Solution Overview

Problem

Conventional flavor cartridges/cigarettes experience low nicotine release and significant attenuation, leading to poor taste and user experience due to inadequate heating methods.

Innovation Solution

A heating control method that adjusts the heating temperature of a heating body in a stepwise manner based on inhalation parameters, such as inhalation time or duration, to optimize nicotine and substance release, using a ΔT1=(U*I*t−Qdissipation)/(M*C) relation to adjust heating parameters like voltage, current, or time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the heating temperature is kept constant or low, then the device operates safely and avoids burning, but the nicotine release amount is low and attenuates significantly

Engineering Contradiction:

Improvenicotine release amountVSAvoidheating temperature

Core Design Contradiction:

Quantity of substanceVSTemperature

Solution Approach 1:

The heating temperature is changed from a static constant value to a dynamic variable that adjusts in real-time based on inhalation parameters. The control system dynamically modifies the heating temperature in a stepwise manner according to the user's inhalation characteristics, ensuring optimal nicotine release at different stages of inhalation without causing burning.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The heating temperature parameter is changed progressively in a stepwise manner based on inhalation parameters. By changing the temperature parameter dynamically rather than keeping it fixed, the system achieves both sufficient nicotine release and prevention of burning, resolving the contradiction between quantity of substance release and temperature control.

Inventive Principle:

Principle #35Parameter changes

2Quantity of substance

If the heating temperature is increased to improve nicotine release, then the nicotine release amount increases, but the taste deteriorates and user experience worsens due to burning

Engineering Contradiction:

Improvenicotine release amountVSAvoidburning and taste deterioration

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The heating temperature is dynamically adjusted based on real-time inhalation parameters rather than maintained at a fixed high temperature. This dynamic control ensures that the temperature is sufficient to release nicotine effectively while preventing excessive heating that would cause burning and taste deterioration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The control system uses feedback from inhalation parameters to adjust the heating temperature appropriately. By monitoring inhalation characteristics and adjusting the heating temperature in response, the system achieves optimal nicotine release without causing burning, as the temperature is tailored to the actual usage conditions rather than being constantly high.

Inventive Principle:

Principle #23Feedback

3Quantity of substance

If a single heating temperature is used throughout inhalation, then the device is simple to control, but the nicotine release attenuates significantly as inhalation progresses

Engineering Contradiction:

Improvenicotine release consistencyVSAvoidheating control complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The heating temperature is changed from a static single value to a dynamic multi-stage control strategy. The temperature is adjusted in a stepwise manner according to inhalation parameters, allowing the system to maintain consistent nicotine release throughout the inhalation process while managing complexity through structured temperature stages.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The heating control is segmented into multiple temperature stages rather than using a single temperature throughout. By dividing the heating control into distinct temperature levels that correspond to different inhalation stages, the system achieves consistent nicotine release while maintaining manageable complexity through structured segmentation.

Inventive Principle:

Principle #1Segmentation
