Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the traditional coil-based thermal heating system with an ultrasonic vibration-based atomization system. The ultrasonic module generates high-frequency mechanical vibrations that directly atomize the e-liquid through cavitation and mechanical stress, eliminating the need for thermal heating elements and their associated problems of leakage, overheating, and harmful byproduct generation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs ultrasonic vibration at high frequencies to atomize the e-liquid. The ultrasonic module generates mechanical vibrations that create cavitation bubbles and mechanical stress in the liquid, causing it to break into fine droplets for vaporization without requiring thermal heating, thereby solving the technical contradictions related to safety and reliability.

Inventive Principle:

Solution Approach 1:

The patent integrates the ultrasonic module within the existing device housing, nesting it among other components such as the power source, reservoir, and delivery system. This nested arrangement minimizes the overall device footprint and manages complexity by organizing components in a compact, integrated manner rather than adding separate external systems.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The ultrasonic module serves multiple functions: it atomizes the e-liquid, generates vapor, and can be controlled through frequency adjustment. By making this single component multi-functional, the patent reduces the need for separate mechanisms for each function, thereby managing device complexity while achieving safety and control improvements.

Inventive Principle:
