Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric heating-type aerosol generation devices suffer from poor heating efficiency and increased preheating times due to uneven heating of cigarette mediums, leading to a suboptimal tobacco smoke taste at the beginning of smoking.
Innovation Solution
An aerosol generation device with an adapter that deforms the aerosol-generating article to a desired pressed shape, reducing the distance from the heater to the central portion and minimizing temperature differences, thereby improving heating efficiency and reducing preheating time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a heater is disposed around the cigarette to heat the outer boundary portion of the medium, then the heating structure is simple, but the heating efficiency is poor and preheating time is increased
Solution Approach 1:
The heating structure is divided into multiple heating pieces arranged on opposite inner walls of the heating chamber, allowing simultaneous heating from multiple locations. This segmentation enables the entire medium to be heated more efficiently by distributing the heating function across multiple independent heating elements rather than relying on a single heater.
Solution Approach 2:
The heating pieces are arranged in a three-dimensional configuration within the heating chamber, with multiple heating surfaces facing different directions. This dimensional arrangement allows heat to be applied from multiple spatial directions simultaneously, improving overall heating efficiency compared to a single-point or surface heater.
2Device complexity
If the heater heats the outer boundary portion of the medium, then the heating process is simple, but the central portion is heated slowly and preheating time is increased
Solution Approach 1:
Multiple heating pieces are positioned at different locations around the heating chamber to simultaneously heat different portions of the medium, including the central portion. This segmentation of the heating function eliminates the time delay in heating the central portion by applying heat directly to it through strategically positioned heating elements.
Solution Approach 2:
Different portions of the medium receive heating based on their specific thermal needs. The heating pieces are positioned to provide localized heating to the central portion and outer boundary portions simultaneously, ensuring that each region is heated at the optimal rate rather than following a uniform heating pattern.
3Ease of manufacture
If the medium is heated from the outer boundary portion, then the heating approach is conventional, but temperature distribution is uneven and heating efficiency is decreased
Solution Approach 1:
The heating function is segmented into multiple independent heating pieces that can be positioned at different locations and orientations. This allows each heating piece to target specific regions of the medium, creating a more uniform temperature distribution through coordinated heating from multiple points rather than relying on a single conventional heating approach.
Solution Approach 2:
Each heating piece is designed with specific local characteristics and positioning to address the thermal needs of its corresponding region. This localized heating strategy ensures that temperature distribution is optimized throughout the entire medium, with each region receiving the appropriate heating intensity and duration.
