Solution Overview

Problem

Conventional absorbent personal care articles with foldable wings often fail to prevent bunching or twisting, leading to reduced effectiveness in fluid absorption and increased leakage due to improper placement and movement-induced deformation.

Innovation Solution

The design features left and right flaps with specific peak and furrow configurations that intermesh or form discrete overlap areas when folded, with fasteners positioned to secure the wings flat against the backsheet, ensuring proper positioning and minimizing movement-induced deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional wings are used to secure the article to undergarments, then the article can be attached to the undergarment, but the article becomes prone to bunching and twisting due to movement stresses

Engineering Contradiction:
Improveattachment stabilityVSAvoidarticle shape stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The wing is divided into multiple peaks (first peak, second peak) and furrows that create segmented folding sections. This segmentation allows each section to independently accommodate movement stresses without causing overall bunching or twisting of the article.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wing features asymmetric peak and furrow configurations where the first peak and second peak are positioned at different locations relative to the furrow. This asymmetric design creates a specific folding geometry that prevents twisting while maintaining secure attachment.

Inventive Principle:
Principle #4Asymmetry

2Reliability

If wings are made to fold around the undergarment, then the article can be secured in place, but improper placement occurs leading to reduced absorption effectiveness

Engineering Contradiction:
Improveplacement securityVSAvoidplacement accuracy
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The wing is pre-formed with specific peak and furrow geometries during manufacturing. This preliminary shaping guides the user during application, ensuring correct placement around the undergarment without requiring complex folding maneuvers.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The peak and furrow configuration is designed to automatically align and secure itself to the undergarment through simple folding actions. The geometry self-guides the placement process, eliminating the need for precise manual positioning by the user.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the article is twisted or bunched, then the wings can be fastened to the undergarment, but the article becomes angled relative to the wearer reducing fluid absorption

Engineering Contradiction:
Improvefastening easeVSAvoidfluid absorption effectiveness
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The segmented peak and furrow structure allows the wing to fold in a controlled manner that maintains article alignment with the wearer's body, preventing twisting while still enabling easy fastening.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wing geometry is designed in advance to counteract the natural tendency to twist or bunch during folding. The peak and furrow configuration creates opposing forces that maintain article flatness and proper orientation during the fastening process.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

An absorbent personal care article, such as a sanitary napkin or incontinence pad, having a longitudinal centerline and a transverse centerline and including a pair of opposed first and second wings extending along the longitudinal sides of the article. The first wing includes two or more peaks with furrows there between and the second wing includes one or more peaks. The peaks of the first and second wings are sized and positioned on the article such that when folded under the article and around the wearer's undergarments, the peak of the second wing extends across the longitudinal centerline of the article and into the furrow of the first wing. The inter-meshing wings help wearer's properly don the articles, improve the attachment of the article to the wearer's garment and/or reduce unwanted twisting or bunching of the article during use.
