Segmented Pet Absorbent Article for Bedridden Waste Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorbent articles for pet animals, particularly aged ones, tend to cause pressure sores and leakage issues when the pet is bedridden, as they become stuffy and wet under body weight, leading to soiling and floor contamination.
Innovation Solution
An absorbent article with a longitudinal design featuring a tail-facing area and separate sections to cover both sides of the pet's rump, incorporating a liquid-permeable interior layer, a liquid-impermeable exterior layer, and an absorbent core, with elastic elements and barrier sheets to prevent leakage and maintain absorbency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional absorbent article is used for bedridden pet animals, then the pet animal can be contained, but the inside of the absorbent article becomes stuffy and wet under body weight, causing pressure sores
Solution Approach 1:
The absorbent article is divided into a first section and a second section that can be positioned on either side of the pet animal's body. This segmentation allows the article to accommodate bedridden pets lying on their side, distributing body weight more evenly and preventing stuffiness in one location while maintaining effective waste containment.
Solution Approach 2:
The article provides different functional zones: the first and second sections are designed to cover different sides of the pet's body with absorbent cores positioned to handle waste discharge. This local differentiation ensures that the absorbent functionality is concentrated where needed while other areas provide support without causing pressure sores.
2Object-affected harmful factors
If a pet sheet is laid on the floor instead of an absorbent article, then pressure sores may be prevented, but portions of the dog's body may be soiled and body waste may spread over the pet sheet and flow out to soil the floor
Solution Approach 1:
The absorbent article serves as an intermediary layer between the pet animal and the floor. It combines the benefits of both approaches: like the pet sheet, it allows the pet to lie comfortably without pressure sores; like the absorbent article, it contains and absorbs body waste to prevent soiling and leakage onto the floor.
Solution Approach 2:
The absorbent article is designed to perform multiple functions simultaneously: it provides a comfortable surface that prevents pressure sores, absorbs and contains body waste effectively, and prevents leakage onto the floor. This multi-functionality resolves the contradiction between comfort and containment.
3Reliability
If conventional absorbent articles are designed for standing or sitting pets, then they can effectively contain body waste, but they become ineffective when the pet is bedridden on its side
Solution Approach 1:
The absorbent article is designed with dynamic adaptability to accommodate different pet positions. The first and second sections can be positioned to match the pet's body orientation whether standing, sitting, or lying on the side, ensuring effective waste containment in all positions while maintaining comfort.
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 article effectively absorbs and contains pet waste without leakage, reduces stuffiness, and prevents pressure sores by distributing waste evenly and maintaining absorbency, even when the pet is bedridden on its side.
Implementation Method 1
an absorbent core disposed in the first and second sections
Implementation Method 2
the absorbent core interposed between the interior and exterior layer sheets

AI summary
Disclosed is an absorbent article for pet animals. The article has a longitudinal direction, a transverse direction, a body-facing surface, a non-body-facing surface and first and second ends opposed to each other in the longitudinal direction. The article includes: a tail facing area facing a pet animal's tail; a first section to cover one side of a pet animal's rump, extending from the tail facing area to the first end; a second section to cover the other side of the pet animal's rump, extending from the tail facing area to the second end; and an absorbent core disposed between the first and second sections.
