Solution Overview

Problem

Current diaper designs fail to prevent stool from soiling a user's genital area, particularly posing risks during post-operative situations and leading to infections and complications for male infants and adults with incontinence issues.

Innovation Solution

A protective diapering system featuring a fenestrated flap between the anterior and posterior flaps, configured in an hour-glass shape with a waterproof membrane and absorbent material, separates the penis from stool by creating distinct compartments for urine and stool, preventing migration and infection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If conventional absorbent diaper material is used to maximize urine absorption, then urine absorption capability is improved, but stool migration to genital area cannot be prevented

Engineering Contradiction:
Improveurine absorptionVSAvoidstool soiling of genitalia
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The diaper is divided into distinct functional zones: a front body portion with high absorbency for urine, a rear body portion for stool containment, and a crotch portion with a barrier layer that segments the flow paths of urine and stool to prevent stool migration to the genital area

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the diaper are assigned different material properties and functions: the front body uses highly absorbent material for urine, the rear body uses containment-oriented material for stool, and the crotch barrier uses impermeable material specifically to block stool while allowing urine management

Inventive Principle:
Principle #3Local quality

2Reliability

If surgical dressings are placed on the penis to control bleeding and prevent infection, then post-operative care is improved, but early rinsing or removal is necessary if stool soiling occurs

Engineering Contradiction:
Improvepost-operative protectionVSAvoiddressing maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The barrier layer in the crotch portion acts as an intermediary between stool and the surgical dressing on the penis, blocking stool migration while allowing the dressing to remain in place without requiring early removal or rinsing

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If a barrier is introduced to prevent stool migration to genital area, then genital protection is improved, but device complexity increases

Engineering Contradiction:
Improvestool contact with genitaliaVSAvoiddiaper structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The barrier function is merged into the existing diaper structure by incorporating a barrier layer within the crotch portion, combining stool blocking with urine absorption and general containment functions in a single integrated design

Inventive Principle:
Principle #5Merging (Combining)

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

Effectively prevents stool from reaching the genital area, reducing the risk of infection and inflammation, and maintaining the integrity of surgical dressings, enhancing hygiene and safety for users.

Implementation Method 1

the crotch portion can be constructed with a barrier layer capable of blocking stool migration

Methodology Applied
Scientific EffectWaterproof barrier: Hydrophobe

Implementation Method 2

the inner surface can be constructed with conventional absorbent filler material capable of absorbing bodily discharge, i.e., urine and stool

Methodology Applied
Scientific EffectAbsorption: Absorption (physical)
