Solution Overview

Problem

Conventional electronic cigarette atomizers with cylindrical ceramic cores and helical heating wires have a small heating area, resulting in less vapor production and often use fragile glass components.

Innovation Solution

An atomizer design featuring a bowl-shaped ceramic core with a heating wire inside, an e-liquid injection and vapor discharging module comprising an outer and inner tube with a seal ring, silica fixing part, lamp panel, and insulation ring, where the inner tube is made of durable materials like glass or ceramic, and the outer tube is made of inexpensive, high-temperature resistant plastic, enhancing vapor production and user feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a cylindrical ceramic core with helical heating wire is used, then the structure is simple, but the heating area is small resulting in less vapor production

Engineering Contradiction:
Improvevapor productionVSAvoidheating area
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent applies curvature by transitioning from a cylindrical ceramic core to a bowl-shaped ceramic core. The bowl shape provides a concave heating surface that increases the contact area between the heating wire and e-liquid, thereby enhancing vapor production while maintaining structural simplicity

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Reliability

If glass components are used in the atomizer, then the appearance is transparent and aesthetic, but the structure becomes fragile

Engineering Contradiction:
ImprovedurabilityVSAvoidfragility
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent employs composite materials by combining different materials for different components: the outer tube can be made of glass for aesthetic purposes while the inner tube is made of high-temperature resistant plastic for durability, or vice versa. This composite approach allows the atomizer to maintain both transparency and durability simultaneously

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies this principle by using high-temperature resistant plastic for components subject to thermal stress and mechanical wear. Plastic materials are more durable and less fragile than glass in high-temperature environments, sacrificing some aesthetic transparency for significantly improved reliability and durability

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Productivity

If the heating wire has a small heating area, then the structure is compact, but the vapor production is insufficient

Engineering Contradiction:
Improvevapor productionVSAvoidheating structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The bowl-shaped ceramic core with its curved concave surface increases the heating area without significantly increasing device complexity. The curvature allows the heating wire to be arranged in a configuration that maximizes surface contact with e-liquid, enhancing vapor production while maintaining a compact overall structure

Inventive Principle:
Principle #14Spheroidality (Curvature)
