Solution Overview

Problem

Existing lying floats for infants lack support for the legs and feet, necessitating the use of a bath towel on the ground to maintain sanitation and hygiene.

Innovation Solution

A float with a retractable foot rest, comprising a lying float body, a supporting element, a protecting assembly, and a foot rest cushion that can be expanded to support the legs and feet, and then retracted for storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the supporting cushion is kept short to maintain simplicity, then the float structure remains simple, but the legs and feet of infants cannot be supported requiring additional bath towels

Engineering Contradiction:

Improvesanitation supportVSAvoidfloat structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The foot rest cushion is designed to be retractable and expandable. When needed for sanitation, it can be pulled out from the supporting element; when not needed, it can be retracted to maintain a compact structure. This dynamic adjustment resolves the contradiction between providing leg support and maintaining structural simplicity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The foot rest cushion is stored within or attached to the supporting element structure. When retracted, the cushion is nested within the float body or folded against the supporting element, keeping the overall structure compact while still providing the capability to extend when needed for sanitation purposes.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Volume of moving object

If the foot rest cushion is made retractable to save space, then storage efficiency improves, but the mechanism for retracting and expanding becomes more complex

Engineering Contradiction:

Improvestorage spaceVSAvoidretracting mechanism

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The foot rest cushion utilizes flexible fabric or thin material that can be easily folded, rolled, or compressed. This flexibility allows the cushion to be retracted into a compact form without requiring complex mechanical structures, achieving space savings while keeping the retracting mechanism simple.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

Instead of using complex mechanical retracting mechanisms, the design relies on simple fastening elements like Velcro, zippers, or elastic bands to secure the cushion in extended or retracted positions. This substitutes complex mechanics with simpler fastening systems, reducing overall device complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The present invention proposes a float with a retractable foot rest, comprising a lying float body, a supporting element, a protecting assembly and a foot rest cushion. The supporting element and the protecting assembly are installed in a lying float splicing body; the foot rest cushion that can be retracted or expanded is installed at the lower end of the supporting element; and the foot rest cushion is connected with the supporting element. When the float is worn, the foot rest cushion can be expanded to replace an additional bath towel that needs to be placed on the ground to prevent dirt. After wearing, the foot rest cushion can be retracted below the supporting element, or as required, the floating body is spliced on the lying float body, and the foot rest cushion is connected with the floating body.
