Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current salt therapy systems produce a significant proportion of salt particles larger than 5 micrometers, which are ineffective for therapeutic purposes, leading to suboptimal treatment results.
Innovation Solution
A salt dust generator with a cylindrical vessel and a net-covered bottom, where salt particles collide with each other and obstacles, and are then separated based on size using air flow and a plate with smaller openings, ensuring that only particles less than 5 micrometers are directed to the therapy device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a filter is used to separate salt particles by size, then particles less than 5 micrometers can be obtained, but the filter clogs quickly and cannot be used effectively
Solution Approach 1:
The invention extracts the filtering function from a traditional filter and replaces it with a net-covered bottom structure. Salt particles are separated by having them fall through a net with specific mesh size (4-5 micrometers) at the bottom of the generation chamber, while larger particles are retained and reused. This extraction of the filtering function eliminates the clogging problem associated with traditional filters.
Solution Approach 2:
The invention changes the separation mechanism from pressure-based filtration to gravity-based particle settling. By controlling the air flow rate and using the natural settling behavior of particles under gravity, the system separates particles by size without using a filter that can clog. The net mesh size is specifically designed to allow therapeutic particles to pass while retaining larger particles.
2Quantity of substance
If salt particles are generated by mechanical milling, then fine particles are produced, but a significant proportion exceeds 5 micrometers and is therapeutically ineffective
Solution Approach 1:
The invention performs preliminary classification of salt particles by using a net-covered bottom with specific mesh size before the particles are used. Salt particles are generated, then immediately separated by having them pass through the net, ensuring that only particles of the correct size (less than 5 micrometers) proceed to the therapy device. This preliminary action ensures size control without requiring precise control of the generation process itself.
Solution Approach 2:
The net-covered bottom acts as an intermediary structure between the salt generation chamber and the therapy device. It mediates the particle size selection by allowing only particles smaller than the mesh size to pass through, while larger particles are retained and can be重新processed. This intermediary structure provides simple yet effective size control.
3Manufacturing precision
If a complex filtration system is used to ensure particle size, then therapeutic effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The invention replaces complex, expensive filtration systems with a simple net-covered bottom structure. The net is a simple, inexpensive component that can be easily manufactured and replaced if needed. This approach prioritizes functional effectiveness over structural complexity, using a simple geometric structure to achieve particle size separation.
Solution Approach 2:
The invention uses a net with specific porosity (mesh size of 4-5 micrometers) as the separation mechanism. This porous structure allows particles of the desired size to pass through while retaining larger particles. The use of porous net material provides an simple and effective alternative to complex filtration systems.

AI summary
A salt dust generator and method for producing salt dust that is used in salt therapy are described where salt dust is generated when salt particles that are moved in an air flow collide with each other and with certain parts of a salt dust generator. By regulating the speed of the air flow, thus changing its capability to carry the salt particles, and using obstacles, for instance nets that are placed into the salt dust generator vessel, it is possible to increase the amount of the collisions of the salt particles and thus make the formation of the salt dust more efficient.
