Phase-Shifted Wrapper Printing for Design Variety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging methods for personal care articles with multiple designs on individually wrapped items complicate manufacturing and make it difficult to indicate the opening location, leading to consumer confusion and increased time in usage.
Innovation Solution
A method of creating wrappers with multiple printed elements that repeat along a feedstock substrate, allowing for cutting out of phase to ensure only partial elements are on each wrapper, providing a clear indication of the opening location and enabling manufacturing on a single converting line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wrapper designs are manufactured on separate converting lines, then design variety and consumer discreetness are improved, but manufacturing complexity and device complexity increase
Solution Approach 1:
The patent merges multiple wrapper designs onto a single feedstock substrate that is processed on one converting line. Multiple wrapper designs are arranged in a sequence along the feedstock, allowing a single converting line to produce multiple different wrapper designs without requiring separate converting lines for each design, thus reducing manufacturing complexity while maintaining design variety
Solution Approach 2:
The patent segments the feedstock substrate into multiple wrapper portions, each containing a different wrapper design. The feedstock is divided into sequential sections with different printed elements, and the converting line processes each section to create individually wrapped articles with different designs, enabling design variety through segmentation rather than multiple converting lines
2Adaptability or versatility
If wrapper designs are configured with multiple printed elements, then consumer discreetness is improved, but difficulty in detecting opening location increases
Solution Approach 1:
The patent applies local quality by making the opening location distinct from the rest of the wrapper design. The opening location has a different printed element or visual characteristic compared to other areas of the wrapper, creating a local distinction that guides consumers to the opening without compromising the overall design variety or discreetness of the wrapper
3Adaptability or versatility
If multiple wrapper designs are printed on feedstock, then design variety is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-printing multiple wrapper designs onto the feedstock substrate before the converting line processes the wrappers. The different wrapper designs are printed in advance on the feedstock in a sequence, allowing the converting line to simply process the pre-designed wrappers without requiring high precision printing during the converting operation, thus reducing manufacturing precision requirements
