Disposable Mesh Nebulizer Replacement Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mesh nebulizers require troublesome maintenance, including cleaning, disinfecting, and replacing the mesh cap, which is costly and difficult to clean, leading to decreased nebulization efficiency and hygiene issues.
Innovation Solution
A mesh nebulizer design featuring a detachable replacement member with a film mesh portion that opposes the vibration surface, allowing for easy assembly and disposal without the need for cleaning or disinfecting, and manufactured at a lower cost with a separate cap and main body, reducing user burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mesh cap is made as a detachable replacement member separate from the cap, then maintenance becomes easier and cost burden is reduced, but the device structure becomes more complex
Solution Approach 1:
The mesh cap is divided into two separate components: the cap body and the replacement member (mesh portion with bottom plate and side wall). This segmentation allows the replacement member to be easily detached and disposed of after use, while the cap body can be reused. The replacement member includes a protrusion portion that engages with the cap body, ensuring proper positioning during assembly while allowing easy separation for maintenance.
2Reliability
If the mesh cap is cleaned and disinfected frequently, then hygiene is maintained, but user burden and time consumption increase
Solution Approach 1:
The replacement member is designed as a disposable component that is replaced after a single use or after a limited number of uses. This eliminates the need for repeated cleaning and disinfection processes, as users simply remove the used replacement member and attach a new one. The protrusion portion on the replacement member ensures proper positioning in the cap body, maintaining nebulization efficiency without requiring user intervention for cleaning or disinfection.
3Reliability
If the mesh cap is replaced frequently, then performance is maintained, but cost burden increases
Solution Approach 1:
By separating the mesh cap into a reusable cap body and a disposable replacement member, the overall cost is reduced. Users only need to replace the inexpensive replacement member rather than the entire mesh cap assembly. This segmentation allows the expensive cap body to be reused multiple times while the cheap replacement member handles the consumable function, significantly reducing the cost burden on users.
4Reliability
If the mesh cap is made as a precision article, then nebulization efficiency is maintained, but cleaning difficulty increases
Solution Approach 1:
The replacement member is designed as a disposable precision component that maintains high nebulization efficiency through its precisely engineered mesh portion and bottom plate. Instead of attempting to clean this precision component, the design allows users to simply replace it when needed. This approach preserves the precision characteristics necessary for effective nebulization while eliminating the practical difficulties of cleaning precision parts.
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 design simplifies maintenance and reduces costs by eliminating the need for frequent replacement and cleaning of the mesh cap, maintaining nebulization efficiency and hygiene while minimizing user expenses.
Implementation Method 1
a driving voltage is applied to the horn vibrator, whereby the vibration surface is vibrated. Accordingly, the medicinal liquid is nebulized and ejected through the mesh portion.

AI summary
A mesh nebulizer includes a main body including a recess with a shape that is open upward. The main body includes a vibration portion with a vibration surface, and a liquid supply portion that supplies the liquid onto the vibration surface. The mesh nebulizer also includes a cap that openably and closeably covers the upper portion of the main body, and a replacement member that is separate from the main body and the cap and detachably mounted in the recess of the main body in advance when the nebulizer is to be used. The replacement member includes a film mesh portion, a bottom plate portion, and a side wall portion. When the cap is closed with respect to the main body, the protrusion portion of the cap presses the bottom plate portion of the replacement member toward the bottom surface of the recess, thus positioning the replacement member in the vertical axis direction of the main body.
