Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heaters and atomizers in electronic cigarettes are limited by their design, resulting in low output power and limited vapor production, with issues such as e-liquid splashing and core blockage due to precipitate accumulation.
Innovation Solution
A heater design featuring a cylindrical core with three through holes, where three metal wires are coiled into spirals within these holes and extend as pins, connected in parallel, allowing for efficient heat transfer and vapor production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a ceramic core with one or two through holes is used, then the structure is simple and easy to manufacture, but the output power is limited and vapor production is low
Solution Approach 1:
The core is divided into multiple through holes (three through holes) instead of one or two, allowing multiple heating wires to be disposed simultaneously. This segmentation enables parallel heating zones that increase overall heat output and vapor production while maintaining the simplicity of the core structure
Solution Approach 2:
Multiple heating wires are combined in parallel within the same core structure, with their free ends connected together. This merging of multiple heating elements within a single core increases the total power output and heating efficiency without requiring separate core components
2Use of energy by moving object
If heating wires are wound around the ceramic core, then the heating efficiency is improved, but e-liquid splashing occurs and precipitate accumulates blocking the core
Solution Approach 1:
The heating wires are disposed inside through holes of the core rather than wound around the exterior, using the core itself as an intermediary structure that contains and guides the heating wires. This internal disposal prevents direct contact between heating wires and e-liquid, eliminating splashing and precipitate accumulation issues
Solution Approach 2:
The ceramic core with through holes provides a porous-like structure that allows controlled e-liquid flow while containing the heating wires internally. The through holes serve as channels that prevent uncontrolled e-liquid movement and precipitate blockage while maintaining effective heat transfer
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances heater performance with high output power, extended service life, compatibility with various e-liquids, rapid temperature rise, and reduced e-liquid splashing, while minimizing core blockage.
Implementation Method 1
When current is flowing through the metal wire, the metal wire is heated
Implementation Method 2
The heat is transferred to the core to heat the e-liquid to produce vapour
Implementation Method 3
