Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional luminescent taggants and color-shifting inks are used for anti-counterfeiting, then authentication capability is provided, but the security is easily replicated by counterfeiters
Solution Approach 1:
The patent combines fluoropolymer particles with luminescent pigments to create a composite luminescent composition. This composite structure provides enhanced security features that are difficult to replicate, as the combination of specific fluoropolymer particles and luminescent agents creates a unique authentication profile that counterfeiters cannot easily duplicate.
Solution Approach 2:
The patent utilizes specific luminescent agents that emit light at particular wavelengths when excited by UV radiation. By controlling the emission wavelength and intensity parameters of the luminescent composition, the patent creates authentication features that are difficult to replicate. The specific wavelength emission characteristics serve as a security parameter that counterfeiters cannot easily match.
2Reliability
If luminescent compositions are applied to packaging materials, then authenticity verification is enabled, but the complexity of the packaging system increases
Solution Approach 1:
The patent extracts the luminescent authentication function from complex multi-layer packaging systems and integrates it directly into the packaging material itself through the luminescent composition. This allows authenticity verification to be enabled while minimizing the addition of separate security components, thereby reducing overall system complexity.
Solution Approach 2:
The luminescent composition serves multiple functions: it provides aesthetic appearance, enables authenticity verification, and maintains compatibility with various packaging materials. By making the packaging material itself multi-functional, the patent reduces the need for separate security features, thereby reducing system complexity.
3Illumination intensity
If fluoropolymer particles are dispersed in liquid medium with luminescent agents, then color intensity is enhanced, but the manufacturing process complexity increases
Solution Approach 1:
The patent segments the luminescent composition into discrete fluoropolymer particles dispersed in a liquid medium containing luminescent agents. This segmentation allows for enhanced color intensity through proper particle size control and distribution, while the liquid medium formulation simplifies the manufacturing process by enabling easy mixing and application.
Solution Approach 2:
The patent optimizes parameters such as particle size, concentration, and dispersion uniformity to enhance color intensity. By controlling these parameters, the patent achieves enhanced luminescence while maintaining manufacturing simplicity through standard dispersion techniques and formulation methods.
