Modular Aircraft Cabin Fluid Circuit for Movable Partition Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft cabin configurations require tedious and costly adaptations of fluid circuits when partition walls are repositioned, as they are modular and can be dismantled and reassembled to meet customer preferences, necessitating separate fluid circuits for each configuration.
Innovation Solution
Aircraft portions with fluid circuits featuring control devices that can be configured between open and closed states based on partition wall positions, allowing adaptable fluid flow without the need for separate circuits for each configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate fluid circuits are provided for each cabin configuration, then fluid supply independence is achieved, but device complexity and maintenance cost increase
Solution Approach 1:
A single fluid circuit is designed to serve multiple cabin configurations through the use of control devices that can redirect fluid flow. The circuit includes a first control device with first and second outlets that can supply fluid to different cabin portions depending on partition wall position, making the same circuit universal for both configurations without requiring separate circuits for each layout
Solution Approach 2:
The fluid circuit incorporates controllable elements (valves/control devices) that can dynamically change the fluid flow path based on the partition wall position. The first control device can switch between directing fluid to the first outlet (for first cabin portion) or second outlet (for second cabin portion), allowing the system to adapt its configuration dynamically rather than requiring fixed separate circuits
2Manufacturing precision
If fluid circuits are adapted for each partition wall position, then fluid supply accuracy is improved, but ease of manufacture and installation deteriorate
Solution Approach 1:
The fluid circuit is pre-configured with multiple outlets and control devices during manufacturing, with all necessary components (first outlet, second outlet, control devices) already in place. This preliminary preparation allows the circuit to be easily adapted to different configurations simply by operating the control devices rather than requiring complex modifications or reinstallation work
3Adaptability or versatility
If control devices are added to enable configuration adaptation, then adaptability is improved, but device complexity increases
Solution Approach 1:
The fluid circuit is segmented into distinct controllable sections with separate control devices at different points. The first control device manages flow to the first cabin portion, while the second control device manages flow to the second cabin portion. This segmentation allows independent control of different cabin portions, enabling configuration adaptation through simple on/off control of individual segments rather than complex system-wide control
Data Source
AI summary
includes a wall, mounted at a first or second coordinate, configured to separate first and second cabin portions and a circuit fluidly connecting a source and the second cabin portion. The circuit fluidly connecting a source, and the second cabin portion further includes a pipe, the pipe further including a first section delivering fluid between the first and second coordinates, a second section delivering fluid to the rear of the second coordinate and a control device. The control device is intendent to be in the open configuration or the closed configuration. In the open configuration, the first and second sections are in fluid communication, when the wall is mounted at the first coordinate or the closed. In the closed configuration, the fluid communication is interrupted, when the wall is mounted at the second coordinate.
