Aircraft Cabin Preassembly Device and Integration Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The final assembly of aircraft cabins is costly and time-consuming due to the serial assembly of lining panels, overhead stowage bins, and supply ducts, which increases throughput time and assembly effort.
Innovation Solution
An assembly device with a frame that allows pre-assembly of aircraft cabin parts, such as sidewall panels and overhead stowage bins, using a transportation system like a rail system to slide pre-assembled components into an open section of the aircraft structure, reducing mechanical loads and enabling parallel assembly activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If serial assembly of lining panels, overhead stowage bins, and supply ducts is used in the aircraft structure, then assembly precision is maintained, but assembly time and throughput time increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-assembling cabin components (lining panels, overhead stowage bins, supply ducts) in a separate assembly device before integrating them into the aircraft structure. This allows these components to be prepared in advance and then installed as a pre-assembled unit, significantly reducing the time required for final assembly while maintaining assembly precision through controlled pre-assembly conditions
2Productivity
If pre-assembly of cabin parts is performed outside the aircraft structure, then parallel assembly activities are enabled and throughput time is reduced, but mechanical loads and stress on components increase
Solution Approach 1:
The patent introduces an intermediary assembly device that serves as a temporary support structure for pre-assembling cabin components. This intermediary device distributes mechanical loads during pre-assembly and provides controlled conditions for component integration, reducing stress on the actual aircraft structure while enabling parallel assembly activities and improving throughput time
3Ease of manufacture
If multiple cabin components are assembled serially within the aircraft structure, then component integration is simplified, but assembly effort and cost increase
Solution Approach 1:
The patent applies segmentation by dividing the assembly process into distinct phases: pre-assembly of individual cabin components (lining panels, overhead stowage bins, supply ducts) in a separate assembly device, and subsequent integration into the aircraft structure. This segmentation reduces assembly effort by allowing specialized pre-assembly operations and simplifies component integration by delivering pre-configured modules to the aircraft structure

AI summary
According to an exemplary embodiment of the invention, pre-assembly and integration of part of an aircraft cabin takes place outside the aircraft structure by means of an assembly device. After pre-assembly, the part of the aircraft cabin is slid into the open section of the aircraft structure where it is installed.
