Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarettes lack effective mechanisms to prevent juvenile use, as they do not provide adequate encryption or personal customization options.
Innovation Solution
An electronic cigarette with an electronic child lock that utilizes NFC technology to power on the device only after a valid login through a mobile device, featuring a microcontroller, NFC chip, and application program for secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing electronic cigarettes are used without encryption, then ease of operation is improved, but reliability of preventing juvenile use deteriorates
Solution Approach 1:
The system performs preliminary authentication actions before allowing operation. The NFC chip stores authentication data in advance, and the mobile device verifies user identity through login before enabling the electronic cigarette, preventing unauthorized juvenile access while maintaining smooth operation for authorized users
Solution Approach 2:
The patent introduces an intermediary authentication system between the user and the electronic cigarette. The mobile device with NFC functionality acts as a mediator that verifies user identity and communicates with the electronic cigarette's NFC chip, adding a reliable security layer without complicating the actual device operation
2Reliability
If NFC authentication system is added, then reliability of preventing juvenile use is improved, but device complexity increases
Solution Approach 1:
The authentication system is segmented into separate functional modules: the NFC chip embedded in the electronic cigarette handles storage and basic communication, while the mobile device's electronic cigarette application program handles the complex authentication logic and user interface, distributing complexity across multiple components
Solution Approach 2:
The system utilizes the mobile device's existing NFC hardware and processing capabilities to perform authentication functions. The electronic cigarette itself remains relatively simple, relying on the user's smartphone to provide the complex authentication services, thereby avoiding significant increases in the electronic cigarette's device complexity
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

AI summary
The disclosure provides an electronic cigarette having an electronic child lock and a control method thereof. The electronic cigarette comprises a vaporizer, a battery assembly, and an electronic child lock for controlling power-on and power-off of the electronic cigarette. The battery assembly comprises a battery and a control circuit board. The electronic child lock comprises a microcontroller, a switching circuit, a readable and writable NFC chip, and an NFC antenna, which are arranged on the control circuit board, and comprises a mobile device having NFC function and installed with an electronic cigarette application program. The application program reads the power-on password preset in the NFC chip and compares it with the power-on password preset in the electronic cigarette application program. If the power-on password is correct, the microcontroller controls switching on of the switching circuit to perform power-on operation such that the electronic cigarette enters the standby state.
