Absorbent Article Deformable Top Component Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Absorbent articles, such as feminine care products, often experience leakage due to inadequate body fit and fluid containment, particularly in public settings, which can lead to discomfort and avoidance of certain situations for users.
Innovation Solution
The development of an absorbent article with a movable top component that conforms to the body's shape, featuring a deformable design with a fluid-shrinkable string and translucent cantilevered region, enhancing body fit and leakage protection while maintaining a balanced aesthetic appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the absorbent article uses a traditional fixed top component design, then the manufacturing process is simple, but the body fit is inadequate and leakage occurs
Solution Approach 1:
The top component is designed with fluid-shrinkable strings attached in specific patterns that activate upon fluid contact, transforming the component from a static flat structure to a dynamic three-dimensional contoured shape that adapts to body curvature, thereby improving body fit and leakage protection without requiring complex pre-formed structures
Solution Approach 2:
The top component utilizes materials and structures that change physical parameters in response to fluid exposure, specifically shrinking in dimension along predetermined lines when exposed to fluid, which automatically creates the desired three-dimensional shape and body contact without manual intervention or complex manufacturing
2Reliability
If the absorbent article adds more bulk to improve fluid containment, then leakage protection improves, but the article appears too large and uncomfortable
Solution Approach 1:
The top component transitions from a two-dimensional flat structure to a three-dimensional contoured form through fluid-activated shrinkage, creating vertical depth and body contact without increasing the horizontal footprint or overall article bulk, thus providing fluid containment while maintaining a compact appearance
Solution Approach 2:
The three-dimensional shape is formed by nesting the shrunken portions of the top component into the absorbent article body, creating a compact configuration that provides fluid containment barriers without adding external bulk, as the containment structure is integrated within the existing article dimensions
3Reliability
If the absorbent article uses a deformable top component with fluid-shrinkable strings, then body fit and leakage protection improve, but the manufacturing complexity increases
Solution Approach 1:
The top component is divided into functional zones by attaching fluid-shrinkable strings in specific patterns, creating segmented regions that shrink independently upon fluid contact to form the desired three-dimensional shape, allowing for simplified manufacturing of flat components that self-assemble into complex configurations
Solution Approach 2:
The top component performs its own shaping function through fluid-activated shrinkage of attached strings, eliminating the need for complex pre-forming or manual shaping processes during manufacturing, as the component automatically contours to the body when exposed to fluid
4Shape
If the absorbent article maintains a flat top component design, then the apparent bulk is minimized, but the body contact and fluid containment are insufficient
Solution Approach 1:
The top component maintains a flat, minimal-bulk appearance in its inactive state but dynamically transforms into a three-dimensional body-contouring shape when exposed to fluid, providing optimal body contact and fluid containment only when needed, thus balancing aesthetics with functionality
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 improved body fit and reduced leakage risk, allowing users to maintain an active lifestyle without bulkiness, ensuring confidence even on heavy-flow days by effectively containing fluids and maintaining a comfortable, non-bulky appearance.
Implementation Method 1
a fluid shrinkable string attached to the deformable top component in a pattern capable of deforming the peripheral edge of the top component in the z-direction to form a raised cantilevered region

AI summary
An absorbent article is configured for controlled deformation when insulted by a user and includes an absorbent body having a body-facing surface, a garment-facing surface, and a first graphic visible at the body-facing surface; and a deformable top component positioned adjacent to the body-facing surface, the top component having a longitudinal direction, a transverse direction, a longitudinally-extending centerline, a transverse-extending centerline, and a peripheral edge, wherein the top component includes an attached region and a cantilevered region, and wherein the cantilevered region includes a translucent portion through which the first graphic is at least partially visible. The article also includes a fluid shrinkable string attached to the deformable top component in a pattern capable of providing forces to the top component when insulted by a user.
