Movable Cargo Barrier With Closeout Membrane for Aircraft Isolation Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cargo compartments in aircraft, particularly freighter aircraft, lack environmental segregation, exposing sensitive cargo to drastic temperature and humidity changes when the cargo door is opened.
Innovation Solution
A barrier system with a base, divider wall, and closeout membrane that can be moved within the cargo compartment to create isolation zones, using rollers for mobility and vents for controlled airflow, with optional inflatable features and user interface for environmental control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cargo compartment is kept open for easy loading and unloading, then productivity is improved, but temperature and humidity stability deteriorate
Solution Approach 1:
The cargo compartment is divided into multiple isolated zones using movable divider walls and closeout membranes. This segmentation allows different environmental conditions to be maintained in different zones simultaneously, enabling the cargo door to remain open for loading/unloading while sensitive cargo in other zones maintains stable temperature and humidity.
Solution Approach 2:
The barrier system incorporates movable divider walls and adjustable closeout membranes that can be dynamically reconfigured based on loading requirements. The system transitions between open and closed states, providing environmental protection only when and where needed, thus maintaining productivity while preventing harmful temperature fluctuations.
2Temperature
If the cargo compartment is segmented into isolation zones, then environmental control is improved, but device complexity increases
Solution Approach 1:
The closeout membrane is a flexible, thin film structure that sealingly engages with the cargo compartment walls and divider walls. This flexible membrane provides effective environmental separation without requiring complex rigid structures, joints, or fastening mechanisms, thus maintaining relative simplicity while achieving superior environmental control.
Solution Approach 2:
The barrier system uses movable and adjustable components that can be reconfigured as needed. The divider walls can be repositioned and the closeout membrane adjusted to create isolation zones only when required, avoiding the need for permanent complex structures throughout the entire cargo compartment.
3Strength
If the divider wall is made rigid for structural stability, then strength is improved, but adaptability deteriorates
Solution Approach 1:
The divider wall system combines rigid structural elements with movable mounting mechanisms. The rigid divider walls provide necessary strength and environmental separation, while their ability to be repositioned along the cargo compartment length provides adaptability. The closeout membrane further enhances flexibility by adjusting to different configurations.
Solution Approach 2:
The barrier system is divided into modular components including separate divider walls and closeout membranes. This segmentation allows each component to be optimized independently - divider walls can be rigid for strength while the overall system remains adaptable through the modular arrangement and movable mounting positions.
