Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-forgery systems are vulnerable to duplication and copying due to mass production and known technologies, lacking a simple and reliable method for unique product marking that can be easily identified.
Innovation Solution
A unique marking system using microencapsulated color drops mixed with micronized microparticles in a basic vehicle, which break up under pressure to form random, unrepeatable patterns during printing, creating a distinctive and irreproducible background map.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing anti-forgery systems are used, then identification capability is provided, but vulnerability to duplication and copying occurs
Solution Approach 1:
The patent applies preliminary action by pre-mixing microencapsulated color drops with micronized microparticles in a basic vehicle to create an ink composition before printing. This pre-prepared mixture ensures that when printed under pressure, the microcapsules break up to form random, unrepeatable patterns immediately, providing inherent anti-forgery protection without requiring subsequent complex verification processes.
Solution Approach 2:
The patent utilizes parameter changes by controlling the pressure applied during printing to cause the microencapsulated color drops to break up. The specific pressure parameter transforms the intact microcapsules into fragmented patterns with random size and distribution, creating unique markings that cannot be reproduced. This parameter change is critical for generating the unrepeatable background map.
2Reliability
If complex anti-forgery systems are implemented, then security level is improved, but system complexity and cost increase
Solution Approach 1:
The patent applies self-service by designing a system where the marking process automatically generates unique, unrepeatable patterns through the physical breaking up of microencapsulated drops during printing. The system serves itself by using the inherent randomness of the breaking process to create security features without requiring additional complex equipment or post-processing steps to generate uniqueness.
Solution Approach 2:
The patent employs cheap short-living objects by using microencapsulated color drops that are designed to break up during the printing process. These microcapsules are consumed in the marking process, creating a unique pattern that cannot be reproduced. The simplicity and low cost of the ink composition materials contribute to an economically viable anti-forgery solution.
3Reliability
If unique marking is achieved through random patterns, then unrepeatability is improved, but detection difficulty increases
Solution Approach 1:
The patent applies color changes by using microencapsulated color drops that release their pigment when broken up during printing. The color provides visual contrast against the background, making the random patterns created by the broken microcapsules easily detectable and distinguishable. This color mechanism simplifies detection while maintaining unrepeatability.
Solution Approach 2:
The patent uses parameter changes in the size and distribution of the broken microcapsule fragments to create detectable variations. The random fragmentation produces particles of different sizes scattered in unique patterns, which can be detected and measured to verify authenticity. The parameter variations in fragment size provide detectable features without compromising unrepeatability.
