Mesh Nebulizer Replacement Element for Maintenance Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mesh nebulizers require cumbersome maintenance, including cleaning and replacing a large and expensive mesh cap, which affects spray efficiency and sanitation, and incurs high replacement costs.
Innovation Solution
A mesh nebulizer design featuring a detachable replacement element with a mesh portion that is easily mountable and disposable, reducing maintenance complexity and costs by allowing the mesh cap to be separated from the main body and cap before operation, with a design that includes a sheet with a mesh portion, a bottom plate, and a sidewall portion for precise positioning and efficient atomization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mesh cap is made as a separate detachable replacement element, then maintenance becomes easier and replacement cost is reduced, but the device structure becomes more complex
Solution Approach 1:
The mesh cap is divided into a separate replacement element that can be independently removed and replaced. The replacement element includes the mesh portion mounted on a support structure with positioning features that engage with the main body, allowing users to replace only the mesh cap without disassembling the entire nebulizer device.
Solution Approach 2:
The mesh cap is extracted from the integrated cap structure and formulated as a standalone replacement element. This extracted mesh cap can be easily removed from the main body through a simple detachment mechanism, separating the consumable mesh portion from the reusable main body components.
2Productivity
If the mesh cap is made larger to improve spray coverage, then atomization performance is improved, but replacement cost increases
Solution Approach 1:
The mesh cap is designed with a focused mesh portion that concentrates atomization function in the critical spray area. The mesh portion features optimized hole distribution and size in the central region where spray efficiency is most important, while the support structure provides minimal necessary coverage for structural integrity and positioning.
3Productivity
If the mesh portion is made flat for precise alignment with the vibration surface, then atomization performance is improved, but manufacturing precision requirements increase
Solution Approach 1:
A support structure with a support surface acts as an intermediary between the mesh portion and the vibration surface. The support surface provides a flat, rigid base that ensures proper alignment and spacing, compensating for any minor variations in mesh portion flatness. The sidewall portion further mediates positioning by engaging with corresponding features in the main body to establish precise spatial relationships.
4Productivity
If the mesh cap is designed as a precision component for optimal atomization, then spray efficiency is improved, but cleaning difficulty increases
Solution Approach 1:
The mesh cap is designed as a disposable replacement element with a limited service life. Instead of attempting to clean and maintain the precision mesh cap, the invention allows users to simply replace the entire mesh cap when performance degrades or contamination occurs. This eliminates cleaning complexity while maintaining optimal spray efficiency during the usable period.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies maintenance, reduces replacement costs, and enhances spray efficiency by maintaining the mesh portion's flatness for accurate alignment with the vibration surface, ensuring effective atomization and easy assembly and disassembly.
Implementation Method 1
a vibrator including a vibration surface at a position corresponding to a bottom surface of the recessed portion
Implementation Method 2
a sheet including a mesh portion that faces the vibration surface... This atomizes and sprays the medicinal solution through the mesh portion

AI summary
A mesh nebulizer includes a main body with a recessed portion opening upward. The nebulizer includes a cap that covers an upper portion of the main body and a replacement element separate from the main body and the cap and detachably mountable in the recessed portion of the main body while being separated from the cap prior to operation of the nebulizer. The replacement element includes a sheet including a mesh portion, a bottom plate portion, and a sidewall portion. When the cap is closed with respect to the main body, the cap presses the upper edge of the sidewall portion of the replacement element toward an edge portion around the recessed portion to position the replacement element with respect to a longitudinal axis direction of the main body.
