Movable In-Cabin Partition for Passenger-Cargo Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft designs fail to efficiently utilize extra cabin space for cargo when passenger capacity is low, limiting the flexibility in optimizing passenger and cargo capacity utilization.
Innovation Solution
An in-cabin partition system with rails, sliders, rotary shafts, and partition bodies that can be moved and rotated using linear motors and planetary gear mechanisms, controlled by a computing device to adjust the cabin layout based on passenger and cargo needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the aircraft uses a double deck configuration with fixed passenger and cargo areas, then the structural stability is maintained, but the adaptability of space utilization deteriorates when passenger numbers vary
Solution Approach 1:
The partition body is designed to be movable rather than fixed, allowing it to change position along the longitudinal direction of the aircraft. The partition can be adjusted to different locations to accommodate varying passenger and cargo needs, transforming a static space division into a dynamic one that adapts to different operational requirements
Solution Approach 2:
The partition system is divided into separate functional components: a partition body for space division, a support structure with rails for movement, and a drive mechanism with motors and gears for actuation. This segmentation allows each component to be optimized independently and facilitates the overall adaptability of the system
2Productivity
If the aircraft maintains exclusive separate areas for passengers and cargo, then the reliability of dedicated function is improved, but the productivity of space utilization deteriorates when one area is underutilized
Solution Approach 1:
The movable partition system enables the aircraft cabin to serve multiple functions: during high passenger demand flights, the partition separates passenger and cargo areas; during low passenger demand flights, the partition can be repositioned or removed to convert passenger space into cargo space, allowing the same physical space to fulfill different operational roles
3Speed
If manual adjustment of partition position is used, then the device complexity is reduced, but the speed of space reconfiguration deteriorates
Solution Approach 1:
The manual mechanical adjustment system is replaced with an automated electromechanical system. Motors mounted on the partition body interact with gear mechanisms and rail systems to automatically position the partition at desired locations, eliminating the need for manual operation and significantly reducing reconfiguration time

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.
