Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid spray apparatuses with vibratory sources and mesh members face instability in liquid spraying, leading to inconsistent atomization and potential leakage.
Innovation Solution
A liquid spray apparatus design featuring a recess on the surface of the vibratory source's leading end, where the liquid is supplied and atomized through micropores, with a mesh member attached in an inclined manner to ensure stable spraying by optimizing the geometry and positioning of the recess and mesh member for efficient liquid delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid is supplied to the contact part between the vibratory source and mesh member, then liquid atomization is achieved, but liquid leakage occurs when the apparatus is inclined
Solution Approach 1:
The liquid supply path is segmented into two distinct parts: a first liquid supply path that does not reach the contact part and a second liquid supply path that supplies liquid to the contact part. This segmentation allows the system to maintain reliable liquid atomization while preventing leakage when inclined by controlling which path is active.
Solution Approach 2:
The liquid supply system is made dynamic by providing both a first liquid supply path and a second liquid supply path, allowing the system to adaptively control liquid flow based on operational conditions. The ability to switch between or combine these paths enables the system to maintain stable atomization while preventing inclination-induced leakage.
2Reliability
If the recess depth is increased to improve liquid collection, then liquid supply stability improves, but the risk of mesh member damage increases
Solution Approach 1:
The recess depth parameter is optimized to a specific range (0.03mm to 1.0mm) that balances liquid collection effectiveness with mesh member protection. This parameter optimization allows the recess to provide stable liquid supply while preventing excessive liquid accumulation that could damage the mesh member.
3Reliability
If the recess width is increased to improve liquid supply, then atomization stability improves, but the structural integrity of the vibratory source decreases
Solution Approach 1:
The recess width parameter is controlled to be 5% to 50% of the leading end diameter, optimizing the balance between liquid supply capability and structural integrity. This parameter range ensures sufficient liquid collection area while maintaining the strength necessary for effective vibration.
4Reliability
If the mesh member is attached in an inclined manner to prevent leakage, then liquid supply stability improves, but manufacturing complexity increases
Solution Approach 1:
The mesh member attachment is designed with asymmetric inclination at a predetermined angle, creating an optimized configuration that prevents liquid leakage while maintaining manufacturing feasibility. The asymmetric design allows gravity to work in favor of liquid control rather than against it.

Function Achieved in This Case
The apparatus achieves stable and consistent liquid atomization, preventing leakage and ensuring reliable operation by maintaining a controlled liquid supply to the mesh member, even when inclined, and reducing the risk of mesh member damage.
Implementation Method 1
