Solution Overview

Problem

The prevalence of e-cigarettes among minors poses health and societal risks due to improper usage and excessive consumption, necessitating a preventive measure to restrict access.

Innovation Solution

A method and device for e-cigarette child lock that detects and analyzes inhalation parameters such as duration, suction force, and pulse width intervals to generate unlock or lock signals based on preset conditions, increasing the difficulty of use for minors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If simple lock mechanisms are used, then ease of operation is improved, but security against minors deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies parameter changes by monitoring multiple inhalation parameters (duration, interval, strength) simultaneously and comparing them against preset thresholds. The control unit generates unlock signals only when all parameters meet their respective conditions, transforming a simple lock into a multi-parameter verification system that maintains ease of operation while significantly improving security against minor misuse.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If multiple parameters are monitored, then security is improved, but device complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements universality by having the control unit perform multiple functions: it monitors inhalation parameters, compares them against preset conditions, determines whether to generate unlock signals, and controls the execution unit accordingly. This multi-functional approach allows the system to achieve high security through multiple parameter monitoring while avoiding the need for separate dedicated components for each function, thereby limiting the increase in device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

This present application relates to a method and device for accomplishing child lock of e-cigarette, storage medium, e-cigarette. The method includes the following steps: Step S10: Detecting a total duration T of an action with three consecutive inhalations, a suction force P of each inhalation action in an action with three consecutive inhalations, a pulse width S of each inhalation pulse in an action with three consecutive inhalations, and a pulse width interval G between adjacent inhalation pulses in an action with three consecutive inhalations; Step S20: Determining whether the total duration T, the suction force P of any single suction, the pulse width S of any single suction, and the pulse width interval G between adjacent suction pulses simultaneously meet their preset conditions; Step S30: Generating an unlock signal or a lock signal when the above-mentioned suction action parameters T, P, S and G meet their preset conditions. The method for implementing a child lock in this invention increases the difficulty of unlocking or locking the e-cigarette and better aligns with adult usage habits, thereby avoiding safety hazards caused by minors' misusing the e-cigarette.
