Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If quantum dot anti-counterfeit technology uses simple 1D or 2D barcode patterns, then the structure is simple and easy to manufacture, but it can only carry one function (either product information or security verification) simultaneously
Solution Approach 1:
The patent divides the anti-counterfeit label into multiple independent functional regions: a first pattern area containing quantum dots for security verification and a second pattern area containing traditional ink for product information. This segmentation allows each region to perform its specialized function while together they provide comprehensive anti-counterfeit capabilities with both security verification and information carrying functions.
Solution Approach 2:
The patent introduces a new dimension of functionality by using photoluminescent properties of quantum dots under specific light irradiation. Instead of relying solely on visual 2D patterns, the system adds the dimension of light interaction (absorption and emission characteristics) to create a dual-functional system that can simultaneously verify security and carry product information through different reading methods.
2Adaptability or versatility
If quantum dot anti-counterfeit technology uses complex multi-functional patterns, then it can carry both product information and security verification simultaneously, but the manufacturing complexity increases
Solution Approach 1:
The patent divides the anti-counterfeit label into multiple independent functional regions: a first pattern area containing quantum dots for security verification and a second pattern area containing traditional ink for product information. This segmentation allows each region to perform its specialized function while together they provide comprehensive anti-counterfeit capabilities with both security verification and information carrying functions.
Solution Approach 2:
The patent makes the quantum dot pattern area serve multiple purposes: it acts as both a security verification element (through photoluminescence characteristics) and an information carrier (through its spatial arrangement and response to different light conditions). This multi-functionality reduces the need for separate components and simplifies the overall manufacturing process.
3Reliability
If quantum dot anti-counterfeit labels use single-function patterns, then the manufacturing process is simple, but the security verification capability is limited
Solution Approach 1:
The patent divides the anti-counterfeit label into multiple independent functional regions: a first pattern area containing quantum dots for security verification and a second pattern area containing traditional ink for product information. This segmentation allows each region to perform its specialized function while together they provide comprehensive anti-counterfeit capabilities with both security verification and information carrying functions.
Solution Approach 2:
The patent applies different material properties to different regions: the first pattern area uses quantum dots with specific photoluminescence properties for high-reliability security verification, while the second pattern area uses traditional ink for information display. This local differentiation of material quality ensures each region optimizes its specific function, enhancing overall security verification reliability.
