Cartridge Lid With Segmented Inner Layer For Sealed Aerosol Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional shisha devices using charcoal for heating tobacco generate harmful combustion by-products, while electrically heated devices lack the traditional tobacco experience, and existing cartridges face issues with maintaining freshness and preventing leakage due to unsealed openings.
Innovation Solution
A cartridge design with a lid featuring a weakened inner layer that forms apertures when the outer layer is removed, providing a sealed solution for housing an aerosol-forming substrate and facilitating airflow without compromising freshness or leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cartridge openings are left unsealed, then airflow through the cartridge is facilitated, but freshness is lost and contamination occurs
Solution Approach 1:
The lid is segmented into an inner layer and an outer layer, where the inner layer remains as a seal during storage but allows airflow during use. This segmentation enables the lid to perform dual functions: maintaining freshness when sealed and facilitating airflow when the outer layer is removed.
Solution Approach 2:
The inner layer is pre-configured with weakened regions that will automatically form apertures when the outer layer is removed. This preliminary preparation ensures that airflow paths are created immediately upon opening, without requiring additional user action to pierce or open the inner layer.
2Reliability
If the cartridge is sealed to maintain freshness, then contamination is prevented, but airflow is blocked
Solution Approach 1:
The lid transitions from a static sealed state to a dynamic open state. The inner layer's weakened regions are designed to deform and form apertures when force is applied to remove the outer layer, enabling the structure to adapt its permeability based on usage conditions.
3Ease of operation
If charcoal is used to heat tobacco, then traditional shisha experience is achieved, but harmful combustion by-products are generated
Solution Approach 1:
The heating method transitions from combustion (chemical reaction with oxygen) to vaporization (phase change). By controlling the temperature parameter to vaporize the aerosol-forming substrate without reaching combustion temperatures, harmful by-products are eliminated while maintaining the sensory experience of traditional shisha.
4Object-generated harmful factors
If electric heaters are used to heat tobacco, then combustion by-products are reduced, but traditional tobacco experience is lost
Solution Approach 1:
The aerosol-forming substrate is formulated as a composite material containing tobacco particles mixed with an aerosol-forming substance. This composite allows the electric heater to vaporize the aerosol-forming substance while tobacco particles are heated and aerosolized, combining the cleanliness of electric heating with the authentic tobacco experience.

AI summary
A cartridge includes a body with a side wall and at least one lid arranged to cover a top or a bottom, or both. The cartridge comprises a cavity inside the body configured for receiving an aerosol‐forming substrate. The lid includes an inner layer facing the cavity and an outer layer facing an outside of the body. The inner layer comprises a weakened region. When the outer layer is removed, the weakened region of the inner layer forms an aperture. The cavity is in fluid communication with an outside of the cartridge body via the formed aperture. The aerosol‐forming substrate may include tobacco. The cartridge may be a shisha cartridge and the aerosol‐forming substrate may be a shisha substrate, such as hookah tobacco.
