Overhead Payload Module Stowbin Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft overhead payload modules are heavy, costly, and inefficient in terms of space utilization, with separate mounting and installation requirements that increase installation time and complexity.
Innovation Solution
The overhead payload module integrates a ceiling assembly, aisle floor assembly, and payload assemblies with structurally integrated stowbin modules and aisle support structures, using blade fittings for secure attachment to support rails, enhancing load-carrying capacity and reducing weight and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the module and stowbin support assembly are separately mounted to the same support structure, then both components can be independently installed and maintained, but the support structure requires additional space and the installation time increases
Solution Approach 1:
The patent combines the module and stowbin support assembly into a single integrated structure where the stowbin support assembly is mounted to the module rather than separately to the support structure. This integration eliminates the need for separate mounting operations and reduces installation time while maintaining the functional independence of both components through modular design elements that allow for easy assembly and disassembly.
2Ease of manufacture
If the module and stowbin support assembly are separately mounted, then each component can be optimized independently, but excessive fasteners and components are required
Solution Approach 1:
The integration of the stowbin support assembly to the module creates a unified structure that shares common mounting interfaces and fastening points. This reduces the total number of fasteners required compared to separately mounting both components to the support structure, while still allowing independent optimization of each component's design and manufacturing.
3Reliability
If separate mounting structures are used for the module and stowbin support assembly, then each can be securely attached, but the overall weight increases
Solution Approach 1:
By integrating the stowbin support assembly to the module, the patent eliminates redundant mounting structures and shared load paths. The unified structure uses a single set of mounting interfaces and fasteners to secure both components, reducing the overall weight while maintaining secure attachment through proper structural design and load distribution.

AI summary
In an example, an overhead payload module is described. The overhead payload module comprises a ceiling assembly, an aisle floor assembly, a first payload assembly attached to the ceiling assembly and the aisle floor assembly to form a first side of the overhead payload module, and a second payload assembly attached to the ceiling assembly and the aisle floor assembly to form a second side of the overhead payload module. The first payload assembly comprises a first payload module and a first overhead stowbin module structurally integrated with the first payload module and having a first stowage area configured to receive stowbins. The second payload assembly is positioned opposite the first payload assembly to form an aisle therebetween and comprises a second payload module and a second overhead stowbin module structurally integrated with the second payload module and having a second stowage area configured to receive stowbins.
