Segmented Absorbent Insert for Hygiene Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorbent articles are difficult to change, especially when away from home, due to bulkiness and side leakage issues when using stacked configurations, and require removal of clothing for replacing or applying a second clean product.
Innovation Solution
A multiple-use absorbent article system featuring a chassis absorbent unit with a removable absorbent insert, where the insert has a line of weakness for easy separation from the chassis, allowing for selective removal and replacement without removing clothing, enhancing user convenience and reducing bulkiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple absorbent articles are stacked in a compound configuration, then the user can remove one article at a time, but the product becomes bulky and causes side leakage
Solution Approach 1:
The absorbent insert is divided into a removable portion and a resident portion separated by a line of weakness. This segmentation allows the user to remove only the soiled portion while leaving the clean resident portion in place, eliminating the need to stack multiple complete articles and thereby reducing bulkiness while maintaining ease of changing
2Ease of operation
If multiple absorbent articles are stacked in a compound configuration, then the user can remove one article at a time, but side leakage problems occur
Solution Approach 1:
By segmenting the absorbent insert into removable and resident portions, the invention allows selective removal of only the soiled section. This prevents the need to stack multiple complete articles, thereby eliminating side leakage issues while maintaining the convenience of incremental changing
Solution Approach 2:
The soiled portion of the absorbent insert is extracted and removed from the chassis, leaving the clean resident portion intact. This extraction approach eliminates the harmful effect of side leakage that occurs with stacked configurations while preserving the ease of changing benefit
3Device complexity
If conventional absorbent articles are used, then the structure is simple, but changing is difficult and requires removal of clothing
Solution Approach 1:
The absorbent insert is segmented into removable and resident portions connected by a line of weakness. This simple segmentation allows the removable portion to be pulled out and discarded without removing clothing, significantly improving ease of changing while adding minimal complexity to the overall structure
Solution Approach 2:
The line of weakness is strategically positioned within the absorbent insert to create a localized separation zone. This local quality modification enables easy removal of the soiled portion while maintaining the integrity and simplicity of the overall article structure

AI summary
A multiple use absorbent article includes a chassis absorbent unit having a chassis topsheet, a chassis backsheet, and a chassis absorbent core sandwiched between the chassis topsheet and the chassis backsheet. The article also includes an absorbent insert bonded to the chassis absorbent unit, a removable portion of the absorbent insert configured to be selectively removable from the chassis absorbent unit, wherein the absorbent insert includes an insert topsheet, an insert backsheet, and an insert absorbent core sandwiched between the insert topsheet and the insert backsheet. The absorbent insert further includes a line of weakness that provides for separation of the absorbent insert into a removable portion configured to be removed from the chassis absorbent unit, and a resident portion that remains bonded to the chassis absorbent unit.
