Aerosol Device Constricting Member for Secure Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating devices face challenges in securely holding aerosol-generating articles without complicating the insertion process, often requiring a compromise between secure gripping and easy insertion.
Innovation Solution
An aerosol-generating device with a constricting member that moves between open and constricting positions to adjust the cavity diameter, allowing secure grip and easy insertion/removal of aerosol-generating articles, featuring a biased constricting member that automatically adjusts to maintain secure grip once the article is inserted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cavity is designed with a fixed small diameter to securely hold the aerosol-generating article, then the gripping security is improved, but the ease of insertion deteriorates
Solution Approach 1:
The cavity diameter is made dynamically adjustable through a moveable constricting member that can transition between an open position (allowing easy insertion) and a constricting position (providing secure gripping). This dynamic adjustment resolves the contradiction by allowing the cavity to adapt its dimensions to the operational phase.
Solution Approach 2:
The physical parameter of cavity diameter is changed from a fixed value to a variable one. The constricting member modifies the cavity's internal diameter based on operational requirements, enabling the system to optimize both insertion ease and gripping security at different stages of operation.
2Ease of operation
If the cavity is designed with a fixed large diameter to facilitate easy insertion, then the ease of insertion is improved, but the gripping security deteriorates
Solution Approach 1:
The cavity transitions from a large fixed diameter (facilitating insertion) to a smaller constricted diameter (providing secure gripping) through the action of the constricting member. This dynamic transformation allows the system to optimize for insertion ease during the insertion phase and for gripping security during the usage phase.
Solution Approach 2:
The cavity diameter parameter is changed from large and fixed to small and adjustable. The constricting member enables this parameter change, allowing the cavity to start large for easy insertion and then constrict to provide secure gripping, thus resolving the contradiction between these two requirements.
3Reliability
If a constricting member is added to enable secure gripping, then the gripping security is improved, but the device complexity increases
Solution Approach 1:
The constricting function is segmented from the main housing structure and implemented as a separate moveable constricting member. This segmentation allows the constricting mechanism to be added modularly without redesigning the entire device, thus improving gripping security while minimizing the increase in overall device complexity.
Solution Approach 2:
The constricting member serves multiple functions: it constricts the cavity for secure gripping, and can potentially assist in holding the aerosol-generating article in place during vaporization. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving reliable gripping.

AI summary
An aerosol-generating device is provided, including: a housing defining a cavity configured to receive an aerosol-generating article, the cavity having an open end through which the aerosol-generating article is receivable into the cavity; and a constricting member connected to the housing, in which the constricting member is moveable between an open position and a constricting position, which selectively constricts at least a portion of the cavity, and in which the constricting member extends around at least part of an outside of the cavity of the housing.
