Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aerosol generating devices face challenges in efficiently managing airflow and aerosol generation, leading to issues such as aerosol deposition on device components and suboptimal user experience.
Innovation Solution
The proposed aerosol generating system features a consumable unit with multiple airflow paths, each associated with a source of aerosol generating medium, and a housing with an air inlet and outlet. This configuration allows for selective alignment of airflow paths with the inlet and outlet, enabling controlled aerosol generation and reduced aerosol deposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single airflow path is used in the consumable unit, then the device structure is simple, but aerosol deposition on device components occurs and user experience is suboptimal
Solution Approach 1:
The consumable unit is divided into multiple separate airflow paths (first airflow path, second airflow path, etc.), each with its own aerosol generating medium source. This segmentation prevents aerosol from a single path from depositing on components used by other paths, thereby reducing aerosol deposition while maintaining manageable device structure through modular design.
2Object-affected harmful factors
If multiple airflow paths are implemented, then aerosol deposition is reduced, but device complexity increases
Solution Approach 1:
Multiple airflow paths are merged into a single consumable unit that can be selectively aligned with the housing inlet and outlet. The housing provides a common structure that accommodates multiple airflow paths, allowing them to share infrastructure while maintaining separate aerosol generation zones, thus reducing aerosol deposition without excessive complexity increase.
Solution Approach 2:
The consumable unit is designed to be selectively positionable within the housing, allowing dynamic selection of which airflow path is active. This dynamic configuration enables the system to switch between different airflow paths based on usage requirements, providing flexibility that justifies the increased structural complexity.
3Device complexity
If airflow paths are fixed, then device structure is simple, but aerosol delivery consistency is suboptimal
Solution Approach 1:
The consumable unit can be selectively positioned to bring different airflow paths into alignment with the housing inlet and outlet. This dynamic positioning capability allows the system to maintain consistent aerosol delivery by selecting the appropriate airflow path based on consumable unit wear or user preference, thereby improving reliability while requiring a more complex configurable structure.
4Reliability
If selective alignment of airflow paths is enabled, then aerosol delivery is enhanced, but ease of operation decreases
Solution Approach 1:
The selective alignment mechanism is designed to be automatically actuated or easily activated by the user through simple actions such as inserting the consumable unit or pressing a button. The system self-manages the complex task of aligning the correct airflow path with the housing, requiring minimal user effort and maintaining ease of operation while achieving consistent aerosol delivery.
