Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an aerosol generating article that improves hygiene and user convenience, with a focus on low weight and increased portability, while offering varying smoking experiences through different liquid compositions in each segment.
Innovation Solution
The aerosol generating article consists of multiple segments, including a first segment with a paper sheet impregnated with a first liquid composition and a second segment with a paper sheet impregnated with a second liquid composition, both containing tobacco materials, moisturizers, and flavor materials, with the aerosol generating device incorporating a heater and a cooler, allowing for consistent puffing and enhanced smoking satisfaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a disposable aerosol generating article is used, then hygiene is improved, but device complexity increases
Solution Approach 1:
The aerosol generating article is divided into multiple segments including a first segment with first liquid composition, a second segment with second liquid composition, a cooler segment, and a filter segment. Each segment performs a specific function, allowing the disposable article to maintain hygiene while managing complexity through functional modularization.
Solution Approach 2:
The multiple functional segments are nested within a single disposable aerosol generating article structure. The first segment, second segment, cooler, and filter are arranged in sequence within the same article, integrating multiple functions into one disposable unit that improves hygiene without requiring separate components.
2Adaptability or versatility
If multiple segments with different liquid compositions are used, then smoking impression is improved, but manufacturing precision requirements increase
Solution Approach 1:
Different segments of the aerosol generating article have different liquid compositions tailored to specific functions. The first segment contains a first liquid composition while the second segment contains a second liquid composition, allowing each local region to provide optimized smoking characteristics for its specific role in the aerosol generation process.
3Adaptability or versatility
If liquid composition is varied in each segment, then smoking satisfaction is enhanced, but loss of substance increases
Solution Approach 1:
The liquid composition is segmented into different functional segments rather than using a single uniform composition throughout. This allows each segment to contribute differently to the aerosol generation, improving smoking satisfaction while the overall system is designed to minimize substance loss through efficient aerosolization in each segment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides improved hygiene and user convenience due to disposability, consistent puff numbers, and enhanced smoking satisfaction by varying the liquid compositions, ensuring a uniform smoking experience without the need for an additional mouthpiece.
Implementation Method 1
a heater heated by power supplied from the battery
Implementation Method 2
a cooler arranged at a downstream end of the second segment and including a cooling element
