Aircraft Cabin Floor Fixation Interface With Segmented Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft cabin floor fixations are heavy and lack effective sealing, which can create obstacles for passengers and compromise the integrity of the cabin environment.
Innovation Solution
An adaptable fixation interface comprising connection studs with a mounting foot region and a connection head region, allowing for releasable connection to interface points in the floor arrangement, providing a lightweight and sealable fixation solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional seat rails are provided throughout the cabin space, then sealing capacity is improved, but weight increases
Solution Approach 1:
The fixation interface is divided into discrete connection studs positioned at specific interface points along the floor support structure, rather than providing continuous rails throughout the cabin. This segmentation allows sealing to be provided only where equipment mounting is required, reducing overall weight while maintaining sealing capacity at critical locations.
Solution Approach 2:
The connection studs are strategically positioned at specific interface points where equipment mounting is needed, providing localized sealing and fixation capability. This local quality approach ensures sealing is present only where required rather than uniformly throughout the entire cabin length, optimizing the weight-sealing tradeoff.
2Adaptability or versatility
If connection studs are positioned at multiple interface points, then adaptability for equipment mounting is improved, but device complexity increases
Solution Approach 1:
The connection studs are designed with universal functionality to engage with equipment fittings at multiple interface points along the floor support structure. Each connection stud provides the same mounting capability, allowing flexible equipment placement without requiring different fixation components for different locations, thus maintaining simplicity while achieving adaptability.
Solution Approach 2:
The fixation interface allows dynamic configuration of equipment placement by positioning connection studs at multiple discrete interface points along the floor support structure. This enables the mounting system to adapt to different equipment layouts and cabin configurations while maintaining a simple standardized connection stud design at each point.

AI summary
The present invention relates to fixations in a floor area of an aircraft. In order to provide a light weight fixation interface with improved sealing, an adaptable fixation interface (10) for an aircraft cabin floor is provided. The interface comprises a plurality of connection studs (12) that comprise a mounting foot region (14) and a connection head region (16). The mounting foot region is configured to be inserted into one of a plurality of interface points in a floor arrangement. The connection head region is configured to be engaged by a fitting of an equipment to be fixed to the floor arrangement. The connection studs are configured to be releasably connected to adjacent interface points in a floor arrangement to provide a longitudinally extending fixation interface segment for mounting of equipment.
