Telescoping Emergency Slide With Gas Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional emergency slide systems for aircraft evacuation are slow to deploy due to inflation requirements, and they lack efficient packability within the aircraft door.
Innovation Solution
A telescoping emergency slide system with interlocking nested tubes and a gas deployment device, comprising a gas generator, compressed gas cylinder, and aspirator, which automatically deploys upon opening the storage compartment, utilizing a fabric wrap for the slide surface and attachment to telescoping segments for rapid deployment and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional emergency slides are inflated to deploy, then the slide can be deployed, but the deployment time is increased
Solution Approach 1:
The slide structure is divided into multiple telescoping segments that can extend independently. Each segment contains nested tubes that slide into one another, allowing the slide to deploy in sections rather than requiring full inflation of a single large structure. This segmentation enables faster deployment as each segment can extend independently without waiting for complete inflation.
Solution Approach 2:
The invention extracts and removes the inflation mechanism entirely from the deployment process. Instead of using gas or air inflation to expand the slide, the patent uses a mechanical telescoping system where nested tubes simply slide outward under their own weight or minimal actuation. This extraction of the inflation function eliminates the time delay associated with filling large volumes with gas.
2Volume of moving object
If the emergency slide is made compact for storage, then packability is improved, but deployment speed may be reduced
Solution Approach 1:
The slide structure employs nested tubes where smaller diameter tubes are positioned inside larger diameter tubes. In the stored configuration, all tubes are retracted into one another, creating a compact cylindrical package with minimal volume. During deployment, the tubes extend outward in sequence, transforming from a compact nested state to a fully extended slide structure. This nesting principle allows the slide to achieve both compact storage and rapid deployment without compromise.
