Aircraft Monument Corner Bracket Fitting for Narrow Aisle Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional monument attachment systems in aircraft platforms limit the size of monuments that can be attached, restricting storage and access options, particularly in narrow aisle configurations.
Innovation Solution
A monument attachment system comprising corner bracket fittings and a filler panel that connects to both the floor and face panels, allowing for adjustable width and aisle-facing access, while preventing undesirable load sharing with the floor structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional monument attachment systems are used, then structural integrity is maintained, but monument size is limited
Solution Approach 1:
The attachment system is divided into separate corner bracket fittings that can be independently attached to each corner of the monument. Each bracket fitting connects to the floor structure and monument panel separately, allowing modular assembly and enabling larger monument dimensions while maintaining structural integrity through distributed attachment points.
Solution Approach 2:
The attachment system transitions from conventional single-plane mounting to three-dimensional corner bracket fittings that extend vertically and horizontally. The brackets attach to the floor structure at one level and connect to monument panels at another level, creating a multi-dimensional attachment geometry that accommodates larger monument sizes.
2Length of moving object
If monument width is reduced, then aisle access is improved, but attachment system reliability may be compromised
Solution Approach 1:
The corner bracket fittings are designed with asymmetric geometry where one flange extends parallel to the seat track for floor attachment while another flange extends perpendicular for monument panel attachment. This asymmetric configuration allows the brackets to securely attach narrow-width monuments to the floor structure while preventing load sharing with the monument panels themselves.
Solution Approach 2:
The corner bracket fittings serve as intermediary components between the floor structure and the monument panels. These brackets transfer loads directly to the floor structure through their seat track interfaces, preventing undesirable load sharing with the monument panels and ensuring reliable attachment even for reduced-width monuments.
3Ease of manufacture
If corner bracket fittings are used, then manufacturing flexibility is improved, but device complexity increases
Solution Approach 1:
The corner bracket fittings are designed as universal components that can be used at all four corners of any monument regardless of size or configuration. Each bracket fitting performs multiple functions: attaching to the floor structure, connecting to monument panels, and preventing load sharing. This universality simplifies manufacturing by using standardized parts across different monument types.
Solution Approach 2:
The corner bracket fitting combines multiple attachment functions into a single integrated component. Rather than using separate fasteners and brackets for each attachment point, the design merges the floor attachment flange, the monument panel connection flange, and the structural body into one unified corner bracket fitting that accomplishes all attachment tasks simultaneously.

AI summary
A monument is presented. The monument comprises a floor panel; a left face panel perpendicular to the floor panel; a right face panel perpendicular to the floor panel; and an attachment system connecting the floor panel, the left face panel, and the right face panel. The attachment system comprises a right corner bracket fitting connecting the right face panel to the floor panel; a left corner bracket fitting connecting the left face panel to the floor panel; and a filler panel connected to and extending between the right corner bracket fitting and the left corner bracket fitting.
