Problem

In aircraft without an inflight crew, it is challenging to provide prompt services when passengers experience tension or emergencies during autonomous flight.

Innovation Solution

An apparatus and method that utilize biometric data and image analysis through machine learning models to determine passenger states, enabling rapid adjustment of flight paths, provision of first aid, and relief measures based on passenger conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If autonomous flight is implemented without inflight crew, then operational efficiency and productivity are improved, but the ability to provide prompt service during passenger emergencies deteriorates

Engineering Contradiction:
Improveoperational efficiencyVSAvoidservice provision capability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system enables the aircraft to autonomously monitor passenger conditions through biometric sensors and image analysis, automatically detect emergencies, and execute appropriate responses without crew intervention. The aircraft serves itself by integrating detection, decision-making, and action-execution capabilities into the autonomous flight system.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

A service providing apparatus acts as an intermediary between passengers and the autonomous flight system. This apparatus includes biometric sensors, image analysis cameras, and a control module that processes passenger data and coordinates emergency responses, bridging the gap between autonomous operation and passenger care.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If comprehensive biometric monitoring and image analysis systems are deployed, then passenger state detection precision is improved, but device complexity increases

Engineering Contradiction:
Improvepassenger state detection precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The service providing apparatus performs multiple functions using integrated systems: biometric data collection, image capture, machine learning analysis, emergency detection, and response coordination. A single multi-functional module replaces what would otherwise require separate specialized systems for each function.

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

Solution Approach 2:

The system combines biometric sensors, image analysis cameras, machine learning models, and control modules into an integrated service providing apparatus. Multiple detection and response functions are merged into a unified system that operates autonomously, reducing overall system complexity through consolidation.

Inventive Principle:
Principle #5Merging (Combining)
