Solution Overview

Problem

Existing aircraft lavatory designs often compromise on space efficiency and accessibility for handicapped passengers, as they require additional space or complex reconfiguration, which can be difficult to implement and may limit access in other areas.

Innovation Solution

A moveable partition system that allows two lavatories to be configured as separate spaces or combined into a single space within a fixed perimeter, with doors that open to form an unobstructed entrance, providing flexible access without altering the lavatory perimeter.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If lavatories are redesigned to extend into space normally used for aisles or other purposes to provide handicap access, then accessibility for handicapped passengers is improved, but device complexity and difficulty of reconfiguration increase

Engineering Contradiction:
Improveaccessibility for handicapped passengersVSAvoiddifficulty of reconfiguration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The partition wall is made movable rather than fixed, allowing it to be repositioned between different configurations. This dynamic element enables the lavatory to adapt between a standard configuration and a handicap-accessible configuration by simply moving the partition, rather than requiring complex structural changes or permanent modifications to the aircraft interior.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The partition wall is divided into multiple sections that can be independently moved or repositioned. This segmentation allows for flexible reconfiguration where the partition can be adjusted to create the necessary space for handicap access without requiring the entire lavatory structure to be modified, thereby reducing overall system complexity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If two lavatories are positioned next to each other and reconfigured to provide more access for handicapped passengers, then accessibility is improved, but the difficulty of reconfiguration increases

Engineering Contradiction:
Improveaccess space for handicapped passengersVSAvoidreconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The partition between the two lavatories is made movable, allowing it to be shifted to combine the two spaces when handicap access is needed. This dynamic reconfiguration is achieved through simple mechanical means rather than complex structural changes, enabling the system to provide increased access space while maintaining ease of reconfiguration.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a moveable partition is used to separate or combine lavatories, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveflexibility in lavatory configurationVSAvoidpartition system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The partition is designed as a movable element that can be repositioned along a track or guide system, providing adaptability between different lavatory configurations. The movement mechanism is kept simple, using basic mechanical components rather than complex automated systems, thereby achieving flexibility while minimizing the increase in device complexity.

Inventive Principle:
Principle #15Dynamics

AI summary

A method and apparatus for reconfiguring a lavatory area. An apparatus comprises a first lavatory area, a second lavatory area, a first door for the first lavatory area, and a second door for the second lavatory area. The first door and the second door are configured to move between an open position and a closed position. A single passageway is present in both the first lavatory area and the second lavatory area when the first door and the second door are in the open position.
