Planar Structural Arrangement for Aircraft Fuselage System Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of system components in aircraft fuselages is hindered by confined spaces, leading to increased assembly time and difficulties in other installation processes, particularly in areas like the tail portion where waste water tanks are located.
Innovation Solution
A method involving the use of a planar structural arrangement that is secured to or within the aircraft fuselage, allowing system components to be attached outside the fuselage, with system lines arranged underneath, forming a standalone module that can be positioned and mechanically coupled to the fuselage using support structure members and a carrier rail system, reducing the need for work in cramped spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If system components are installed manually inside the aircraft fuselage at designated locations, then the installation can be performed using existing tools and resources, but the assembly time increases and the work becomes physically difficult due to confined installation space
Solution Approach 1:
The installation process is segmented into two distinct phases: (1) pre-assembly of system components on a separate planar structural arrangement outside the fuselage, and (2) positioning and coupling of the pre-assembled module into the fuselage. This segmentation allows complex installation tasks to be performed in accessible external spaces rather than confined internal spaces, thereby improving ease of installation while reducing overall assembly time.
Solution Approach 2:
System components are preliminarily assembled and configured on the planar structural arrangement before being installed into the aircraft fuselage. This preliminary action includes securing system components, coupling system lines, and arranging all necessary elements in their final positions while working in accessible external environments, thereby eliminating the need for time-consuming work in confined spaces during final installation.
2Ease of operation
If system components are installed manually inside the aircraft fuselage, then the installation can proceed with conventional methods, but the confined installation space creates physical difficulties and hinders assembly work
Solution Approach 1:
A planar structural arrangement serves as an intermediary carrier that temporarily holds system components during pre-assembly operations. This intermediary structure provides a stable, accessible platform outside the fuselage where components can be easily manipulated and positioned, improving ergonomics of installation while the modular nature of the approach actually simplifies the overall installation process rather than increasing complexity.
3Volume of moving object
If waste water tanks are arranged in the tail portion of the fuselage with low installation space height, then the space utilization is optimized, but the assembly work becomes physically very difficult to carry out
Solution Approach 1:
The conventional approach is inverted: instead of installing system components directly into the confined fuselage space, the components are first assembled on a planar structural arrangement positioned outside the fuselage. This inversion allows assembly personnel to work in accessible external environments with adequate space and ergonomics, while the final product achieves the same compact space utilization within the fuselage tail portion.
Solution Approach 2:
The installation process transitions from working exclusively within the three-dimensional confined space of the fuselage interior to utilizing the external dimensional space around the fuselage. By positioning the planar structural arrangement outside the fuselage, the system leverages additional spatial dimensions that are not constrained by the fuselage interior geometry, thereby improving physical accessibility for assembly while maintaining compact internal packaging.

AI summary
A method is proposed for installing system components in a portion of an aircraft fuselage. The method provides at least one planar structural arrangement to be secured on or in the aircraft fuselage, secures system components on the structural arrangement, couples system lines to the system components and arranges the system lines on the structural arrangement. The method includes positioning of the structural arrangement with the system components and system lines arranged thereon at a designated installation location of the structural arrangement, and mechanical coupling of the structural arrangement to the aircraft fuselage.
