Single-Wire Cartridge Authentication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic cigarettes cannot effectively recognize and authenticate cartridges, leading to inconsistent quality and user experience due to the inability to verify anti-counterfeiting information.
Innovation Solution
An information reading system and method utilizing a control module with signal pins to establish single-wire paths for power supply and data communication, allowing for automatic reading of anti-counterfeiting information stored in cartridges, with the ability to switch connection modes if initial attempts fail.

Engineering Contradiction Analysis
1Productivity
If traditional multi-wire communication protocols are used for reading cartridge information, then communication reliability may be maintained, but information reading speed is slow and system complexity increases
Solution Approach 1:
The patent combines power supply and data communication functions into a single wire path. The single-wire path simultaneously carries both power and data signals between the tobacco rod and cartridge, eliminating the need for separate power and data connections. This merging of functions directly achieves faster information reading while reducing connection complexity.
Solution Approach 2:
The single wire path is designed to perform multiple functions: it serves as both a power supply conductor and a data communication channel. This multi-functional design allows the same physical connection to handle both energy transfer and information exchange, improving reading speed while simplifying the overall system architecture.
2Reliability
If cartridge authentication is not implemented, then device simplicity is maintained, but quality supervision and user experience deteriorate
Solution Approach 1:
The system performs authentication reading automatically as soon as the cartridge is inserted into the tobacco rod, before the user activates the device. The control module initiates the single-wire communication to read anti-counterfeiting information immediately upon detection of cartridge insertion, ensuring quality verification happens proactively without requiring additional user actions or complex authentication interfaces.
Solution Approach 2:
The authentication process is fully automated through the control module, which autonomously manages the single-wire communication protocol to read and verify cartridge information. The system self-performs the quality supervision function without requiring external authentication mechanisms or complex verification procedures, maintaining reliability while minimizing added complexity.

AI summary
An information reading system includes an information reading device and a device-to-be-identified. The information reading device includes a first signal pin, a second signal pin, and a control module, and the device-to-be-identified includes a third signal pin and a ground pin. The control module is configured to, when recognizing that the device-to-be-identified is inserted, control the first signal pin to connect to the third signal pin of the device-to-be-identified, and control the second signal pin to connect to the ground pin, to form a first single-wire path, and attempt to read anti-counterfeiting information stored in the device-to-be-identified by using the first single-wire path.
