Solution Overview

Problem

Existing air travel systems lack effective methods for precise pathogen detection and environmental microbial control in aircraft cabins, relying on individual diagnostic tests with uncertain results, which hinder travel and route maintenance.

Innovation Solution

A system using a conical collector with a reagent fluid and HEPA filter to collect and purify air samples, conducting PCR tests like epPCR, qPCR, or RT-qPCR to analyze genetic material from ambient cabin air, with vessels placed strategically throughout the aircraft for comprehensive sampling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If individual diagnostic tests are used for pathogen detection, then testing can be performed on passengers, but the results are uncertain and reduce people's inclination to travel

Engineering Contradiction:
Improvepathogen detection precisionVSAvoidtest result reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The system divides the aircraft into multiple sampling zones with several vessels positioned at different locations (between seats, in galleys, lavatories, corridors, cargo bays) to collect representative air samples from various cabin areas, improving detection precision through spatial segmentation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system extracts and concentrates genetic material (DNA/RNA) from large volumes of cabin air through a reagent fluid in a conical collector, then isolates the concentrated sample for PCR testing, enabling reliable pathogen detection from environmental air samples

Inventive Principle:
Principle #2Taking out (Extraction)

2Object-affected harmful factors

If borders are shutdown and international travel is reduced to ensure safety, then pathogen transmission risk is reduced, but the global economy and air travel industry are severely impacted

Engineering Contradiction:
Improvevirus transmission riskVSAvoidair travel productivity
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The system provides real-time feedback on aircraft air quality through PCR testing of collected samples, enabling data-driven decisions about flight safety and continued operation, allowing travel to resume when safety criteria are met

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The aircraft performs self-monitoring of its own air quality through the autonomous sampling and testing system, eliminating the need for external border controls and shutdowns by providing proof of internal safety

Inventive Principle:
Principle #25Self-service

3Reliability

If aircraft are assumed contaminated until proven clean, then safety is prioritized, but travel uncertainty increases and routes are maintained less

Engineering Contradiction:
Improveaircraft cleanliness assuranceVSAvoidtravel uncertainty
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system performs preliminary sampling and testing of aircraft air before flights or at scheduled intervals, providing advance confirmation of cleanliness status and reducing uncertainty for travelers and operators

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system replaces subjective assumptions about contamination with objective scientific evidence from PCR testing, substituting mechanical doubt with measurable data about air quality

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
