Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating devices face challenges in securely inserting and maintaining aerosol-generating articles due to changes in article dimensions during use, leading to loosening within the cavity.

Incorporation of a resilient sealing element with a funnel-shaped central aperture and flexible properties to aid central alignment and secure insertion of aerosol-generating articles, adapting to varying diameters and preventing loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the cavity diameter is optimized to match the aerosol-generating article diameter for heating efficiency, then heating efficiency is improved, but insertion difficulty increases
Solution Approach 1:
The resilient sealing element acts as a flexible component that deforms during insertion to accommodate misalignment, then returns to its original shape to provide a tight seal. This flexible element allows the cavity to maintain its optimized diameter while compensating for insertion errors through elastic deformation
2Use of energy by moving object
If the cavity diameter corresponds exactly to the aerosol-generating article diameter, then heating efficiency is improved, but alignment precision during insertion deteriorates
Solution Approach 1:
The resilient sealing element changes its physical parameters (shape, volume, stiffness) dynamically during insertion. Initially, it deforms to allow misaligned insertion, then transitions to a constrained state that provides precise alignment and sealing, effectively decoupling the cavity diameter from strict alignment requirements
3Reliability
If the aerosol-generating article is held tightly in the cavity, then loosening is prevented, but insertion difficulty increases
Solution Approach 1:
The resilient sealing element is pre-loaded with elastic energy that acts as a cushioning force during insertion. This pre-compression allows the element to initially yield to insertion force, then progressively engage to provide secure holding, preventing the harshness of immediate tight engagement
