Solution Overview
Problem
Conventional heaters with ceramic cores and heating wires face issues with e-liquid deposition on the heating wire, leading to dirt formation and inefficient vapor production due to direct contact.
Innovation Solution
A heater design featuring a ceramic core with a concave bottom end and a bended heating wire forming a planar disk, which prevents direct contact between e-liquid and the heating wire, ensuring uniform heating and vapor production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the heating wire is directly exposed in the ceramic core, then the heating efficiency is improved, but the e-liquid deposits on the heating wire forming dirt
Solution Approach 1:
The patent introduces a heating wire cover as an intermediary component that wraps around the heating wire. This cover is made of ceramic or quartz material that allows heat transmission while preventing e-liquid from directly contacting the heating wire surface, thus eliminating dirt deposition while maintaining heating efficiency
Solution Approach 2:
The heating wire cover acts as a flexible protective shell that conforms to the heating wire geometry. This thin-walled ceramic or quartz covering provides protection against liquid contact while allowing thermal energy to pass through effectively
2Device complexity
If the e-liquid contacts the heating wire directly, then the heating process is simple, but the vapor production is inefficient due to dirt formation
Solution Approach 1:
The heating wire cover serves as a mediator between the e-liquid and heating wire, allowing the system to maintain simple operation while improving vapor production efficiency by preventing dirt accumulation that would otherwise hinder heating performance
3Device complexity
If the heating wire is exposed, then the structure is simple, but the heating wire deteriorates quickly due to direct e-liquid contact
Solution Approach 1:
The heating wire cover acts as a protective intermediary that shields the heating wire from direct e-liquid contact, significantly improving durability and reliability while adding minimal structural complexity to the overall device
Solution Approach 2:
The heating wire cover is designed as a replaceable protective component that can be easily disposed of and replaced when worn, providing an economical solution to extend the overall system lifespan without requiring complex protection mechanisms
