Embossed Layer Segmentation for Optical Structure Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When two images with different optical principles and uneven structure sizes are placed close to each other, their reflections intertwine, causing the display images to mix and become indistinguishable, leading to difficulties in recognizing the images. Additionally, combining wave optical and geometric optical structures on the same surface can result in deformation or fracture of the uneven structures.
Innovation Solution
A display body with an embossed layer that includes a geometric optical structure region, a wave optical structure region, and a third structure region. The third structure region is located between the other two regions and has a specific height and width configuration to prevent the intertwining of reflections and to ensure the structural integrity of the uneven structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wave optical structure and geometric optical structure are arranged in divided regions on the same flat surface, then counterfeit prevention effect is improved, but the uneven structures may be deformed or fractured
Solution Approach 1:
The label is divided into multiple divided regions, with each region containing either wave optical structure or geometric optical structure. This spatial segmentation prevents the two different optical structures from being in direct contact, thereby avoiding mutual deformation while maintaining the counterfeit prevention effect through diverse optical displays in different regions.
Solution Approach 2:
A transparent or translucent resin layer is introduced as an intermediary between the wave optical structure and geometric optical structure. This intermediate layer physically separates the two structures, preventing direct contact and potential deformation/fracture, while still allowing the optical structures to function effectively in their respective divided regions.
2Adaptability or versatility
If two images with different optical principles are placed close to each other, then the display image diversity is improved, but the reflections intertwine and the images become indistinguishable
Solution Approach 1:
The label surface is segmented into multiple divided regions, with each region dedicated to displaying a specific optical image (wave optical or geometric optical). This spatial segmentation ensures that reflections from different optical structures do not intertwine, maintaining clear and distinguishable images while achieving display diversity through the combination of different optical principles in different regions.
