Life Jacket Vest With Unattached Lining Sleeves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flotation devices for children, such as life jackets and arm bands, are either uncomfortable, restrictive, or lack sun protection, and fail to keep an incapacitated child's head out of the water.
Innovation Solution
A life jacket vest with integrated sleeves and a neck portion made of ultraviolet-blocking fabric, where the sleeves are not attached to the life jacket member, allowing for greater mobility and sun protection without restricting arm or neck movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sleeves are attached to a life jacket to provide sun protection, then sun protection is improved, but comfort and range of motion deteriorate
Solution Approach 1:
The life jacket is divided into separate functional components: the flotation device (life jacket member) and the sun protection layer (lining with sleeves and neck portion). These components are attached at strategic locations rather than being fully integrated, allowing the sun protection layer to provide coverage without restricting movement. The lining is attached to the life jacket member at the front, rear, and sides, but the sleeve armholes remain unattached to allow full arm mobility.
Solution Approach 2:
The lining with sleeves is inserted into and extends through the arm apertures of the life jacket member, creating a nested structure where the sun protection layer fits within the flotation device's arm openings. This nesting allows the lining to provide sun protection while the life jacket member maintains its flotation function and arm mobility.
2Reliability
If a life jacket is made restrictive to keep an incapacitated child's head out of water, then safety is improved, but comfort deteriorates
Solution Approach 1:
The device separates the safety function (life jacket member providing flotation and head support) from the comfort function (lining providing sun protection and unrestricted movement). The lining is attached at the front, rear, and sides but leaves the arm openings unattached, allowing children to move their arms freely while the life jacket member maintains its safety function.
Solution Approach 2:
The lining provides sun protection specifically in areas where it is needed (arms and neck) without affecting the overall mobility of the child. The unattached sleeve armholes allow full range of motion in the arms, while the attached portions provide sun protection. This local application of sun protection maintains comfort while providing safety.
3Ease of operation
If arm bands are used instead of life jackets, then comfort is improved, but protection capability deteriorates
Solution Approach 1:
The device merges the comfort of arm bands with the protection capability of life jackets. The lining with sleeves provides a comfortable, rash guard-like fit that children are willing to wear, while the life jacket member attached to it provides the necessary flotation and head support. The combination creates a device that is both comfortable and protective.
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
The life jacket vest provides comfortable flotation, sun protection, and maintains the head out of the water, even for an incapacitated child, while allowing for unrestricted movement.
Implementation Method 1
The lining is also preferably made of ultraviolet-blocking fabric
Implementation Method 2
life jacket member is a life jacket as known and understood in the art

AI summary
A life jacket vest including a life jacket member having a pair of arm openings and a lining having a pair of sleeve members and a perimeter. The lining is positioned in mating relationship with at least a portion of the life jacket member and is attached along at least a portion of the perimeter of the life jacket member. The sleeve members are received and extend through the openings of the life jacket member and are not attached to the life jacket member. The life jacket member may include a fastener member and a size adjustment member. The lining may include a neck portion and a collar portion. By attaching the lining to the life jacket member in places other than the arm openings, the present life jacket vest allows for a greater range of motion and less constraints in the arm openings of the life jacket member.
