Solution Overview

Problem

Conventional electronic cigarettes often fail to replicate the taste experience of traditional cigarettes, and existing heating devices for cigarettes do not effectively address the release of carcinogenic ingredients during burning.

Innovation Solution

A heating device with a housing, heating chamber, and power supply, featuring heating pieces on opposite inner walls and a temperature-controlled system that heats the cigarette to form aerosol without burning, maintaining the integrity of the cigarette and enhancing taste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional electronic cigarettes heat tobacco liquid to form aerosol, then they provide an alternative to traditional cigarettes, but the taste experience is not as good as traditional cigarettes

Engineering Contradiction:

Improvecarcinogenic ingredients releaseVSAvoidtaste quality

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent changes the heating temperature parameter to a controlled range that prevents combustion (below ignition point) while maintaining effective aerosol generation. This temperature control resolves the contradiction by eliminating carcinogenic release from burning while preserving taste quality through proper heating conditions

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the chemical combustion process with an electrical heating system that uses heating pieces to generate heat electrically. This substitution eliminates the harmful chemical reactions of burning while maintaining the aerosol generation function, thereby removing carcinogenic ingredients without sacrificing taste

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Quantity of substance

If a heating device burns the cigarette to generate aerosol, then aerosol is formed, but carcinogenic ingredients are released

Engineering Contradiction:

Improveaerosol generationVSAvoidcarcinogenic ingredients

Core Design Contradiction:

Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent applies temperature parameter control to distinguish between heating (beneficial) and burning (harmful). By maintaining temperature below the ignition point of tobacco, the system generates sufficient aerosol while preventing the formation of carcinogenic ingredients that only occur at combustion temperatures

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent converts the harmful combustion process into a beneficial controlled heating process. By using electrical heating pieces to provide controlled thermal energy, the system achieves aerosol generation (benefit) without the harmful byproducts of burning, effectively turning a harmful process into a safe one

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Temperature

If the heating temperature is high enough to vaporize tobacco effectively, then aerosol is formed, but the cigarette burns and releases harmful substances

Engineering Contradiction:

Improveheating temperatureVSAvoidburning and carcinogenic release

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent precisely controls the temperature parameter within a specific range that is high enough for effective vaporization and aerosol formation but low enough to prevent combustion. This parameter optimization resolves the contradiction by finding the optimal temperature window that achieves the desired effect without harmful side effects

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent implements temperature monitoring and control mechanisms that provide feedback to maintain heating within safe limits. This feedback system ensures the temperature remains effective for aerosol generation while preventing it from rising to combustion levels, thereby eliminating harmful substances

Inventive Principle:

Principle #23Feedback
