Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional magnetic card reading alone is used for authentication, then the device complexity is low, but the security reliability is insufficient
Solution Approach 1:
The patent combines multiple authentication methods (magnetic stripe reading, optical scanning, and radiation source imaging) into a single integrated card reading system. The card reading device includes a magnetic stripe reader, an optical scanner, and a radiation source, all working together to authenticate cards, thereby improving security without requiring multiple separate devices.
Solution Approach 2:
The card reading device is designed to perform multiple functions: reading magnetic stripe data, capturing optical images of the card, and detecting radiation characteristics. This multi-functional design allows a single device to provide comprehensive authentication, reducing the need for separate specialized devices while enhancing security.
2Measurement precision
If multiple authentication methods are implemented, then the authentication accuracy is improved, but the operation time increases
Solution Approach 1:
The patent implements continuous authentication where the optical scanner and radiation source operate continuously or in rapid succession during the card reading process. The magnetic stripe reading, optical imaging, and radiation detection occur in an integrated timeline, minimizing gaps between authentication steps and reducing total authentication time while maintaining high accuracy.
Solution Approach 2:
The system performs preliminary authentication actions automatically as the card is inserted and read. The optical scanner captures images and the radiation source detects characteristics immediately upon card insertion, before the user completes any manual input, thereby reducing the perceived authentication time while maintaining thorough verification.
3Adaptability or versatility
If optical scanning and radiation sources are added to the card reader, then the authentication capability is enhanced, but the device complexity increases
Solution Approach 1:
The optical scanner, radiation source, and magnetic stripe reader are merged into a single card reading device housing. This integration allows all authentication components to share common structural elements, control systems, and physical spaces, thereby enhancing authentication capability while minimizing the increase in overall device complexity compared to having separate devices.
