Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic atomization apparatuses face issues with high-viscosity atomization liquids failing to replenish the liquid absorber in time, leading to dry burning and peculiar flavors due to poor fluidity.
Innovation Solution
The heater is embedded in the liquid absorber, allowing it to be closely attached and uniformly heat the atomization liquid, with first embedding portions in the annular side wall preheating the liquid to enhance fluidity and prevent dry heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional atomizer is used, then the device structure is simple, but the atomization efficiency is low and clogging occurs
Solution Approach 1:
The atomization core is divided into multiple nozzle holes (first through fourth nozzle holes) with different configurations. Each nozzle hole has specific dimensional parameters (diameters, lengths, positions) that are optimized independently to achieve efficient atomization while preventing clogging, resolving the contradiction between atomization efficiency and device simplicity.
Solution Approach 2:
Different regions of the atomization core have different local structures. The first and second nozzle holes have specific diameter ratios and position relationships that create optimized flow patterns in their local regions, while the third and fourth nozzle holes provide additional atomization pathways. This local optimization achieves high atomization efficiency without requiring complete redesign of the entire device structure.
2Reliability
If the nozzle hole diameter is reduced to prevent clogging, then clogging is reduced, but atomization efficiency decreases
Solution Approach 1:
Instead of using a single large nozzle hole that is prone to clogging, the system segments the atomization function across multiple smaller nozzle holes. The first through fourth nozzle holes have progressively smaller dimensions, with the fourth nozzle hole having the smallest diameter. This segmentation allows the system to maintain reliable atomization without clogging while preserving efficiency through the collective output of multiple nozzles.
Solution Approach 2:
The patent optimizes specific dimensional parameters of the nozzle holes, including diameters (d1, d2, d3, d4), lengths (l1, l2, l3, l4), and positional relationships. By carefully controlling these parameters, the system achieves the smallest possible nozzle diameters that prevent clogging while maintaining sufficient atomization efficiency. For example, the ratio d1/d2 and the positional relationship between nozzle holes are specifically optimized.
3Reliability
If the atomization core structure is complex to prevent clogging, then clogging is prevented, but manufacturing difficulty increases
Solution Approach 1:
The atomization core is segmented into multiple functional zones with distinct nozzle hole configurations. Each segment can be manufactured independently with standard machining processes, and the segments are assembled into the complete atomization core. This segmentation simplifies manufacturing compared to creating a single complex monolithic structure, while still achieving effective clogging prevention through the distributed nozzle configuration.
Solution Approach 2:
The patent specifies precise dimensional parameters for each nozzle hole that can be achieved through conventional manufacturing techniques. The parameters include diameters, lengths, and positional relationships that are within the capabilities of standard machining processes. By optimizing these parameters, the system achieves clogging resistance without requiring complex or expensive manufacturing methods.
