Aircraft Cabin Fastening Substructure for Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft cabin fastening systems are not optimal for reconfiguring aircraft into different purposes, such as VIP or hospital aircraft, as they are geared towards standard passenger cabin configurations, and adding new points of attachment can be impractical and require extensive approvals.
Innovation Solution
An apparatus comprising a substructure with vertically arranged supports and a connecting panel that can be fastened at existing points of attachment on the aircraft structure, allowing flexible fastening of cabin components without the need for new, authorization-dependent points of attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional points of attachment are provided on the aircraft structure for reconfiguration purposes, then the adaptability for different cabin configurations is improved, but the device complexity and approval requirements increase
Solution Approach 1:
The patent introduces an intermediary substructure (support structure with mounting brackets) that mediates between the existing aircraft structure and the new cabin fittings. This substructure attaches to existing points of attachment and provides additional mounting locations, thereby enabling reconfiguration without modifying the aircraft structure itself and avoiding complex approval processes.
Solution Approach 2:
The fastening system is segmented into separate functional components: the support structure that attaches to the aircraft, the mounting brackets that provide attachment points, and the cabin fittings that are mounted. This segmentation allows the support structure to be universally applied to existing aircraft while accommodating various cabin configurations through the modular mounting brackets.
2Adaptability or versatility
If new points of attachment are created on the aircraft structure, then the versatility for different purposes is improved, but the weight of the aircraft structure increases
Solution Approach 1:
The support structure acts as an intermediary that provides the necessary attachment points without becoming part of the aircraft structure. By using existing structural points of attachment and adding only the necessary mounting brackets and support elements, the solution enables versatility while minimizing weight additions to the aircraft structure.
3Ease of manufacture
If standardized points of attachment are used for cabin fittings, then the ease of manufacture is improved, but the adaptability for different cabin configurations is reduced
Solution Approach 1:
The support structure and mounting brackets are designed as universal components that can accommodate various cabin configurations and fittings. The standardized attachment interface on the support structure allows different cabin fittings to be mounted using the same base structure, thereby maintaining ease of manufacture while achieving high adaptability for different purposes.

AI summary
An apparatus fastens cabin components in a region of side walls, which belong to an aircraft structure and extend in a vertical direction in relation to a horizontal cabin floor. The apparatus includes a substructure, which includes: at least two supports, which are vertically arrangable on a side wall, of the sidewalls of the aircraft structure, are spaced apart in a horizontal direction, are designed in each case for fastening at at least two vertically spaced-apart defined points of attachment of the aircraft structure in the region of the side wall, and at least one panel, which connects the supports in the horizontal direction and is designed for connecting to the supports, each connected by the panel, at two vertically spaced-apart points of connection. Both the at least two supports and the at least one panel are designed in order for cabin components to be fastened thereon.
