Solution Overview

Problem

Existing ultrasonic electronic cigarette atomizers suffer from tobacco tar accumulation, slow atomization startup, poor sealing, and tobacco tar leakage due to horizontal arrangement of components and downward opening tobacco tar bottle, leading to submersion and poor user experience.

Innovation Solution

The ultrasonic electronic cigarette atomizer features a vertically arranged ultrasonic atomization piece and tobacco tar storage body, with a tobacco tar guide body fixed to the outer wall of the storage bottle to prevent accumulation and leakage, and a side-opening tobacco tar bottle for improved sealing and efficient atomization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the ultrasonic atomization piece and flaky tobacco tar storage body are horizontally arranged below the tobacco tar storage device, then the structure is compact, but tobacco tar accumulates at the storage body and atomization piece due to gravity causing submersion phenomenon and slow atomization startup

Engineering Contradiction:
Improvestructural compactnessVSAvoidatomization startup speed
Core Design Contradiction:
Volume of moving objectVSSpeed

Solution Approach 1:

The patent inverts the conventional horizontal arrangement by adopting a vertical arrangement where the ultrasonic atomization piece and flaky tobacco tar storage body are positioned above the tobacco tar storage device. This inversion utilizes gravity to guide tobacco tar upward to the atomization piece, preventing submersion and enabling rapid atomization startup while maintaining structural compactness.

Inventive Principle:
Principle #13The other way round (Inversion)

2Device complexity

If tobacco tar is output from a downward opening tobacco tar bottle by external guide structure, then the structure is simple, but tobacco tar flows out from gap between guide structure and bottle opening causing poor sealing and leakage

Engineering Contradiction:
Improvestructure simplicityVSAvoidsealing property
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies nesting by integrating the tobacco tar guide structure inside the tobacco tar storage bottle rather than positioning it externally. The guide structure is nested within the bottle cavity, eliminating gaps between the guide and bottle opening, thereby preventing tobacco tar leakage while maintaining structural simplicity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Device complexity

If smoke release surface of tobacco tar storage body is not blocked and communicated with suction nozzle directly, then the structure is simple, but small-granule and large-granule smoke are both inhaled directly causing poor overall taste

Engineering Contradiction:
Improvestructure simplicityVSAvoidinhalation taste quality
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent applies local quality by implementing selective blocking of the smoke release surface. The tobacco tar storage body is blocked except for specific local openings that allow only properly atomized small-granule smoke to pass through to the suction nozzle, while large-granule smoke is redirected back for re-atomization. This local differentiation improves inhalation taste quality while maintaining reasonable structural simplicity.

Inventive Principle:
Principle #3Local quality
