Solution Overview

Problem

Existing absorbent articles, such as taped diapers, have flat, non-patterned front ears that are aesthetically unpleasing and difficult to grasp, which affects their functionality and user experience.

Innovation Solution

Incorporating patterned front ears with three-dimensional features into absorbent articles to enhance their aesthetic appeal and ease of grasping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If flat, non-patterned front ears are used, then manufacturing cost is reduced and production is simplified, but aesthetic appeal deteriorates and ease of grasping is reduced

Engineering Contradiction:
Improvefront ear manufacturing simplicityVSAvoidease of grasping
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The front ears incorporate three-dimensional features including raised patterns and tactile elements that add vertical dimensionality to the otherwise flat structure. This dimensional enhancement provides grasping surfaces and tactile feedback without significantly complicating the manufacturing process, as these features can be integrated during the forming or bonding stages of the nonwoven material.

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

Solution Approach 2:

The front ears feature localized patterned regions with varying textures and heights concentrated in specific areas, particularly in the grasping zones. These local variations in quality provide enhanced tactile properties and grasping characteristics while maintaining overall manufacturing simplicity, as only specific portions require the added complexity of patterning rather than the entire component.

Inventive Principle:
Principle #3Local quality

2Ease of manufacture

If flat, non-patterned front ears are used, then manufacturing cost is reduced, but aesthetic appeal deteriorates

Engineering Contradiction:
Improvefront ear manufacturing simplicityVSAvoidaesthetic appeal
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

Three-dimensional patterns and surface variations are incorporated into the front ears, adding visual depth and aesthetic interest while maintaining a relatively simple overall structure. The raised patterns and textured surfaces create visual appeal without requiring complex multi-component assemblies, as these features are integrated into the front ear material itself during manufacturing.

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

Solution Approach 2:

Patterned regions with enhanced visual characteristics are localized to specific areas of the front ears, providing aesthetic appeal in key visual zones while keeping other areas simpler and easier to manufacture. This selective application of patterning allows for cost-effective production by applying complexity only where it most impacts appearance.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If patterned front ears with three-dimensional features are added, then aesthetic appeal and ease of grasping are improved, but device complexity increases

Engineering Contradiction:
Improveease of graspingVSAvoidfront ear structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patterning and three-dimensional features are merged directly into the front ear material itself rather than being added as separate components or attachments. This integration combines the structural function with the aesthetic and tactile functions in a single element, reducing overall device complexity by eliminating the need for additional parts while still providing enhanced grasping and visual properties.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patterned front ears serve multiple functions simultaneously: they provide structural support, enable easy grasping through tactile features, enhance aesthetic appeal through visual patterns, and maintain the functional integrity of the absorbent article. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity despite the enhanced capabilities.

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

AI summary

An absorbent article comprises a front waist region, a back waist region, a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core positioned at least partially intermediate the topsheet and the backsheet. The absorbent core may comprise an absorbent material. The absorbent article may comprise a pair of back ears in the back waist region and a pair of front ears in the front waist region. The front ears may comprise a pattern. The pattern may comprise three-dimensional features and/or visually distinguishable zones.
