Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the atomizer and power device are in detachable connection to enable different models or brands to be used together, then the adaptability and versatility are improved, but the reliability deteriorates due to confusion and errors in electronic cigarette functions
Solution Approach 1:
The patent applies preliminary action by performing identity authentication before the atomizer and power device can work together. The control unit generates a challenge code that is authenticated against the atomizer's identity information stored in the encryption authentication unit. This pre-authentication step ensures that only compatible and authorized combinations can operate, preventing functional confusion and errors while maintaining the detachable connection capability for different models and brands.
2Reliability
If identity authentication is implemented between atomizer and power device to prevent mixed use, then the reliability is improved, but the device complexity increases due to additional encryption authentication units and control mechanisms
Solution Approach 1:
The patent applies segmentation by dividing the authentication system into distinct functional components: an encryption authentication unit in the atomizer that stores identity information, and a control unit in the power device that generates challenge codes and verifies authentication. This segmentation allows the authentication functionality to be distributed across separate components, making the system modular and manageable despite the added complexity. Each component has a specific role, reducing the overall system complexity through clear functional division.
3Reliability
If encryption authentication is performed using challenge-response mechanism, then the security and reliability are improved, but the time consumption increases due to additional calculation and communication steps
Solution Approach 1:
The patent applies partial action by implementing a challenge-response authentication mechanism that performs only the necessary minimum calculations required for security verification. The control unit generates a challenge code and the encryption authentication unit computes the response using pre-stored identity information and encryption algorithms. This approach performs just enough authentication steps to ensure security without unnecessary additional calculations, thereby minimizing time consumption while maintaining authentication security.

AI summary
An electronic cigarette (100) control method and an electronic cigarette (100). The electronic cigarette (100) includes an atomizer (10) and a power device (20), the atomizer (10) is provided with an encryption authentication unit (11), the power device (20) is provided with a control unit (21), and when the atomizer (10) is connected to the power device (20), the encryption authentication unit (11) is in communication connection with the control unit (21); the electronic cigarette (100) control method includes: generating a first identity authentication code (S100); acquiring a second identity authentication code from the encryption authentication unit (11) (S120); performing identity authentication according to the first identity authentication code and the second identity authentication code (S130); controlling the electronic cigarette (100) to activate if the identity authentication is passed (S150a); and prohibiting the electronic cigarette (100) to activate if the identity authentication is not passed (S150b). The above method is capable of effectively preventing the mixed use of the atomizer and the power device, thereby improving the user experience.
