health effects due to the inability to continuously ventilate and the inefficiency in adsorbing CO2.
Innovation Solution
An air purifier design featuring a CO2 adsorption unit with a diffuser that uses a basic liquid solution to convert CO2 into carbonate, enhancing the reaction efficiency through bubble formation by mixing air with the solution, facilitated by a cylindrical diffuser with openings and a membrane with controlled pressure differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional filters (HEPA, UV) are used to clean air, then dust and bad odors are trapped, but carbon dioxide is not effectively removed and oxygen levels are not maintained
Solution Approach 1:
The patent changes the chemical state of the absorption medium from solid (conventional filters) to liquid (basic solution), enabling more effective CO2 removal through chemical reaction. The liquid basic solution reacts with CO2 to form carbonate, significantly improving adsorption efficiency compared to physical filtration methods
Solution Approach 2:
The patent introduces a diffuser system that creates bubbles by forcing air through a liquid medium. This hydraulic approach increases the contact surface area between CO2-containing air and the basic liquid solution, enhancing the rate and efficiency of CO2 absorption through improved mass transfer
2Quantity of substance
If windows are kept open for ventilation in high-rise buildings, then fresh air is supplied, but security and environmental control are compromised
Solution Approach 1:
The air purifier creates a self-contained ventilation system that does not require external window opening. The device autonomously absorbs CO2 and releases oxygen, maintaining air quality independently of external environmental conditions, thus providing both oxygen supply and operational flexibility
3Productivity
If basic liquid solution is used for CO2 absorption, then maximum CO2 adsorption is achieved, but the solution becomes carbonated and requires neutralization
Solution Approach 1:
The patent implements a regenerative system where carbonated basic solution is neutralized using acid to regenerate the basic solution. This allows the absorption medium to be reused multiple times, reducing waste and operational costs while maintaining high CO2 adsorption efficiency throughout the solution's service life
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 air purifier effectively maintains higher oxygen levels and reduces CO2 concentrations, improving human metabolism by maximizing CO2 adsorption and ensuring better air quality in closed environments.
Implementation Method 1
a CO2 adsorption unit into which the air sucked into the body is taken by means of an air duct and a pump and which is suitable for being supplied or filled with basic liquid solution
Implementation Method 2
the carbon dioxide in the air reacts with the basic liquid solution in the CO2 adsorption unit so as to adsorb the carbon dioxide and convert the same to carbonate
Implementation Method 3
The air passing through the cylindrical body passes through the opening on the diffuser so as to mix with the basic liquid solution in the CO2 adsorption unit so as to create bubbles
Implementation Method 4
The air exiting through the opening on the cylindrical body passes through the plurality of holes on the membrane and mixes with the basic liquid solution in the CO2 adsorption unit due to pressure difference
