Solution Overview

Problem

Aerosol generating devices accidentally activate due to collisions during transportation, leading to energy waste and safety hazards.

Innovation Solution

Implement a control method that counts the number of cigarette lighting signals within a preset duration and switches the device to an operating state only when the condition is met, disconnecting power supply in standby mode to conserve energy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the device uses a simple cigarette lighting button that can be directly triggered by external force, then the ease of operation is improved, but the reliability deteriorates due to accidental activation during transportation

Engineering Contradiction:
Improveease of lightingVSAvoidactivation accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The control device performs preliminary counting of lighting signals within a preset time window before activating the atomizing device. This preliminary action distinguishes between accidental single triggers and intentional multiple triggers, preventing false activation while maintaining ease of use.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control device acts as an intermediary between the cigarette lighting button and the atomizing device startup. It intercepts and analyzes multiple lighting signals, using the signal count as a mediator to determine whether activation should occur, thereby preventing accidental triggers.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If the device continuously powers the central processor to ensure immediate response to lighting signals, then the response speed is improved, but the energy consumption increases

Engineering Contradiction:
Improveresponse speedVSAvoidenergy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The control device uses periodic sampling of lighting signals within a preset time window instead of continuous monitoring. This periodic action reduces energy consumption while still enabling fast response to intentional multiple lighting triggers.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The control device monitors its own operating state and automatically adjusts power supply based on detected lighting signal patterns. When accidental activation is detected, it automatically cuts off power to prevent energy waste, making the system self-regulating.

Inventive Principle:
Principle #25Self-service

3Productivity

If the device activates immediately upon receiving a single lighting signal, then the productivity is improved, but the loss of energy increases due to unnecessary atomizer activation

Engineering Contradiction:
Improvelighting response efficiencyVSAvoidenergy waste
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The system performs preliminary verification by counting lighting signals within a preset time window before committing to atomizer activation. This preliminary check ensures that only intentional multiple triggers result in activation, preventing energy waste from accidental single triggers.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control device implements feedback by monitoring the number of lighting signals received and using this information to determine whether to activate the atomizing device. The feedback loop prevents energy waste by requiring multiple signals within a time window, confirming user intent before consuming energy.

Inventive Principle:
Principle #23Feedback

AI summary

An aerosol generating device control method and device, relating to the field of aerosol generating device control, and aiming to solve the problem that inefficient energy consumption is caused when accidental activation occurs in an aerosol generating device during transportation due to collision with other articles in a same space. The aerosol generating device control method comprises: acquiring activation signals (101); collecting statistics about current frequency information of the acquired activation signals within a first preset duration (102); and when the current frequency information satisfies a preset frequency condition, switching from a standby state to a working state (103). When in use, an aerosol generating device can enter a normal working state when the frequency of activation within the first preset duration satisfies the frequency condition; the default state is a standby state, such that efficient utilization of energy of a battery cell in the aerosol generating device is ensured.
