Solution Overview

Problem

Current crew rest compartments in aircraft are inefficiently designed, with a second bed often unused, taking up valuable space and adding unnecessary weight, and existing solutions fail to provide optimal cabin comfort and spatial separation for crew members, especially on long flights.

Innovation Solution

A modular crew rest compartment system where a first sub-module is fixed on the main deck and a second sub-module can be docked on the cargo deck, allowing for flexible configuration and separate sleeping and working areas, with the option to remove unused modules to optimize space and weight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a second bed is installed in the crew rest compartment, then sleeping capacity is improved, but weight and space are worsened

Engineering Contradiction:
Improvesleeping capacityVSAvoidaircraft weight
Core Design Contradiction:
Quantity of substanceVSWeight of moving object

Solution Approach 1:

The crew rest compartment is divided into a permanent first sub-module and a removable second sub-module. The second sub-module containing the second bed can be detached and stored when not needed, allowing the aircraft to maintain sleeping capacity when required while reducing weight and space when the second bed is not in use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The configuration of the crew rest compartment is made dynamic through the ability to dock and undock the second sub-module. This transforms the fixed configuration into a variable one, allowing optimization of weight and space based on operational requirements.

Inventive Principle:
Principle #15Dynamics

2Quantity of substance

If a second bed is installed in the crew rest compartment, then sleeping capacity is improved, but space is worsened

Engineering Contradiction:
Improvesleeping capacityVSAvoidavailable space
Core Design Contradiction:
Quantity of substanceVSVolume of moving object

Solution Approach 1:

The crew rest compartment is divided into a permanent first sub-module and a removable second sub-module. The second sub-module containing the second bed can be detached and stored when not needed, allowing the aircraft to maintain sleeping capacity when required while reducing weight and space when the second bed is not in use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second sub-module can be discarded (removed) from the crew rest compartment when the second bed is not needed, and recovered (re-installed) when sleeping capacity is required. This allows flexible management of space based on operational needs.

Inventive Principle:
Principle #34Discarding and recovering

3Reliability

If separate crew rest compartments are provided for flight crew and cabin crew, then safety separation is improved, but device complexity is worsened

Engineering Contradiction:
Improvesafety separationVSAvoidcompartment configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The crew rest compartment is divided into a permanent first sub-module and a removable second sub-module. The second sub-module containing the second bed can be detached and stored when not needed, allowing the aircraft to maintain sleeping capacity when required while reducing weight and space when the second bed is not in use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular design allows the same physical structure to serve multiple functions: providing separate crew rest compartments when both sub-modules are docked, and providing a single larger compartment when the second sub-module is removed. This multi-functionality reduces the need for separate fixed installations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Reliability

If two separate crew rest compartments are provided, then safety separation is improved, but weight is worsened

Engineering Contradiction:
Improvesafety separationVSAvoidaircraft weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The crew rest compartment is divided into a permanent first sub-module and a removable second sub-module. The second sub-module containing the second bed can be detached and stored when not needed, allowing the aircraft to maintain sleeping capacity when required while reducing weight and space when the second bed is not in use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second sub-module can be discarded (removed) from the crew rest compartment when the second bed is not needed, and recovered (re-installed) when sleeping capacity is required. This allows flexible management of space based on operational needs.

Inventive Principle:
Principle #34Discarding and recovering

AI summary

The invention relates to a living and sleeping module (100) in an aircraft for housing at least one member of an aircraft crew, the module (100) comprising a first partial module (101) designed to dock a second partial module (102). The first partial module or the second partial module comprises a connecting element (115) and the first partial module is designed to be disposed at a different vertical height of an aircraft (200) than the second partial module. The connecting element is designed such that the second partial module can be docked to the first partial module by means of the connecting element.
