Self-Inflating Infant Float with Compressible Sponge Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming rings for infants pose safety hazards, such as cervical vertebrae injury and buoyancy imbalance, and are inconvenient to store due to their size and material volume.
Innovation Solution
A self-inflating breaststroke float with a U-shaped structure, featuring a sealed sleeve body with a sponge, an air nozzle, and a vest-like protecting device with adjustable straps, allowing for compact storage and easy inflation for use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foam material is used for the breaststroke float, then stability and integrity during use are improved, but volume occupied during taking and placement increases, making it inconvenient to store and increasing damage probability
Solution Approach 1:
The patent applies parameter changes by transforming the physical state of the float from expanded (during use) to compressed (during storage). The foam material maintains its stability and integrity properties while its volume parameter is dynamically changed through compression for storage and expansion for use, resolving the contradiction between reliability and storage volume.
Solution Approach 2:
The patent implements dynamics by making the float's volume variable rather than fixed. The float transitions between compressed and expanded states, allowing it to adapt its volume based on whether it is being stored or used. This dynamic behavior resolves the contradiction by having small storage volume while maintaining large operational volume for stability.
2Ease of manufacture
If the breaststroke float is designed with fixed structure, then manufacturing simplicity is improved, but adaptability to different infant sizes is reduced
Solution Approach 1:
The patent applies segmentation by dividing the float into modular components including adjustable shoulder straps, detachable protecting devices, and separable connecting straps. These segmented parts can be independently adjusted or removed to accommodate different infant sizes and body types, maintaining manufacturing simplicity while enhancing adaptability.
Solution Approach 2:
The patent implements dynamics through adjustable and detachable components that allow the float's structure to be modified according to different infant sizes. The adjustable shoulder straps and detachable protecting devices enable the same float to adapt to various users without requiring multiple fixed-size models, resolving the contradiction between manufacturing simplicity and adaptability.
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 self-inflating design enables convenient storage and safe, reliable use by compressing the float for transport and expanding for use, addressing safety and storage issues while providing stable support for infants.
Implementation Method 1
The sponge can expand after communicating with outside air to realize self-inflation of the swimming ring
