Aircraft Air Management With Negative Ions for Cabin Pathogen Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air management systems in aircraft are inadequate in handling toxic chemicals, gases, and harmful viruses/bacteria, as they fail to effectively filter out contaminants, leading to acute symptoms and potential outbreaks due to the persistence of harmful pathogens like SARS-CoV-2 in cabin air.
Innovation Solution
The integration of a negative ion generator that produces negative ions or hydroxyl radicals, which mix with cabin air to inhibit bacterial and viral growth, reduce toxic gas concentrations, and neutralize pollutants, using a mixer unit to distribute these ions throughout the aircraft cabin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional air management systems with HEPA filters are used, then basic particle filtration is achieved, but toxic chemicals, gases, and harmful viruses/bacteria cannot be effectively handled
Solution Approach 1:
The patent changes the chemical parameter of the air by introducing negative ions that chemically react with and neutralize toxic chemicals, gases, and pathogens. This transforms the air composition from merely filtered to chemically treated, resolving the contradiction between basic filtration and effective pathogen neutralization.
Solution Approach 2:
The negative ion generator acts as an intermediary substance that mediates between the filtered air and the harmful contaminants. The negative ions serve as a reactive intermediary that binds to and neutralizes toxic chemicals, gases, and pathogens, enabling effective handling without direct contact between the filter and these contaminants.
2Object-affected harmful factors
If HEPA filters are used to filter cabin air, then particulate matter is reduced, but a significant percentage of viruses pass through the filters
Solution Approach 1:
The patent replaces the purely mechanical HEPA filtration system with a chemical treatment approach using negative ions. Instead of relying solely on physical barrier mechanics, the system uses chemical reactions between negative ions and viral particles to neutralize them, thereby improving virus blocking capability while maintaining particulate matter filtration.
Solution Approach 2:
The air treatment system becomes a composite approach combining physical filtration (HEPA) with chemical treatment (negative ion generation). This composite system leverages both the particle-capturing ability of HEPA filters and the pathogen-neutralizing capability of negative ions, resolving the contradiction between particulate filtration and virus blocking.
3Object-affected harmful factors
If negative ion generator is integrated into the air management system, then pathogen neutralization and toxic gas reduction are achieved, but device complexity increases
Solution Approach 1:
The negative ion generator is designed to perform multiple functions simultaneously: neutralizing pathogens, reducing toxic gases, and treating contaminants. This multi-functionality reduces the need for separate treatment systems, thereby mitigating the increase in device complexity while achieving comprehensive contaminant neutralization.
Solution Approach 2:
The patent merges the negative ion generation function with the existing air management system architecture. By integrating the ion generator into the fluid communication pathway already present in the system, the design combines multiple treatment functions without requiring entirely separate systems, thus limiting the increase in overall device complexity.

Function Achieved in This Case
This solution significantly improves air quality by neutralizing airborne pathogens, reducing toxic gas concentrations, and preventing the outbreak of harmful viruses, thereby enhancing passenger and crew safety by ensuring cleaner air within the aircraft.
Implementation Method 1
the negative ion generator is configured to generate negative ions that mix with the filtered air from the aircraft cabin in the mixer unit
Implementation Method 2
after joint union or absorption of the generated negative ions with positive ions from the mixed air, the joint union or absorption of the generated negative ions with the positive ions inhibits growth of bacterial or virus activity
Implementation Method 3
the negative hydroxyl radicals or ions react by transforming hydrogen from components in the mixed air into water
