Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing porous ceramics used in electronic atomizers have nonuniform pore structures and poor communication, leading to uneven transmission speeds of atomization liquid, which causes local e-liquid supply issues, carbon deposition, and poor vaping experience.
Innovation Solution
A porous glass with multi-directional communication pores, featuring spherical pores connected to at least six surrounding pores, is developed, along with a fiber skeleton and glass covering for stabilization, ensuring uniform e-liquid transmission and reducing carbon deposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If porous ceramics are used as atomization cores, then good uniformity and long service life are achieved, but the semi-closed pores and fine pores cause absorption of low-viscosity components and rough microscopic surface that is incompatible with thin-film heating films
Solution Approach 1:
The patent transitions from porous ceramics to porous glass as the atomization core material. The porous glass maintains the beneficial pore structure for liquid transmission while providing a smoother microscopic surface that is compatible with thin-film heating films and does not absorb low-viscosity components.
Solution Approach 2:
The invention uses a composite structure combining porous glass with thin-film heating films. The porous glass provides the pore network for liquid supply while the thin-film heating layer provides uniform heating, creating a compatible composite system that resolves the surface incompatibility issue.
2Object-generated harmful factors
If porous glass is used instead of porous ceramics, then smooth and continuous microscopic structure with low proportion of micro-nano pores is achieved, but the nonuniform pore structure and poor pore communication cause significant differences in transmission speeds of atomization liquid
Solution Approach 1:
The patent optimizes key parameters of the porous glass including pore size distribution (5-50 μm), porosity (60-80%), and pore communication structure. By controlling these parameters, the invention achieves uniform transmission speed of atomization liquid while maintaining the smooth microscopic surface characteristic of porous glass.
Solution Approach 2:
The invention creates different pore characteristics in different regions of the porous glass. The pore structure is designed with varying pore sizes and communication pathways to ensure uniform liquid transmission throughout the entire atomization core, addressing the nonuniformity issue while preserving the smooth surface property.
3Device complexity
If one-way communicated open pores are present in porous materials, then pore structure is simplified, but transmission speed of atomization liquid is hindered causing insufficient e-liquid supply and local coking
Solution Approach 1:
The patent transitions from one-way communicated pores to multi-directional communication pores, adding dimensional complexity to the pore network. This multi-directional structure allows atomization liquid to flow through multiple pathways simultaneously, significantly increasing transmission speed and preventing local insufficient supply that leads to coking.
Solution Approach 2:
The pore structure is segmented into multiple communication pathways with different orientations. Instead of a single linear path, the atomization liquid can travel through multiple segmented routes in parallel, increasing overall transmission capacity and speed while distributing flow more evenly throughout the structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The multi-directional communication pores enhance e-liquid transmission speed and uniformity, preventing local e-liquid shortages and carbon deposition, thereby improving the vaping experience.
Implementation Method 1
the pore structure of the porous glass in the prior art is nonuniform and the pore communication is poor. This results in significant differences in the path lengths through which an atomization liquid substrate (e.g., an e-liquid) passes
