Woven Fabric Filter with Flavored Sheet Fiber for Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current heating-type stick products face challenges in achieving economic feasibility and effective cooling, as well as flavor expression, due to high production costs and inefficiencies in existing polymer-based filter materials.
Innovation Solution
A woven fabric filter incorporating a flavored sheet fiber made from a cellulose-based polymer, plasticizer, and flavoring material, which provides both airflow cooling and flavor expression effects, is introduced. The flavored sheet fiber has a specific composition and structure that enhances the persistence of smoking taste and tobacco taste by retaining flavoring materials and offering a high tensile strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If polymer materials (PLA, CA, PET) are applied to the entire cross section of the filter as cooling materials, then cooling effect is achieved, but production efficiency is low and product cost is expensive
Solution Approach 1:
The filter cross-section is segmented into multiple functional layers: a first filter layer, a second filter layer containing the flavored sheet, and a third filter layer. This segmentation allows each layer to perform its specific function optimally while enabling more efficient production compared to applying cooling material to the entire cross-section.
Solution Approach 2:
The flavored sheet is positioned specifically in the second filter layer at a location where it can effectively cool the airflow from the medium portion. This local placement provides the necessary cooling effect without requiring expensive polymer materials throughout the entire filter cross-section, thereby improving production efficiency.
2Temperature
If polymer materials are applied to the entire cross section of the filter, then cooling effect is achieved, but product cost is expensive
Solution Approach 1:
The filter is divided into functional layers with the flavored sheet positioned in the second filter layer. This segmentation allows the use of more economical materials in the first and third filter layers while maintaining the cooling function in the second layer, thereby reducing overall product cost.
Solution Approach 2:
The expensive polymer cooling materials are applied locally only where needed (in the second filter layer with the flavored sheet) rather than throughout the entire filter cross-section. This localized application reduces material costs while maintaining effective cooling.
3Ease of manufacture
If no cooling material is placed downstream of the medium portion, then production cost is reduced, but smoker may inhale hot air
Solution Approach 1:
A cooling material (flavored sheet) is placed locally in the second filter layer downstream of the medium portion, specifically at a position where it can intercept and cool the hot airflow before it reaches the smoker. This localized placement provides the necessary cooling function while keeping production costs manageable.
Solution Approach 2:
The flavored sheet acts as an intermediary cooling element between the hot medium portion and the smoker. It intercepts the hot airflow and provides cooling through its phase-change properties, preventing hot air inhalation without requiring a complete downstream cooling system.
4Duration of action of moving object
If flavored sheet with cooling effect and flavor expression is applied, then smoking taste persistence is enhanced, but filter structure complexity increases
Solution Approach 1:
The flavored sheet combines multiple functions into a single component: cooling (through phase-change polymer material), flavor expression (through incorporated flavoring materials), and filtration. This merging of functions enhances smoking taste persistence while adding minimal structural complexity compared to having separate components for each function.
Solution Approach 2:
The flavored sheet serves multiple purposes simultaneously: it acts as a cooling material, a flavor delivery system, and a filtration medium. This multi-functionality allows the filter structure to maintain relative simplicity while achieving enhanced smoking taste persistence through the integrated design.
