Flexible Plastic Film Life Jacket Stowage with Locking Flap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing life jacket stowage devices fail to adequately protect the stored life jackets from external influences and damage, as they lack effective mechanisms to secure the stowage space and ensure easy access for removal.
Innovation Solution
A stowage device with a lock element, first and second closure elements formed by flexible plastic films, and a Velcro fastener unit, which secures the stowage space and allows easy access by folding away the closure elements and lock flap, preventing unwanted penetration and facilitating quick removal of the life jacket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple closure element is used to close the stowage space, then the device complexity is reduced, but the protection against external influences and damage is insufficient
Solution Approach 1:
The closure mechanism is divided into multiple independent components: a first closure element for initial closure, a second closure element for reinforcement, and a lock element for security. Each component performs a specific function, collectively providing robust protection while maintaining reasonable complexity through modular design.
Solution Approach 2:
The closure elements are arranged in a nested configuration where the first closure element is positioned forward, the second closure element is positioned rearward and can rest against the first closure element, and the lock element is arranged behind both closure elements. This nested arrangement maximizes protection within the available space.
2Object-affected harmful factors
If a lock element is added to prevent access into the stowage space, then the protection against external influences is improved, but the device complexity increases
Solution Approach 1:
The lock element is positioned specifically behind the first and second closure elements, creating a localized security barrier at the most vulnerable point (the rearward direction). This targeted approach provides effective access prevention without requiring a complete redesign of the entire closure system.
Solution Approach 2:
Instead of having the lock element face forward to meet approaching objects, the lock element is inverted to face rearward, positioned behind the closure elements. This inverted arrangement effectively blocks access from the rearward direction while allowing the closure elements to function normally from the forward direction.
3Ease of operation
If closure elements are made from flexible material, then the ease of operation is improved, but the protection strength may be reduced
Solution Approach 1:
The solution combines flexible closure elements with a rigid lock element. The flexible first and second closure elements provide ease of operation and sealing, while the rigid lock element positioned behind them provides the necessary structural strength and protection against forced access, creating a hybrid system that achieves both flexibility and strength.

AI summary
The stowing device has a stowing unit (10) which has two closure elements (12) that are provided to delimit a stowing chamber of the stowing unit from an environment (20). A locking element (16) is provided to obstruct a passage to the closure elements all over in the stowing chamber. The locking element is observed in the direction of the stowing chamber from the environment and is arranged behind the closure elements. The locking element is formed as locking flap. The closure elements and the locking element are formed in large portion by a plastic film.
