Aircraft Cabin Lavatory Partition for Enlarged Mobility Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft lavatories are too small for passengers with reduced mobility, and existing solutions do not adequately utilize available space for enlargement.
Innovation Solution
A bi-functional partition wall in the lavatory arrangement that moves between primary and secondary positions, allowing two lavatories to combine into an enlarged space by extending into the aisle area, providing additional space for passengers with reduced mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If lavatories are made small to maximize passenger seating space, then space economy is improved, but lavatory space for passengers with reduced mobility deteriorates
Solution Approach 1:
The partition wall is made movable between a first position (separating lavatories) and a second position (combined lavatory mode), allowing the lavatory configuration to dynamically adapt between standard service mode and PRM assistance mode, thus resolving the contradiction between space economy and accessibility
Solution Approach 2:
The lavatory arrangement is divided into multiple compartments separated by movable partition walls, which can be independently repositioned to create different spatial configurations, enabling both small individual lavatories and large combined lavatories as needed
2Area of stationary object
If partition wall is removed to create enlarged lavatory, then lavatory space for PRM is improved, but device complexity increases
Solution Approach 1:
The movable partition wall serves multiple functions: it acts as a separator during normal operation, provides structural support for the lavatory compartments, and can be repositioned to create enlarged access spaces, thereby reducing the need for additional dedicated structures and minimizing overall system complexity

AI summary
A lavatory arrangement for an aircraft cabin includes a first lavatory compartment accessible from an aisle area via a first door, and a second lavatory compartment accessible from the aisle area via a second door. A movable bi-functional partition wall is arranged between the first and second lavatory compartments. The bi-functional partition wall is movable between primary and secondary positions. In the primary position, the bi-functional partition wall separates the first lavatory compartment from the second lavatory compartment, and in the secondary position, the bi-functional partition wall is brought into a position outside the first and second lavatory compartments, in which secondary position the first lavatory compartment and the second lavatory compartment provide an enlarged common lavatory. In the secondary position, the bi-functional partition wall is arranged at least partly outside the lavatory arrangement and within the aisle area outside the first lavatory compartment and the second lavatory compartment.
