Diaper Collection Pouch Structure for Fecal Skin Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diapers pose challenges in managing fecal matter, leading to skin irritation and messy changes, especially for adult patients with conditions like incontinence or severe diarrhea, due to prolonged skin contact and lack of a convenient collection system.
Innovation Solution
A diaper with a collection pouch that includes a backing layer, an absorbent core with a cut line forming an opening for fecal matter to enter a pouch, and a peripheral border structure surrounding the core and backing layer, allowing fecal matter to be directed away from the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional diaper structure is used, then the diaper can absorb urine, but fecal matter contacts the skin causing irritation and messy changes
Solution Approach 1:
The diaper is segmented into distinct functional zones: a collection pouch for fecal matter, an absorbent core for urine, and a barrier layer. This segmentation separates waste collection from skin contact areas, preventing fecal matter irritation while maintaining a manageable overall structure.
Solution Approach 2:
The collection pouch is extracted as a separate, removable component from the main diaper body. This allows fecal matter to be contained and removed independently from the absorbent core, reducing mess during changes and preventing skin contact with waste.
2Ease of operation
If the diaper contains a collection pouch for fecal matter, then skin irritation is reduced, but the diaper structure becomes more complex
Solution Approach 1:
The collection pouch, absorbent core, and barrier layers are merged into a single integrated diaper unit with defined boundaries. This merging maintains ease of operation by providing a complete solution while organizing complexity into manageable functional components.
Solution Approach 2:
The diaper structure serves multiple functions simultaneously: the collection pouch contains fecal matter, the absorbent core manages urine, and the barrier layer prevents leakage. This multi-functionality consolidates several waste management tasks into one device, improving ease of operation without proportionally increasing complexity.
3Object-generated harmful factors
If fecal matter is contained in a pouch, then mess during changing is reduced, but the diaper requires more complex structure
Solution Approach 1:
The collection pouch utilizes flexible barrier layers and thin film structures to contain fecal matter securely. These flexible materials conform to the wearer's body while maintaining containment, reducing spillage during changes without requiring rigid or overly complex structural elements.
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 diaper effectively contains fecal matter within a pouch, reducing skin irritation and making diaper changes less messy by separating waste from the skin, enhancing user comfort and caregiver convenience.
Implementation Method 1
an absorbent core defining a top surface thereof and an opposite underside surface overlying the inner side of the backing layer
Implementation Method 2
at least a substantial portion of the underside surface being unconnected to at least a substantial portion the inner side of the backing layer

AI summary
A diaper comprises a backing layer defining an outer side and an opposite inner side. An absorbent core defines a top surface and an opposite underside surface overlying the inner side of the backing layer. At least a substantial portion of the underside surface is unconnected to at least a substantial portion the inner side. An opening is formed along a length of the absorbent core extending from the top surface to the underside surface. A peripheral border structure surrounds the backing sheet and the absorbent core and is integrated therewith. The peripheral border structure and the unconnected portions of the underside surface and the inner side form a pouch therebetween accessible via the opening. When the diaper is worn by a user, the opening is positioned about the anus of a user for providing for fecal matter to enter the pouch during defecation.
