Solution Overview

Problem

Existing packages of absorbent articles, such as diapers and sanitary napkins, are challenging to efficiently pack and unpack due to their design, making it difficult to remove individual articles, especially when the package is full or the articles are very thin.

Innovation Solution

The package design includes asymmetrically shaped absorbent articles with a maximum transverse dimension at one end and a smaller dimension at the other, positioned within a container such that their longitudinal axes are not parallel, allowing for easier retrieval and using a method of delivering and cutting absorbent material to create absorbent cores that are combined with topsheets and backsheets for packaging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If absorbent articles are tightly packed in the container, then the package efficiency is improved, but the ease of removing individual articles deteriorates

Engineering Contradiction:
Improvepackage efficiencyVSAvoidease of removing articles
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The absorbent articles are shaped asymmetrically in the transverse dimension, with one end having a maximum transverse dimension and the other end having a smaller transverse dimension. This asymmetric shape allows articles to be nested together efficiently while maintaining accessibility for removal.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The absorbent articles are positioned within the container in a nested arrangement where articles are disposed at different orientations. The asymmetric shape enables one article to be partially inserted within another, maximizing space utilization while allowing easy access to individual articles.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Device complexity

If absorbent articles are positioned with longitudinal axes parallel, then the packing is simplified, but the ease of removing individual articles deteriorates

Engineering Contradiction:
Improvepacking complexityVSAvoidease of removing articles
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

Articles are positioned with their longitudinal axes at non-parallel orientations within the container. This angular arrangement, combined with the asymmetric shape, creates a stable nested configuration that simplifies the overall packing structure while maintaining ease of article removal.

Inventive Principle:
Principle #4Asymmetry
