Modular Extrusion Mold for Variable Aerosol Article Shapes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high production cost of aerosol generating articles is due to the need to replace the entire die for producing articles with different cross-sectional shapes, which is inefficient and costly.
Innovation Solution
A die comprising a first body, a second body, and a third body arranged sequentially, with specific passages and posts that allow for the production of aerosol generating articles with different cross-sectional shapes by replacing only one or two components, rather than the entire die, while controlling porosity and extrusion pressure to ensure molding quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire die is replaced to produce aerosol generating articles with different cross-sectional shapes, then the production of diversified articles is achieved, but the production cost increases
Solution Approach 1:
The die is divided into three independently replaceable bodies: first body, second body, and third body. By replacing only the necessary body(ies) rather than the entire die assembly, the patent reduces manufacturing costs while maintaining the ability to produce articles with different cross-sectional shapes. The modular structure allows selective replacement of components based on production needs.
Solution Approach 2:
The die design allows different bodies to be combined in various configurations to produce multiple article shapes. The first body with cavity can work with different second bodies (with posts) and third bodies (with extrusion passages), creating a universal system that handles diverse production requirements without requiring complete die replacement.
2Adaptability or versatility
If the entire die is replaced to produce aerosol generating articles with different cross-sectional shapes, then the production of diversified articles is achieved, but the production efficiency decreases
Solution Approach 1:
The segmented die structure enables rapid replacement of only the necessary body(ies) rather than the entire die assembly. This reduces downtime during shape changes and improves production efficiency while maintaining versatility for producing different article configurations.
Solution Approach 2:
The die design incorporates dynamic reconfigurability through selective body replacement. The modular architecture allows the production system to adapt quickly to different article shape requirements by swapping only the necessary components, maintaining high productivity across diverse production scenarios.
3Reliability
If the dimensions of cavities and passages are controlled to ensure proper extrusion, then the extrusion stability is improved, but the device complexity increases
Solution Approach 1:
The die is segmented into three bodies with specific functional zones: first body with cavity for material storage, second body with posts for shaping, and third body with extrusion passage for final formation. This segmentation allows each component to be optimized for its specific function while maintaining overall extrusion stability, without requiring complex integrated designs.
Solution Approach 2:
Each body is designed with specific dimensional characteristics optimized for its local function: the cavity dimensions in the first body, the post dimensions and spacing in the second body, and the extrusion passage geometry in the third body. This localized optimization ensures proper extrusion stability while keeping each component relatively simple in design.
