Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic cigarettes face issues with insufficient vapor production due to e-liquid with high viscosity and poor penetrability, often resulting in less or no vapor during initial inhalation, leading to a poor user experience.
Innovation Solution
A heating assembly with a preheating portion made of porous ceramic and positive temperature coefficient (PTC) thermosensitive material, which preheats the e-liquid to improve flowability and ensure sufficient vaporization, connected in parallel with a vaporization portion to efficiently transition from preheating to vaporization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If e-liquid concentration is increased to improve vapor quality and taste, then vaporization effect is improved, but viscosity increases and penetrability deteriorates, resulting in insufficient e-liquid supply to heating body
Solution Approach 1:
The preheating portion is positioned near the liquid outlet to perform preliminary heating of e-liquid before it reaches the vaporization portion. This preliminary action reduces viscosity and improves flowability, enabling high-concentration e-liquid to penetrate effectively to the heating body without compromising vaporization quality
2Reliability
If e-liquid concentration is increased to improve vapor quality and taste, then vaporization effect is improved, but flowability deteriorates, resulting in less vapor during initial inhalation
Solution Approach 1:
The preheating portion performs preliminary heating of e-liquid before it reaches the vaporization portion, improving flowability and enabling sufficient e-liquid supply during initial inhalation while maintaining high concentration for quality vaporization
Solution Approach 2:
The preheating portion changes the temperature parameter of e-liquid, transforming it from a cold, high-viscosity state to a warm, low-viscosity state, thereby improving flowability and penetrability without changing the chemical composition or concentration
3Ease of operation
If preheating function is added to improve e-liquid flowability, then penetrability is improved, but device complexity increases
Solution Approach 1:
The preheating portion and vaporization portion are merged into a single integrated heating assembly structure, where the preheating portion serves as an extension of the vaporization portion, reducing device complexity while maintaining the preheating function
Solution Approach 2:
The heating assembly serves dual functions: the preheating portion improves e-liquid flowability while the vaporization portion performs vaporization, allowing a single component to fulfill multiple functions and avoid adding separate complex subsystems
4Productivity
If parallel circuit connection is used for preheating and vaporization portions, then preheating efficiency is improved, but energy consumption increases
Solution Approach 1:
The parallel circuit connection ensures continuous useful action by allowing simultaneous preheating and vaporization operations, maintaining efficient e-liquid flow and vaporization throughout the device's operation cycle
Solution Approach 2:
The preheating portion performs preliminary heating before e-liquid reaches the vaporization portion, ensuring optimal flow conditions are established in advance, which improves overall system efficiency and reduces energy waste from inefficient vaporization
