Solution Overview

Problem

Existing air mobility apparatuses face challenges in restricting the movement of baggage to the passenger cabin, ensuring ease of loading and unloading, and maintaining passenger comfort during boarding and alighting.

Innovation Solution

The air mobility apparatus features a fuselage with a first cabin for passengers and a second cabin for baggage, equipped with a rear door comprising an inner door and an outer door that can be independently opened and closed, allowing for efficient loading and unloading of baggage while preventing it from entering the passenger cabin.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single door is used at the side of the fuselage for both passenger boarding and baggage loading, then the structure is simple, but baggage cannot be restricted to the baggage cabin and may move to the passenger area during flight

Engineering Contradiction:
Improvebaggage containmentVSAvoiddoor structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The door structure is divided into two independent parts: an inner door that separates the passenger cabin from the baggage cabin, and an outer door that separates the baggage cabin from the external environment. These doors can be opened and closed independently, allowing the inner door to remain closed during flight to contain baggage while the outer door can be opened for baggage loading/unloading without compromising passenger safety.

Inventive Principle:
Principle #1Segmentation

2Reliability

If large-volume or large-weight baggage is placed in a separate space from the passenger seating area, then passenger safety is improved, but passengers experience discomfort when carrying baggage to the rear of the passenger area in a narrow space

Engineering Contradiction:
Improvepassenger safetyVSAvoidbaggage transport convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The baggage cabin serves as an intermediary space between the passenger cabin and the external environment. Passengers can transfer baggage to the baggage cabin through the outer door without carrying it through the narrow passenger cabin space. The inner door remains closed to maintain separation, but the outer door can be opened to allow direct access to the baggage cabin from outside the aircraft, eliminating the need for passengers to navigate narrow internal passages with heavy or large baggage.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the inner door and outer door are configured to be independently opened and closed, then baggage can be loaded and unloaded while maintaining passenger containment, but the door mechanism becomes more complex

Engineering Contradiction:
Improvebaggage loading efficiencyVSAvoiddoor mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The door system is segmented into two independently operable units (inner door and outer door), each with its own opening mechanism. This allows the outer door to be opened for baggage loading/unloading while the inner door remains closed to maintain passenger containment. The independence of the two door operations enables continuous productivity - baggage can be accessed without compromising passenger safety, and vice versa.

Inventive Principle:
Principle #1Segmentation
