Solution Overview

Problem

Current compressed packages of disposable absorbent articles often have a difficult-to-find opening feature and require strong opening mechanisms that can withstand the compressive force, making it hard for users, especially geriatric individuals or those with medical conditions, to easily access and remove the first few absorbent articles.

Innovation Solution

A flexible package design with a gusset-based opening feature that includes a line of weakness extending through the gusset, allowing users to easily grip and open the package by applying a threshold force, facilitating access to the absorbent articles while withstanding the compressive forces applied by the articles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the opening feature is made strong to withstand compressive forces, then packaging integrity is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvepackaging integrityVSAvoidease of opening
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The opening feature is divided into a tear-initiation portion and a tear-propagation portion, allowing the packaging to be opened with reduced force while maintaining integrity during normal handling. The segmentation enables controlled tearing at a specific location without requiring excessive force throughout the entire packaging structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A gusset structure serves as an intermediary element between the compressed absorbent articles and the opening feature. The gusset provides structural support to withstand compressive forces while the integrated line of weakness allows easy opening, mediating between the conflicting requirements of strength and ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Volume of stationary object

If the packaging is compressed to reduce volume, then distribution costs are reduced, but ease of operation deteriorates

Engineering Contradiction:
Improvepackage volumeVSAvoidease of article removal
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The packaging structure is segmented with a dedicated opening feature that includes a line of weakness, separating the compression function from the opening function. This allows the majority of the packaging to remain compressed for volume efficiency while the opening feature provides a localized point of reduced resistance for easy article removal.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The line of weakness is pre-formed in the packaging structure during manufacturing, creating a predetermined path of reduced strength before use. This preliminary action ensures that when the user needs to open the package, the tearing action follows the pre-prepared path, making article removal easier despite the overall compressed state.

Inventive Principle:
Principle #10Preliminary action

3Shape

If the opening feature is made subtle to maintain aesthetics, then packaging appearance is improved, but detectability deteriorates

Engineering Contradiction:
Improvepackaging appearanceVSAvoidopening feature detectability
Core Design Contradiction:
ShapeVSDifficulty of detecting and measuring

Solution Approach 1:

Indicia are applied to the packaging that visually indicate the location of the opening feature. These visual cues use color or graphical elements to draw attention to the subtle opening feature, allowing the packaging to maintain its aesthetic appearance while improving the detectability of the opening location for consumers.

Inventive Principle:
Principle #32Color changes

AI summary

A package includes a plurality of disposable absorbent articles and a packaging having a front panel, a back panel, a top panel, a bottom panel, and a pair of side panels. The panels cooperatively define an interior compartment. At least one of the side panels has a longitudinal central axis, a pair of side edges, a gusset disposed adjacent the top panel, and a line of weakness having a first portion disposed on one side of the longitudinal central axis, a second portion disposed on the opposite side of the longitudinal central axis, and a third portion spanning between and connecting the first and second portions. The third portion of the line of weakness is spaced from the ends of the first and second portions. The plurality of disposable absorbent articles is compressed within the interior compartment and arranged in at least one row extending between the side panels.
