Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic vaporizers face challenges in maintaining consistent vapor production and quality, as existing control systems struggle to independently control the quantity and temperature of the aerosol, leading to potential nicotine overdose and degradation of flavor compounds.
Innovation Solution
A two-stage atomizer system with a primary and secondary heating element, where the primary element controls the quantity of vapor and the secondary element fine-tunes the aerosol temperature, decoupling the amount of vapor from the quality, using a controller to regulate power and temperature to prevent overheating and maintain user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single heating element is used to generate aerosol, then the device structure is simple, but the temperature control precision and particle size consistency deteriorate
Solution Approach 1:
The single heating element is divided into two separate heating elements: a first heating element for generating aerosol and a second heating element for refining particle size. This segmentation allows independent control of temperature and particle size, resolving the contradiction between structural simplicity and precision control.
2Productivity
If high power is delivered to the heating element to increase vapor quantity, then the vapor production increases, but the temperature control precision and flavor compound preservation deteriorate
Solution Approach 1:
The heating function is segmented into two stages: the first heating element generates high-power vapor to ensure sufficient quantity, while the second heating element provides fine temperature control to preserve flavor compounds. This resolves the contradiction between vapor quantity and temperature precision.
Solution Approach 2:
Different heating zones are created with different thermal characteristics. The first heating element operates at higher temperature for vapor generation, while the second heating element operates at controlled temperature for quality maintenance. This local differentiation allows simultaneous achievement of high productivity and temperature control.
3Productivity
If the heating element temperature is increased to improve vaporization efficiency, then the vapor generation improves, but the flavor compound degradation increases
Solution Approach 1:
The vaporization process is divided into two stages: rapid vaporization at the first heating element followed by gentle heating at the second heating element. This segmentation allows efficient vapor generation without excessive temperature exposure that would degrade flavor compounds.
Solution Approach 2:
The first heating element performs preliminary vaporization to generate sufficient vapor quantity, then the second heating element performs fine-tuning to prevent degradation. This preliminary action-sequence ensures both efficiency and quality.
