Handheld Aerosol Device Piercing Foil Opening Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating devices face issues with leakage of liquid aerosol-forming substrates from cartridges before use and during attachment, due to the need for manual removal of sealing foils.
Innovation Solution
A handheld aerosol-generating device with a cartridge receiving region equipped with an opening element that automatically pierces the sealing foil of the cartridge upon insertion, preventing leakage and eliminating the need for manual foil removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing foil is provided on the cartridge to prevent leakage, then leakage prevention is improved, but the device complexity increases due to the need for manual removal and proper attachment procedures
Solution Approach 1:
The opening element automatically pierces the sealing foil when the cartridge is inserted into the cartridge receiving region, eliminating the need for manual removal of the sealing foil by the user. The system performs the opening action itself during the insertion process.
Solution Approach 2:
The opening element is pre-positioned in the cartridge receiving region to perform the piercing action automatically upon cartridge insertion, before the user needs to access the liquid aerosol-forming substrate. This preliminary automated action simplifies the overall attachment procedure.
2Ease of manufacture
If manual removal of sealing foil is required, then ease of manufacture is improved, but loss of time increases due to user intervention before use
Solution Approach 1:
The device automatically performs the foil piercing function through the opening element during cartridge insertion, eliminating the time-consuming manual removal step. The system serves itself by integrating the opening mechanism into the insertion process.
Solution Approach 2:
The piercing action is performed automatically as part of the insertion sequence, before the user needs to use the device. This preliminary automated action eliminates the time loss associated with manual foil removal at the point of use.
3Device complexity
If manual sealing foil removal is implemented, then device complexity is reduced, but object-generated harmful factors increase due to potential leakage during attachment
Solution Approach 1:
The opening element automatically and precisely pierces the sealing foil during insertion, ensuring controlled opening without leakage. The system performs the opening function itself with precision, eliminating the harmful effect of leakage that occurs with manual removal.
Solution Approach 2:
The sealing foil is pierced automatically upon cartridge insertion, before the attachment process completes. This preliminary automated piercing ensures proper opening is achieved before liquid flow begins, preventing leakage during the attachment process.
