Disposable Absorbent Article Interior Design Signal
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
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
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.
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.
