Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security features are implemented in consumable products, 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 detection system. The dispenser uses optical sensors to detect specific optical properties (such as reflectivity, absorption, or fluorescence characteristics) of the cartridge's optical coating, thereby authenticating the product without complex mechanical interfaces or electronic communication protocols.
Solution Approach 2:
The patent utilizes optical coatings with specific optical properties that interact with light in characteristic ways. The detection system shines light on the cartridge and measures the reflected, absorbed, or emitted light properties. Authorized cartridges have optical coatings engineered to produce specific optical responses, allowing authentication through optical property detection rather than complex security protocols.
2Reliability
If sophisticated authentication systems are used, then unauthorized product detection is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces sophisticated electronic authentication systems with simpler optical detection. The optical coating can be applied during standard manufacturing processes, and the detection system uses optical sensors rather than complex electronic verification mechanisms, reducing overall manufacturing costs while maintaining detection accuracy.
Solution Approach 2:
The patent changes the authentication approach from verifying complex electronic parameters or mechanical features to measuring optical parameters such as reflectivity, absorption, or fluorescence. This parameter change allows authentication to be integrated into existing manufacturing workflows and reduces the cost of both the authentication feature and the verification system.
3Reliability
If optical authentication systems are implemented, then product pairing security is improved, but ease of operation decreases
Solution Approach 1:
The patent implements an automatic optical authentication system where the dispenser independently verifies the cartridge's optical properties upon insertion. The system performs the authentication without requiring user intervention, such as entering codes or following verification steps, thereby maintaining ease of operation while ensuring security.
Solution Approach 2:
The patent replaces manual authentication procedures with automatic optical detection. The optical sensor system automatically detects the optical properties of the cartridge and determines authenticity without user involvement, eliminating the need for users to perform complex operations while maintaining high security standards.
