Inflatable Air Chamber Wall Structure for Lightweight Aircraft Berths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft berth installations, such as honeycomb structures, are complex and difficult to install, requiring significant effort and time, and are not lightweight, which hinders quick and economical outfitting of aircraft interiors.
Innovation Solution
A construction using flexible flat material enclosed air chambers with internal crosspieces that inflate to form a stable, sound-absorbing wall structure, allowing for easy installation and use as partitions or berths, which can be quickly set up and moved within the aircraft, and are lighter than conventional honeycomb structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If honeycomb structures are used to separate individual berths, then stable partition walls are formed, but the installation becomes complex and time-consuming
Solution Approach 1:
The partition wall is divided into multiple separate air chambers that can be independently installed and then connected. Each air chamber is a separate module that can be moved through aircraft doors and assembled in place, transforming a complex monolithic structure into simple modular components.
Solution Approach 2:
Air chambers are inflated with compressed air to create rigid partition walls. The pneumatic pressure provides the structural stability normally requiring solid honeycomb materials, while allowing the walls to be collapsed for easy transport and installation through aircraft doors.
2Stability of the object's composition
If honeycomb structures are used for berth separation, then stable walls are created, but the weight increases
Solution Approach 1:
Thin flexible membranes form the walls of air chambers, replacing heavy solid honeycomb materials. When inflated, these thin films create rigid structures that provide the necessary stability while minimizing weight, crucial for aircraft applications.
Solution Approach 2:
Internal pneumatic pressure creates the structural rigidity needed for stable partition walls without requiring heavy solid materials. The pressurized air acts as a lightweight structural element that provides strength and stability only when needed.
3Stability of the object's composition
If conventional structures are used for aircraft interior outfitting, then stable partitions are achieved, but the installation time increases
Solution Approach 1:
The partition system is segmented into multiple portable air chamber modules that can be independently transported and quickly assembled. This modular approach allows parallel installation of multiple sections, dramatically increasing installation speed compared to monolithic structures.
Solution Approach 2:
The air chambers transition from a collapsed state during transport to an inflated rigid state during installation. This dynamic transformation allows the structure to be compact for rapid transport through aircraft doors and then quickly deployed to form stable partitions.
4Stability of the object's composition
If rigid structures are used for aircraft berths, then stable compartments are formed, but the adaptability decreases
Solution Approach 1:
The air chamber partitions can be dynamically inflated or deflated to adapt to different space requirements. When inflated, they provide stable rigid compartments; when deflated, they can be repositioned or removed to reconfigure the space, offering both stability and adaptability.
Solution Approach 2:
The same air chamber modules can be used for multiple purposes: as partition walls, as berth enclosures, or as temporary room dividers. Their ability to be inflated and deflated allows a single component to serve multiple functions throughout the aircraft's operational life.

AI summary
The invention comprises a structure having at least two separate air chambers (7) enclosed by flexible, flat material (8) and having flexible bars (9) in the interior thereof for stabilizing an external shape of the air chambers (7). The structure is characterized in that the air chambers (7) form a wall structure (4) in the inflated state. By means of such a wall structure (4)—preferably in conjunction with a corresponding ceiling structure (16)—lightweight berths (1), particularly for aircraft crew, flight passengers, or transported injured persons, can be set up quickly and simply.
