Susceptor Segment Integration for Inductive Tobacco Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tobacco products designed for resistive heating devices are not suitable for inductive heating devices, as they do not effectively utilize the alternating electromagnetic field to induce heat for aerosol formation.
Innovation Solution
An apparatus and method that integrates susceptor segments, such as stainless steel strips, directly into tobacco products, allowing them to be used in inductive heating devices by aligning and moving receiving portions to position the susceptor segments within the tobacco products, ensuring thermal proximity and efficient heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tobacco products are designed for resistive heating devices, then they can be manufactured using existing manufacturing processes, but they are not suitable for use in inductive heating devices
Solution Approach 1:
The susceptor segment is inserted inside the tobacco product, creating a nested structure where one component (susceptor) is placed within another (tobacco product). This allows the tobacco product to maintain its original form and manufacturing process while incorporating the additional inductive heating functionality through the embedded susceptor segment.
Solution Approach 2:
The heating functionality is divided into separate components: the tobacco product remains as one segment while the susceptor is provided as a separate segment that can be independently manufactured and then combined with the tobacco product. This segmentation allows each component to be optimized for its specific function while maintaining manufacturing simplicity.
2Reliability
If susceptor segments are inserted into tobacco products, then inductive heating functionality is achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The susceptor segment is prepared in advance as a pre-formed component with the correct shape and dimensions before being inserted into the tobacco product. This preliminary preparation allows for standardized manufacturing of both components separately, simplifying the overall production process while ensuring reliable inductive heating performance when assembled.

AI summary
The method for manufacturing inductively heatable tobacco products comprises the steps of providing a tobacco product, providing a susceptor segment and positioning the susceptor segment in the tobacco product by moving the susceptor segment and the tobacco product relative to each other. Thereby the susceptor segment is pushed into the tobacco product.
