Twisted Susceptor Structure for Efficient Aerosol Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing susceptors used in induction heating methods for aerosol generating articles are difficult to process and have lower heat-generating efficiency due to their uniform volume and structure.
Innovation Solution
Manufacturing the susceptor in a twisted form with wires of varying lengths and diameters, allowing for easy cutting and impregnation with aerosol generating material, which increases the heat-generating area and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple separate molds are used to form different components (nozzle, inlet, outlet) independently, then each component can be precisely formed, but the number of manufacturing steps increases and production time is extended
Solution Approach 1:
The patent combines multiple separate molds (nozzle mold, inlet mold, outlet mold) into a single integrated mold structure that can form all components simultaneously in one injection molding cycle. This merging of molds eliminates sequential manufacturing steps while maintaining the precision of individual component formation, directly resolving the contradiction between manufacturing precision and productivity.
2Productivity
If a single integrated mold is used to form all components simultaneously, then production efficiency increases, but the structural complexity of the mold increases
Solution Approach 1:
The integrated mold is designed with segmented and modular components, where each mold cavity and ejector mechanism is independently structured. This segmentation allows the complex mold to be manufactured, assembled, and maintained more easily, reducing the practical complexity despite the integrated functionality that improves productivity.
3Ease of manufacture
If separate molds are used for different components, then mold design is simpler, but additional steps are required to remove components from molds and transfer them to the housing
Solution Approach 1:
By merging multiple molds into a single integrated mold assembly, the patent eliminates the time-consuming steps of removing components from separate molds and transferring them to the housing. All components are formed and ejected directly in their final positions within the housing, maintaining mold design simplicity while eliminating transfer time.
4Manufacturing precision
If components are formed separately and then assembled, then each component can be optimized independently, but assembly errors and misalignment may occur
Solution Approach 1:
The integrated mold forms all components (nozzle, inlet, outlet, housing) as a unified assembly in a single molding process. This ensures perfect alignment and positioning of all components relative to each other, eliminating assembly errors and misalignment issues while still allowing independent optimization of each component's geometry within the mold design.
