Flexible Curtain Cabin Zone Separator for Overhead Bins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passenger cabin interior designs for aircraft lack flexibility in subdividing zones, as fixed partitions are inflexible and movable partitions are not always effective in maximizing space utilization based on varying passenger demands.
Innovation Solution
A separating device using a flexible curtain element attached to a movable overhead luggage bin shell, with a fixing and tensioning system that ensures secure and adjustable separation between zones, allowing for easy reconfiguration of cabin layouts based on passenger class distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed partitions are used to separate passenger cabin zones, then separation reliability is improved, but adaptability deteriorates
Solution Approach 1:
The partition system transitions from fixed to movable by utilizing the overhead bin's movable shell as a carrier for the curtain element. The curtain can be positioned at different locations along the bin's length and secured at various heights, enabling dynamic reconfiguration of cabin zones while maintaining reliable separation when deployed.
Solution Approach 2:
The overhead bin serves multiple functions: it provides luggage storage and simultaneously acts as a structural carrier for the partition system. The movable shell of the bin becomes a dual-purpose component, both protecting luggage and supporting the curtain mechanism for zone separation.
2Adaptability or versatility
If movable partitions are used to separate passenger cabin zones, then adaptability is improved, but separation reliability deteriorates
Solution Approach 1:
The curtain element acts as an intermediary between the movable bin shell and the zone separation function. This fabric-based mediator provides reliable visual and acoustic separation while allowing for easy deployment and repositioning, bridging the gap between structural reliability and operational flexibility.
Solution Approach 2:
The partition system utilizes a flexible curtain element instead of rigid movable partitions. This thin film approach maintains separation effectiveness while enabling easy movement and reconfiguration, solving the reliability-adaptability contradiction through material selection.
3Ease of operation
If curtains are fixed below PSU panels to separate zones, then ease of operation is improved, but adaptability deteriorates
Solution Approach 1:
The partition system transitions from a fixed location below the PSU panel to a dynamic positioning system utilizing the entire length of the overhead bin. The curtain can be secured at any position along the bin's longitudinal axis, enabling flexible zone separation while maintaining easy deployment through the same simple attachment mechanism.

AI summary
A separating device (10) for separating two zones of a passenger cabin equipped with overhead luggage bins (102) comprising a movable shell (108) comprises a curtain element (12) which is made of a flexible material and which is dimensioned and shaped so as to be capable of at least partially covering an area extending below an overhead luggage bin (102) with its movable shell (108) being in its closed position in a direction substantially perpendicular to a longitudinal axis of the overhead luggage bin (102). The curtain element (12) has a first edge adapted to face the movable shell (108) of the overhead luggage bin (102) when the separating device (10) is mounted in the passenger cabin. The separating device (10) further comprises a holder (14) supporting a first end of the first edge of the curtain element (12) and a fixing device (24) adapted to fix a second end of the first edge of the curtain element (12) to the movable shell (108) of the overhead luggage bin (102).
