Absorbent Insert With Segmented Core For Underwear-Like Garment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a disposable absorbent garment that resembles conventional underwear while effectively managing bedwetting, as existing products are often perceived as 'diaper-like' and do not meet the requirements of users seeking a more underwear-like solution.
Innovation Solution
A discrete absorbent insert is designed with a specific configuration, including intake materials and an absorbent core, positioned between sheets with a unique width distribution and intake rates, and is integrated into a containment pant with a fluid-impervious pouch and elastic features to provide effective urine management without the appearance of traditional diapers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If disposable absorbent garments are designed to look like conventional underwear, then aesthetic appearance is improved, but urine intake speed deteriorates
Solution Approach 1:
The absorbent garment is segmented into distinct functional zones: a first receiveable area with high intake speed for initial urine contact, and a second receiveable area with higher absorption capacity for subsequent urine. This segmentation allows the garment to simultaneously achieve quick intake (like traditional diapers) while maintaining an underwear-like overall appearance.
Solution Approach 2:
Different regions of the absorbent garment are assigned different material properties and absorption characteristics. The first receiveable area uses materials optimized for rapid urine intake, while the second receiveable area uses materials with higher total absorption capacity. This local differentiation resolves the contradiction by providing both quick intake and adequate absorption within an underwear-like design.
2Quantity of substance
If absorbent material quantity is increased to improve absorption capacity, then urine management effectiveness is improved, but garment thickness and bulk increase
Solution Approach 1:
The absorbent material is divided into two distinct receiveable areas with different functions. The first area is optimized for rapid urine uptake with appropriate material quantity, while the second area provides additional absorption capacity. This segmentation allows the garment to achieve high total absorption without requiring uniform thickening throughout the entire garment, thus maintaining a sleek underwear-like profile.
Solution Approach 2:
The garment employs composite material construction with different absorbent materials in different zones. The first receiveable area may use materials with high intake speed characteristics, while the second receiveable area uses materials with high absorption capacity. This composite approach enables the garment to provide adequate absorption capacity without increasing overall bulk, as each material is used where it is most effective.

AI summary
A discrete absorbent insert includes an absorbent core positioned between a first sheet and a second sheet. The first sheet and the second sheet extend beyond the core and are joined together to form a seal. The absorbent core has at least 40% superabsorbent. The absorbent insert has an intake layer of at least 100 gsm between the first sheet and the absorbent core. The first sheet and the second sheet are fluid permeable, spunbond webs of synthetic polymer filaments. The absorbent insert is devoid of a fluid-impervious layer and has an absorbent capacity of at least 600 g. The first end section of the absorbent core has a maximum width of at least 135 mm, the central section of the absorbent core has a maximum width of less than 90 mm, and the second end section of the absorbent core has a maximum width of at least 135 mm.
