Fluid-Like Infant Positioner Layers for Therapeutic Premature Support

Solution Overview

Problem

Existing positioners for premature infants do not provide additional benefits beyond supporting desired orientations, failing to mimic the in utero environment and offer therapeutic positioning.

Innovation Solution

A positioner comprising a base, intermediate, and outer chamber filled with materials to mimic the uterus, allowing lateral movement and reducing friction, thereby replicating the conditions within the womb.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a positioner uses a fixed rigid structure to support infants in desired orientations, then positioning stability is improved, but the ability to mimic the in utero environment and provide therapeutic positioning is worsened

Engineering Contradiction:

Improvepositioning stabilityVSAvoidability to mimic in utero environment

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The positioner is divided into multiple chambers (outer chamber, intermediate chamber, inner chamber) that can move independently relative to each other. This segmentation allows each layer to provide different functions: the outer chamber provides stable support, while the inner chamber mimics the fluid-like movement of amniotic fluid, thus resolving the contradiction between stability and adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The positioner incorporates dynamic elements that allow movement between chambers. The intermediate chamber can slide laterally relative to the base chamber, and the outer chamber can move relative to the intermediate chamber, creating a dynamic system that adapts to infant movement while maintaining overall positioning stability.

Inventive Principle:

Principle #15Dynamics

2Device complexity

If a positioner uses a single-layer structure, then device complexity is reduced, but the ability to provide attenuated conformational positioning and reduce friction is worsened

Engineering Contradiction:

Improvestructure complexityVSAvoidconformational positioning capability

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The positioner is divided into multiple chambers (outer chamber, intermediate chamber, inner chamber) that can move independently relative to each other. This segmentation allows each layer to provide different functions: the outer chamber provides stable support, while the inner chamber mimics the fluid-like movement of amniotic fluid, thus resolving the contradiction between stability and adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The intermediate chamber acts as a mediator between the outer and inner chambers. It contains a lubricant that reduces friction between layers, enabling the inner chamber to move smoothly relative to the outer chamber, thus providing the desired conformational positioning capability while maintaining a manageable structural complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Stability of the object's composition

If a positioner uses high-friction materials to prevent sliding, then positioning control is improved, but the ability to mimic amniotic fluid movement and enable proprioceptive development is worsened

Engineering Contradiction:

Improvepositioning controlVSAvoidproprioceptive development capability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

Different chambers use different friction characteristics: the outer chamber uses higher friction materials to prevent excessive sliding and maintain positioning control, while the inner chamber uses low-friction materials to allow free movement and mimic amniotic fluid, enabling proprioceptive development. This local differentiation resolves the contradiction between control and adaptability.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The intermediate chamber acts as a mediator between the outer and inner chambers. It contains a lubricant that reduces friction between layers, enabling the inner chamber to move smoothly relative to the outer chamber, thus providing the desired conformational positioning capability while maintaining a manageable structural complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

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 positioner provides attenuated conformational positioning, enabling proprioceptive development and reducing friction for premature infants, mimicking the in utero environment.

Implementation Method 1

The intermediate chamber and its fill may define a middle layer of the positioner. The fill of the intermediate chamber may comprise a lubricant that will enable the base chamber and the outer chamber to slide relative to one another.

AI summary

A positioner includes a bottom layer, an intermediate element, and a top layer. The top layer can move laterally over the bottom layer, while the intermediate element limits the extent to which the top layer can move over the bottom layer. The top layer, the bottom layer, and the ability of the top layer to move across the bottom layer may impart the positioner with characteristics that mimic a human uterus, enabling the positioner to be used to support premature infants. Methods of using the positioner are also disclosed.
