Aircraft Cabin Divider Holding Device With Interlocking Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cabin class divider attachment systems in aircraft are complex and require skilled personnel for installation, posing challenges in ease of use and security during turbulence or crashes.
Innovation Solution
A holding device comprising an upper inboard attachment connected to the overhead bin structure and a lower inboard fitting connected to the movable class divider, allowing for a decoupled and simplified attachment process, with a locking element ensuring secure alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a solid cabin class divider is fitted with inboard fitting into inboard attachment assembly and pushed upwards in rotary movement, then the class divider can be securely locked into position within PSU, but the installation process becomes complex and requires trained personnel
Solution Approach 1:
The attachment system is divided into separate components: an inboard attachment assembly that connects to the overhead bin structure and an inboard fitting that attaches to the class divider. This segmentation allows each component to be optimized independently and simplifies the overall installation process by reducing the number of steps required.
Solution Approach 2:
A connection protrusion with a first bore acts as an intermediary element between the inboard attachment assembly and the inboard fitting. The connection protrusion includes a connection surface that interfaces with the overhead bin structure, while the first bore receives a locking element that secures the inboard fitting, thereby mediating the connection between different parts of the system.
2Reliability
If exact alignment is critical to ensure secure locking, then the class divider will not fall down during crash or turbulence, but the alignment process becomes difficult and time-consuming
Solution Approach 1:
The connection protrusion is designed with a connection surface that provides a reliable interface with the overhead bin structure. The first bore is positioned to receive the locking element in a way that ensures proper alignment is achieved easily during installation, making the alignment process straightforward while maintaining security during crash or turbulence.
3Reliability
If the class divider is firmly attached in the corridor area to withstand handloads, then safety is improved, but the attachment system becomes more complex
Solution Approach 1:
The attachment system is segmented into distinct functional components: the inboard attachment assembly for overhead bin connection, the connection protrusion for intermediate connection, and the inboard fitting for class divider attachment. This segmentation allows each component to be optimized for its specific function while maintaining overall system simplicity.
