Solution Overview

Problem

Absorbent garment-like articles for incontinence often suffer from bulkiness, poor fit, and visibility issues due to bunching of absorbent material, leading to discomfort and stigma for users.

Innovation Solution

The design features a front and back region with elastomeric panels and an absorbent core configuration that minimizes bulk by positioning the absorbent core and elastic materials to ensure a snug fit and reduce visibility, with specific placement of the absorbent core and elastic materials to prevent bunching and enhance discretion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If elastic materials are positioned over and around the absorbent material to improve fit, then the garment provides better containment and comfort, but the absorbent material bunches up creating bulkiness and visibility issues

Engineering Contradiction:
Improvefit qualityVSAvoidbulkiness
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The absorbent core is divided into multiple zones with different compression characteristics. High-compression zones are positioned in areas where discretion is most important (front and back waist regions), while lower compression zones are placed in the crotch area. This segmentation allows the garment to provide snug fit without uniform bunching throughout the entire absorbent material.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the absorbent core are subjected to different levels of elastic compression. The front and back regions use higher compression elastic materials to reduce bulk and improve discretion, while the crotch region uses lower compression to maintain comfort and absorbency. This local differentiation of compression quality resolves the contradiction between fit and bulkiness.

Inventive Principle:
Principle #3Local quality

2Reliability

If elastic materials are used to ensure close-to-body fit, then leakage is reduced and comfort is improved, but the product becomes more bulky and visible under clothing

Engineering Contradiction:
Improveleakage preventionVSAvoidvisibility
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The elastic compression is segmented into high-compression zones at the front and back waist regions and lower-compression zones in the crotch area. This segmentation maintains leakage prevention through strategic compression points while reducing overall bulk and visibility under clothing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

High-compression elastic materials are applied locally to the front and back regions where discretion is most critical, rather than uniformly across the entire garment. This local quality approach ensures reliability for leakage prevention in key areas while minimizing bulkiness and visibility in areas where the garment is most likely to be seen.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If uniform elastic compression is applied throughout the absorbent material, then fit is improved, but the absorbent material bunches up excessively creating discomfort and stigma

Engineering Contradiction:
Improvefit qualityVSAvoidbunching
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The uniform compression is replaced with segmented compression zones of varying intensity. The front and back regions receive higher compression to prevent bunching and improve fit, while the crotch region receives lower compression to maintain comfort. This segmentation eliminates excessive bunching while preserving fit quality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different compression levels are applied to different regions based on their specific functional requirements. The front and back regions use higher compression elastic materials to reduce bunching, while the crotch area uses lower compression to prevent discomfort. This local differentiation of compression quality resolves the contradiction between fit and bunching.

Inventive Principle:
Principle #3Local quality

AI summary

An absorbent article, such as, a garment-like absorbent article, can have a front region, a back region, and a crotch region extending between and interconnecting the front region and the back region. Each of the front region and the back region can have an elastic material. The absorbent article can have an absorbent core wherein a portion of the absorbent core can be located in the crotch region, a portion of the absorbent core can be located in a portion of the front region, and a portion of the absorbent core can be located in a portion of the back region. Within each of the front region and the back region, an overlapping region can exist where the absorbent core is in an overlapping configuration with the elastic material within the front region and the back region.
