Fenestrated Flap Diaper for Stool Isolation
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
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
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
Implementation Method 2
the inner surface can be constructed with conventional absorbent filler material capable of absorbing bodily discharge, i.e., urine and stool
