Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual inspection method is used for identity recognition, then the identification card structure remains simple and cost-effective, but security is inadequate and recognition precision is low due to ease of counterfeiting and human error
Solution Approach 1:
The patent changes the physical state of the card by incorporating a sensor film that generates electrical responses when touched or compressed. This transforms the card from a purely visual static object to an interactive device with dynamic electrical characteristics, enhancing security without requiring complex electronic components
Solution Approach 2:
The patent replaces the mechanical visual inspection system with an electrical detection system. Instead of relying on human visual judgment, the system uses electrical signals to detect and verify card characteristics, improving both security and recognition precision
2Measurement precision
If digital recording technology (IC card or proximity card) is used, then recognition speed and precision are improved and counterfeiting is prevented, but the cost increases due to expensive readers and electronic sensor technologies
Solution Approach 1:
The patent uses a relatively simple sensor film instead of expensive IC chips or proximity card technologies. The sensor film provides sufficient security and recognition capabilities at a lower cost, making the identification card more affordable and accessible while maintaining adequate functionality
Solution Approach 2:
The patent changes the detection method from requiring expensive electronic readers to using simpler electrical response detection. By transforming the card into an inductive device that generates detectable electrical signals through touch or compression, it reduces the need for costly reading equipment
3Productivity
If visual recognition by inspector is used, then no additional equipment is needed, but recognition time increases and error rate increases when huge crowds swarm simultaneously
Solution Approach 1:
The patent enables the card to provide its own verification signals through the sensor film's electrical responses. When touched or compressed, the card automatically generates detectable signals that verify its authenticity, eliminating the need for time-consuming manual inspection by inspectors
Solution Approach 2:
The patent replaces the manual visual recognition process with an automated electrical detection system. The sensor film's electrical responses provide objective verification signals that can be quickly processed, improving both recognition speed and accuracy even when handling large crowds
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced security and accuracy in identity recognition, preventing counterfeiting while being more affordable and accessible, as it uses a sensor film to differentiate authentic from fake cards through unique electrical responses.
Implementation Method 1
sensor points which are distributed on its exterior and which are touched or compressed to change the sensor points' electrical responses
Implementation Method 2
blocking points on the sensor film which change electrical responses of the local sensor points beforehand, so that different response signals corresponding to detective signals which are applied to the sensor film are generated by the blocking points
Data Source
AI summary
An inductive identification card on which a card holder's identifying information is recorded in order to recognize the holder's identity via a visual inspection. The identification card is provided with a sensor film on the surface having sensor points which are distributed on its exterior, blocking points corresponding to the identifying information on the identification card, and locally changing electrical responses of sensor points in advance so that different response signals corresponding to detective signals which are applied to the sensor film are generated by the blocking points and peripheral regions, respectively. Authenticity of the identification card and the card holder's identity are recognized by determining locations of response signals.
