Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vortex ring generation devices face instability and short outreach due to the generation of straight flow within the vortex ring, leading to premature disappearance and dispersion of scent components when used for aroma transfer.
Innovation Solution
A vortex ring generation device with a casing and extrusion mechanism, where the discharge port diameter, cylinder length, and flow rate are optimized to 0.045 ≤ D ≤ 0.060 m, 0.15 ≤ L ≤ 0.35 m, and 3 ≤ U ≤ 5 m/s, respectively, to stabilize the vortex flow and enhance outreach, using multiple vibration plates to accelerate gas discharge and reduce volume, thereby generating a stable vortex ring with a long outreach.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vortex ring is generated using conventional devices, then the vortex ring can be produced, but the straight flow generated inside the vortex ring causes instability and short outreach
Solution Approach 1:
The patent applies parameter changes by precisely controlling the discharge port diameter (0.045 ≤ D ≤ 0.060 m), cylinder length (0.15 ≤ L ≤ 0.35 m), and discharge flow rate (3 ≤ U ≤ 5 m/s) to optimize vortex ring formation. These parameter adjustments eliminate straight flow generation while maintaining vortex ring stability and extending outreach to 1.5-5 meters.
2Reliability
If the discharge port diameter is increased to enhance vortex ring formation, then the vortex ring can be generated more easily, but the scent component dispersion increases and outreach is reduced
Solution Approach 1:
The patent optimizes the discharge port diameter within a specific range (0.045 ≤ D ≤ 0.060 m) to balance vortex ring formation stability with scent component delivery efficiency. This parameter control prevents excessive dispersion while ensuring reliable vortex ring generation.
3Length of moving object
If the discharge flow rate is increased to extend vortex ring outreach, then the vortex ring can travel farther, but the straight flow increases causing the vortex ring to disappear prematurely
Solution Approach 1:
The patent establishes an optimal discharge flow rate range (3 ≤ U ≤ 5 m/s) that extends vortex ring outreach to 1.5-5 meters while preventing straight flow generation. This parameter optimization ensures both long outreach and sustained vortex ring stability without premature disappearance.
