Aircraft Cabin Privacy Screen With Rail-Mounted Modular Partition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passenger cabin partition systems are inflexible, heavy, and require significant storage space, limiting their ability to create variable and efficient delimitation of zones in aircraft cabins for different travel classes and emergency situations.
Innovation Solution
A modular cabin element with a positionally variable privacy screen roller blind that can be attached to guide rails using quick-release fasteners, allowing for adjustable and flexible partitioning, extending between the cabin element and the ceiling, and capable of being locked at intermediate positions, reducing weight and storage requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional curtain systems or fixed partitions are used to delimit zones in passenger cabins, then zone delimitation is achieved, but the system becomes heavy, inflexible in positioning, and requires considerable stowage space
Solution Approach 1:
The patent replaces traditional rigid partitions and heavy curtain systems with a flexible roller blind that can be easily positioned and stored. The roller blind uses a thin film or flexible material that rolls up into a compact mechanism, providing zone delimitation without the weight and stowage space requirements of conventional systems while maintaining positioning flexibility through the roller mechanism.
Solution Approach 2:
The patent implements a dynamic positioning system where the roller blind can be easily moved to different positions along the cabin using a roller mechanism. This allows the partition to adapt to different zone requirements dynamically, unlike fixed partitions, while the rolling mechanism keeps the system lightweight and compact when not in use.
2Adaptability or versatility
If traditional curtain systems or fixed partitions are used to delimit zones in passenger cabins, then zone delimitation is achieved, but the system requires considerable stowage space when not in use
Solution Approach 1:
The roller blind mechanism nests the blind material within a compact roller housing when not in use. The flexible partition material rolls up and stores within the cylindrical roller mechanism, reducing stowage space from the volume of an extended partition or curtain to a compact cylindrical form that can be easily accommodated in the cabin structure.
Solution Approach 2:
The use of flexible thin film material allows the partition to be compacted into a minimal stowage volume while maintaining its functionality when deployed. The thin film nature of the roller blind enables it to roll up tightly without losing its delimitation capability, significantly reducing the space required compared to rigid partitions or bulky curtain systems.
3Strength
If honeycomb design partitions with aluminum edge protection are used, then rigidity is improved, but weight increases and positioning flexibility is reduced
Solution Approach 1:
The patent replaces static rigid partitions with a dynamic roller blind system that can be positioned flexibly at any location along the cabin. The roller mechanism allows easy adjustment and repositioning, providing adaptability that fixed rigid partitions cannot achieve, while the flexible blind material provides sufficient structural integrity for its delimitation function.
Solution Approach 2:
The patent uses flexible blind material in the roller mechanism that provides sufficient rigidity for zone delimitation while maintaining flexibility for easy positioning. The rolled-up flexible material maintains its shape and provides adequate structural support for privacy screening without requiring heavy rigid construction like honeycomb partitions.
4Reliability
If space cell systems extending between floor and ceiling are used for partitioning, then zone delimitation is achieved, but installation speed is reduced due to size and weight
Solution Approach 1:
The patent segments the partition function into a compact roller mechanism that can be quickly installed and positioned. Instead of installing large rigid space cell structures, the roller blind system can be divided into modular units that are easier and faster to install, while still providing effective zone delimitation when deployed.
Solution Approach 2:
The flexible roller blind material provides effective zone delimitation through its ability to create a continuous barrier when extended, matching the effectiveness of rigid space cell systems. The flexibility of the material allows it to conform to the cabin structure and provide reliable privacy screening without the installation complexity and time requirements of rigid framed systems.

AI summary
The invention relates to a device for creating an individually delimited zone of a passenger cabin in a means of transport for at least one passenger seat. The device comprises a modular cabin element that has been attached in a positionally variable manner to stationary guide rails of the passenger seat by way of quick-release fasteners. Associated with this cabin element is an extendable and affixable privacy screen roller blind that forms a flexible dividing element, which privacy screen roller blind extends from the underside of the hatrack or the PSU panel or the ceiling arrangement, and in the lateral region in addition the sidewall lining of the passenger cabin, to the modular cabin element, and by means of which privacy screen roller blind an individually delimited zone can be implemented.
