Aircraft Monument Floor Mounting for Reconfigurable Load Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monument systems in commercial aircraft cabins face challenges in being both releasably mounted for reconfiguration and rigidly secured to meet industry load requirements, particularly under static and dynamic conditions as dictated by federal regulations.
Innovation Solution
A mounting system comprising a monument partition with a mounting structure and securement apparatus, including a threaded fastener and bridging washer, that secures the monument to the aircraft floor through a floor track, allowing for adjustment and sealing while ensuring structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If monument structures are releasably mounted for reconfiguration, then adaptability is improved, but structural strength deteriorates
Solution Approach 1:
The mounting system employs a dynamic securement mechanism where monument structures can be selectively secured or released. The securement apparatus includes movable securing elements that can transition between locked and unlocked positions, allowing the structure to adapt between fixed and reconfigurable states based on operational requirements.
Solution Approach 2:
The mounting system divides the securement function into separate modular components: mounting structures attached to monument partitions, floor tracks embedded in the aircraft floor, and securement apparatus with independent securing elements. This segmentation allows individual components to be adjusted or replaced without affecting the entire system, enabling reconfiguration while maintaining overall structural integrity.
2Strength
If monument structures are rigidly secured to meet load requirements, then strength is improved, but adaptability deteriorates
Solution Approach 1:
The system provides dynamic securement where the mounting structures and securement apparatus can transition between rigidly locked positions (for meeting load requirements) and released positions (for reconfiguration). The securement elements are designed to provide full structural support when engaged, then can be cleanly released when reconfiguration is needed.
Solution Approach 2:
The floor track acts as an intermediary element between the monument structures and the aircraft floor. It provides a guided pathway that maintains structural integrity during secured operation while allowing controlled movement and repositioning when the securement apparatus is released, mediating between the conflicting requirements of strength and adaptability.
3Area of stationary object
If multiple structures are spaced within one inch of one another, then space utilization is improved, but load sharing complexity increases
Solution Approach 1:
The floor track system merges the support function for multiple closely-spaced monument structures into a single integrated floor-mounted component. The floor track is designed to distribute and share loads from multiple adjacent structures simultaneously, eliminating the need for separate complex mounting systems for each structure and simplifying the load-sharing mechanism.

AI summary
A system for mounting an aircraft monument partition to an aircraft cabin surface such as a floor may include a mounting structure fitted within and attached to a floor-abutting edge of the monument partition, the mounting structure including a mounting opening. A securement apparatus for securing the monument partition to cabin surface via the mounting structure may include a threaded fastener for extending through the mounting opening of the mounting structure and through a corresponding opening in a track mounted to the cabin surface, and a bridging washer for mating with the mounting opening; where, to secure the monument partition to the floor of the cabin area, the threaded fastener is provided through the mounting opening of the mounting structure and threaded to a mating fixture on a bottom side of the track.
