Smoking Article Mouthpiece With Annular Element For Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smoking article filters do not effectively modify aerosol characteristics, such as removing smoke constituents and imparting desired flavors, while also providing a secure and adjustable attachment mechanism to the smoking article rod portion.
Innovation Solution
A smoking article mouthpiece design featuring an elongate cylindrical element with adjacent portions and an annular element, where the annular element has a larger external diameter than the cylindrical element, allowing for secure attachment and containing smoke modifying additives like activated carbon or botanicals, which can be distributed throughout or contained in frangible capsules, and featuring raised areas for enhanced engagement and airflow restriction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a filter is formed from a plug of fibrous cellulose acetate, then the filter provides basic filtration, but the filter does not effectively modify aerosol characteristics such as removing smoke constituents and imparting desired flavors
Solution Approach 1:
The filter combines multiple materials with different functions: fibrous cellulose acetate for filtration, activated carbon for adsorption of smoke constituents, and fragrance materials for flavor imparting. This composite structure allows the filter to simultaneously perform basic filtration, remove harmful constituents, and modify aerosol characteristics effectively
Solution Approach 2:
Different regions of the filter are assigned different materials and functions: the plug portion provides basic filtration, while specific zones contain activated carbon for adsorption and fragrance materials for flavor. This localized functional distribution ensures each material performs its optimal function in the appropriate location
2Object-generated harmful factors
If additives are added to the filter to enhance removal of smoke constituents, then smoke modification is improved, but the filter structure becomes more complex
Solution Approach 1:
Multiple functional additives (activated carbon, fragrance materials, flavorants) are integrated into a single filter structure. The filter combines filtration, adsorption, and flavoring functions in one unified component rather than requiring separate devices, thereby reducing overall system complexity while maintaining enhanced smoke constituent removal
Solution Approach 2:
The filter is designed to perform multiple functions simultaneously: basic filtration of particulates, adsorption of smoke constituents via activated carbon, and imparting desired flavors through fragrance materials. This multi-functional design eliminates the need for separate components for each function
3Reliability
If the mouthpiece is designed as a separate attachable component, then the attachment mechanism can be optimized for secure connection, but the device complexity increases
Solution Approach 1:
The filter assembly is divided into two separate components: a plug portion that fits into the smoking article and a mouthpiece portion that contains the aerosol delivery opening. These segments are designed to attach securely through mechanical interlocking features while maintaining structural integrity
Solution Approach 2:
The mouthpiece is designed to attach to the plug portion through a nested configuration where one component fits within or alongside the other. This nested arrangement provides secure mechanical connection while minimizing the overall footprint and avoiding excessive structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design allows for customizable filtration and aerosol modification, providing enhanced smoke removal and flavor delivery, while ensuring secure attachment to the smoking article rod portion, allowing users to control the filtration level and aerosol characteristics.
Implementation Method 1
Examples include smoke adsorbents such as activated carbon which adsorbs certain smoke constituents thus removing them from the smoke stream passing through the filter.
