Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generation devices with cylindrical heaters face challenges in heat transfer efficiency to cigarettes, as the heat transfer is reduced compared to internal insertion-type heaters.
Innovation Solution
The aerosol generation device features a heater composed of multiple segments cut from a cylindrical structure, allowing for easy printing of electrically conductive tracks on the inner surface, and an elastic member that ensures close contact between the conductive tracks and the cigarette, enhancing heat transfer efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a cylindrical heater is used to heat the cigarette from the outside, then foreign substance discharge is prevented, but heat transfer efficiency is reduced
Solution Approach 1:
The cylindrical heater is divided into multiple segments that can be separately formed and assembled. Each segment has its inner surface processed to form conductive tracks, allowing direct thermal contact with the cigarette while maintaining the external cylindrical structure that prevents foreign substance discharge.
Solution Approach 2:
The inner surface of each heater segment is specifically processed to form electrically conductive tracks in direct contact with the cigarette, creating localized high-efficiency heat transfer zones. The outer cylindrical surface maintains its smooth structure for preventing foreign substance discharge.
2Ease of manufacture
If the heater is divided into multiple segments, then conductive tracks can be easily printed on the inner surface, but the structure becomes more complex
Solution Approach 1:
The heater is segmented into multiple identical or similar units that can be manufactured separately with conductive tracks printed on their inner surfaces. This segmentation simplifies the printing process compared to a single large cylindrical heater, as each segment can be processed independently using standard printing techniques.
Solution Approach 2:
Multiple heater segments are coupled together to form the complete cylindrical heater structure. The segments are joined in a sequence to create the full-length heater, combining the simplicity of individual segment manufacturing with the functionality of a complete cylindrical heater.
