Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating articles face challenges in reducing manufacturing costs while maintaining a cooling function, which is essential for user safety and comfort.
Innovation Solution
The aerosol-generating article is designed with a configuration that includes a medium portion, a first hollow tube, a cooling portion with a cooling element and a second hollow tube, and a filter portion, all wrapped by a single wrapper, where the cooling element and second hollow tube are arranged sequentially downstream, reducing the length of the cooling element to maintain cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a cooling element is added to cool aerosol, then user safety and comfort are improved, but manufacturing cost increases
Solution Approach 1:
The cooling element is designed as a disposable component integrated into the aerosol-generating article, eliminating the need for expensive reusable cooling systems. The cooling element is discarded with the article after use, significantly reducing manufacturing costs while maintaining effective cooling function during the product's lifespan.
Solution Approach 2:
The cooling element utilizes phase change materials that undergo phase transition at specific temperatures to provide cooling effect. By selecting materials with appropriate melting points, the system achieves effective aerosol cooling without requiring complex mechanical cooling systems, thereby reducing manufacturing costs.
2Ease of manufacture
If the cooling element length is reduced to lower cost, then manufacturing cost decreases, but cooling effectiveness may be compromised
Solution Approach 1:
The cooling element features non-uniform structure with varying density or material composition along its length. The region with higher cooling demand has enhanced cooling capacity through increased material density or phase change material concentration, while other regions have reduced material content, optimizing the balance between cooling effectiveness and cost.
Solution Approach 2:
The cooling element is nested within the hollow tube structure, utilizing the existing structural space. This nested arrangement maximizes the cooling element's surface area contact with the aerosol flow path without increasing the overall article length, maintaining cooling effectiveness while minimizing material usage and cost.
