Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air filtration systems in aircraft, such as HEPA filters, are not effective in continuously maintaining air quality within enclosed spaces and do not adequately remove odors, while also being costly in terms of filter replacement and energy consumption.
Innovation Solution
An aircraft galley with an integrated air ionizer system, which includes an ion emitter coupled to an air outlet and a control unit to manage the ion output, is designed to improve air quality by neutralizing pathogens and odors through ionization of the air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HEPA filters are used to filter air during recirculation, then air filtration effectiveness is improved, but energy consumption and cost increase
Solution Approach 1:
The invention divides the air treatment function into two segments: HEPA filters handle particle filtration at central locations, while ion emitters handle pathogen neutralization and odor removal at distributed galley locations. This segmentation allows each component to operate more efficiently at its optimal point, reducing overall energy consumption while maintaining comprehensive air quality.
Solution Approach 2:
The ion emitter acts as an intermediary that enhances the effectiveness of air recirculation by neutralizing pathogens and odors that pass through HEPA filters. The ion emitter uses electrostatic fields to create ions that attach to airborne contaminants, making them easier to remove and reducing the burden on central filtration systems.
2Reliability
If HEPA filters are used to filter air during recirculation, then air filtration effectiveness is improved, but filter replacement cost increases
Solution Approach 1:
The air treatment system is segmented into HEPA filtration for particles and ion emission for biological contaminants. This division allows the ion emitter to handle pathogen neutralization, reducing the load on HEPA filters and extending their service life, thereby reducing replacement frequency and costs.
Solution Approach 2:
The invention replaces the mechanical filtration approach with an electrostatic field-based ion emission system for pathogen neutralization. This substitution reduces reliance on consumable HEPA filters, as ion emitters can operate for extended periods without replacement, lowering ongoing maintenance costs.
3Reliability
If air filters are used to filter air during recirculation, then air filtration is provided, but odor removal effectiveness is insufficient
Solution Approach 1:
The ion emitter serves as an intermediary that specifically targets odor molecules and volatile organic compounds that pass through HEPA filters. The emitted ions attach to these molecules, neutralizing their odorous properties and making them easier to remove from the air stream, thereby complementing the mechanical filtration system.
Solution Approach 2:
The invention changes the physical-chemical parameters of airborne odors by introducing ions that alter the molecular structure and charge state of odor-causing molecules. This transformation converts difficult-to-remove odorous compounds into more easily managed forms, enhancing overall odor removal effectiveness.
