Aircraft Furniture Baseframe Connection for Floor Deflection Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft furniture is prone to disengagement and damage due to deflections in the aircraft floor, compromising the connection between the furniture and the mounting track.
Innovation Solution
A mounting system with base frames and connectors that allow simultaneous movement in both lateral and longitudinal directions, absorbing deflections while maintaining a fixed connection to the mounting track.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed connection is used between aircraft furniture and mounting track, then the furniture is securely mounted, but the connection is compromised by floor deflections causing disengagement and damage
Solution Approach 1:
The mounting system transitions from a fixed rigid connection to a dynamic connection that allows movement. The base frame incorporates connectors that can move relative to the aircraft furniture, enabling the system to adapt to floor deflections while maintaining secure attachment. This dynamic capability prevents disengagement and damage by absorbing dimensional changes through controlled movement rather than rigid constraint.
Solution Approach 2:
The system changes the physical state of the connection from fixed to movable by incorporating sliding mechanisms and flexible elements. The base frame allows for longitudinal and lateral movement of connectors, changing the parameter of connection rigidity to accommodate floor deflections. This parameter change enables the system to maintain reliability under varying dimensional conditions.
2Object-affected harmful factors
If a movable connection is introduced to accommodate floor deflections, then damage is reduced, but the connection stability is compromised
Solution Approach 1:
The mounting system is divided into separate functional components: the base frame, connectors, and aircraft furniture attachment points. This segmentation allows different parts to perform specialized functions - the base frame provides structural support, the connectors enable controlled movement, and the attachment points secure the furniture. This division maintains overall stability while allowing necessary movement to reduce damage.
Solution Approach 2:
The connectors act as intermediary elements between the base frame and the aircraft furniture. These intermediaries absorb the movement caused by floor deflections through their sliding and flexible mechanisms, preventing direct transmission of harmful forces to the furniture while maintaining stable attachment. The intermediary components bridge the gap between rigid structural requirements and flexible adaptation needs.

AI summary
Described are mounting assemblies for an item of aircraft furniture in an aircraft. The mounting assemblies each include a base, a first connector, and a second connector. The base includes a first slot elongated in a first direction and a second slot elongated in a second direction. The first connector is retained within and is movable within the first slot, and the second connector is retained within and is movable within the second slot. The first connector and the second connector may be simultaneously movable in the first direction and the second direction.
