Movable Partition Toilet Layout for Wheelchair Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircrafts often lack separate toilets for persons with limited mobility, which reduces operating efficiency due to space constraints and infrequent use, as standard toilets cannot accommodate wheelchairs.
Innovation Solution
A toilet arrangement comprising two adjacent compartments with a movably supported partition wall that can be converted into a single, larger compartment accessible by wheelchair, allowing for temporary wheelchair storage and assistance, without requiring additional installation space or compromising efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate toilet for persons with limited mobility is installed, then accessibility for wheelchair users is improved, but the available space for passenger seats is reduced and operating efficiency deteriorates
Solution Approach 1:
The partition wall between the two toilet compartments is made movable rather than fixed, allowing the configuration to change dynamically. During normal operation, the partition remains in place maintaining two separate compartments for standard use. When needed, the partition can be moved to combine the compartments into a larger accessible space for wheelchair users, thus adapting to different operational requirements without permanently sacrificing passenger capacity
Solution Approach 2:
The toilet arrangement serves multiple functions: it operates as two separate standard toilet compartments during normal flights, and can be transformed into a single larger accessible compartment when accommodating persons with limited mobility. This multi-functionality allows the same physical space to serve different purposes, maximizing both passenger capacity and accessibility compliance
2Adaptability or versatility
If a handicapped toilet is installed to accommodate wheelchairs, then accessibility is improved, but the installation space requirement increases and device complexity worsens
Solution Approach 1:
The toilet facility is divided into two separate compartments that can independently function as standard toilets. The partition wall between them can be moved to combine these segments when accessibility is needed, rather than requiring a completely separate dedicated handicapped toilet facility. This segmentation allows flexible reconfiguration using existing structural elements
Solution Approach 2:
The movable partition wall acts as an intermediary element that enables transformation between configurations. By moving this intermediate structure, the system can switch between having two separate compartments or one combined compartment, providing the functionality of a handicapped toilet without requiring a permanently dedicated space

AI summary
A toilet arrangement for a vehicle includes a first toilet compartment, an adjacent second toilet compartment and a partition wall situated between the first toilet compartment and the second toilet compartment, wherein the partition wall is movably supported and designed for being transferred into an open position, in which the partition between the first toilet compartment and the second toilet compartment is removed. This makes it possible to convert two relatively small toilet compartments into a larger toilet compartment that is suitable for use by persons with limited mobility.
