Spring-Loaded Leg Rest Housing for Accessible Life Jacket Stowage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passenger seat designs that accommodate life jackets either limit storage space or make the jacket difficult to access, particularly when stored under the seat or in seats with leg rests.
Innovation Solution
A pivoting leg rest with a housing device that securely stores the life jacket, featuring two housing halves connected by a spring device, allowing for easy access and storage optimization by pivoting from a closed to an open position, and vice versa, with a locking mechanism for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the life jacket is stored under the seat cushion or below the armrest, then storage space is provided, but access to the life jacket is difficult or storage space for other components is limited
Solution Approach 1:
The housing is divided into two separable halves that can pivot relative to each other, creating an accessible opening while maintaining a compact closed structure. This segmentation allows the life jacket to be easily accessed by opening the housing without requiring complex mechanisms.
Solution Approach 2:
The housing transitions from a static closed structure to a dynamic open structure through pivoting movement. The spring device enables automatic opening and closing actions, making the housing adaptable between storage mode (closed) and access mode (open).
2Quantity of substance
If the life jacket is placed below the armrest, then storage is provided, but the life jacket is comparatively difficult to access
Solution Approach 1:
The housing is divided into two separable halves that can pivot relative to each other, creating an accessible opening while maintaining a compact closed structure. This segmentation allows the life jacket to be easily accessed by opening the housing without requiring complex mechanisms.
Solution Approach 2:
The spring device automatically opens the housing when the life jacket needs to be accessed, eliminating the need for manual manipulation of latches or locks. The housing serves itself by using the spring's stored energy to perform the opening action.
3Quantity of substance
If the life jacket is stored under the seat cushion of a passenger seat with a leg rest, then storage is provided, but the life jacket is not accessible
Solution Approach 1:
The housing transitions from a static closed structure to a dynamic open structure through pivoting movement. The spring device enables automatic opening and closing actions, making the housing adaptable between storage mode (closed) and access mode (open).
Solution Approach 2:
The spring device automatically opens the housing when the life jacket needs to be accessed, eliminating the need for manual manipulation of latches or locks. The housing serves itself by using the spring's stored energy to perform the opening action.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy access to the life jacket while optimizing storage space, ensuring the life jacket is securely protected and reducing the risk of tripping hazards during emergency situations.
Implementation Method 1
the device has a spring device, wherein the first housing half is subjected to a force relative to the second housing half by a spring force of the spring device, such that the first housing half can be moved from an open position relative to the second housing half towards a closed position relative to the second housing half
