Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating systems fail to provide high satisfaction to users, including those familiar with heating-type devices and traditional cigarettes, as they do not adequately cater to the diverse preferences and tastes of users.
Innovation Solution
An aerosol generating device that identifies the type of cigarette and heats it according to a specific temperature profile, utilizing a cigarette recognition sensor to differentiate between segments with different aerosol generating substrates, such as nicotine and glycerin, to enhance user satisfaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single temperature profile is used for heating aerosol generating substrates, then the heating process is simple, but user satisfaction is low because it cannot cater to diverse preferences
Solution Approach 1:
The cigarette is divided into multiple segments (first segment with first substrate, second segment with second substrate) that can be independently detected and heated. Each segment has its own identification information that allows the heating device to apply different temperature profiles to each segment, enabling diverse aerosol generation to satisfy different user preferences while maintaining a unified device structure.
Solution Approach 2:
Different segments of the cigarette are assigned different heating characteristics based on their local requirements. The first segment and second segment each receive customized temperature profiles according to their specific substrates (e.g., nicotine-containing material vs. glycerin-containing material), allowing each local region to be optimized for its specific function while contributing to overall user satisfaction.
2Adaptability or versatility
If multiple aerosol generating substrates are used in different segments, then diverse aerosol generation is achieved, but the difficulty of detecting and measuring different substrate types increases
Solution Approach 1:
Identification information is introduced as an intermediary element between the different substrates and the heating control system. This identification information (such as markings, codes, or physical characteristics on the cigarette segments) serves as a mediator that allows the detection device to easily distinguish between different substrate types without requiring complex direct analysis of the substrates themselves, thus simplifying the detection process while enabling diverse aerosol generation.
3Adaptability or versatility
If different temperature profiles are applied to different segments, then high user satisfaction is achieved, but the device complexity increases
Solution Approach 1:
The heating control system is designed to be dynamic and adaptable rather than static. The controller can automatically adjust temperature profiles based on real-time detection results from the detection device. When different identification information is detected in different segments, the system dynamically switches between corresponding temperature profiles, providing flexible temperature control without requiring complex manual intervention or overly complicated hardware designs.
