Solution Overview

Problem

Existing electronic atomizing devices face challenges in efficiently controlling the temperature of the heating body, leading to reduced service life and contaminated aerosol quality due to the direct contact of the heating body with tobacco materials, which affects the taste and requires frequent replacement.

Innovation Solution

The electronic atomizing device incorporates a heating assembly with a memory chip storing the correspondence between resistance and temperature, allowing the main body to control the heating body's temperature based on real-time resistance and working-time information, enabling precise temperature management and facilitating easy replacement of the heating assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the heating body directly contacts tobacco materials for heating, then the heating function is achieved, but the aerosol quality becomes contaminated and taste deteriorates

Engineering Contradiction:
Improveaerosol qualityVSAvoidcontamination
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The heating system is segmented into separate functional components: a heating body for temperature control and a heating chamber for holding tobacco materials. This separation prevents direct contact between the heating body and tobacco, eliminating contamination while maintaining heating functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A heating chamber acts as an intermediary between the heating body and tobacco materials. The heating body heats the chamber, which in turn heats the tobacco materials indirectly, preventing direct contact and contamination of the aerosol.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Power

If the heating body operates at high temperature for extended periods, then the heating function is maintained, but the service life is reduced and replacement frequency increases

Engineering Contradiction:
Improveheating capabilityVSAvoidservice life
Core Design Contradiction:
PowerVSDuration of action of moving object

Solution Approach 1:

The heating body temperature is dynamically controlled based on real-time resistance monitoring. The controlling assembly adjusts heating power to maintain optimal temperature within a safe range, preventing excessive heat damage and extending service life while maintaining effective heating capability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A feedback control system continuously monitors the resistance of the heating body and adjusts heating power accordingly. This closed-loop control prevents temperature excursions that would reduce service life, while maintaining sufficient heating power for effective atomization.

Inventive Principle:
Principle #23Feedback

3Reliability

If the heating body temperature is not precisely controlled, then the device structure is simpler, but the taste quality and aerosol purity deteriorate

Engineering Contradiction:
Improvetaste qualityVSAvoidtemperature control system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The controlling assembly monitors heating body resistance in real-time and adjusts heating power to maintain precise temperature control. This feedback mechanism ensures consistent taste quality and aerosol purity without requiring overly complex control systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces complex mechanical temperature sensing and control mechanisms with an electrical resistance-based control system. The heating body's resistance serves as a proxy for temperature, simplifying the control system while maintaining precise temperature regulation for optimal taste quality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
