Segmented Disposable Waste Containment Articles for Skin Irritation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable absorbent articles often cause skin irritation due to close contact with large absorbent materials and fail to effectively separate urine and feces, leading to inadequate waste collection and potential skin health issues.
Innovation Solution
A disposable waste containment article designed to collect body waste from specific orifices, featuring a bodyside and garment facing layer with an absorbent layer in between, a seal to secure the layers, and a body adhesive to attach to the skin, allowing for separate collection of urine and feces to prevent contact and irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a unitary disposable absorbent article covering the entire crotch area is used to collect both urine and feces, then waste collection capability is improved, but skin irritation increases due to close contact with large absorbent material
Solution Approach 1:
The invention divides the waste collection function into separate articles: one article for urine collection and another for feces collection. Each article is smaller and targeted to specific body regions, reducing the total skin contact area while maintaining effective waste collection for each type separately.
2Reliability
If a closely fitted absorbent article is used to collect waste, then waste containment is improved, but skin health deteriorates due to prolonged contact with waste material
Solution Approach 1:
By separating urine and feces collection into different articles worn at different locations, each article can be less bulky and better fitted, reducing prolonged skin contact with waste material while maintaining containment effectiveness.
Solution Approach 2:
The invention introduces separate collection articles as intermediaries between the waste orifices and the skin, creating a barrier that prevents direct and prolonged contact between waste material and skin, thereby protecting skin health.
3Object-affected harmful factors
If separate disposable urine and feces management devices are used, then skin contact with waste is reduced, but device complexity and manufacturing cost increase
Solution Approach 1:
The invention employs simple, disposable articles with basic absorbent structure and adhesive backing. Each article is designed for single use with minimal components, reducing manufacturing complexity and cost while effectively reducing skin contact with waste.
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 solution provides a comfortable, environmentally friendly, and economical option that effectively separates urine and feces, reducing skin irritation and maintaining a healthier skin pH by preventing urease action, suitable for nursing and geriatric facilities.
Implementation Method 1
An absorbent layer is positioned between the bodyside layer and the garment facing layer
Implementation Method 2
capillary action and adsorption
Implementation Method 3
A seal bonds at least a portion of the bodyside layer to the garment facing layer
Implementation Method 4
A body adhesive is secured to at least a portion of the first surface

AI summary
A disposable waste containment article is disclosed along with a combination of using two articles simultaneously. The article includes a bodyside layer having a first surface and an outer perimeter, and a garment facing layer having an outer perimeter approximately coincident with the outer perimeter of the bodyside layer. An absorbent layer is positioned between the bodyside layer and the garment facing layer. A seal secures the bodyside layer to the garment facing layer. The seal is located inward of the outer perimeters. An ingress is formed in the bodyside layer and is aligned with one of the waste orifices present in a human body such that waste from the human body can pass through the ingress and be collected in the waste containment article. The waste containment article also includes a body adhesive for securing the first surface to the wearer' s body.
