Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generation devices experience issues with tobacco products shaking within the heating cavity, affecting heat transfer efficiency and stability during use.
Innovation Solution
The device employs a dual-layer support mechanism with staggered, asymmetric protrusions to securely clamp the aerosol-forming article at different heights, utilizing a combination of rigid and flexible elements to stabilize the aerosol-forming article within the cavity, enhancing heat transfer and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a single-layer support mechanism is used, then the device structure is simple, but the aerosol-forming article cannot be stably clamped and shakes during heating
Solution Approach 1:
The support mechanism is divided into two layers: a first support mechanism with first protrusions and a second support mechanism with second protrusions. The first protrusions are closer to the receiving hole while the second protrusions are farther away, creating staged support points that collectively stabilize the aerosol-forming article at multiple positions along its length.
Solution Approach 2:
The support mechanism transitions from a single-plane arrangement to a three-dimensional configuration with protrusions at different axial positions and radial locations. The first and second protrusions are arranged at different heights and positions, creating a multi-dimensional clamping structure that provides comprehensive stability.
2Ease of operation
If the inner diameter of the receiving cavity is made slightly greater than the outer diameter of the tobacco products, then the products can be smoothly received, but the products shake after being received, affecting heat transfer
Solution Approach 1:
The protrusions are positioned to engage with the aerosol-forming article immediately upon insertion, before the heating process begins. The first protrusions are located closer to the receiving hole to provide initial stabilization, while the second protrusions provide additional support points that prevent shaking during the heating cycle.
Solution Approach 2:
Different regions of the support mechanism have different properties: the first protrusions are positioned to provide initial clamping force near the insertion point, while the second protrusions are positioned farther away to provide additional stabilization. This localized arrangement of support elements ensures stability at multiple critical positions along the aerosol-forming article.

Function Achieved in This Case
The dual-layer support mechanism ensures stable reception and efficient heat transfer by minimizing shaking and maintaining the aerosol-forming article's alignment with the heater, thereby improving the generation and inhalation of aerosols.

AI summary
This application provides an aerosol generation device, configured to heat an aerosol-forming article to generate an aerosol for inhalation, the device including a housing, where the housing is internally provided with: a cavity; at least one heater, configured to heat the aerosol-forming article; and a support mechanism, constructed to surround at least a part of the cavity, where an inner surface of the support mechanism is provided with a plurality of first protrusions and a plurality of second protrusions spaced along a circumferential direction to clamp the aerosol-forming article received in the cavity; and the plurality of first protrusions and the plurality of second protrusions are arranged sequentially along an axial direction of the support mechanism. The above aerosol generation device simultaneously clamps the aerosol-forming article at different heights through double-layer protrusions inside, so that the aerosol-forming article can be stably received in the aerosol generation device, and then stably transfer heat with a heater.
