Aircraft Cabin Overhead Storage Compartment Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing overhead storage compartments for aircraft cabins are laborious and time-consuming due to the use of honeycomb sandwich materials, which require extensive manual work and do not allow for the integration of functional elements during the production of the shell and end walls.
Innovation Solution
The use of undirected long fiber reinforced plastic material for the end walls, which can be easily processed and allows for the inclusion of metal inserts and reinforcements during the production process, simplifying the assembly with the shell part through grooves and form-fitting connections, and potentially using composite or sandwich materials for enhanced strength and lightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If honeycomb sandwich material is used for shell part and end walls, then weight is reduced and shear strength is increased, but manufacturing complexity increases and production time extends due to required manual assembly operations
Solution Approach 1:
The patent merges the assembly operations into the pre-production phase by integrating functional elements, fittings, and reinforcements directly into the honeycomb sandwich panels during manufacturing. This combining of separate operations (material production + assembly) eliminates subsequent manual assembly steps, resolving the contradiction between using high-performance honeycomb material and maintaining high productivity.
Solution Approach 2:
The patent applies preliminary action by pre-assembling all functional elements, fittings, and reinforcements into the shell part and end walls during the honeycomb sandwich material production phase. This advance preparation eliminates the need for time-consuming manual assembly operations later, thereby increasing manufacturing speed while maintaining the structural advantages of honeycomb material.
2Strength
If honeycomb sandwich material is used for shell part and end walls, then structural strength is improved, but device complexity increases due to multiple separate assembly steps for fittings and reinforcements
Solution Approach 1:
The patent combines multiple separate assembly operations (installing fittings, reinforcements, functional elements) into a single integrated production process. By merging these operations into the honeycomb sandwich material manufacturing phase, the device complexity is reduced while the structural strength benefits of honeycomb material are preserved.
3Manufacturing precision
If manual assembly operations are used for fitting and mounting, then precision of fitting can be achieved, but production time increases significantly
Solution Approach 1:
The patent applies preliminary action by completing all fitting and mounting operations during the pre-production phase of honeycomb sandwich material manufacturing. This advance completion of assembly operations eliminates time-consuming manual work later while maintaining fitting precision through controlled manufacturing processes.
Solution Approach 2:
The patent replaces manual mechanical assembly operations with automated manufacturing processes during the production of honeycomb sandwich material. This substitution maintains fitting precision through precise manufacturing control while dramatically reducing assembly time by eliminating manual labor.
4Adaptability or versatility
If functional elements are added during assembly step, then adaptability of the structure is improved, but manufacturing complexity and time increase
Solution Approach 1:
The patent merges the integration of functional elements with the material production process. By combining these operations into a single manufacturing phase, the adaptability of the structure is maintained while the manufacturing process is simplified, as all elements are incorporated simultaneously rather than through multiple separate assembly steps.

AI summary
Described and illustrated is a method for manufacturing an overhead storage compartment (1) for an aircraft cabin. The method requires providing a shell part (3) extending between a first end (11) and a second end (13), wherein the shell part (3) has a first edge (17) at the first end (11) and a second edge (19) at the second end (13); providing a first end wall (5) and a second end wall (7); and assembling the shell part (3) and the first and second end walls (5, 7), wherein the first edge (17) is attached to the first end wall (5) and the second edge (19) is attached to the second end wall (7), such that the shell part (3), the first end wall (5) and the second end wall (7) together surround an interior space (15). The object, to provide a simple and fast method for manufacturing an overhead storage compartment (1), wherein possibly little handwork is required, is achieved in that the first end wall (5) and/or the second end wall (7) comprise an undirected long fiber reinforced plastic material.
