Container Substrate Pattern Segmentation for High-Visibility Markings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming images and figures on containers, such as PET bottles, result in decreased visibility due to the visibility of the image or figure being compromised.
Innovation Solution
A substrate with a first pattern formed by an aggregate of second patterns, where the second patterns are smaller than the first pattern, increasing the diffusive property and contrast of the first pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a pattern is formed directly on the container surface using laser, then labelless container is achieved and recycling is facilitated, but the visibility of the image or figure decreases
Solution Approach 1:
The first pattern is segmented into multiple second patterns that are arranged in an aggregate. Each second pattern is a smaller element, and their collective arrangement forms the larger first pattern. This segmentation allows light to interact with multiple small structures rather than a single large pattern, enhancing light diffusion and scattering properties, thereby improving visibility while maintaining the laser-formed labelless container benefits
Solution Approach 2:
The patent applies different structural qualities at different scales: the first pattern provides the overall information display, while the second patterns provide local light-diffusing structures. By making the second patterns smaller and arranging them in aggregates, the local optical properties are enhanced to improve visibility without compromising the global function of information display and recycling facilitation
