Aircraft Lavatory Wall Stowage Layout for Space-Constrained Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft lavatories have limited space for storage due to their compact design, with unused space often going unutilized outside the walls, which can hinder efficiency, comfort, and maintenance.
Innovation Solution
A stowage compartment is created between newly installed walls in the lavatory, extending from the ceiling to above a low-profile sink, providing access through a pull-out drawer or door, which increases storage without reducing passenger legroom or galley space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the lavatory is designed with a compact footprint to minimize space occupation, then passenger legroom and galley space are preserved, but storage space within the lavatory becomes severely limited
Solution Approach 1:
The patent applies dimensionality change by utilizing the wall thickness dimension to create storage compartments. Instead of expanding the lavatory footprint in the horizontal plane, the invention creates storage spaces within the wall structure itself, effectively using the third dimension (depth/thickness) to provide storage capacity without affecting passenger legroom or galley space.
Solution Approach 2:
The patent implements nesting by placing storage compartments within the wall structure of the lavatory. The storage spaces are nested inside the wall thickness, allowing the lavatory to maintain its compact external dimensions while providing internal storage capacity for amenities and supplies.
2Ease of operation
If unused space outside the lavatory walls is utilized for other purposes, then passenger comfort and seat recline are maintained, but available storage space in the aircraft is reduced
Solution Approach 1:
The patent applies multi-functionality by designing the wall structure to serve multiple purposes: it provides structural support for the lavatory, defines the lavatory boundary, and simultaneously contains storage compartments. This allows the same physical space (wall thickness) to fulfill both structural and storage functions, eliminating the need to sacrifice seat recline space for storage.
Solution Approach 2:
The invention uses the wall thickness dimension to create storage spaces that would otherwise be unused structural material. By converting the wall's internal volume into functional storage compartments, the design provides additional storage without encroaching on passenger comfort zones or seat recline space.
3Ease of operation
If the sink is designed with standard height to provide adequate washing functionality, then passenger comfort is improved, but space above the sink for storage is reduced
Solution Approach 1:
The patent applies local quality by creating storage compartments at specific locations within the wall structure, particularly above and around the sink area. Instead of reducing sink height, the invention provides localized storage solutions within the wall thickness directly above the sink, allowing full washing functionality while maintaining storage capacity in the vertical dimension.

AI summary
An aircraft lavatory comprising an enclosure having a door, a first side wall, a rear wall, a ceiling, and a second side wall, wherein the second side wall includes a sink, the second side wall defining a plane and wherein the sink is inwardly disposed from said plane. To create space for a stowage compartment, an additional side wall parallel to, and adjacent to, said second side wall is formed. This space houses a stowage compartment accessible from outside said lavatory, the stowage compartment formed between said second side wall and said additional wall.
