Core Design Contradiction:

SpeedVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the combustion-based heating system with an ultrasonic vibration system. The ultrasonic nebulizer uses high-frequency mechanical vibrations to atomize water and essence directly into fine mist, eliminating the need for combustion while achieving effective aroma diffusion. This substitution resolves the contradiction by maintaining diffusion effectiveness without generating harmful combustion byproducts.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent utilizes phase transition of water from liquid to vapor/mist form through ultrasonic vibration. The ultrasonic nebulizer converts liquid water into fine aerosol droplets that evaporate and diffuse into the air, providing aroma diffusion without combustion. This phase transition approach achieves the desired diffusion effect while avoiding harmful smog generation.

Solution Approach 1:

The patent employs ultrasonic vibration (mechanical vibration at high frequency) to actively atomize and diffuse aroma substances. The ultrasonic nebulizer generates high-frequency vibrations that break water and essence into fine droplets, significantly enhancing diffusion speed and range compared to passive natural volatilization, while maintaining safety by eliminating combustion.

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent transitions from static natural volatilization to dynamic ultrasonic atomization. The system uses active ultrasonic vibration to continuously generate and propel aroma mist into the environment, creating dynamic diffusion that overcomes the limitations of slow, passive natural volatilization while maintaining safety.

Solution Approach 1:

The patent changes the temperature parameter of the generated mist from cold to warm by incorporating a heating element. The heated ultrasonic nebulizer generates warm aromatic mist instead of cold fog, increasing molecular kinetic energy and diffusion activity. This parameter change resolves the contradiction by maintaining convenience while significantly improving diffusion speed and range through enhanced molecular activity.
