Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flavor inhalation articles face challenges in adjusting fluid filtration effectively using multiple filter materials, as they often require separate regions with different capabilities formed by multiple members.
Innovation Solution
A flavor inhalation article design featuring a filter segment with a filter material comprising both perforated and hole-free regions, formed as a single member, allowing for varying airflow resistance along the axial direction, thereby adjusting filtration without needing multiple separate filter segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple filter materials with different capabilities are joined in a direction of flow to adjust filtration, then filtration performance can be adjusted, but device complexity increases due to requiring multiple separate filter segments
Solution Approach 1:
The patent combines multiple filter materials with different capabilities into a single filter segment by joining them in the radial direction (circumferentially) rather than the flow direction. This merging approach maintains the ability to adjust filtration performance through different material capabilities while reducing device complexity by eliminating the need for multiple separate filter segments arranged in series.
Solution Approach 2:
The patent transitions from arranging filter materials in the flow direction (axial arrangement) to arranging them in the radial direction (circumferential arrangement). This dimensional change allows multiple filter capabilities to coexist within a single segment, enabling filtration adjustment without increasing the number of separate segments along the flow path.
2Adaptability or versatility
If multiple separate filter segments are used to provide different filtration capabilities, then filtration adjustment is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent merges multiple filter materials into a single integrated filter segment, reducing the number of separate manufacturing components. This consolidation simplifies the production process by eliminating the need to assemble multiple separate filter segments while maintaining the ability to provide varied filtration capabilities through radially arranged materials.
3Reliability
If filter materials are arranged in the flow direction to adjust filtration, then filtration performance is optimized, but the structure becomes more complex with multiple members
Solution Approach 1:
The patent repositions the arrangement of filter materials from the flow direction (axial) to the radial direction (circumferential). This dimensional shift allows multiple filter materials to be organized within a single segment, maintaining filtration performance optimization while reducing the number of separate members required in the overall structure.
