Inductive Aerosol-Generating Article With Susceptor-Stabilizing Plug
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inductively heatable aerosol-generating articles face issues with consistency due to the susceptibility of the elongate susceptor shifting during handling or transport, leading to potential deformation or dislodgment from the aerosol-forming substrate.
Innovation Solution
Incorporating a plug element upstream of the aerosol-forming substrate to prevent direct contact with the susceptor's distal end, maintaining the susceptor's position and enhancing article consistency, while also providing aesthetic appeal and potential branding information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elongate susceptor extends to the distal end of the aerosol-forming substrate, then the susceptor can be effectively heated by the inductor, but the susceptor position may shift during handling or transport, altering article consistency
Solution Approach 1:
A plug element is introduced as an intermediary component between the susceptor and the external environment. This plug element prevents direct contact with the susceptor during handling and transport, thereby maintaining consistent susceptor positioning without interfering with the inductive heating process. The plug acts as a protective mediator that resolves the contradiction between effective heating and handling stability.
2Power
If the susceptor is exposed at the distal end for inductive heating, then heating efficiency is maintained, but the article aesthetics and branding opportunities are reduced
Solution Approach 1:
The plug element serves as an intermediary that allows the distal end of the susceptor to remain functional for inductive heating while being aesthetically covered. The plug can incorporate branding elements or design features, thus maintaining heating efficiency while improving article appearance and providing branding opportunities.
3Use of energy by moving object
If the susceptor extends beyond the aerosol-forming substrate, then inductive heating can be applied, but the susceptor may become dislodged or deformed during transport
Solution Approach 1:
The plug element acts as a protective intermediary that secures the distal end of the susceptor during transport. It prevents the susceptor from becoming dislodged or deformed while maintaining the inductive heating capability by allowing the susceptor to extend beyond the aerosol-forming substrate for proper electromagnetic field coupling.
