Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If heating elements like coils are used to vaporize e-liquid, then vaporization function is achieved, but leakage, overheating, and health risks occur

Engineering Contradiction:

Improvevaporization reliabilityVSAvoidleakage and overheating

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the thermal heating mechanism (coils) with an ultrasonic vibration mechanism. The ultrasonic transducer generates high-frequency mechanical vibrations that atomize the e-liquid through cavitation and mechanical energy, eliminating the need for direct heat application and thereby preventing overheating and associated harmful effects

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent utilizes ultrasonic-induced phase transition of liquid to aerosol. The ultrasonic vibrations cause the liquid to undergo phase change from liquid droplets to fine aerosol particles through cavitation and mechanical atomization, achieving vaporization without thermal heating

Inventive Principle:

Principle #36Phase transitions

2Productivity

If ultrasonic module vibrates at fixed frequency, then atomization is achieved, but control over vapor density is limited

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic frequency adjustment mechanism that allows the ultrasonic transducer to operate at variable frequencies. This enables real-time control over the atomization process and vapor density output, adapting to different user needs and liquid viscosities while maintaining high atomization efficiency

Inventive Principle:

Solution Approach 2:

The patent introduces three-dimensional baffle structures within the delivery channel that create turbulent flow patterns. These vertical and angled baffles add dimensional complexity to the flow path, enhancing vapor acceleration and mixing without significantly increasing the overall device footprint
