Skin-Adhering Absorbent Article for Discreet Fluid Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorbent personal care articles are uncomfortable to wear, prone to leakage, and lack discretion due to their design and attachment methods, which can cause bunching or twisting, leading to discomfort and visibility issues.
Innovation Solution
A body-adhering absorbent article with a shell designed to attach directly to the skin, featuring a breathable material and adhesive properties, specifically shaped for the vulva region, providing a barrier between clothing and the body while minimizing visible silhouette and preventing premature leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If absorbent articles are attached to underwear or undergarment using adhesive and flaps, then the absorbent article is held in place during use, but the article becomes bunched or twisted during body movement causing discomfort
Solution Approach 1:
The patent introduces a body-adhering layer as an intermediary between the absorbent article and the user's body. This layer includes adhesive regions that directly bond to skin, eliminating the need for flaps and intermediate undergarments. The body-adhering layer moves with body contours without bunching or twisting, resolving the contradiction between reliable attachment and comfort during movement.
Solution Approach 2:
Instead of attaching the absorbent article to undergarments (traditional approach), the patent inverts the attachment strategy by having the absorbent article adhere directly to the body. The body-facing surface of the backsheet includes adhesive regions that bond to skin, reversing the conventional hierarchy and eliminating the problems associated with flap-based attachment to undergarments.
2Ease of manufacture
If absorbent articles are designed with traditional shape and size for undergarment attachment, then they can be attached to underwear, but they are uncomfortable to wear and visible through clothing
Solution Approach 1:
The patent applies local quality by creating a thin, conformable body-adhering layer with specific adhesive properties only where needed on the backsheet. This layer is positioned to contact the body directly without adding bulk, providing attachment capability while maintaining comfort and discretion. The adhesive regions are strategically placed to ensure secure bonding without requiring traditional bulky construction.
3Reliability
If adhesive is applied to the body-facing surface of the top sheet, then the absorbent article adheres to skin, but the design remains the same as undergarment-attached articles lacking comfort improvements
Solution Approach 1:
The patent moves the adhesive application to another dimension by placing adhesive regions on the body-facing surface of the backsheet rather than the top sheet. This dimensional shift allows the adhesive to bond the entire absorbent article assembly directly to the body, with the backsheet serving as the primary attachment surface. This approach enables secure skin adhesion while allowing the top sheet and absorbent core to maintain their functional design without compromising 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 absorbent article offers improved comfort, reduced leakage risk, and enhanced discretion by adhering directly to the skin, providing a secure and discreet protection against bodily fluids without the need for underwear, while maintaining a comfortable fit and breathability.
Implementation Method 1
a body-facing surface of the back sheet has adhesive material positioned thereon
