Aircraft Interior Component Suspended Mounting System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The final mounting of aircraft interior components is time-consuming due to the need for precise positioning and challenging connection of supply lines in the limited space of an aircraft cabin, making it difficult to handle large modules efficiently.
Innovation Solution
An aircraft interior component system featuring a suspended mounting mechanism with structure and component holders that create a mounting gap, allowing for quick attachment and access, along with a method for connecting supply lines through complementary connecting devices within this gap, enabling flexible and efficient installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If interior components are fastened individually to the aircraft structure with precise positioning, then the components can be securely mounted, but the mounting process becomes very time-consuming
Solution Approach 1:
The aircraft interior is divided into modular components (side covering panels, dado panels, overhead luggage compartments, personal service units) that can be preassembled into larger modules outside the aircraft, then installed as complete modules, reducing the number of individual positioning operations required
Solution Approach 2:
Interior components are preassembled and tested extensively outside the aircraft before final installation. Large modules comprising multiple components are prepared in advance, allowing for quality control and positioning adjustments to be made before the time-sensitive final mounting operation
2Productivity
If large modules comprising multiple interior components are preassembled outside the aircraft, then mounting time is reduced, but the modules become difficult to handle and position
Solution Approach 1:
The system allows for hierarchical modularity where interior components can be assembled into modules of appropriate size - not necessarily all components in one large module, but divided into manageable sections that can be handled and positioned separately, then connected
Solution Approach 2:
A transporting apparatus with holding devices serves as an intermediary system to support and position the preassembled modules during installation, making it easier to handle large modules by distributing the support across multiple holding points rather than requiring manual positioning
3Manufacturing precision
If supply lines are connected individually for each component during final mounting, then precise connections can be made, but the limited mounting space makes the process comparatively difficult
Solution Approach 1:
Supply lines are organized by module rather than by individual component. Each preassembled module has its supply lines bundled and connected at module-level connection points, reducing the complexity of wire management in the limited mounting space during final installation
Solution Approach 2:
Supply line connections are pre-routed and prepared within each module during the preassembly phase outside the aircraft. This allows for precise connection planning and testing to be done in advance, so that during final mounting, only the interface connections between modules need to be made

AI summary
An aircraft interior component system (10) comprises an aircraft interior component (12), a first structure holder (27), which is fastened to an element (26) of the aircraft structure, and a first component holder (30), which is fastened to the aircraft interior component (12) and is complementary to the first structure holder (27). The first component holder (30) is fastened to the aircraft interior component (12) in a first region (28) of the aircraft interior component (12) which faces an aircraft cabin ceiling when the aircraft interior component (12) is mounted in an aircraft. The first structure holder (27) and the first component holder (30) are designed to attach the aircraft interior component (12) in a suspended manner to the element (26) of the aircraft structure. The aircraft interior component (12) is configured such that, when the aircraft interior component (12) is attached in a suspended manner to the element (26) of the aircraft structure, a mounting gap (40) is present, at least in a second region (32) of the aircraft interior component (12) which faces an aircraft cabin floor (34) when the aircraft interior component (12) is mounted in an aircraft, between a rear side (36) of the aircraft interior component (12) and an aircraft component (38) opposite the rear side (36) of the aircraft interior component (12).
