Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic smoking devices face a challenge in allowing users to choose between high visibility of vapor and high nicotine absorption, as larger particle sizes improve nicotine absorption but reduce vapor visibility, and existing devices do not offer a straightforward way to adjust particle sizes without affecting user behavior.
Innovation Solution
The electronic smoking device features a flow divider with a first and second gas conduit, where the atomizer is arranged in the first conduit, and the second conduit bypasses the first, allowing the flow resistances to be changed while maintaining total flow resistance, thereby adjusting particle sizes by altering the air flow through the atomizer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the particle size of vaporized liquid is increased, then nicotine absorption efficiency is improved, but vapor visibility deteriorates
Solution Approach 1:
The device divides the airflow into two separate parallel pathways: a first gas conduit containing the atomizer for vapor generation, and a second gas conduit that bypasses the atomizer. This segmentation allows independent control of each pathway's flow resistance, enabling adjustment of particle size in the vapor stream without affecting total airflow, thus resolving the trade-off between nicotine absorption and vapor visibility
Solution Approach 2:
The invention changes the flow resistance parameters of the two parallel gas conduits independently. By adjusting the flow resistance in the first conduit (with atomizer) relative to the second conduit (bypass), the device controls the proportion of air mixing with vapor, thereby adjusting particle size and visibility while maintaining constant total flow resistance and consistent user experience
2Illumination intensity
If the flow resistance of the gas conduit is changed to adjust particle size, then visibility or nicotine absorption can be optimized, but the total flow resistance changes affecting user behavior
Solution Approach 1:
The device uses the second gas conduit as a compensatory pathway. When flow resistance in the first conduit is changed to adjust particle size, the flow resistance in the second conduit is adjusted in the opposite direction to compensate, maintaining constant total flow resistance. This counterbalancing approach allows optimization of vapor characteristics without affecting overall airflow and user experience
