Collapsible Cartridge Holder for Reusable Aerosol Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional smoking articles suffer from issues such as scorching of wrapping material, production of undesirable gases like carbon monoxide and carbon dioxide, and poor aerosolization, while also being prone to poor performance and requiring non-reusable components.
Innovation Solution
Aerosol delivery devices with collapsible or deflectable holders that accommodate removable and replaceable cartridges, featuring a receiving chamber and internal passageway for aerosol delivery, with mechanisms for easy ejection and retention of cartridges using elastomeric protuberances, magnets, or other retaining features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional smoking articles use combustible carbon-based ignition sources, then heat is generated for aerosol production, but scorching of wrapping material and production of undesirable gases occur
Solution Approach 1:
The device divides the heating system into separate functional components: a removable cartridge containing the aerosol-forming material and a separate holder containing the heating element. This segmentation allows the heating process to occur in isolation from the wrapping material, preventing scorching while maintaining effective heat generation for aerosol production.
Solution Approach 2:
The patent extracts the harmful combustion process from the overall smoking article by using an electrical heating element instead of combustible carbon-based ignition sources. This extraction eliminates the production of undesirable gases like carbon monoxide and carbon dioxide while maintaining the necessary heat generation for aerosol formation.
2Device complexity
If traditional smoking articles use fixed components, then structural simplicity is achieved, but reusability and replaceability are limited
Solution Approach 1:
The smoking article is divided into a reusable holder and a removable cartridge. The holder contains the electrical heating element and power source, while the cartridge contains the aerosol-forming material. This segmentation enables the cartridge to be replaced after consumption while the holder remains reusable, achieving both simplicity and adaptability.
Solution Approach 2:
The device incorporates a dynamic ejection mechanism that allows the cartridge to be easily removed and replaced. The holder can transition between a loaded state and an empty state, with the ejection mechanism providing the necessary motion to expel the used cartridge and accommodate a new one, enhancing user convenience and reusability.
3Reliability
If aerosol delivery devices use complex retention mechanisms, then cartridge retention is improved, but device complexity increases
Solution Approach 1:
The holder incorporates an automatic ejection mechanism that uses the heating element's thermal expansion or electrical actuation to automatically expel the used cartridge without requiring manual intervention. This self-service approach ensures reliable cartridge retention during use while simplifying the ejection process, avoiding complex manual retention mechanisms.

AI summary
The present disclosure is directed to a holder for use with a removable substrate cartridge. In one implementation, the holder comprises a main body that includes a collapsible section configured to collapse in an axial direction into an ejecting position when an ejecting force is applied to the main body. The collapsible portion is further configured to return to the use position when no ejecting force is applied to the main body. In another implementation, the holder comprises a main body that includes at least one deflectable portion configured to rotate relative to the remaining main body into an ejecting position when an ejecting force is applied to the main body. The at least one deflectable portion is further configured to return to the use position when no ejecting force is applied to the main body.
