Solution Overview

Problem

There is a need for a mechanism to communicate to caregivers that thinner disposable absorbent articles still provide adequate absorbency, as they often associate thicker articles with better absorbency.

Innovation Solution

Incorporating an interior design signal, such as a printed pattern or solid color, on the absorbent article to indicate improved absorbency and distribution, which can be located on the topsheet or other layers visible before use, to reassure caregivers of the article's performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the absorbent article is made thinner, then the wearing comfort and flexibility are improved, but the perceived absorbency by caregivers deteriorates

Engineering Contradiction:
Improvethickness of absorbent articleVSAvoidperceived absorbency
Core Design Contradiction:
Length of moving objectVSLoss of information

Solution Approach 1:

The patent applies color changes by incorporating an interior design signal with specific color characteristics ( brighter, more saturated colors) on the interior surface of the absorbent article. This visual signal communicates absorbency capability to caregivers without requiring the article to be thicker, thus resolving the contradiction between thinness and perceived absorbency.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent transitions from relying solely on physical thickness (one dimension) to communicate absorbency to using visual design signals on the interior surface (adding a visual dimension). This allows thin articles to convey absorbency information through color and pattern design, resolving the contradiction between reduced thickness and maintained perceived performance.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Length of moving object

If the absorbent article is made thinner, then the profile is reduced, but the visual indication of absorbency capability is reduced

Engineering Contradiction:
Improveprofile of absorbent articleVSAvoidvisual indication of absorbency
Core Design Contradiction:
Length of moving objectVSLoss of information

Solution Approach 1:

The patent uses color changes by implementing an interior design signal with specific color properties (brightness, saturation) that visually indicates absorbency capability. This allows the article to maintain a thin profile while compensating for the reduced visual indication through enhanced color design on the interior surface.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent introduces an intermediary element - the interior design signal - that mediates between the thin profile and the need for visual absorbency indication. This design signal acts as a visual mediator that communicates absorbency capability without requiring physical thickness, resolving the contradiction between profile reduction and visual indication.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If modern absorbent materials are used to create thinner articles, then the absorbent capacity is maintained, but caregiver confidence in absorbency is reduced

Engineering Contradiction:
Improveabsorbent capacityVSAvoidcaregiver confidence
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent applies color changes through the interior design signal that visually communicates absorbency capability to caregivers. This design signal compensates for the reduced physical presence of absorbent materials in thinner articles, thereby maintaining caregiver confidence while preserving absorbent capacity through modern materials.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent implements a visual feedback mechanism through the interior design signal that provides caregivers with visual confirmation of absorbency capability. This feedback loop reassures caregivers that despite the thinner profile and reduced visible absorbent material, the article maintains adequate absorbent capacity, thus resolving the contradiction between absorbent capacity and caregiver confidence.

Inventive Principle:
Principle #23Feedback
