Aircraft Rear-Space Storage Unit with Movable Partition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft rear-space layouts for long-haul flights often lack flexibility to adjust between passenger comfort and flight personnel workspaces, as existing designs typically occupy the entire available surface behind the last door with fixed galley and trolley storage, failing to accommodate varying flight phases and service requirements effectively.
Innovation Solution
An adjustable storage unit with a movable partition and shelves that can be reconfigured to separate the galley from passenger space, allowing increased space utilization by translating the partition and shelves to adapt to different service needs, providing both a work area for personnel and a convivial space for passengers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed galley and trolley storage layout is provided in the aircraft rear space, then the work space for meal preparation is ensured, but the flexibility to adjust for different flight phases and service requirements is reduced
Solution Approach 1:
The patent applies the dynamics principle by making the partition wall movable rather than fixed. The partition can be translated along the longitudinal axis of the aircraft to adjust the separation between the galley workspace and passenger space, allowing the layout to adapt to different flight phases and service requirements while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent segments the rear space into distinct functional zones (galley workspace and passenger space) separated by a movable partition. This segmentation allows each zone to be independently adjusted and optimized for different operational requirements without redesigning the entire layout.
2Area of stationary object
If the housing occupies the entire available surface behind the last door, then maximum storage capacity for trolleys is achieved, but the available space for passenger comfort and work area is reduced
Solution Approach 1:
The movable partition allows the boundary between the housing and passenger space to be dynamically adjusted. When passenger space needs to be maximized, the partition can be moved to minimize the housing footprint; when trolley storage capacity is prioritized, the partition can be repositioned to maximize the housing space.
Solution Approach 2:
The patent changes the positional parameter of the partition wall to optimize the balance between passenger space and storage capacity. By varying the partition's position along the longitudinal axis, the system can adapt the spatial allocation to match different operational priorities.
3Adaptability or versatility
If a movable partition is introduced to separate galley and passenger space, then space flexibility and adaptability are improved, but the device complexity increases
Solution Approach 1:
The partition is designed as a movable component that can be translated along a defined path, introducing dynamics to an otherwise static interior layout. This simple dynamic element provides significant adaptability without requiring complex mechanical systems.
Solution Approach 2:
The movable partition acts as an intermediary element that mediates between the galley workspace and passenger space. It provides a simple, straightforward mechanism for spatial separation and adjustment without introducing complex control systems or multiple moving components.

AI summary
A storage unit for aircraft trolleys includes a housing accommodating at least one aircraft trolley and including a horizontal tray arranged on top of the housing. The storage unit includes a movable partition extending in a plane perpendicular to the tray and above the tray so that at least a part of the movable partition extends up to a ceiling of an aircraft. The partition is movable in translation from one edge of the tray to an opposite edge.
