Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nebulizer treatments face challenges in selecting the optimal mesh for medicine and patient compatibility, as it is difficult for patients and pharmacists to determine the appropriate mesh type, leading to suboptimal spray particle diameter and amount of spray, which can result in inefficient treatment.
Innovation Solution
A method involving a computer-based system that acquires medicine attributes and patient breathing ability, using a mesh selection table to select a mesh with specific hole diameters, numbers, and shapes to achieve optimal spray particle diameter and amount, considering surface tension and viscosity of the medicine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the hole diameter of the mesh is reduced to decrease spray particle diameter, then the spray particle diameter is reduced, but the amount of spray decreases
Solution Approach 1:
The patent applies parameter changes by systematically varying multiple mesh parameters (hole diameter, number of holes, hole shape) to achieve the desired spray characteristics. Instead of changing only one parameter, the system adjusts multiple parameters in combination to simultaneously reduce particle diameter and maintain spray amount.
Solution Approach 2:
The patent creates a universal mesh selection system that can handle different medicines with varying surface tensions and viscosities. By establishing a comprehensive selection table that considers multiple medicine attributes and patient conditions, the system provides a multi-functional solution applicable to various treatment scenarios.
2Quantity of substance
If the number of holes of the mesh is increased to increase the amount of spray, then the amount of spray is increased, but the spray particle diameter increases
Solution Approach 1:
The patent resolves this contradiction by changing multiple parameters simultaneously. When increasing the number of holes to boost spray amount, the system also adjusts hole diameter and hole shape parameters to compensate for the increase in particle diameter, thereby maintaining optimal spray characteristics.
3Productivity
If the amount of spray is increased to improve treatment efficiency, then treatment efficiency is improved, but the patient cannot inhale all medicine leading to waste and choking
Solution Approach 1:
The patent implements feedback by considering patient breathing ability as an input parameter for mesh selection. The system uses patient-specific information (breathing capacity, age, condition) to determine the appropriate mesh, which then delivers a spray amount matched to the patient's inhalation capability, preventing both waste and choking.
Solution Approach 2:
The patent applies local quality by customizing the mesh selection to each patient's specific breathing ability. Instead of using a uniform spray amount for all patients, the system adjusts the spray characteristics locally according to each patient's inhalation capacity, ensuring optimal delivery without overflow or waste.
4Manufacturing precision
If the spray particle diameter is reduced to reach deeper lung areas, then treatment effect is improved, but the amount of spray required increases
Solution Approach 1:
The patent resolves this contradiction through coordinated parameter changes in the mesh design. By adjusting hole diameter, number of holes, and hole shape together, the system generates finer particles that reach deeper lung areas while compensating for the increased total amount of spray through optimized mesh geometry.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for optimal nebulizer treatment by selecting a mesh that adjusts spray particle diameter and amount to fit the medicine and patient, minimizing main body adjustments and ensuring efficient delivery of medication.
Implementation Method 1
The liquid supplied to the space between the mesh and the oscillation source is sprayed to the outside through the fine holes as a result of oscillation of the oscillation source
Implementation Method 2
the spray particle diameter and the amount of spray of a medicine are affected by the surface tension and the viscosity of the medicine, in addition to the hole diameter, the number of holes, and the hole shape of the mesh
