Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no anti-counterfeiting measures are implemented, then device complexity is reduced, but reliability deteriorates due to inability to distinguish genuine from counterfeit products
Solution Approach 1:
The anti-counterfeiting system is segmented into distinct functional modules: an encryption chip embedded in the vaporizer containing unique identification code, and a microcontroller in the battery assembly for code verification. This segmentation allows the authenticity verification function to be added without redesigning the entire device, thus improving reliability while controlling complexity.
Solution Approach 2:
The encryption chip is pre-loaded with a unique anti-counterfeiting code during manufacturing, and the microcontroller is pre-programmed with verification algorithms and reference codes. This preliminary action ensures that authenticity verification is automatically performed upon connection, eliminating the need for additional user operations and maintaining system reliability without increasing operational complexity.
2Reliability
If static anti-counterfeiting codes are used, then manufacturing precision is improved through simple code embedding, but reliability deteriorates due to potential code copying by counterfeiters
Solution Approach 1:
The system transitions from static anti-counterfeiting codes to dynamic code generation. The microcontroller generates a new random anti-counterfeiting code each time the device is powered on or verified, and this code is temporarily stored in the encryption chip. This dynamic approach prevents code copying by counterfeiters since each verification cycle uses a different code, thereby improving reliability while the simple random number generation algorithm keeps manufacturing precision requirements manageable.
3Measurement precision
If encryption chip and microcontroller verification system is added, then product authenticity identification is improved, but device complexity increases due to additional components and circuit connections
Solution Approach 1:
The encryption chip serves multiple functions: storing the unique anti-counterfeiting identification code, receiving verification commands from the microcontroller, and providing authentication feedback. The microcontroller also performs dual roles as both the main control unit for the battery assembly and the verification unit for authenticity checking. This multi-functionality reduces the need for separate dedicated components, thereby improving measurement precision for authenticity identification while limiting the increase in device complexity.
