Aircraft Interior Carrier System for Modular Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current methods for installing interior components in aircraft are time-consuming and inefficient, as each component must be individually connected and fastened to the aircraft structure, limiting the use of space between components and primary structure due to accessibility issues.
Innovation Solution
An interior component carrier system with installation rails and carrier elements that allow for pre-assembly and secure connection to the aircraft structure, enabling efficient installation and utilization of space, including the use of an attachment device for easy integration of components like overhead luggage compartments without direct connection to the primary structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interior components are connected individually to the aircraft structure, then each component can be securely fastened, but the installation process becomes very time-consuming
Solution Approach 1:
The patent combines multiple interior components (overhead luggage compartments, personal service units, piping, wiring) into a single integrated carrier system that is mounted as one unit to the aircraft structure, rather than installing each component separately. This merging of components into a modular assembly dramatically reduces installation time while maintaining secure fastening through the unified carrier system.
Solution Approach 2:
The carrier system is pre-assembled with multiple interior components attached before installation in the aircraft. This preliminary assembly allows components to be pre-positioned and pre-connected, eliminating the need for sequential installation of each component during the aircraft assembly process, thereby reducing overall installation time.
2Productivity
If large interior components are installed first, then the main structure is accessible, but areas between components and primary structure become inaccessible for further installations
Solution Approach 1:
The patent segments the interior components into modular units mounted on the carrier system, which allows wiring and piping to be routed through and around these modular segments. This segmentation creates accessible pathways between components and the primary structure, enabling installation of supply systems without requiring complete disassembly or providing access to previously blocked areas.
Solution Approach 2:
The carrier system acts as an intermediary structure between the interior components and the aircraft primary structure. It provides a mounted platform that allows wiring and piping to be installed in the spaces between components and the aircraft structure, facilitating access to areas that would otherwise be inaccessible after large components are installed.
3Adaptability or versatility
If components are mounted individually, then flexibility in positioning is maintained, but the utilization of limited installation space is reduced
Solution Approach 1:
The carrier system is designed as a universal mounting structure that can accommodate multiple different interior components (overhead luggage compartments, personal service units, piping, wiring) in various configurations. This multi-functional carrier allows flexible positioning of different components while maximizing the utilization of limited installation space through optimized arrangement of multiple components on the same carrier.

AI summary
An interior component carrier system comprises a first and second installation rail. Each rail includes at least one connecting portion connectable to an associated primary structure component to fasten the rail to the component, and a carrier portion extending from the connecting portion in a direction along a longitudinal axis of the system. The system further comprises a first carrier element having a first end connected to a first carrier rod extending in a direction along the longitudinal axis and a second end connectable to a first interior component, wherein the first carrier rod is fastened to the carrier portion of the first rail, and a second carrier element having a first end connected to a second carrier rod extending in the longitudinal axis direction and a second end connected to the first carrier element, wherein the second carrier rod is fastened to the second rail carrier portion.
