Aircraft Lavatory Segmentation for Larger, Accessible Interior Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft lavatories are typically small and confining due to space and size constraints, limiting passenger comfort and accessibility.
Innovation Solution
The design of a larger aircraft lavatory with an upper portion extending over seats, separateable walls for transportation, and enhanced storage compartments, allowing for increased interior space and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the lavatory monument is designed to fit through the aircraft door, then the lavatory can be installed in the aircraft, but the lavatory size is constrained and remains small
Solution Approach 1:
The lavatory monument is divided into separate wall sections (inboard wall with opening, outboard wall, forward wall with upper and lower portions, aft wall) that can be transported independently through the aircraft door and then assembled inside the aircraft cabin. This segmentation allows each component to fit through the door while the complete assembled structure provides a larger lavatory volume than would be possible if the entire monument had to fit through the door as a single unit.
2Ease of operation
If the lavatory size is increased to improve passenger comfort, then passenger comfort and accessibility are improved, but the lavatory may not fit through the aircraft door for installation
Solution Approach 1:
By segmenting the lavatory into transportable wall sections that assemble inside the aircraft, the design achieves larger overall dimensions that improve passenger comfort and accessibility while maintaining compatibility with standard aircraft door dimensions for installation.
Solution Approach 2:
The inboard wall includes an opening that allows access to the lavatory without requiring the entire lavatory structure to pass through the door. This dimensional approach - creating an opening in one wall while assembling other walls separately - enables the lavatory to achieve greater size while still fitting through the aircraft door during installation.
3Ease of operation
If the inboard wall includes an opening for access, then passenger accessibility is improved, but the wall structure becomes more complex
Solution Approach 1:
The lavatory is segmented into multiple wall portions that can be manufactured and transported separately. The inboard wall with its access opening is one such segment, and by designing it as a separate transportable unit, the complexity of the opening structure is managed more easily compared to attempting to create the same opening in a monolithic wall structure.

AI summary
An aircraft lavatory is disclosed herein. The aircraft lavatory includes an aft wall (204), a forward wall (202) including an upper portion (220) and a lower portion (218), the lower portion configured to be directly adjacent one or more seats (216), and the upper portion configured to extend away from the forward wall and over the one or more seats, an outboard wall (206) coupled to the forward wall and the aft wall, and an inboard wall (208) coupled to the forward wall and the aft wall, the inboard wall defining an opening to access the aircraft lavatory, wherein each of the outboard wall and the inboard wall are configured to be separated into an aft side and a forward side.
