Magnetic Susceptor Extraction After Safe Aerosol Article Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Removal of susceptor heating elements from aerosol generating articles is challenging due to their embedded nature within the articles, making recovery and recycling difficult, and existing tools lack safety features to prevent user contact with cutting edges.
Innovation Solution
A cutting tool with a passageway and cutting element, combined with a magnetically attractable susceptor heating element removal tool, allows for safe and efficient extraction of the susceptor heating element by cutting and magnetic attraction during passage through the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the susceptor heating element is integrated into the cooking plate assembly, then efficient heating is achieved, but contamination of the susceptor with food particles and bacteria occurs during cooking
Solution Approach 1:
The heating system is divided into two separate components: a reusable cooking plate assembly and a disposable susceptor heating element. The susceptor is placed inside a cavity of the cooking plate, allowing efficient thermal contact while preventing direct exposure to food particles. After use, the disposable susceptor can be removed and discarded, eliminating contamination issues.
Solution Approach 2:
The susceptor heating element is extracted from the permanent cooking plate structure and implemented as a removable, disposable component. This extraction allows the susceptor to be separated from the cooking plate after use, preventing food particle accumulation and bacterial contamination on the susceptor while maintaining efficient heating during the cooking process.
2Ease of manufacture
If the susceptor heating element is disposable and removable, then cleaning and contamination issues are eliminated, but device complexity increases
Solution Approach 1:
The susceptor heating element is designed to nest within a cavity of the cooking plate assembly. The susceptor fits into a specifically shaped recess that provides secure positioning during cooking while allowing easy removal afterward. This nested structure simplifies the overall design compared to traditional integrated heating elements, as the susceptor simply drops into place and can be easily extracted without complex fastening mechanisms.

AI summary
An assembly to facilitate removal of a susceptor heating element from an aerosol generating article includes a cutting tool comprising (i) a body defining a passageway through which the aerosol generating article may be passed, and (ii) a cutting element extending into the passageway. The cutting element comprises a cutting edge arranged to cut the aerosol generating article as the aerosol generating article passes through the passageway. The assembly may include a heating element removal tool comprising a tip configured to magnetically attract the susceptor heating element. Alternatively, the cutting element may comprise a magnet to attract the susceptor heating element as the aerosol generating article passes the cutting element as the aerosol generating article passes through the passageway.
