Movable Cabin Partition Layout for Passenger-Cargo Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft designs fail to optimize the use of cabin space by not allowing for the conversion of passenger areas into cargo space when passenger load is low, resulting in underutilization of available space.
Innovation Solution
An in-cabin partition system with a slider, rotary shaft, and partition body that can be moved and rotated using a combination of linear motors and planetary gear mechanisms, controlled by a controller to adjust space layout based on passenger or cargo needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional in-cabin partition is used, then the aircraft maintains fixed passenger and cargo areas, but the aircraft cannot utilize extra or unoccupied room in the cabin to carry more cargo when passenger load is low
Solution Approach 1:
The partition body is made movable through a combination of linear motion (via slider on rail) and rotational motion (via rotary shaft), allowing it to dynamically reconfigure the cabin space between passenger and cargo areas based on operational needs
Solution Approach 2:
The partition system serves multiple functions: it can separate passenger and cargo areas during normal operations, allow full cargo access when passengers are absent, and provide flexible space reconfiguration for different operational scenarios, making the aircraft adaptable to various mission requirements
2Quantity of substance
If the aircraft is configured with a double deck, then it has dedicated passenger and cargo areas, but it is impossible to utilize extra or unoccupied room in the cabin to carry more cargo
Solution Approach 1:
The partition body transitions from a static separator to a dynamic reconfigurable element that can move along the rail and rotate to different positions, enabling the cabin to adapt its configuration to maximize cargo capacity when passenger load is low while maintaining passenger-cargo separation when needed
3Productivity
If a conventional fixed partition is used, then the cabin layout is simple and stable, but the time and process required to adapt the interior layout for optimal passenger boarding and cargo loading is excessive
Solution Approach 1:
The partition system incorporates dynamic motion capabilities through linear sliding and rotational mechanisms, enabling rapid reconfiguration of the cabin layout to optimize space utilization for different operational scenarios
Solution Approach 2:
The system combines linear motion (slider on rail) and rotational motion ( rotary shaft) into a single integrated partition mechanism, allowing the partition body to achieve complex repositioning through coordinated movement along multiple degrees of freedom

AI summary
An in-cabin partition of a mobility vehicle may allow for automatically adjusting the size of a space for passengers and cargo according to circumstances and needs. The in-cabin partition may include at least one rail installed in a cabin, a slider movably installed on the rail, a rotary shaft rotatably installed on the slider, and a partition body connected to the rotary shaft. The partition body may be configured to be rotatable with the rotary shaft.
