Aircraft Cabin Curtain Mounting for Tool-Free Crew Rest Privacy

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing aircraft cabin curtains for creating rest spaces around business class seats pose aesthetic and integration issues, require bulky modules, and lack clear communication of their purpose, leading to discomfort and potential embarrassment for crew members.

Innovation Solution

A removable holding device for an isolating curtain that suspends from a compartment without tools, using weighted bars, hooks, and magnets, allowing manual deployment and storage, and integrates seamlessly with the cabin without visible fixtures, accompanied by customizable curtains with markings to clarify their function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If exposed rails are installed to hold curtains, then curtains can be suspended to provide privacy and light protection, but the aesthetic appearance and perceived quality of the cabin are degraded

Engineering Contradiction:

Improvecurtain suspension capabilityVSAvoidcabin aesthetic appearance

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The patent removes the exposed rail structure from the cabin interior by integrating the curtain holding mechanism into the overhead compartment. The curtain is attached to the compartment itself, extracting the unsightly rail element while preserving the curtain's privacy and light-blocking functions.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The curtain storage and suspension system is nested within the overhead compartment structure. When not in use, the curtain is stored inside the compartment; when needed, it is suspended from the compartment's internal structure, eliminating the need for separate external rails.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If external rails are added to the cabin, then curtains can be installed for crew member privacy, but safety issues arise in the event of a crash

Engineering Contradiction:

Improveprivacy protectionVSAvoidcrash safety

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the curtain support system from the traditional external rail configuration and relocates it to the overhead compartment structure, which is an integral part of the aircraft cabin design and meets safety requirements.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The curtain suspension system is merged with the overhead compartment structure, combining two functions (storage and curtain support) into a single integrated component that adheres to aircraft safety standards.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If curtains are installed without clear function communication, then privacy protection is provided, but passengers may question their function and disturb crew members out of curiosity

Engineering Contradiction:

Improveprivacy protectionVSAvoidfunction communication to passengers

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent uses visual markers such as colored strips or symbols on the curtain to communicate its function to passengers. These visual cues indicate that the curtain is for crew rest purposes, preventing unnecessary curiosity and disturbance while maintaining privacy when deployed.

Inventive Principle:

Principle #32Color changes

4Reliability

If bulky modules are installed for curtain support, then curtains can be suspended effectively, but the device complexity and visual impact increase

Engineering Contradiction:

Improvecurtain suspension effectivenessVSAvoidsupport structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent eliminates bulky support modules by using the overhead compartment's existing structure to hold and suspend the curtain. The compartment itself serves as the support mechanism, removing the need for additional complex hardware.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The overhead compartment serves multiple functions: it acts as both a storage compartment and a curtain support structure. This multi-functionality reduces the need for separate dedicated curtain support mechanisms, simplifying the overall system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An assembly for an aircraft cabin includes at least one seat unit including a seat and a privacy shell extending at least partially around the seat, a compartment, such as a luggage compartment, at least one isolating curtain added to the compartment, and a removable device for holding the isolating curtain. The removable device being configured to hold the isolating curtain suspended from the compartment, so as to at least partially define a closed rest space around the seat unit and to permit manual detachment of the isolating curtain from the compartment without requiring a tool.
