Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic atomizing devices, such as e-cigarettes, face issues with uneven heating temperatures, poor atomization effects, and dry burning due to thermal conductivity differences between metal heating modules and ceramic bases, leading to potential burnt smells and inadequate liquid supply for high viscosity atomizing liquids.
Innovation Solution
The proposed solution involves an atomization core with a liquid absorbing element and a heating module where the heating element is embedded within the liquid absorbing element, allowing for snug attachment and efficient heat transfer. The heating module is designed with multiple heating portions and sub-portions arranged in a three-dimensional structure, enhancing heat distribution and absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a metal heating module is embedded on the surface of the ceramic base and sintered together, then the heating module can be integrated with the ceramic base, but due to the difference in thermal conductivities, the heating module may separate from the ceramic after heating, causing uneven heating temperature and poor atomization effect
Solution Approach 1:
The heating module is embedded within the liquid absorbing element rather than being surface-mounted on the ceramic base. This nested configuration allows the heating module to be surrounded by the liquid absorbing material, ensuring thermal contact while preventing separation due to thermal expansion differences. The heating module becomes integrated into the liquid absorbing element's structure, resolving the contradiction between integration stability and heating uniformity.
Solution Approach 2:
The liquid absorbing element serves as an intermediary medium between the heating module and the atomizing liquid. It conducts heat from the heating module uniformly to the atomizing liquid, preventing direct thermal contact between the metal heating module and ceramic base that would cause separation. This intermediary layer resolves the thermal conductivity mismatch issue.
2Device complexity
If the heating module is arranged on the ceramic base surface, then the structure is simple, but the atomizing liquid with high viscosity has decreased liquid guide rate, resulting in insufficient liquid on the ceramic surface and dry burning
Solution Approach 1:
The heating module is nested within the liquid absorbing element, allowing the atomizing liquid to be absorbed and guided through the liquid absorbing material surrounding the heating module. This ensures that high viscosity liquids are delivered directly to the heating area through capillary action and material permeability, preventing dry burning while maintaining structural simplicity.
Solution Approach 2:
The liquid absorbing element utilizes porous material properties to guide the atomizing liquid from the liquid storage space through the heating module area. The porous structure provides capillary channels that effectively transport high viscosity liquids, ensuring sufficient liquid supply to the heating region without increasing structural complexity.
3Use of energy by moving object
If the heating module is embedded in the liquid absorbing element, then heat transfer efficiency is improved, but the device structure becomes more complex
Solution Approach 1:
The heating module is nested within the liquid absorbing element, creating a compact integrated structure. This nesting approach improves heat transfer efficiency by ensuring direct thermal contact between the heating module and the liquid absorbing material, while the overall structure remains unified and does not significantly increase device complexity.
Solution Approach 2:
The heating module and liquid absorbing element are merged into a single integrated component. The heating module is embedded within the liquid absorbing element, combining the heating function and liquid absorption function into one unified structure, which improves heat transfer while avoiding the need for separate mounting mechanisms.
