Solution Overview

Problem

Aircraft passenger cabins, especially in economy-class, lack flexible space for cabin crew to perform tasks and for passenger entertainment/socialization due to limited free space, and existing solutions do not effectively utilize underutilized areas near exit doors without compromising safety or existing storage/seating.

Innovation Solution

A transformable monument system that can be deployed near exit doors, utilizing underutilized space to create multi-mode areas for cabin crew work, passenger self-service, and entertainment, while also protecting the cabin doors from unauthorized access by extending or pivoting sections to obstruct the exit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional purpose-built monuments are used in aircraft cabins, then cabin crew have dedicated work/storage spaces for catering, but free space is extremely limited and no additional workspace or passenger amenities can be provided

Engineering Contradiction:
Improveworkspace provisionVSAvoidfree space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The monument incorporates transformable components including foldable tables, extendable surfaces, and movable partitions that can dynamically reconfigure the limited space to provide workspace for cabin crew and entertainment areas for passengers as needed, while maintaining compact storage when not in use

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The monument is designed to serve multiple functions: providing workspace for cabin crew, creating entertainment/socialization spaces for passengers, and maintaining storage capabilities, all within the same structure to maximize utilization of limited free space

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

2Productivity

If free space near exit doors is left unutilized to facilitate safe evacuation, then emergency evacuation is ensured, but the space is underutilized during normal cruising conditions

Engineering Contradiction:
Improvespace utilizationVSAvoidevacuation safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The monument includes deployable obstruction elements such as foldable panels and extendable barriers that can be rapidly deployed to block exit doors during normal operations, creating usable space, and quickly retracted or folded away during emergencies to ensure unobstructed evacuation paths

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The monument is pre-configured with rapid-deployment mechanisms that allow the obstruction elements to be quickly deployed or retracted as needed, enabling the space to be utilized during normal cruising while ensuring immediate availability for emergency evacuation when required

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If transformable sections are added to create multi-mode areas, then additional workspace and entertainment spaces are provided, but device complexity increases

Engineering Contradiction:
Improvemulti-mode functionalityVSAvoidtransformable mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The monument is divided into modular transformable sections including foldable tables, extendable surfaces, and movable partitions that can be independently operated to create different configurations for workspace, entertainment, or storage, reducing overall system complexity through modular design

Inventive Principle:
Principle #1Segmentation

AI summary

Transformable monuments may be positioned proximate to aircraft exit doors to utilize the doorway spaces as temporary workspaces for cabin crew or destination spaces for passengers once cruising altitude is achieved. A transformable monument includes transforming portions that extend or pivot into an aircraft cross-aisle upon actuation of an exterior latch by either hand. The transforming portions extend or pivot into horizontal surfaces for crew or passenger use while protecting the exit doors from unauthorized access by passengers inflight. Transforming portions of a single monument may extend partially or fully across the cross-aisle, or a system of two transformable monuments on either side of the exit door may collectively define the temporary space. The upper and middle sections of the monument may include additional storage or self-service compartments for providing refreshments or other amenities to passengers.
