Flavor-Generating Article With Low-Permittivity Microwave Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flavor-generating articles face inefficiencies in heating the flavor source using microwaves due to microwave absorption by filters and components, leading to incomplete flavor generation and potential adherence of heated components to the microwave generating antenna.
Innovation Solution
The flavor-generating article incorporates filters with a relative permittivity of 10 or less, such as mouthpiece and dropping-prevention filters, to minimize microwave absorption, along with features like longitudinally-extending holes and air flow paths to enhance flavor delivery and heating efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter is used in the flavor-generating article, then flavor delivery and component filtration are improved, but microwave absorption increases causing heating efficiency to deteriorate
Solution Approach 1:
The patent changes the dielectric constant parameter of the filter material to 10 or less, which fundamentally alters the microwave absorption characteristics. This parameter change allows the filter to maintain its flavor delivery function while dramatically reducing microwave absorption, thereby resolving the contradiction between filtration reliability and energy loss.
2Reliability
If conventional filters are used, then filtration function is provided, but microwave generating antenna insertion becomes difficult due to adherence
Solution Approach 1:
By changing the dielectric constant parameter of the filter material to 10 or less, the patent reduces the electromagnetic interaction between the filter and the microwave generating antenna. This parameter change prevents adherence during insertion while maintaining the filtration function, thus resolving the contradiction between reliability and ease of operation.
3Reliability
If filters with high dielectric constant are used, then filtration is effective, but microwave transmission to flavor source is blocked
Solution Approach 1:
The patent changes the dielectric constant parameter from conventional high values to 10 or less, which fundamentally alters the microwave transmission characteristics. This parameter change allows microwaves to pass through the filter with minimal attenuation while maintaining filtration effectiveness, thereby resolving the contradiction between filtration reliability and power transmission.
