Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication methods are used, then the authentication system is simple, but the anti-counterfeit property is insufficient
Solution Approach 1:
The patent employs thermosensitive recording media that change color or optical properties in response to thermal stimuli. This allows the card to display different visual states under different conditions, providing an intuitive anti-counterfeit mechanism that does not require complex electronic components or authentication systems.
Solution Approach 2:
The invention utilizes changes in physical parameters (such as optical properties, color, or thermal response) of the thermosensitive recording medium to encode authentication information. These parameter changes provide verifiable anti-counterfeit characteristics while maintaining system simplicity, as the changes can be detected by basic optical or thermal sensors rather than complex verification systems.
2Reliability
If thermosensitive recording medium with unique physical features is added, then anti-counterfeit protection is improved, but device complexity increases
Solution Approach 1:
The thermosensitive recording medium serves multiple functions simultaneously: it acts as both the authentication element with unique physical features and the information storage medium. This multi-functionality reduces overall device complexity by eliminating the need for separate components for authentication and data storage.
Solution Approach 2:
The patent uses composite thermosensitive recording media that integrate multiple functional layers or materials with different properties. These composite structures provide unique physical features for authentication while maintaining a relatively simple overall structure that can be manufactured as a single integrated component.
