Solution Overview

Problem

Existing electronic vaporizing devices have complex structures, inconvenient assembly, low production efficiency, and uneven vaporization due to small heating areas and upward vapor flow, which allows unvaporized droplets to escape.

Innovation Solution

A vaporizer design with a vaporization cavity at the inner bottom of the vaporization core, featuring a heating sheet with a large contact area and a configuration that directs vapor flow downward, preventing unvaporized droplets from being inhaled.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If heating coils are used with small contact area, then device structure is simple, but vaporization area is small and heating is uneven

Engineering Contradiction:

Improveheating structureVSAvoidvaporization area

Core Design Contradiction:

Device complexityVSArea of stationary object

Solution Approach 1:

The patent merges the heating function and vaporization function into a single integrated heating plate structure. The heating plate serves both as the heating element and the vaporization surface, eliminating the need for separate heating coils and liquid guiding members. This integration increases the vaporization area while maintaining structural simplicity, directly resolving the contradiction between device complexity and vaporization area.

Inventive Principle:

Principle #5Merging (Combining)

2Speed

If vaporization cavity faces upward with direct communication to vapor passage, then vapor flow is smooth, but unvaporized droplets flow out easily

Engineering Contradiction:

Improvevapor flowVSAvoidunvaporized droplets

Core Design Contradiction:

SpeedVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the traditional upward-facing vaporization cavity design by making the heating plate's vaporization surface face downward toward the liquid reservoir. This inversion allows vapor to form and rise naturally through the heating plate structure while the downward-facing design prevents unvaporized droplets from directly entering the vapor passage. The vapor flow remains smooth through the heated liquid, but harmful droplets are effectively blocked, resolving the contradiction between vapor flow speed and droplet prevention.

Inventive Principle:

Principle #13The other way round (Inversion)

3Adaptability or versatility

If multiple separate components are used for vaporization core, then assembly is flexible, but assembly process is complicated and production efficiency is low

Engineering Contradiction:

Improveassembly flexibilityVSAvoidproduction efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent combines multiple separate components (heating element, vaporization surface, and support structure) into a single integrated heating plate assembly. This merger simplifies the assembly process by reducing the number of parts that need to be manually fitted together, thereby increasing production efficiency. The integrated design maintains adaptability as the heating plate can still be easily installed and replaced as a single unit, resolving the contradiction between assembly flexibility and production efficiency.

Principle #5Merging (Combining)
