Transverse Framework for Aircraft Avionics Bay Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing avionics bay arrangement in aircraft is not optimal in terms of compactness, leading to inefficient use of space and reduced volume for the luggage bay.
Innovation Solution
A transverse framework with a mesh structure comprising vertical and horizontal connecting rods, uprights, and longitudinal members, which optimizes space by occupying part of the passageway between longitudinal avionics racks, allowing all equipment to be accessible from the clear zone or luggage bay, and includes oblique reinforcers and inclined hangers for load absorption and reduced fixing points.

Engineering Contradiction Analysis
1Volume of moving object
If longitudinal avionics racks are arranged parallel to the longitudinal axis with a passageway between them, then equipment accessibility is maintained, but the space occupied by the avionics bay increases and the luggage bay volume decreases
Solution Approach 1:
The patent transitions from a longitudinal arrangement of avionics racks to a transverse framework arrangement perpendicular to the longitudinal axis. This dimensional change allows equipment to be accessible from the lateral sides through the mesh structure, eliminating the need for a longitudinal passageway and thereby maximizing luggage bay volume.
Solution Approach 2:
The framework is divided into a mesh structure with vertical connecting rods, horizontal transverse members, and uprights that create multiple access points. This segmentation allows equipment to be accessed from multiple directions simultaneously, replacing the single passageway approach with distributed access points around the periphery.
2Volume of moving object
If the transverse framework uses a mesh structure with multiple connecting elements, then space optimization is achieved, but the device complexity increases
Solution Approach 1:
The mesh framework structure serves multiple functions simultaneously: it provides structural support for avionics equipment, defines the avionics bay boundaries, enables lateral equipment accessibility, and optimizes space distribution. This multi-functionality reduces the need for separate specialized components, thereby managing complexity despite the mesh configuration.
Solution Approach 2:
The patent combines the structural support function, the boundary definition function, and the equipment mounting function into a single integrated mesh framework. By merging these functions into one structure rather than using separate components, the overall device complexity is managed while achieving space optimization.
3Loss of time
If the framework minimizes connections with the primary structure, then assembly time is reduced, but the structural stability may be compromised
Solution Approach 1:
The framework is designed as a pre-assembled module with internal stability provided by the mesh structure's inherent rigidity and the triangulation effects created by the uprights and transverse members. This preliminary stabilization allows the framework to be installed as a complete unit with minimal connections to the primary structure, reducing assembly time while maintaining stability through its own internal geometry.
Solution Approach 2:
The mesh framework employs geometric configurations with triangular and rectangular cells that provide structural rigidity through their shape characteristics. These geometric forms inherently resist deformation, allowing the framework to maintain stability with fewer external connection points to the primary aircraft structure.

AI summary
A transverse framework for an avionics bay of an aircraft is delimited by a primary structure and a floor, the transverse framework having a mesh structure with square and/or rectangular mesh cells. According to one arrangement, an avionics bay of an aircraft includes two longitudinal rows of avionics racks, parallel to the longitudinal direction and arranged on each side of a clear zone, and a transverse avionics rack supported by the transverse framework situated to the rear of the two longitudinal rows of avionics racks at the rear boundary of the avionics bay. This transverse framework makes it possible to optimize the space occupied by the avionics bay.
