Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processes for cleaning and decontaminating aircraft surfaces are insufficient to kill bacteria and viruses present on touch points, leading to potential microbial transmission among passengers.
Innovation Solution
Integration of antimicrobial materials, such as copper, silver, or photocatalytic materials like titanium dioxide and zinc oxide, into or onto aircraft components, which can deactivate microbes upon contact, with optional fire-resistant properties and methods like atomic layer deposition or coating applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing cleaning and decontaminating processes are used, then the aircraft surfaces can be wiped down, but they are insufficient to kill bacteria and viruses present on touch points
Solution Approach 1:
The patent changes the chemical parameters of the surface materials by incorporating antimicrobial substances (copper, silver, zinc oxide, titanium dioxide) into the material composition. This transforms ordinary surfaces into antimicrobial surfaces that can deactivate microbes through contact, thereby improving microbial deactivation effectiveness without requiring complex additional systems
Solution Approach 2:
The patent uses composite materials by combining base materials (polymers, metals) with antimicrobial additives (copper particles, silver ions, zinc oxide, titanium dioxide). These composite materials provide both the structural function of the original material and the antimicrobial function of the added substances, resolving the contradiction between effectiveness and implementation complexity
2Reliability
If antimicrobial materials are integrated into aircraft components, then microbial transmission is reduced, but fire resistance requirements must be maintained
Solution Approach 1:
The patent applies local quality by concentrating antimicrobial materials specifically at touch points and high-contact areas rather than throughout the entire component. This localized application maintains fire resistance in the bulk material while providing microbial deactivation effectiveness at the critical surfaces where passengers contact the components
Solution Approach 2:
The patent modifies the surface parameters of the material by adding thin layers or coatings of antimicrobial substances (such as copper, silver, or photocatalytic materials) without changing the fundamental fire-resistant properties of the base material. This allows the component to maintain its fire resistance while gaining microbial deactivation capability at the surface level
3Reliability
If photocatalytic materials are used, then antimicrobial activity is enhanced, but additional materials and processes are required
Solution Approach 1:
The patent merges multiple functions into a single material system by combining photocatalytic materials (titanium dioxide, zinc oxide) with antimicrobial properties. This integration allows the same material to provide both photocatalytic self-cleaning capabilities and direct antimicrobial activity, thereby enhancing antimicrobial effectiveness without proportionally increasing device complexity
Solution Approach 2:
The patent employs universal materials such as titanium dioxide and zinc oxide that serve multiple functions: they provide photocatalytic activity for breaking down organic contaminants, exhibit direct antimicrobial properties, and maintain fire resistance. This multi-functionality enhances antimicrobial activity while avoiding the need for separate systems for each function, thus managing complexity
