Buoyant Elastic Foam Abdominal Wrap for Swimming Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming training methods and tools fail to effectively address the fear of drowning due to breathing difficulties in water and do not efficiently guide beginners to master swimming in a short time, particularly for those with abnormal postures and varying centers of gravity and buoyancy.
Innovation Solution
A training method involving voluntary contraction of lateral abdominal muscles to perform drawing-in, combined with a training tool made of elastic foam that provides buoyant force, stretchability, and flexibility, which helps maintain a drawing-in state and adjusts the center of gravity and buoyancy to facilitate breathing and streamline swimming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If buoyant materials are attached to the body with a string in front crawl, then buoyant force is provided, but breathing becomes difficult and head sinks
Solution Approach 1:
The patent introduces a floating tool as an intermediary device that provides buoyant force without requiring string attachment to the body. The floating tool acts as a mediator between the swimmer and water, offering buoyancy while allowing free movement of hands and face for breathing.
Solution Approach 2:
The patent extracts the buoyant function from the body-attached string configuration and separates it into an independent floating tool. This extraction allows the buoyant force to be provided externally without constraining the swimmer's ability to breathe or move freely.
2Force
If floating tool is used to practice swimming, then buoyant support is provided, but free movement of hands is restricted
Solution Approach 1:
The floating tool serves as an intermediary that provides buoyant support without creating physical constraints on the swimmer's limbs. It supports the body in water while allowing hands and arms to move freely for swimming strokes.
3Stability of the object's composition
If buoyant material is attached to lower-back part, then center of buoyancy is adjusted, but comfort is reduced and underwater posture is compromised
Solution Approach 1:
The floating tool acts as an intermediary device that adjusts the center of buoyancy without requiring direct attachment to the lower-back part of the body. This maintains comfort and allows the swimmer to achieve preferable underwater posture while still benefiting from adjusted buoyancy.
4Force
If novice receives rotational force from buoyant force and gravity, then pelvis rotates, but streamline posture is compromised
Solution Approach 1:
The floating tool serves as an intermediary that provides controlled buoyant force to adjust the center of buoyancy position. This controlled approach prevents unwanted pelvic rotation and helps maintain streamline posture during swimming by balancing rotational forces from buoyancy and gravity.

AI summary
A training method includes: a step of contracting a lateral abdominal muscle including a transverse abdominal muscle to pull in an abdominal periphery voluntarily by a trainee; a step of covering the abdominal periphery pulled in voluntarily by the trainee from an upper portion of a pelvis to a bottom of a tenth rib by tightly wrapping while stretching a training tool (6) in a longitudinal shape made of elastic foam having buoyant force, stretchability and flexibility; and a step of carrying out training while maintaining a state where the abdominal periphery is pulled in by shrinking force of the training tool (6).
