Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes with fiber-based liquid storage systems experience uneven vaporization and burning smells due to poor fiber-heating element contact, and struggle with residue removal and flavor changes.
Innovation Solution
The use of ceramic heating elements, either solid or hollow, with integrated heating wires and a design that eliminates the need for fibers, allowing direct e-liquid contact and even vaporization without burning smells, and facilitates easy flavor changes by eliminating residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fiber-based liquid storage systems are used, then liquid solution can be stored and delivered, but uneven vaporization and burning smells occur due to poor fiber-heating element contact
Solution Approach 1:
The patent removes the fiber component from the liquid storage system entirely. Instead of using fiber-based storage, the invention employs a direct liquid reservoir that contacts the heating element, eliminating the source of burning smells and vaporization unevenness caused by fiber-heating element contact issues
Solution Approach 2:
The patent introduces a ceramic coating on the heating element surface as an intermediary layer. This ceramic layer provides a smooth, non-burning surface that facilitates even heat distribution and liquid vaporization without the harmful effects of organic fibers
2Adaptability or versatility
If fiber-based storage is used, then liquid solution can be held, but residue removal and flavor changes become difficult
Solution Approach 1:
By removing fibers from the storage system, the patent eliminates the porous structure that traps residue. The fiberless design allows complete evacuation of previous e-liquid, enabling easy flavor changes without residue contamination
Solution Approach 2:
The patent reverses the application of porous materials by avoiding them in the storage system. Instead of using porous fibers that retain liquid and residue, the invention uses a non-porous or minimally porous ceramic-coated heating surface that allows complete liquid evacuation and easy cleaning
3Reliability
If direct liquid contact with heating element is implemented, then even vaporization without burning smell is achieved, but heating element durability may be reduced
Solution Approach 1:
The patent uses a composite structure combining a metal heating element core with a ceramic coating layer. The metal provides electrical conductivity and heating capability, while the ceramic outer layer provides chemical inertness, heat resistance, and durability, allowing direct liquid contact without compromising element lifespan
Solution Approach 2:
The ceramic coating on the heating element has a controlled porous structure that allows heat transfer while providing a stable, non-burning surface. This porous ceramic layer protects the underlying metal from direct chemical exposure to e-liquid, enhancing durability while maintaining even vaporization
