Cigarette Filter with Dual-Plug Ventilation and Flavor Capsule
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cigarettes do not efficiently deliver flavor in tobacco smoke, as the existing designs focus more on odor reduction and ventilation rather than flavor permeability.
Innovation Solution
A cigarette design featuring a filter structure with a flavor capsule positioned between two filter plugs, where the second filter plug has a lower ventilation resistance than the first, allowing ambient air to increase contact time with the flavor capsule content, enhancing flavor delivery through tobacco smoke by increasing the flavor-to-tar ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional filter designs are used, then odor reduction is achieved, but flavor delivery is inefficient
Solution Approach 1:
The filter is divided into multiple segments with different functions: a first filter plug for odor reduction, a flavor capsule for flavor delivery, and a second filter plug with different ventilation resistance for enhanced flavor delivery. This segmentation allows each component to optimize its specific function without compromising others.
Solution Approach 2:
Different regions of the filter are given different properties: the first filter plug has higher ventilation resistance for odor control, while the second filter plug has lower ventilation resistance to facilitate flavor delivery. The flavor capsule is positioned strategically to receive ambient air and deliver flavor to the tobacco smoke.
2Object-affected harmful factors
If ventilation resistance is increased, then odor control is improved, but flavor permeability decreases
Solution Approach 1:
The filter is segmented into two distinct plugs with different ventilation resistance values. The first plug maintains higher resistance for odor control, while the second plug has lower resistance specifically for flavor delivery, resolving the contradiction between odor control and flavor permeability.
Solution Approach 2:
The flavor capsule acts as an intermediary that receives ambient air through the second filter plug and transfers flavor to the tobacco smoke. This intermediary mechanism allows flavor delivery without requiring the entire filter to have low ventilation resistance, thus maintaining odor control while enabling flavor permeability.
3Quantity of substance
If filter ventilation rate is optimized for flavor delivery, then flavor-to-tar ratio increases, but overall ventilation efficiency may be compromised
Solution Approach 1:
The second filter plug is designed with locally optimized low ventilation resistance specifically in the region where flavor delivery occurs, while maintaining overall filter ventilation efficiency through the combined structure of both plugs and the flavor capsule positioning.
Solution Approach 2:
The ventilation resistance parameter is changed locally in the second filter plug to optimize flavor delivery, creating a gradient from high resistance in the first plug to low resistance in the second plug. This parameter variation allows simultaneous optimization of odor control and flavor delivery.
