Tiltable Back Float Structure for Vertical Swim Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming aids that are worn on the back do not provide sufficient safety for small children and are unsuitable for teaching basic swimming skills.
Innovation Solution
A swimming aid with a tiltable back float that allows a limited tilting angle of up to 45°, promoting a more vertical posture in the water, enhancing safety and encouraging basic swimming movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the back float is fixed rigidly to the supporting structure, then the structure is simple and stable, but the user cannot achieve a vertical posture and swimming skills cannot be developed
Solution Approach 1:
The back float is connected to the supporting structure through a hinge mechanism that allows controlled tilting movement. This dynamic connection enables the float to adjust its angle relative to the supporting structure, allowing users to achieve a vertical posture in water while maintaining structural stability through the hinge's controlled motion capability
2Ease of operation
If the back float is allowed to tilt freely, then the user can achieve vertical posture, but the tilting angle cannot be controlled and safety is compromised
Solution Approach 1:
The hinge mechanism incorporates a stop element that limits the tilting angle of the back float to a maximum of 45 degrees relative to the supporting structure. This parameter control ensures the float can tilt sufficiently to enable vertical posture achievement while preventing excessive tilting that would compromise water safety
3Reliability
If the float is positioned horizontally on the back, then the swimmer is held in horizontal position for learning, but the head cannot be kept above water and safety is reduced
Solution Approach 1:
The hinge mechanism enables the back float to tilt upward relative to the supporting structure, allowing the float to position itself at an angle that promotes vertical body posture. This dynamic adjustment enables the user's head to remain above water while maintaining safety through the controlled 45-degree angle limitation

Function Achieved in This Case
The tiltable back float design improves water safety and facilitates the development of swimming skills by maintaining the head above water and encouraging forward movement.
Implementation Method 1
a swimming aid (1) with a supporting structure (2) provided with a float (3), in particular a back float (3), which is to be worn on the back during use

AI summary
Swimming aid (1) being configured to increase a user's buoyancy in the water. The swimming aid has a supporting structure (2) with a back float (3). The supporting structure is designed to secure the swimming aid to a user's upper body. The back float is tiltable - seen in use - about a transverse axis connected to the supporting structure. The tilting movement of the back float to the supporting structure enables the user to obtain an inclined, more vertical posture in the water, which will improve the user's ability to keep their head above the surface of the water and also intuitively encourages the user to stretch out their hands to make a supportive movement with the hands in the water. Thus, the swimming aid increases water safety and at the same time promotes swimming skills.
