Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viscous aerosol-generating substrates in electronic vaporization devices lead to poor fluidity, decreased vaporization amounts, and increased risk of dry burning for the heating assembly.

A vaporizer design incorporating a liquid storage assembly with a preheating member near the liquid inlet hole, which preheats the aerosol-generating substrate to improve fluidity and prevent dry burning by ensuring sufficient liquid supply to the heating assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the aerosol-generating substrate is viscous, then the vaporization amount increases, but the fluidity deteriorates and dry burning risk increases
Solution Approach 1:
The preheating member is positioned near the liquid inlet hole to perform preliminary heating of the aerosol-generating substrate before it reaches the heating assembly. This preliminary action reduces the viscosity of viscous substrates, improving fluidity and preventing dry burning while maintaining adequate vaporization amount.
2Quantity of substance
If the aerosol-generating substrate is viscous, then the vaporization amount increases, but the heating assembly suffers dry burning
Solution Approach 1:
The preheating member performs preliminary heating of the substrate near the liquid inlet hole, ensuring that viscous substrate becomes sufficiently fluid before reaching the heating assembly. This prevents dry burning of the heating assembly while preserving the ability to achieve adequate vaporization amounts.
3Reliability
If the preheating member is located near the liquid inlet hole, then the fluidity improves, but the device complexity increases
Solution Approach 1:
The preheating member is integrated with the existing liquid storage assembly and heating assembly structure. By positioning it near the liquid inlet hole and utilizing the existing thermal field, the design improves substrate fluidity without requiring a completely separate preheating system, thus minimizing the increase in device complexity.
