Swing-Action Aircraft Floor Cladding for Rapid Cargo Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conversion of an aircraft's passenger cabin to a cargo space is time-consuming, leading to lengthy downtimes and increased costs due to the need for extensive reconfiguration and gas-tight partitioning to prevent fumes from entering passenger areas.
Innovation Solution
An aircraft-floor element with a swing-action cladding system that can pivot from a passenger cabin configuration to a cargo space configuration, utilizing hinges or releasable fastenings, and incorporating sealing elements for gas-tight and liquid-tight terminations to protect against hazardous substances and liquids, allowing rapid conversion without the need for external components or technical aids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive reconfiguration and gas-tight partitioning are used to convert passenger cabin to cargo space, then safety and gas-tight separation are improved, but conversion time and downtime increase
Solution Approach 1:
The aircraft floor element is divided into multiple cladding elements (first cladding element, second cladding element, third cladding element) that can be independently positioned. Each cladding element can be swung between first position (passenger cabin configuration) and second position (cargo space configuration), allowing modular and rapid reconfiguration of the space while maintaining gas-tight separation when needed.
Solution Approach 2:
The cladding elements are designed to be movable rather than fixed, enabling dynamic reconfiguration of the aircraft interior. The elements can be quickly swung between positions to convert the space from passenger cabin to cargo space and back, reducing conversion time while maintaining the ability to provide gas-tight partitioning when required.
2Reliability
If fixed cladding elements are used to ensure gas-tight partitioning, then safety is improved, but adaptability and conversion speed deteriorate
Solution Approach 1:
The same cladding elements serve multiple functions: they form the boundary of the passenger cabin when in the first position, and form the boundary of the cargo space when in the second position. This multi-functionality allows the aircraft interior to be rapidly converted between configurations while the cladding elements maintain gas-tight separation capability in both modes.
Solution Approach 2:
The cladding elements transition from fixed to movable during conversion, then become fixed again in the new configuration. This dynamic behavior enables both adaptability (quick conversion) and reliability (gas-tight partitioning) - the elements are fixed when providing separation but can be moved when conversion is needed.
3Productivity
If rapid conversion system is implemented, then productivity and operational efficiency are improved, but device complexity increases
Solution Approach 1:
The complex conversion task is divided into simpler sub-tasks by segmenting the floor element into multiple independent cladding elements. Each element can be swung independently between positions, making the overall conversion process simpler and more manageable than moving a single large structure, thereby improving productivity without excessive complexity.
Solution Approach 2:
Multiple cladding elements are combined into a single integrated floor element structure that shares common support elements. This merging reduces the overall complexity compared to having completely separate movable structures, while still allowing rapid conversion through the coordinated movement of the segmented cladding elements.

AI summary
An aircraft-floor element comprising a first cladding element configure to be swung from a first position to a second position. In the first position, the first cladding element is arranged parallel to a main plane of the aircraft-floor element and on a side of the aircraft-floor element which is directed towards a passenger cabin. In the second position, the first cladding is arranged at an angle to the main plane of the aircraft-floor element, wherein it forms a cladding for a cargo space. An aircraft zone having an aircraft-floor element and an aircraft having such an aircraft zone are also disclosed.
