Polymer Film Odor Control for Disposable Absorbent Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable absorbent articles lack effective odor control and skin health benefits, as existing technologies do not efficiently release agents to manage odor and provide skin wellness benefits upon contact with bodily fluids.
Innovation Solution
A polymer film integrated into disposable absorbent articles that releases odor control and skin health agents upon contact with bodily fluids, formulated to provide immediate or gradual release of agents, including pH regulators, anti-fungal agents, and fragrances, which can be positioned within the article or applied directly to the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional absorbent articles are used with traditional odor control compositions, then basic odor control is provided, but the release of agents is not effective or timely upon contact with bodily fluids
Solution Approach 1:
The patent employs a polymer film as a thin flexible barrier that controls the release of odor control agents. This film is positioned within the absorbent article to contact bodily fluids and release agents in response, providing timely and effective odor control while maintaining the integrity of the absorbent core.
Solution Approach 2:
The polymer film's properties are designed to change in response to contact with bodily fluids, triggering the release of odor control agents. This parameter change (from intact to activated state) ensures that agents are released at the appropriate time and under the right conditions, improving both reliability and productivity of odor control.
2Adaptability or versatility
If multiple functional agents are incorporated into the absorbent article, then skin health benefits are enhanced, but the complexity of the article structure increases
Solution Approach 1:
The polymer film is designed to perform multiple functions simultaneously: it acts as a barrier, controls the release of odor control agents, and delivers skin health benefits through incorporated agents. This multi-functionality approach allows the system to provide diverse benefits without proportionally increasing structural complexity.
Solution Approach 2:
The patent combines odor control agents and skin health agents within a single polymer film structure, which is then integrated into the absorbent article. This merging of multiple functional components into one delivery system reduces overall structural complexity while maintaining versatility.
3Speed
If the polymer film is designed to release agents immediately upon contact with bodily fluids, then rapid odor control is achieved, but gradual release over time is lost
Solution Approach 1:
The polymer film is designed to release agents in a periodic or staged manner, providing both immediate release upon contact with bodily fluids and continued gradual release over time. This periodic action ensures rapid initial odor control while maintaining prolonged protective effects.
Solution Approach 2:
The polymer film is pre-positioned within the absorbent article in contact with or adjacent to the absorbent core, so that agent release is immediately triggered upon contact with bodily fluids. This preliminary positioning ensures rapid response while the film's design allows for sustained release throughout the product's lifecycle.
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 polymer film effectively manages odor and provides skin wellness benefits by releasing agents upon contact with bodily fluids, enhancing the functionality of disposable absorbent articles and offering additional applications such as underarm deodorants and household cleaning pads.
Implementation Method 1
the polymer film can be positioned against or adjacent to the body of the user to be activated by contact with bodily fluids. Upon contact with bodily fluids, the polymer film can release odor control and/or skin wellness agents.
Implementation Method 2
the polymer film can be formulated to release the odor control and/or skin wellness agents immediately upon contact with bodily fluids, or gradually over a period of time after such contact.
Data Source
AI summary
A disposable absorbent article with an associated polymer film that is positioned to be activated by contact with bodily fluids, wherein the polymer film can release odor control and/or skin wellness agents upon contact with such bodily fluids. The polymer film can release the odor control and/or skin wellness agents immediately, gradually over a period of time after contact with such bodily fluids, or a combination of both. The polymer film can also be used for household cleaning applications, in which the polymer film can similarly contain and subsequently release household cleaning agents upon contact with water.
