Absorbent Body Compressed Points Vertical Wicking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorbent articles often fail to efficiently absorb and distribute body exudates, leading to discomfort and leakage due to poor vertical wicking and liquid distribution capabilities.
Innovation Solution
An absorbent body with a longitudinal and transverse direction, featuring multiple absorbent layers and pairs of compressed points that provide pathways for body exudates to travel from the upper surface to lower layers, enhancing vertical wicking and containing exudates in a localized area to reduce leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional absorbent articles are used, then they provide basic absorption function, but they fail to efficiently distribute body exudates and provide poor vertical wicking
Solution Approach 1:
The absorbent body incorporates a porous structure with channels and void spaces that enable efficient vertical wicking of body exudates from the topsheet through the absorbent core to the backsheet. The porous material allows capillary action to draw fluids downward while maintaining structural integrity for effective distribution throughout the absorbent article.
2Reliability
If body exudates are not efficiently distributed, then the absorbent article structure remains simple, but leakage and discomfort occur
Solution Approach 1:
The absorbent body is segmented into multiple functional layers including a topsheet layer, absorbent core with distributed channels, and backsheet layer. This segmentation creates distinct zones for fluid intake, vertical transport, and containment, improving leakage prevention while maintaining manageable structural complexity through modular design.
Solution Approach 2:
Different regions of the absorbent body are赋予 different properties: the topsheet provides fluid intake pathways, the absorbent core contains channels for vertical wicking and distribution zones for containment, and the backsheet provides leakage barrier. This local differentiation of qualities ensures each region performs its specific function optimally for comprehensive leakage prevention.
3Ease of operation
If body exudates remain on the upper layer, then the absorbent article is simple in structure, but wearer discomfort increases
Solution Approach 1:
The absorbent body incorporates three-dimensional vertical channels and void spaces that extend through the absorbent core, creating pathways for rapid vertical transport of body exudates from the upper surface to lower distribution zones. This dimensional structure enables efficient wicking while maintaining a compact overall profile suitable for wearable applications.
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 body effectively increases vertical wicking capability, decreases wearer discomfort, and reduces incidents of leakage by efficiently distributing body exudates throughout the absorbent article.
Implementation Method 1
Each of the compressed points can provide a pathway for body exudates to travel from the upper surface of the absorbent body and into the lower layer(s) of the absorbent body

AI summary
An absorbent body for use in an absorbent article can have an improved vertical wicking capability and an improved liquid distribution capability. The absorbent body can have at least a first absorbent layer and a second absorbent layer. The absorbent body can further have at least three pairs of compressed points. A first pair of compressed points can be separated from a second pair of compressed points by a first distance in the longitudinal direction of the absorbent body. A third pair of compressed points can be separated from the first pair of compressed points by a second distance in the transverse direction of the absorbent article. The second distance can be greater than the first distance.
