Aerosol Accessory Heating Element Segmentation for Profile Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating devices lack versatility in user experience and adaptability to different usage scenarios, as they often provide limited options for heating the aerosol-forming substrate, restricting the generation of inhalable aerosols.
Innovation Solution
An accessory with a heating element, either induction or resistive, is designed to provide a secondary heating option for aerosol-generating articles, allowing for different heating profiles by heating distinct portions of the aerosol-forming substrate, and is powered by the aerosol-generating device, enabling multiple accessories with unique characteristics for varied aerosol generation regimes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single heating element is used in the aerosol-generating device, then the device structure remains simple, but the adaptability to different usage scenarios and heating profiles is limited
Solution Approach 1:
The heating system is segmented into multiple independent heating elements (first heating element in the device, second heating element in the accessory) that can operate independently or together. This allows different heating profiles and usage scenarios without requiring a completely different device structure.
Solution Approach 2:
The accessory with the second heating element serves multiple functions: it provides additional heating capability, enables different heating profiles when combined with the first heating element, and can be attached or detached as needed. This multi-functionality improves adaptability without permanently increasing device complexity.
2Adaptability or versatility
If multiple heating elements are added to provide different heating profiles, then the adaptability and user experience are improved, but the device complexity increases
Solution Approach 1:
The heating system is divided into separate heating elements located in different components (device and accessory). Each heating element can be controlled independently, enabling multiple heating profiles through different combinations and sequences of heating, without requiring a complex integrated heating system.
Solution Approach 2:
The system dynamically adjusts heating profiles by controlling the timing and intensity of different heating elements. The controller can activate the first heating element alone, the second heating element alone, or both simultaneously or sequentially, providing dynamic adaptability to different usage scenarios.
3Adaptability or versatility
If the accessory includes a heating element powered by the aerosol-generating device, then the accessory can provide additional heating functionality, but the power consumption and energy management complexity increase
Solution Approach 1:
The accessory's heating element utilizes the existing power supply of the aerosol-generating device, allowing the single power source to serve multiple functions (heating in both device and accessory). This reduces the need for separate power sources while providing expanded heating functionality.
Solution Approach 2:
The power consumption is dynamically managed by the controller, which can selectively activate heating elements based on usage requirements. The system can optimize energy distribution between the first and second heating elements to provide desired heating profiles while managing overall power consumption.
