Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorbent articles often fail to provide an adequate fit to the body, leading to increased leakage of body exudates and discomfort during wear.
Innovation Solution
A method of manufacturing an exudate management layer with a first component and a second component, where the exudate management layer is formed using a cutting roller with specific cutting tools and vacuum systems to create a layered structure that enhances conformity to the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional flat absorbent articles are used, then manufacturing is simple, but they fail to conform to the contoured body leading to leakage
Solution Approach 1:
The exudate management layer is divided into multiple components (first component with opening, second component) that can be separately formed and then assembled. This segmentation allows each component to be optimized for specific functions while collectively achieving complex body conformance without requiring the entire structure to be monolithically complex
Solution Approach 2:
The patent transitions from flat 2D absorbent articles to 3D contoured structures by forming components with varying heights and profiles. The first and second components are positioned in overlapping configurations creating vertical dimensionality that enables the product to conform to the curved surfaces of the body, moving beyond simple planar geometry
2Reliability
If flat absorbent articles are used, then manufacturing process is simple, but movement causes deformation and fold lines that create leakage pathways
Solution Approach 1:
The exudate management layer components are pre-formed with specific shapes, openings, and overlapping configurations before being integrated into the final absorbent article. This preliminary formation of contoured structures allows the components to maintain their shape and resist deformation during wear, preventing the creation of leakage pathways while the manufacturing process remains manageable through modular construction
Solution Approach 2:
The exudate management layer components are constructed as flexible structures that can adapt to body movement without creating rigid fold lines. The overlapping configuration of the first and second components allows for flexibility and movement while maintaining structural integrity and preventing leakage pathways, balancing reliability with manufacturability
3Reliability
If conventional absorbent articles are used, then product structure is simple, but they create gaps between the product and skin resulting in leakage
Solution Approach 1:
The exudate management layer is segmented into functionally distinct first and second components with different heights and configurations. This segmentation allows the first component (with opening) and second component to work together in an overlapping arrangement that reliably manages exudates while the modular nature keeps manufacturing feasible through standardized assembly processes
Solution Approach 2:
By introducing vertical dimensionality through components of different heights positioned in overlapping configurations, the patent eliminates gaps between the product and skin without requiring excessively complex multi-layer structures. The height variations create effective sealing and management zones that improve exudate retention while maintaining reasonable structural complexity

AI summary
An absorbent article can have a topsheet layer, a liquid impermeable layer, and an absorbent core positioned between the topsheet layer and the liquid impermeable layer. The absorbent article can further include an exudate management layer in fluid communication with the topsheet layer. In various embodiments, the exudate management layer can be positioned on a body facing surface of the topsheet layer. In various embodiments, the exudate management layer can be positioned between the topsheet layer and the absorbent core. The exudate management layer has a first component which defines an opening for direct passage of body exudates into the absorbent core. The exudate management layer has a second component which at least partially overlaps the first component of the exudate management layer and further extends in the longitudinal direction of the absorbent article in a direction towards the posterior region of the absorbent article.
