Aircraft Life Vest Packaging Unit with Integrated Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing life vest devices for aircraft seats are cumbersome to replace and require additional sealing, which can disrupt aircraft operations and increase maintenance time.
Innovation Solution
A life vest device with a packaging unit that includes a fixation unit for secure attachment to the aircraft seat, allowing for simple and rapid replacement without separate sealing, featuring an integrated opening mechanism that is tear-proof and can be actuated to irreversibly open the packaging unit, ensuring safe and efficient handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate sealing mechanism is used for the life vest packaging, then the sealing reliability is improved, but the device complexity and maintenance time increase
Solution Approach 1:
The patent combines the sealing function with the packaging unit itself by creating an integrated seal that is part of the packaging structure. The seal is formed by the packaging unit's design where the cover and base portions create a sealed environment without requiring separate sealing mechanisms, thus reducing device complexity while maintaining sealing reliability.
Solution Approach 2:
The packaging unit serves multiple functions: it protects the life vest, provides sealing, and enables easy replacement. The integrated design of the packaging unit with built-in sealing capability allows it to perform both protective and sealing functions simultaneously, eliminating the need for separate sealing components.
2Reliability
If a complex opening mechanism is used for the packaging unit, then the sealing security is improved, but the ease of operation deteriorates
Solution Approach 1:
The packaging unit is divided into separate components: a cover portion and a base portion that can be easily separated. The opening mechanism uses a simple pull strap that detaches from the seal, allowing the cover to be removed from the base. This segmentation provides secure sealing when closed while enabling easy opening when needed.
Solution Approach 2:
The seal is designed as a single-use component that is discarded after opening. The pull strap and seal mechanism are simple, inexpensive elements that are destroyed during the opening process, providing secure sealing during storage while allowing rapid, tool-free opening when emergency equipment is needed.
3Reliability
If additional sealing components are added to the life vest device, then the sealing reliability is improved, but the weight and space requirements increase
Solution Approach 1:
The sealing function is merged into the packaging unit structure itself. The packaging unit's cover and base portions form an integrated seal without requiring additional sealing components, thereby maintaining sealing reliability while minimizing weight and space.
4Reliability
If the life vest device requires separate sealing and replacement procedures, then the safety is improved, but the productivity and replacement speed decrease
Solution Approach 1:
The device is segmented into modular components: the life vest unit, the packaging unit with integrated seal, and the opening mechanism. This segmentation allows the entire packaged unit to be replaced as a single module, maintaining safety through secure sealing while enabling rapid replacement by simply removing the damaged packaging unit and installing a new one without separate sealing procedures.

AI summary
The invention relates to a life vest device (10a; 10b; 10c; 10d), in particular for a fixation on at least one aircraft seat (12a), with at least one life vest unit (30a; 30b; 30c; 30d), with at least one packaging unit (32a; 32b; 32c; 32d) for an, in particular sealed, accommodation of the at least one life vest unit (30a; 30b; 30c; 30d) and with at least one opening unit (52a; 52b; 52c; 52d) for an opening of the at least one packaging unit (32a; 32b; 32c; 32d). It is proposed that the at least one opening unit (52a; 52b; 52c; 52d) is functionally connected with the at least one life vest unit (30a; 30b; 30c; 30d) and that the at least one packaging unit (32a; 32b; 32c; 32d) comprises at least one fixation unit (38a; 38b; 38c, 108c; 38d) for a fixation on an aircraft seat (12a).
