Solution Overview

Problem

Current methods for identifying and detecting emerging pathogens in aircraft cabins are inadequate, relying on individual diagnostic tests with uncertain results, which hinders international travel and poses risks due to asymptomatic or pre-symptomatic carriers.

Innovation Solution

A method and system for collecting and analyzing air samples from aircraft using a collector to capture particulates, conduct tests, and relay results to a central data center for identifying non-described pathogens, including phylogenetic analysis and sequence comparison, with a database for storing and communicating results to health authorities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If individual diagnostic tests are used to detect pathogens, then the testing process is simple, but the reliability of detection is insufficient due to uncertain results

Engineering Contradiction:
Improvedetection reliabilityVSAvoidtesting system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple diagnostic testing approaches (PCR, next-generation sequencing, and traditional culture methods) into a unified monitoring system. This integration allows the system to leverage the high sensitivity of PCR, the comprehensive pathogen identification capability of NGS, and the functional validation of culture methods, thereby significantly improving detection reliability while managing system complexity through automated workflow coordination.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The monitoring system is designed with multi-functionality to perform various detection methods (molecular testing, sequencing, cultural methods) and data analysis functions within a single platform. This universal system can adapt to different pathogen types and detection requirements, providing reliable results across diverse scenarios while maintaining a standardized operational framework.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If comprehensive pathogen monitoring is implemented, then emerging pathogens can be identified, but the cost and complexity of the system increase

Engineering Contradiction:
Improvepathogen detection capabilityVSAvoidmonitoring system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The monitoring system is segmented into distinct functional modules: sample collection units, DNA extraction modules, PCR amplification stations, NGS sequencing platforms, and data analysis workstations. Each module performs a specific function and can be independently optimized or maintained. This segmentation enables comprehensive pathogen monitoring capability while managing overall system complexity through modular architecture and standardized interfaces.

Inventive Principle:
Principle #1Segmentation

3Loss of time

If rapid pathogen detection is implemented to facilitate travel, then travel disruption is reduced, but the risk of false positives or negatives increases

Engineering Contradiction:
Improvetravel disruption timeVSAvoiddetection accuracy
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The system performs preliminary pathogen detection and risk assessment before passengers board aircraft. By conducting comprehensive screening of passengers, crew, and aircraft environments in advance, the system identifies potential pathogens early, enabling preventive measures to be taken before travel begins. This preliminary action reduces the need for disruptive mid-travel testing while maintaining high detection accuracy through the use of multiple validated diagnostic methods.

AI summary

A method for collecting and testing particulates from aircraft air is disclosed. The method includes capturing particulates in at least one of an outlet flow path or a recirculation flow path with a collector over a period of time, removing the collector from at least one of the outlet flow path or the recirculation flow path for testing, concentrating the collected sample, conducting a test on at least one particulate captured in the collector, relaying a result of the test to a central data center to store the results, and identifying a previously non-described emerging pathogens within the results.
