Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
E-cigarettes often experience phenomena such as 'e-liquid frying' and 'burnt core' due to incomplete vaporization of the vaporization liquid, leading to a compromised taste during inhalation.
Innovation Solution
A vaporization core design with a liquid guide body and heating body arrangement, where the liquid storage portion is defined between the vaporization and liquid absorbing regions, ensuring the vaporization liquid is fully vaporized by controlling the liquid storage amount and vaporization amount within specific ratios, thereby preventing 'e-liquid frying' and 'burnt core'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the liquid storage amount in the vaporization core is increased, then the vaporization liquid supply is sufficient to avoid burnt core, but the unvaporized liquid accumulates causing e-liquid frying
Solution Approach 1:
The liquid guide body is segmented into distinct functional regions: a liquid absorbing region at the first end, a vaporization region at the second end, and a liquid storage portion in between. This segmentation ensures that liquid is absorbed at one end, stored in a controlled quantity in the middle, and vaporized at the other end, preventing both accumulation (e-liquid frying) and insufficiency (burnt core).
Solution Approach 2:
Different regions of the liquid guide body are designed with different properties: the liquid absorbing region has high porosity for liquid uptake, the liquid storage portion has controlled porosity and volume to hold specific liquid amount, and the vaporization region has optimized surface area for efficient vaporization. This local differentiation allows each region to perform its function optimally.
2Productivity
If the heating power is increased to ensure complete vaporization, then the vaporization efficiency improves, but the risk of burnt core increases
Solution Approach 1:
The liquid storage portion pre-stores the exact amount of liquid needed for vaporization before the heating process begins. This preliminary action ensures that sufficient liquid is already in position in the vaporization region when heating starts, eliminating the risk of burnt core while maintaining efficient vaporization.
Solution Approach 2:
The liquid guide body structure itself provides the liquid storage function through its designed porosity and volume in the liquid storage portion. The structure automatically regulates the liquid amount without requiring external control mechanisms, ensuring consistent liquid supply for complete vaporization.
3Volume of moving object
If the liquid guide body volume is reduced to minimize device size, then the compactness improves, but the liquid storage capacity decreases
Solution Approach 1:
The liquid storage portion is nested within the liquid guide body structure, utilizing the internal porous space rather than requiring separate external storage. This nested design allows the liquid storage capacity to be integrated into the overall structure, minimizing the total volume while maintaining adequate liquid storage.
Solution Approach 2:
The porosity and dimensions of the liquid storage portion are precisely controlled to optimize the liquid storage capacity within the available volume. By adjusting these parameters, the design achieves the minimum required liquid storage amount (T1 ≤ Q1 ≤ 3T1) while keeping the overall vaporization core compact.
