Solution Overview

Problem

Current methods for replicating a nursing mother's nipple, such as impression-molding and 3D printing, fail to accurately capture the nipple in an active state of lactation, leading to nipple confusion in babies and safety concerns with used materials.

Innovation Solution

A 3D printing process that converts a breast into an active lactation state, captures precise 3D image data, and prints an elastomeric artificial nipple structure that closely resembles the natural nipple, including surface texturing, for use as a substitute in baby bottles or pacifiers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If impression-molding is used to replicate a mother's nipple, then a custom nipple can be made, but the process physically distorts the nipple area and cannot capture the active lactation state

Engineering Contradiction:
Improvenipple replication accuracyVSAvoidnipple area distortion
Core Design Contradiction:
Manufacturing precisionVSShape

Solution Approach 1:

The patent uses 3D scanning technology to create a digital copy of the mother's nipple in its natural active state, avoiding the physical distortion caused by traditional impression-molding. The digital model captures the nipple's true geometry and surface characteristics without requiring physical contact that would alter its shape.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical impression-molding process with a non-contact 3D scanning system. Instead of using physical molds that distort the nipple area, the system uses optical or electromagnetic fields to capture the nipple's geometry, eliminating mechanical deformation while maintaining replication accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If conventional 3D printing is used to make artificial nipples, then manufacturing is simplified, but the nipple does not accurately resemble the natural nipple in active lactation state

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidnipple resemblance accuracy
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent performs preliminary 3D scanning and digital modeling of the mother's natural nipple in its active lactation state before the actual manufacturing process. This preliminary digital capture ensures that all geometric and surface characteristics are recorded accurately, allowing the subsequent 3D printing to reproduce the natural nipple with high fidelity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses advanced 3D printing parameters and material properties to replicate the natural nipple's surface texture, color, and geometric features. By carefully controlling printing parameters such as layer thickness, material composition, and surface finishing, the artificial nipple achieves accuracy comparable to the natural structure while maintaining manufacturing simplicity.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If resins are used in casting custom nipples from breast impressions, then the nipple can be replicated, but the resins raise safety concerns when used with baby products

Engineering Contradiction:
Improvenipple replicationVSAvoidresin safety
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameters by using food-grade or medical-grade polymers instead of conventional casting resins. These alternative materials maintain the necessary replication precision while eliminating safety concerns related to chemical composition, making them safe for contact with infants during breastfeeding.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite material structures that combine multiple polymers with desirable properties - including safety, flexibility, and visual realism. The composite construction allows for precise nipple replication while using only safe, baby-appropriate materials that eliminate toxicity concerns associated with traditional resins.

Inventive Principle:
Principle #40Composite materials

4Device complexity

If the breast is not in active state of lactation during imaging, then the imaging process is simpler, but the artificial nipple cannot accurately represent the natural state presented to the infant

Engineering Contradiction:
Improveimaging process complexityVSAvoidnipple state accuracy
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent requires the mother to be in the active lactation state during the preliminary 3D scanning process, capturing the nipple's true appearance as presented to the infant. This preliminary action in the correct physiological state ensures that the digital model accurately represents the functional form the baby experiences during feeding.

Inventive Principle:
Principle #10Preliminary action

Applied Scientific Principles

AI summary

An artificial nipple is formed of an elastomeric polymer by use of 3D printing after imaging of a mother's breast in an active state of lactation. The artificial nipple used as an attachment to a baby bottle or as the nipple component of a pacifier. Use of an artificial nipple formed in this manner mitigates a problem with nipple confusion, as may otherwise manifest in newborn offspring.
