Aircraft Interior Module Transport Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current method of mounting interior components in aircraft is time-consuming, as each component must be individually positioned and fastened to the aircraft structure, and subsequent checks for leaks or interface functionality are laborious due to limited accessibility.
Innovation Solution
A transport device with an undercarriage and interior component module carrier unit that allows preassembled modules to be easily transported and positioned within the aircraft fuselage, featuring movable components for horizontal and vertical adjustment, along with a suspension and support system to facilitate precise placement and minimize repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If interior components are mounted individually in the aircraft, then each component can be precisely positioned, but the mounting process becomes very time-consuming
Solution Approach 1:
The invention divides the aircraft interior into modular components (overhead bins, panels, lighting fixtures, air conditioning units) that are pre-assembled as complete modules outside the aircraft. These modules are then transported and installed as single units using the transport device, eliminating the need to individually position and fasten each component separately within the aircraft.
Solution Approach 2:
The transport device enables preliminary assembly and testing of interior modules to be completed outside the aircraft before final installation. Modules are pre-positioned, pre-tested for functionality (including leak tests for air lines and electrical interface checks), and then transported as complete units to the aircraft, significantly reducing on-site mounting time and complexity.
2Productivity
If components are preassembled outside the aircraft, then assembly and testing can be done more efficiently, but transporting and positioning the modules becomes challenging
Solution Approach 1:
The transport device is designed as a multi-functional system that combines transportation, positioning, and installation functions. The device includes a support structure with movable carriers that can transport modules horizontally and vertically, position them precisely at the aircraft opening, and facilitate their attachment to the aircraft structure. This universal device handles multiple operations that would otherwise require separate equipment and procedures.
Solution Approach 2:
The transport device incorporates movable and adjustable components including carriers that can move along rails, adjustable positioning mechanisms, and flexible support structures. These dynamic elements allow the device to adapt to different module sizes and weights, and to precisely position modules at various locations within the aircraft, simplifying what would otherwise be a complex fixed-positioning task.
3Ease of operation
If modules are transported into the aircraft fuselage, then final assembly is simplified, but precise positioning and tolerance compensation become difficult
Solution Approach 1:
The transport device incorporates adjustable positioning mechanisms that allow operators to fine-tune the location of each module as it is being installed. Movable carriers and adjustable support structures enable precise positioning in multiple directions, allowing for real-time compensation of dimensional tolerances and ensuring accurate alignment with the aircraft structure during the final assembly process.
Solution Approach 2:
The positioning system includes measurement and feedback mechanisms that monitor the location and orientation of modules during transport and installation. This feedback allows operators to make real-time adjustments to achieve precise positioning, ensuring that modules are correctly aligned with aircraft structural features despite variations in manufacturing tolerances of either the modules or the aircraft structure.

AI summary
A transport device for use when mounting interior component modules in an aircraft includes an undercarriage and an interior component module carrier unit. The interior component module carrier unit is supported on the undercarriage and is adapted to be connected to an interior component module, which is preassembled outside of the aircraft, in order to transport the interior component module with the aid of the transport device into a final assembly position in an aircraft fuselage element. At least a part of the interior component module carrier unit is movable relative to the undercarriage such that an interior component module connected to the interior component module carrier unit is movable horizontally and vertically relative to the undercarriage.
