Multi-Color Absorbent Article Visual Signal Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Absorbent articles with narrow central colored regions may lead consumers to incorrectly assume that stains outside this region indicate exhausted absorbent capacity, causing concern about leaks, while wider distribution of fluid can increase capacity but risks bulkier appearance and discomfort.
Innovation Solution
An absorbent article design featuring a central colored region coincident with the longitudinal centerline, an intermediate colored region radially circumscribing over 90% of the central region, and an outer colored region, all viewable from the body-facing surface, with distinct colors to provide a visual impression of adequate fluid storage capacity and secure retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a narrow central colored region is used, then the absorbent article maintains a slim appearance and comfortable fit, but consumers may mistakenly believe that stains outside this region indicate exhausted absorbent capacity
Solution Approach 1:
The colored region is segmented into multiple concentric zones (inner colored region, intermediate colored region, and outer colored region) with different colors. This segmentation allows each zone to convey specific information about absorbent capacity to consumers while maintaining the overall slim appearance of the article.
Solution Approach 2:
Different regions of the absorbent article are assigned different colors to indicate different levels of absorbent capacity. The inner, intermediate, and outer colored regions use distinct colors to communicate to consumers where fluid is expected and how much capacity remains, providing localized information without changing the overall article shape.
2Loss of information
If the central colored region is made larger to indicate adequate capacity, then consumers understand the absorbent capacity better, but the absorbent article appears bulkier and less comfortable
Solution Approach 1:
Instead of using one large colored region, the design segments the colored area into multiple concentric zones with different colors. This allows adequate visual indication of absorbent capacity while keeping the overall colored region perimeter relatively narrow, avoiding bulkiness.
Solution Approach 2:
The design uses radial dimension (concentric circles) instead of only expanding the central area. By circumscribing colored regions in a radial pattern, the design communicates capacity information through the arrangement and color differentiation of zones rather than increasing the overall footprint of the colored area.
3Quantity of substance
If fluid is widely distributed in the absorbent article to increase capacity, then the absorbent capacity increases, but stains may travel beyond the central colored region causing consumer concern
Solution Approach 1:
Different colored regions are assigned to different areas of the absorbent article to indicate where fluid is expected to be absorbed. The intermediate and outer colored regions visually mark the boundaries of expected fluid distribution, helping consumers understand that stains within these regions are normal and do not indicate leakage.
Solution Approach 2:
The multi-colored visual signal system provides feedback to consumers about the state of the absorbent article. By showing different colors in concentric regions, the system communicates to consumers whether fluid is within expected boundaries, allowing them to assess whether the absorbent capacity is being utilized normally or if leakage is occurring.

AI summary
An absorbent article having a central colored region, an intermediate colored region, an outer colored region, and a background region. The intermediate colored region can be between the central colored region and the outer colored region. The intermediate colored region can substantially circumscribe the central colored region. The central colored region, intermediate colored region, and outer colored region differ in color from the background region.
