Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating apparatuses are limited in their ability to simultaneously implement various flavors according to user preferences due to constraints in design and specifications, making it difficult to offer multiple flavors simultaneously.
Innovation Solution
An aerosol generating apparatus with a replaceable cartridge that includes multiple aerosol generating coating layers, each with different sizes, shapes, and compositions, allowing for independent heating and flavor adjustment, along with a controller to manage the heating of these layers, enabling users to change flavors during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single aerosol generating article is used in the apparatus, then the apparatus structure remains simple, but only one flavor can be provided at a time
Solution Approach 1:
The aerosol generating article is segmented into multiple independent heating zones, each with its own heater and aerosol generating coating layer. This allows different flavors to be generated simultaneously from different segments of the same article, providing flavor variety without requiring multiple separate articles or complex switching mechanisms.
Solution Approach 2:
The single aerosol generating article is designed to perform multiple functions by incorporating multiple heating zones that can operate independently or simultaneously. This multi-functional design allows one article to provide multiple flavors, eliminating the need for multiple separate articles while maintaining structural simplicity.
2Adaptability or versatility
If multiple aerosol generating coating layers are introduced on a single heater, then various flavors can be generated, but the heater becomes overloaded and difficult to control
Solution Approach 1:
The heating function is segmented into multiple independent heaters, each responsible for a specific aerosol generating coating layer. This segmentation allows independent temperature control and power regulation for each heater, making it easy to adjust and control the heating of different flavors without overloading a single heater.
Solution Approach 2:
Each heating zone is designed with local quality characteristics, where each heater is optimized for its specific aerosol generating coating layer. This allows different heating parameters (temperature, power, timing) to be applied to different zones, enabling precise control of each flavor's generation while maintaining overall system simplicity.
3Adaptability or versatility
If a cartridge with multiple heating zones is used, then various flavors can be generated simultaneously, but the cartridge size increases
Solution Approach 1:
Multiple aerosol generating coating layers are merged onto a single cartridge with multiple heating zones, allowing various flavors to be generated simultaneously or sequentially from one compact cartridge. This merging approach provides flavor variety while keeping the cartridge as a single replaceable unit, minimizing the need for multiple separate cartridges.
Solution Approach 2:
The cartridge utilizes a two-dimensional array of heating zones arranged in rows and columns, efficiently packing multiple heating elements within a compact area. This spatial arrangement maximizes the use of available space, providing multiple flavors without significantly increasing the overall cartridge volume.
4Adaptability or versatility
If each heating zone has independent control, then flavor selection is flexible, but the control system becomes complex
Solution Approach 1:
The control system is designed to automatically select and activate the appropriate heating zones based on user input or pre-programmed sequences. This self-service approach provides flexible flavor selection without requiring complex manual control, as the system autonomously manages the heating of different zones to deliver the desired flavor experience.
