Buoyancy Garment Movable Arm Circuits for Child Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buoyancy garments for children restrict arm movement due to buoyancy materials, making it difficult for them to stretch their arms flexibly and limiting their mobility and practicality.
Innovation Solution
A comfortable buoyancy garment design featuring movable arm circles, a cardigan structure with zippers and velcro, and semi-annular buoyant members to enhance flexibility and comfort, allowing for easy movement without burdening the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If buoyancy cotton is used to provide safety and buoyancy, then safety and buoyancy performance are improved, but arm flexibility and movement freedom deteriorate
Solution Approach 1:
The arm circle is divided into multiple movable units (first arm circle units and second arm circle units) that can move independently relative to each other and to the main body, allowing the buoyancy structure to be segmented into flexible segments that maintain safety while enabling arm movement
Solution Approach 2:
The arm circle units are designed to be movable rather than fixed, allowing dynamic adjustment of the buoyancy structure to accommodate arm movement while maintaining safety. The movable connection enables the structure to adapt to different arm positions
2Reliability
If buoyancy cotton is used to ensure safety, then safety is improved, but movement freedom and practicability worsen
Solution Approach 1:
The buoyancy structure is segmented into movable arm circle units that can independently adjust their position, allowing the garment to adapt to various movement requirements while maintaining safety through the distributed buoyancy units
Solution Approach 2:
The movable arm circle units allow changes in the spatial parameters and configuration of the buoyancy structure to accommodate different movement states, maintaining safety while providing movement freedom
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 design allows for convenient and flexible arm movement, improving the comfort and practicality of the buoyancy garment, reducing the burden on the user's activities and enhancing safety performance.
Implementation Method 1
the side surface of the fixing piece close to the zipper is provided with a first velcro, the second connecting edge is provided with a second velcro, and the first velcro is detachably attached to the second velcro
Implementation Method 2
the main body has a front accommodating cavity, a left-rear accommodating cavity and a right-rear accommodating cavity, the front accommodating cavity, the left-rear accommodating cavity, and the right-rear accommodating cavity all contain at least one of a first buoyancy member

AI summary
A comfortable buoyancy garment includes a main body, a first arm circle, a second arm circle. The main body has a first connecting portion and a second connecting portion at two armpits thereof respectively. The first arm circle includes at least two first arm circle units, movably connected with the first connecting portion, any two adjacent of the first arm circle units are movably connected. The second arm circle includes at least two second arm circle units, movably connected with the second connecting portion, any two adjacent of the second arm circle units are movably connected. When a user wears the above comfortable buoyancy garment, the first arm circle units and the second arm circle units are convenient to wear and flexible to move, will not cause a burden on the user's activities, so as to enhance the comfort of wearing the buoyancy garment and reduce the burden when wearing them to move.
