Solution Overview

Problem

Existing disposable absorbent articles, such as sanitary napkins and pantiliners, face challenges in showcasing aesthetic features while maintaining privacy and requiring a cost-effective manufacturing process that enhances user experience and product differentiation.

Innovation Solution

A process involving printing a continuous image on a film or web material with repeated indicia, cutting it into segments for individual wrapping, and stacking to recreate the image, allowing visible printed indicia on the outer surface of each pouch, which simplifies the cutting process and maintains a cohesive theme without registered demarcation lines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a non-transparent wrapper sheet is used to maintain privacy and hide soiled pads, then privacy protection is improved, but aesthetic features cannot be displayed

Engineering Contradiction:
Improveprivacy protectionVSAvoidaesthetic feature display
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The wrapper sheet is divided into multiple sections: a non-transparent portion for privacy protection and a transparent or translucent portion for displaying aesthetic features. This segmentation allows different functional requirements to be met in different areas of the same wrapper sheet.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different portions of the wrapper sheet have different transparency properties - the first portion is non-transparent while the second portion is transparent or translucent. This local differentiation of material properties enables simultaneous achievement of privacy protection and aesthetic display.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If registered cutting is used to create precise demarcation lines for wrapping, then manufacturing precision is improved, but process complexity and cost increase

Engineering Contradiction:
Improvewrapping precisionVSAvoidcutting process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The invention removes the requirement for registered cutting and demarcation lines from the manufacturing process. By designing the wrapper sheet to accommodate unregistered cutting, the complex registration system is extracted and eliminated, simplifying the overall manufacturing process.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using precise registered cutting to achieve proper wrapping alignment, the invention inverts the approach by designing the wrapper sheet pattern to remain coherent even when cut at arbitrary positions. The repeating pattern ensures that any cut position results in acceptable wrapping appearance.

Inventive Principle:
Principle #13The other way round (Inversion)

3Reliability

If individual wrapping is used to maintain hygiene and privacy, then product functionality is improved, but aesthetic continuity across multiple products is lost

Engineering Contradiction:
Improvehygiene and privacyVSAvoidaesthetic continuity
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The wrapper sheet features a repeating pattern of indicia that creates visual continuity when multiple individually wrapped products are stacked together. The periodic repetition of design elements across adjacent wrappers maintains aesthetic coherence while preserving individual wrapping benefits.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

Multiple individual wrapper sheets are designed to collectively form a unified visual composition when stacked. The indicia on adjacent wrappers are positioned and designed to work together, creating an integrated aesthetic effect that spans across individually packaged products.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A process for making individually wrapped personal hygiene absorbent articles is provided. It comprises: (i) providing a single image with indicia wherein at least one of the indicia is repeated more than once within said single image; (ii) printing a plurality of said single images over a continuous film to form a continuous repetition of the same single image in a side-by-side arrangement; (iii) cutting the printed film and/or web material along a transverse axis such to form a plurality of individual segments of film forming individual wrapping sheets comprising a portion of said single image and sized such to each accommodate one of said personal hygiene absorbent articles therein; (iv) wrapping individual personal hygiene absorbent articles each with one of said wrapping sheets such that a printed portion of the wrapping sheet is viewable; (v) stacking a plurality of the individually wrapped personal hygiene absorbent articles into a container.
