Mouthpiece Composite Wrapper Resolves Wet Strength and Flow Trade-off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mouthpieces used in aerosol provision systems often fail to maintain structural integrity under wet conditions and compressive forces, leading to reduced performance and user experience.
Innovation Solution
A mouthpiece design featuring two or more cylindrical sections wrapped with a high wet strength inner wrapper and a porous outer wrapper, enhancing resistance to moisture and compressive forces while maintaining aerosol flow efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional wrapper is used in the mouthpiece, then the manufacturing cost is low and ease of manufacture is good, but the structural integrity fails under wet conditions and compressive forces
Solution Approach 1:
The mouthpiece employs a composite wrapper structure consisting of an inner wrapper and an outer wrapper. The inner wrapper provides structural integrity and resistance to wet conditions, while the outer wrapper provides additional protection and aesthetic appearance. This composite approach resolves the contradiction by achieving superior strength through material combination rather than single-material complexity.
Solution Approach 2:
The wrapper is divided into distinct functional segments: an inner wrapper section and an outer wrapper section. The inner wrapper is specifically designed to withstand wet conditions and compressive forces, while the outer wrapper provides additional protection. This segmentation allows each layer to be optimized for its specific function, resolving the contradiction between strength requirements and structural complexity.
2Productivity
If a porous wrapper is used, then aerosol flow efficiency is improved, but the resistance to compressive forces and wet conditions deteriorates
Solution Approach 1:
The wrapper is segmented into an inner non-porous wrapper and an outer porous wrapper. The inner non-porous wrapper provides structural integrity and resistance to compressive forces and wet conditions, while the outer porous wrapper allows efficient aerosol flow. This segmentation resolves the contradiction by assigning different functional properties to different segments of the same structure.
3Strength
If the hollow tubular element is made more robust to prevent removal, then structural integrity is improved, but temperature transfer to the outer surface increases
Solution Approach 1:
The inner wrapper is designed with non-uniform thickness, being thicker at the proximal end and thinner at the distal end. This local variation in thickness provides enhanced structural integrity and resistance to removal forces at the proximal end while allowing better heat dissipation at the distal end, thus resolving the contradiction between strength and temperature control.
