Solution Overview

Problem

Current absorbent articles for incontinence often fail to provide a comfortable and secure fit, leading to issues like Incontinence Associated Dermatitis (IAD), skin irritation, and inefficient manufacturing processes due to the need for multiple sizes and complex design features.

Innovation Solution

The development of absorbent articles with a chassis having a common width and adjustable lengths, featuring securement portions with varying widths and elastic panels, which accommodate different body sizes without requiring extensive machine changes, reducing manufacturing costs and environmental impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple sizes are created to accommodate different body proportions, then fit and comfort are improved, but manufacturing complexity and cost increase

Engineering Contradiction:
Improvefit for different body proportionsVSAvoidnumber of size components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The absorbent article is designed with a universal chassis width that can accommodate multiple body proportions through adjustable length configurations. The side panels are engineered to be foldable and reconfigurable, allowing a single article design to serve multiple size categories (small, medium, large) by adjusting panel positions and folds, thereby eliminating the need for completely separate size-specific components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The side panels incorporate dynamic folding mechanisms that allow caregivers to reconfigure the article fit in real-time. The panels can be folded along predetermined lines to create different dimensional configurations, transforming a static single-size design into a dynamically adjustable multi-size solution that adapts to various body proportions.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If multiple sizes with different components are manufactured, then fit accuracy is improved, but manufacturing downtime increases

Engineering Contradiction:
Improvesize-specific fit accuracyVSAvoidmachine changeover time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

A single universal chassis design with standardized components serves multiple size requirements. The side panels are designed with universal attachment points and fold lines that work across all size configurations, allowing the manufacturing machine to produce one standardized base product that can be field-adjusted to multiple sizes, eliminating repeated machine changeovers for different size components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The article is segmented into modular components where the chassis remains constant and only the side panel configurations vary. This segmentation allows the main chassis to be manufactured once per production run while the side panels can be adjusted post-manufacturing to create different size specifications, separating the manufacturing process from the size customization process.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If stretch material is added to accommodate larger waists, then adaptability is improved, but skin irritation risk increases

Engineering Contradiction:
Improveaccommodation of larger waist sizesVSAvoidskin irritation and breakdown
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

Instead of using stretch material that continuously exerts force on the skin, the side panels use dynamic folding mechanisms that provide accommodation through geometric adjustment rather than elastic tension. The panels can be folded to increase waist circumference accommodation without requiring stretchy materials that contact and irritate the skin, separating the adaptation function from skin contact.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The stretch function is extracted from the skin-contacting portions of the article. The elastic or stretchy material is removed from the waistband and leg opening areas that directly contact skin, replacing it with foldable panel structures that provide size adjustment through geometry rather than material elasticity, thereby eliminating the source of skin irritation while maintaining adaptability.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of manufacture

If front panels are shortened to offset stretch material cost, then manufacturing cost is reduced, but caregiver application difficulty increases

Engineering Contradiction:
Improvecost offset for stretch materialVSAvoidcaregiver application technique
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The front panel is segmented into functional zones with extended length in specific areas to provide larger attachment surfaces for the side panels. This segmentation allows the panel to maintain sufficient area for easy caregiver application while using cost-effective materials in non-stretch configurations, balancing manufacturing cost with ease of operation through strategic length distribution.

Inventive Principle:
Principle #1Segmentation

AI summary

An absorbent article includes a chassis having a substantially rectangular shape a first portion, a second portion and a crotch portion extending between the first and second portion, a portion of the chassis being configured to absorb fluids. The absorbent article includes a first securement portion operatively coupled to the first portion of the chassis. The absorbent article includes a second securement portion operatively coupled to the second portion of the chassis and configured to releasably attach to the first securement portion. The chassis is configured to include one of a first chassis length or a second chassis length. When the chassis includes the first length, the chassis includes a first width and the first securement portion includes a second width, and when the chassis includes the second length, the chassis includes the first width and the first securement portion includes a third width, greater than the second width.
