Aircraft Cargo Deck Section Force Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cargo deck designs for aircraft are complex, heavy, and require elaborate assembly to achieve stability, particularly in absorbing longitudinal forces during aircraft acceleration and braking.
Innovation Solution
A cargo deck design where floor panels and profile elements are firmly connected to form stable deck sections that transmit longitudinal forces to the outer edges, eliminating the need for transverse beams, and using intermediate elements attached to the outer skin to dissipate forces, allowing for simplified assembly and reduced weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transverse beams are provided to absorb longitudinal forces, then stability and force absorption capability are improved, but device complexity and weight increase
Solution Approach 1:
The patent merges the floor panels and profile elements into a unified deck section structure where the profile elements are firmly connected to the floor panels. This integration allows the combined structure to transmit longitudinal forces directly to the outer skin without requiring separate transverse beams, thereby reducing device complexity while maintaining stability.
Solution Approach 2:
The deck sections serve multiple functions: they provide the cargo deck surface, transmit longitudinal forces to the outer skin, and act as structural components that eliminate the need for separate force-absorption elements. This multi-functionality reduces overall device complexity while maintaining reliability.
2Force
If transverse beams are provided to absorb longitudinal forces, then force absorption capability is improved, but weight increases
Solution Approach 1:
By combining the floor panels and profile elements into integrated deck sections, the structure utilizes the existing components to transmit longitudinal forces directly to the outer skin, eliminating the need for additional heavy transverse beams while maintaining force absorption capability.
Solution Approach 2:
The invention extracts and eliminates the transverse beams from the cargo deck structure, relying instead on the firmly connected floor panels and profile elements to transmit longitudinal forces directly to the outer skin, thereby reducing weight while maintaining force absorption capability.
3Reliability
If elaborate assembly is used to achieve stability, then stability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The integration of floor panels and profile elements into unified deck sections creates a structure that inherently transmits forces effectively, reducing the need for elaborate assembly procedures while maintaining stability.

AI summary
In an aircraft there is customarily provided, for receiving a load in the cargo compartment, a cargo deck that comprises a plurality of ball mats, floor panels or similar flat floor elements. Also provided are a plurality of roller conveyors or similar profile elements mounted in the long direction of the aircraft to accommodate transport rollers, PDUs, latches or similar functional units for moving and fixing the load on the cargo deck. To simplify the arrangement and the assembly it is proposed in the present invention that the floor elements at least in sections be firmly connected to the profile elements to form a deck section that extends across the entire width of the cargo compartment, in such a way that longitudinal forces imposed on the deck section, in particular imposed by the load, oriented in the direction of an aircraft long axis and acting as shear forces in the surface direction of the cargo deck, can be transmitted to outer edges of the deck section and can be dissipated from the outer edges to an outer skin of the aircraft that is reinforced by ribs.
