Segmented Aircraft Frame for Fuselage Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft fuselage assembly methods require extensive work and numerous fasteners, leading to increased processing time and costs due to the assembly of many single parts during joint assembly, particularly in the connection of fuselage sections.
Innovation Solution
The aircraft frame is divided into two partial frames that can be connected later, reducing the number of parts and assembly effort, with a design that optimizes load flow and incorporates multifunctional components for easier installation and maintenance, using advanced manufacturing techniques like added layer manufacturing (ALM) and lightweight materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single aircraft frame is used to connect two fuselage segments, then the structural connection is achieved, but the assembly requires extensive work with numerous fasteners and mounting pieces, increasing processing time and costs
Solution Approach 1:
The aircraft frame is divided into two partial aircraft frames that can be assembled separately and then connected. This segmentation allows for parallel assembly processes and reduces the complexity of handling a single large frame component, directly addressing the assembly effort and processing time issues.
Solution Approach 2:
The two partial aircraft frames are designed to be connected together to form the complete frame structure. This merging approach combines the benefits of segmented assembly with the structural integrity of a unified frame, eliminating the need for numerous separate mounting pieces while maintaining connection strength.
2Reliability
If traditional mounting pieces and fasteners are used to connect fuselage segments, then the connection is achieved, but the number of parts increases, leading to higher costs and more extensive assembly work
Solution Approach 1:
The connection function is integrated directly into the partial aircraft frames themselves rather than using separate mounting pieces. The frames are designed with connection interfaces that incorporate the joining function, eliminating the need for additional fasteners and mounting components while maintaining reliable structural connection.
Solution Approach 2:
The partial aircraft frames serve multiple functions: they provide structural support, enable connection between fuselage segments, and incorporate the joining mechanism themselves. This multi-functionality reduces the need for specialized mounting pieces and fasteners, simplifying the overall assembly.
3Stability of the object's composition
If extensive assembly work is performed to connect fuselage segments, then the joint is permanently secured, but the processing time and costs increase significantly
Solution Approach 1:
By dividing the frame into two partial frames that can be assembled separately, the assembly process can be performed in parallel on different fuselage segments, then the frames are connected together. This segmentation enables more efficient workflow and reduces the sequential assembly time while maintaining permanent joint stability.
Solution Approach 2:
The partial aircraft frames are pre-assembled and prepared before final connection to the fuselage segments. This preliminary action allows for quality control and preparation work to be done in advance, reducing the time required during final assembly while ensuring stable permanent connections.
