Safeguarding arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft galleys face challenges in securely storing transport containers during flight, as existing safeguarding arrangements fail to effectively restrict the movability of containers, leading to dynamic loads that can endanger passengers, crew, or aircraft structures.
Innovation Solution
A variable safeguarding arrangement with multiple parts that can be swivelled about a common axis, featuring a coupling member and switching element, allows for adjustable engagement depth to prevent container acceleration, ensuring secure storage and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed safeguarding means is used to secure transport containers, then the container is held securely in the reception, but the reception cannot accommodate containers of varying depths efficiently
Solution Approach 1:
The safeguarding means is designed with dynamic adjustability, allowing the engagement depth to be varied depending on the container size. The holding parts can be positioned at different depths within the reception to accommodate both full-size and half-size trolleys effectively.
Solution Approach 2:
The safeguarding means is divided into multiple holding parts (first holding part and second holding part) that can be independently positioned. This segmentation allows each holding part to engage with different portions of the container, providing secure retention while adapting to various container configurations.
2Reliability
If the safeguarding means engages deeply into the reception to secure containers, then container stability is improved, but the operation complexity increases
Solution Approach 1:
The safeguarding means incorporates a spring element that automatically returns the holding parts to their initial position after container insertion. This self-service mechanism reduces the effort required by service personnel, as the system automatically resets without requiring manual intervention for each operation.
Solution Approach 2:
The switching element provides dynamic control, allowing service personnel to easily transition between locked and unlocked states with minimal effort. The mechanical design of the switching element enables intuitive operation while maintaining secure engagement when activated.
3Device complexity
If a single holding part is used in the safeguarding means, then the device complexity is reduced, but the ability to secure various container sizes is compromised
Solution Approach 1:
The safeguarding means is divided into multiple holding parts (first holding part and second holding part) that can be independently positioned. This segmentation allows each holding part to engage with different portions of the container, providing secure retention while adapting to various container configurations.
Solution Approach 2:
The multiple holding parts are designed to work together as a universal securing system that can accommodate different container types and sizes. The first holding part and second holding part can be positioned at different depths to secure both full-size and half-size trolleys using the same safeguarding means.
4Ease of manufacture
If the safeguarding means is designed with fixed engagement depth, then the manufacturing precision is simplified, but the security against dynamic loads during flight is insufficient
Solution Approach 1:
The safeguarding means is designed with dynamic adjustability, allowing the engagement depth to be varied depending on the container size. The holding parts can be positioned at different depths within the reception to accommodate both full-size and half-size trolleys effectively, ensuring adequate security against dynamic loads during flight.

AI summary
The present disclosure pertains to a safeguarding arrangement (10) for restricting the movability of at least one transport container (17) storable or stored in a reception (16) of a support structure (14). The mentioned transport container (17) may be used for the transport of goods, for example, in an aircraft, and may be stowed in the area of the aircraft's galley as a so-called trolley (18, 19). The safeguarding arrangement (10) has a first safeguarding installation (11) with at least one first safeguarding means (12). The at least one first safeguarding means (12) allows a the supply or the retraction of the at least one transport container (17) into the reception or from the reception, respectively, in its open position via an opening (15). At this the safeguarding means (12) overlaps a clean measure of the opening (15) of the reception (16) at least zonally in a hold position, in which the at least one transport container (17) is held against retraction from the reception (16). Further, the first safeguarding means (12) is formed variably with regard to its engagement depth into the reception (16).
