Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft breathing systems face challenges in quick deployment, oxygen efficiency, comfort, and size adaptability, with existing solutions often cumbersome and inefficient in emergency situations.
Innovation Solution
A breathing system with a face-fitting device, holding means, and storage means integrated into the aircraft seat, featuring removable fixing means that allow for rapid deployment and adjustable tightening mechanisms to ensure a secure fit, reducing oxygen consumption and improving user accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the face-fitting device is stored in a location that is easily accessible near the user's head, then the deployment time is reduced, but the space arrangement around the crew member's seat becomes more complex
Solution Approach 1:
The breathing system components (face-fitting device, holding means with back portion, and storage means) are merged into an integrated assembly that combines storage and deployment functions. The storage means is integrated into the seat structure, and the holding means with back portion is pre-positioned near the headrest, creating a unified system that reduces deployment time while maintaining acceptable space arrangement through functional integration rather than separate components
Solution Approach 2:
The holding means with back portion is pre-positioned and pre-assembled near the headrest in the storage configuration. The removable fixing means is pre-installed to secure the back portion to the headrest. This preliminary arrangement of components in their final deployment positions eliminates the need for complex assembly during emergency deployment, reducing deployment time while the integrated design maintains space efficiency
2Stability of the object's composition
If the back portion of the holding means is fixed to the headrest, then the device stability is improved, but the deployment speed is reduced due to additional release steps
Solution Approach 1:
The holding means is segmented into a face-fitting device portion and a back portion that can be separately secured to the headrest. The removable fixing means provides a distinct attachment interface between the back portion and headrest. This segmentation allows the back portion to be stably fixed during storage while enabling rapid release and deployment by simply removing the fixing means, rather than dealing with a monolithic fixed structure
Solution Approach 2:
The fixing means transitions the back portion from a static fixed state during storage to a mobile deployable state during emergency use. The removable nature of the fixing means allows the back portion to dynamically change its attachment status - securely fixed to headrest during normal operations, but quickly releasable and movable to the operational position when needed, balancing stability with deployment speed
3Ease of manufacture
If pneumatic tubes are inflated using breathing gas, then the implementation is simplified, but the oxygen consumption increases
Solution Approach 1:
The inflation function is extracted from the breathing gas supply system. Instead of using breathing gas to inflate the pneumatic tubes, the invention introduces a separate inflation gas supply that is dedicated solely to tube inflation. This extraction prevents the consumption of valuable breathing oxygen for the auxiliary inflation function, while the inflation system remains simple through the use of a dedicated but separate gas source

AI summary
A breathing system for an aircraft crew member or passenger may include a face-fitting device, a storage area added to a seat headrest for retaining the face-fitting device in a storage position apart from the head, and a back portion for retaining the face-fitting device on the user's head when the breathing system is used. The back portion is retained on the headrest by a removable fixing mechanism when the face-fitting device is in the storage position, and the removable fixing mechanism is released upon the tightening the face-fitting device on the user's head.
