Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If heating is used to vaporize e-liquid, then aerosol production is achieved, but harmful byproducts such as propylene glycol polymers and carbonyls are generated

Engineering Contradiction:

Improveaerosol productionVSAvoidharmful byproducts

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the thermal field (heating element) with a mechanical field (vibrating mesh assembly). The mesh assembly vibrates at high frequency to atomize the liquid directly without heating, thereby producing aerosol while avoiding the formation of thermal decomposition byproducts such as carbonyls and propylene glycol polymers.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention changes the operating parameters from high temperature (heating to vaporization) to high frequency mechanical vibration. This parameter change allows liquid atomization to occur at ambient or near-ambient temperatures, eliminating the harmful chemical reactions that occur during thermal vaporization.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If conventional heating vaporization is used, then aerosol is produced, but active ingredient delivery is reduced due to body filtration processes

Engineering Contradiction:

Improveactive ingredient deliveryVSAvoidefficacy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent changes the aerosol generation mechanism from thermal vaporization to mechanical atomization, producing smaller and more uniform particle sizes. This results in deeper lung penetration and bypasses the body's filtration processes, thereby improving the reliability and efficacy of active ingredient delivery.

Inventive Principle:

3Ease of operation

If heating element is used to convert liquid to aerosol, then vaporization occurs, but carcinogenic substances are inhaled

Engineering Contradiction:

Improvevaporization processVSAvoidcarcinogen inhalation

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes the thermal conversion process with a mechanical atomization process. The vibrating mesh assembly mechanically breaks liquid into fine droplets that form aerosol, eliminating the need for heating and thereby preventing the formation and inhalation of carcinogenic substances.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention converts the harmful effect of heating (which causes carcinogen formation) into a beneficial mechanical process. By using high-frequency vibration instead of heat, the system achieves aerosol generation while eliminating the harmful thermal decomposition reactions.
