Electronic-Cigarette Cartridge Authentication via Frequency Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing processes for electronic-cigarette cartridges with authentication chips are complex and difficult to meet production requirements, particularly in ensuring anti-counterfeiting authentication with minimal processing and manufacturing complexity.
Innovation Solution
An electronic-cigarette cartridge design featuring a first and second contact point connected to the base part, an authentication module operating at a high frequency, and a heating module operating at a low frequency, with the authentication module interacting with the base part to perform anti-counterfeiting authentication without affecting the heating module, thereby reducing complexity and ensuring performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an authentication chip is installed in the cartridge to conduct anti-counterfeiting authentication, then the reliability of the cartridge is improved, but the device complexity and manufacturing complexity increase
Solution Approach 1:
The patent merges the authentication module and heating module into a single cartridge structure that shares common components (contact points, power supply, control circuitry). The authentication chip and heating element are integrated within the same cartridge housing, allowing both functions to coexist with minimal additional complexity. The base part contains the main control chip that manages both authentication and heating operations, further reducing overall system complexity.
Solution Approach 2:
The cartridge is designed to serve multiple functions: it contains both the authentication module for anti-counterfeiting verification and the heating module for vaporization. The same contact points and power supply circuitry serve both authentication and heating operations. This multi-functionality reduces the need for separate dedicated components and simplifies the overall device architecture.
2Device complexity
If the authentication module and heating module operate at the same frequency, then the device complexity is reduced, but the reliability deteriorates due to mutual interference
Solution Approach 1:
The patent applies different operating frequencies to different functional modules within the cartridge: the authentication module operates at a high frequency (e.g., RF range for wireless communication or high-frequency AC for capacitive coupling), while the heating module operates at a low frequency (e.g., 50/60 Hz or low-frequency PWM). This frequency differentiation ensures that the electromagnetic fields generated by each module do not interfere with the other, maintaining reliable operation of both functions simultaneously.
