Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating products face issues with inconsistent hollow cavity lengths, movement of plugging and filtering parts during transportation and smoking, and low production efficiency due to batch filling methods, along with the operational inconveniences and costs associated with multi-hole firmware sections.
Innovation Solution
The aerosol generating product incorporates a composite plugging part with a groove corrugated tube wall and a convergent sheet rod, eliminating the need for multi-hole firmware sections, ensuring stability and airflow channels, and allowing for consistent production through compounding and rolling processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-hole firmware sections are used to block aerosol source-material granules, then granule blocking function is achieved, but manufacturing costs and operational inconveniences increase
Solution Approach 1:
The patent removes the multi-hole firmware section from the system entirely. Instead of using a separate blocking component with multiple holes, the invention uses the natural friction between the granular aerosol source material and the inner wall of the paper tube to achieve granule retention. This extraction of the complex blocking component simplifies the overall device structure and reduces manufacturing complexity while maintaining the granule blocking function.
2Ease of manufacture
If plugging part and filtering part are fixed only by friction with inner wall, then assembly simplicity is maintained, but part stability deteriorates during transportation and smoking
Solution Approach 1:
The patent applies binder to the outer surfaces of the plugging part and filtering part before assembly, creating a preliminary bonding layer that will adhere to the inner wall of the paper tube during the filling process. This preliminary action ensures that when the components are assembled and filled, they will automatically bond to the tube wall, preventing displacement during transportation and smoking while maintaining relative assembly simplicity.
3Ease of manufacture
If batch filling method is used for individual tubes, then filling process is simple, but production efficiency decreases
Solution Approach 1:
The patent merges multiple individual tube filling operations into a single continuous filling process. By designing the plugging part and filtering part with binder coating that adheres to the paper tube inner wall during filling, the invention enables simultaneous filling of multiple tubes in a continuous stream, rather than processing each tube individually. This merging of operations significantly increases production efficiency while maintaining the simplicity of the filling process through the self-adhering mechanism.
4Reliability
If hollow cavity section is reserved between filtering part and plugging part, then aerosol gathering is enabled, but consistent axial length positioning becomes difficult
Solution Approach 1:
The patent applies binder to the outer surfaces of the plugging part and filtering part in advance, which creates a bonding mechanism that automatically positions these components at fixed locations on the inner wall of the paper tube during filling. This preliminary bonding preparation ensures that the hollow cavity section between the filtering part and plugging part maintains a consistent axial length across all produced items, as the binder-adhered components are reliably positioned during the filling process rather than requiring post-filling adjustment or complex positioning fixtures.

AI summary
The present disclosure discloses an aerosol generating product with a composite plugging part, including an integrated outer sleeve (1), an aerosol generating matrix (6), a plugging part (2), a hollow cavity structure (3) and a filtering part (4) located inside the outer sleeve (1); the plugging part (2) includes a tube wall (21) and a tube cavity (22), the tube wall (21) has a groove corrugated structure, including an outer layer (211), an inner layer (212), and a groove corrugated layer (213) between them; the outer layer (211) limits the outer surface of the plugging part (2), and the inner layer (212) limits the tube cavity (22); a convergent sheet rod (221) is provided inside the tube cavity (22). During smoking, the convergent sheet rod shrinks by heat and blocks part of the central airflow, so that more aerosols contact with aroma-enhancing materials and / or smoking materials on the groove corrugated layer (213), thereby improving the effect of aerosol flavoring and increasing smoke amount.
