Solution Overview

Problem

Breast prostheses often lack comfort due to direct contact with the skin, leading to increased perspiration and discomfort, and are difficult to clean while maintaining durability and abrasion resistance.

Innovation Solution

A breast prosthesis with a substrate partially or fully flocked with parallel fibers fixed by an adhesive, using an electrostatic field for alignment and application, providing ventilation and ease of cleaning while maintaining a soft feel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the back of the breast prosthesis is made of smooth material for ease of cleaning, then cleaning is simplified, but the wearing comfort and soft feel are reduced

Engineering Contradiction:
Improveease of cleaningVSAvoidwearing comfort
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention applies different surface qualities to different functional requirements: the flocking provides a soft, velvety surface for comfort where it contacts the breast, while the smooth substrate areas allow for easy cleaning. This local differentiation resolves the contradiction between comfort and ease of cleaning.

Inventive Principle:
Principle #3Local quality

2Strength

If the back of the breast prosthesis is made of smooth material for durability and abrasion resistance, then mechanical durability is improved, but the pleasant soft feel is reduced

Engineering Contradiction:
Improvemechanical durabilityVSAvoidpleasant feel
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The substrate provides a durable, abrasion-resistant base layer for mechanical strength, while the flocking layer provides the soft, pleasant feel. This local differentiation of material properties resolves the contradiction between durability and pleasant feel.

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If the back of the breast prosthesis has a pile fabric for soft feel and padding, then wearing comfort is improved, but perspiration increases

Engineering Contradiction:
Improvewearing comfortVSAvoidperspiration
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The flocking structure creates a porous, air-permeable layer that allows ventilation between the prosthesis and the breast, reducing perspiration while maintaining the soft feel and comfort associated with pile fabrics.

Inventive Principle:
Principle #31Porous materials

4Ease of operation

If mechanical cleaning processes are used to maintain hygiene, then cleaning effectiveness is improved, but the feel and comfort of the back are impaired

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidfeel and comfort
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The flocking creates a resilient, three-dimensional surface that can withstand mechanical cleaning processes without losing its soft feel. The flexible fiber structure allows the surface to recover its shape after cleaning, maintaining comfort while enabling effective hygiene maintenance.

Inventive Principle:
Principle #14Spheroidality (Curvature)
