Aircraft Cargo Unit Transport Cover with Biasing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lower deck catering systems for aircraft face challenges in maintaining the integrity and security of cargo units during transport, as they lack effective mechanisms to prevent contamination and unauthorized access to the interior, especially when not connected to a transport arrangement.
Innovation Solution
A cargo unit with a transport cover that can only be opened after engagement with a transport arrangement, featuring a translational part and a vertical part that move between closed and open positions, ensuring the interior remains sealed until in use, and utilizing a biasing structure to automatically close the cover when disconnected, eliminating the need for external power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transport opening is left open for easy access to the storage rack arrangement, then the ease of operation is improved, but the security and contamination prevention deteriorate
Solution Approach 1:
The transport cover is designed as a movable component that transitions between closed and open positions dynamically. It is closed during transport and storage to prevent contamination, and opens automatically when the cargo unit engages with the transport arrangement, providing access only when needed and in a controlled manner.
Solution Approach 2:
The cover is pre-positioned in the closed state during transport and storage phases, proactively preventing contamination before it can occur. The system is designed so that the cover opens automatically upon engagement with the transport arrangement, eliminating the need for manual intervention and ensuring security is maintained until the moment access is required.
2Object-affected harmful factors
If a secure closed system is used to prevent contamination, then the security is improved, but the ease of operation deteriorates
Solution Approach 1:
The transport cover operates automatically based on the engagement state of the cargo unit. When the cargo unit is engaged with the transport arrangement, the cover opens itself without requiring manual operation. When disengaged, it automatically closes to secure the interior. This self-service mechanism eliminates the need for separate manual opening and closing operations.
Solution Approach 2:
The cover transitions dynamically between closed and open states based on the operational requirements. The system uses the engagement action itself to trigger the opening, and the disengagement action to trigger the closing, making the operation as easy as connecting or disconnecting the cargo unit from the transport arrangement.
3Ease of operation
If manual opening and closing of the transport cover is required, then the ease of operation is improved, but the loss of time increases
Solution Approach 1:
The transport cover opens and closes automatically based on the engagement status of the cargo unit with the transport arrangement. No manual opening or closing operations are required - the system serves itself by using the engagement and disengagement actions to trigger the cover movements, eliminating time-consuming manual interventions.
Solution Approach 2:
The cover is pre-positioned in the closed state during transport phases, eliminating the need for subsequent opening operations during transport. It opens automatically only when engagement with the transport arrangement occurs, and closes automatically upon disengagement, streamlining the entire operational sequence.
4Ease of operation
If the transport cover remains open during transport, then the ease of operation is improved, but the reliability deteriorates
Solution Approach 1:
The transport cover dynamically adjusts its position based on the operational state. During transport and storage phases, it maintains a closed position to preserve the integrity of the cargo unit interior. When the cargo unit engages with the transport arrangement, it automatically opens to provide access. This dynamic behavior ensures reliability is maintained during transport while ease of operation is provided when needed.
Solution Approach 2:
The cover is pre-positioned in the closed state during transport phases, proactively protecting the interior from contamination and maintaining reliability before any access is required. The system is designed so that the cover opens automatically only when engagement with the transport arrangement occurs, ensuring the interior remains sealed during all transport operations.

AI summary
A cargo unit for storage in a cargo hold of an aircraft including a housing and a storage rack arrangement, the housing enclosing the storage rack arrangement and including a transport opening. The cargo unit is connectable to a transport arrangement operable for removing objects from the storage rack arrangement and placing objects in the storage rack arrangement through the transport opening when the cargo unit is arranged in an operating position. The cargo unit includes a transport cover movable between a closed position where the transport cover closes the transport opening and an opened position where the transport opening is not covered by the transport cover. The transport cover is adapted to be only movable from its closed position to its opened position after engagement with a transport arrangement. A lower deck catering system including a cargo unit and a transport arrangement is described.
