Solution Overview
Problem
Companies face challenges in protecting their products and revenue streams from unauthorized use and counterfeiting, particularly in consumable products like cartridges, where competitors can bypass security features to use cheaper alternatives, leading to loss of investment and brand dilution.
Innovation Solution
A system that differentiates the spectral response of optical coatings using LED light signals to authenticate authorized products, ensuring only authorized cartridges can be used with specific dispensing apparatus by analyzing reflected light patterns and modifying dispenser activation accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security features are built into consumable products to prevent unauthorized use, then product authentication capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical or electronic security verification systems with an optical authentication system using LEDs and optical coatings. The consumable product contains an optical coating that interacts with specific wavelength LEDs in the dispensing apparatus, creating a simplified yet secure authentication mechanism that reduces overall system complexity while maintaining reliability.
Solution Approach 2:
The patent utilizes changes in optical parameters (wavelength, reflectivity, absorption) to create authentication mechanisms. By selecting specific LED wavelengths that interact differently with authorized versus unauthorized optical coatings, the system achieves reliable product verification through parameter differentiation rather than complex structural features.
2Reliability
If complex authentication codes are used in consumable products, then security against counterfeiting is improved, but ease of manufacture and cost worsen
Solution Approach 1:
The patent employs optical coatings with specific color properties that interact with LED light at different wavelengths. These coatings can be applied during normal manufacturing processes using conventional coating techniques, avoiding the need for complex code embedding while providing security through optical property differentiation that is difficult to replicate.
Solution Approach 2:
The patent applies thin-film optical coatings to disposable consumable products that can be manufactured at low cost using standard coating processes. The security feature is integrated into the coating itself rather than requiring separate authentication components, maintaining ease of manufacture while providing effective counterfeiting protection.
3Measurement precision
If spectral response analysis is used to differentiate authorized products, then measurement precision of authentication is improved, but device complexity increases
Solution Approach 1:
The patent uses periodic modulation of LED light sources at different wavelengths to analyze spectral responses. By alternating between specific wavelengths and measuring reflected or transmitted light, the system achieves precise authentication through temporal modulation rather than requiring complex simultaneous multi-wavelength analysis, thereby reducing device complexity while maintaining measurement precision.
