Laser Edible Marking Pattern With Index Dots for Anti-Counterfeiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edible body marking technologies, such as two-dimensional data codes, can be difficult for consumers to understand and do not effectively prevent counterfeit drugs, as they can be easily replicated using general reading devices.
Innovation Solution
A laser-marked edible body marking system that forms a marking pattern with positional information of index dots added or removed from a basic pattern, allowing for additional information to be encoded in a way that is visually recognizable to consumers without discomfort, while also making counterfeiting difficult due to the unique positional information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a two-dimensional data code is used to record multiple pieces of information on the drug surface, then the information capacity is improved, but the consumer understanding and comfort deteriorate because it displays a mechanical pattern that is difficult for consumers to understand
Solution Approach 1:
The marking pattern is segmented into a basic pattern (visually recognizable characters, numbers, or figures) and additional information (encoded through positional information of index dots). This segmentation allows the basic pattern to convey information in an easily understandable format while the index dots encode additional data, thereby resolving the contradiction between information capacity and consumer understanding.
Solution Approach 2:
The patent adds another dimension of information encoding by using the positional information of index dots relative to the basic pattern. This additional spatial dimension allows encoding of extra information without compromising the visual recognizability of the basic pattern, thus increasing information capacity while maintaining consumer understanding.
2Ease of operation
If a general two-dimensional code is used that can be easily read by general-use reading devices, then the reading convenience is improved, but the counterfeit prevention capability deteriorates because anyone can easily grasp the information
Solution Approach 1:
The patent applies local quality by making only specific parts of the marking pattern (the index dots) encode additional information through their positional relationships, while the basic pattern remains visually recognizable. This localized encoding approach allows standard reading devices to read the basic pattern conveniently while requiring specialized processing to decode the positional information of index dots, thereby providing counterfeit prevention without sacrificing reading convenience.
3Loss of information
If index dots are added or removed from a basic pattern to encode additional information, then the information capacity is improved, but the manufacturing complexity increases due to the need for precise laser spot positioning and deformation control
Solution Approach 1:
The patent replaces complex mechanical positioning systems with a laser-based marking system that uses optical fields to create and position index dots. The laser spot can be precisely controlled in position, size, and shape through optical parameters, simplifying the manufacturing process while enabling accurate encoding of additional information through index dot positioning relative to the basic pattern.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively conveys multiple pieces of information without causing consumer discomfort and enhances counterfeiting prevention by making it difficult for third parties to replicate the marking patterns accurately.
Implementation Method 1
forms a marking pattern on an edible body by scanning a laser spot, wherein the marking pattern includes, as additional information, positional information of one or more index dots that are made by partially deforming or removing one or more dots of the laser spot

AI summary
An edible body marking device that forms a marking pattern on an edible body by scanning a laser spot. The marking pattern includes, as additional information, positional information of one or more index dots that are made by partially deforming or removing one or more dots of the laser spot, or newly adding one or more dots of the laser spot with respect to a basic pattern that is obtained by forming a plurality of the dots of the laser spot.
