Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid control products using spherical bodies for backflow prevention and flow interruption suffer from limitations in installation angles and instability in fluid flow due to easy movement of the spherical body when not in use.
Innovation Solution
A fluid control valve system incorporating a magnetic ball and a ball holder with a magnet piece, where the magnetic ball is attracted to the mounting portion of the ball holder, preventing arbitrary movement and ensuring stable fluid flow unless interrupted by fluid thrust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spherical body is used for fluid control, then the device can achieve backflow prevention and flow interruption, but the spherical body is prone to easy movement within the product leading to instability in fluid flow
Solution Approach 1:
The patent replaces the conventional mechanical spherical body with a magnetic ball that is controlled by magnetic force. The magnetic ball holder uses magnetic attraction to hold the magnetic ball in position, replacing mechanical constraints with magnetic field control. This allows the magnetic ball to be stably positioned when not in use and smoothly moved when fluid thrust is applied, resolving the instability issue of conventional spherical bodies.
Solution Approach 2:
The patent changes the physical state and control mechanism from mechanical contact to magnetic field interaction. By using magnetic force as the controlling parameter instead of mechanical positioning, the system achieves both stable positioning (when magnetic attraction > fluid thrust) and smooth movement (when fluid thrust > magnetic attraction), improving fluid flow stability while maintaining control functionality.
2Adaptability or versatility
If a spherical body is used for fluid control, then the device can interrupt fluid flow, but the device has limitations in installation angles
Solution Approach 1:
The magnetic ball holder design with its cylindrical structure and magnetic field control provides universal adaptability to different installation angles. The magnetic field acts radially on the magnetic ball regardless of the device's orientation, allowing the valve to be installed at various angles while maintaining reliable fluid flow control functionality.
3Stability of the object's composition
If the magnetic ball is held by magnetic attraction, then the magnetic ball remains fixed and stable, but fluid thrust must overcome this attraction to enable flow interruption
Solution Approach 1:
The patent utilizes magnetic force as a controllable parameter that can be balanced against fluid thrust. By adjusting the magnetic field strength (through magnet size, material, or positioning), the system achieves optimal balance between holding stability and movement responsiveness. The magnetic attraction provides stable positioning during normal operation, while fluid thrust can overcome this force when needed for flow interruption or backflow prevention.

Function Achieved in This Case
The magnetic attraction ensures the magnetic ball remains fixed when not performing fluid interruption, enhancing stability and preventing unwanted movement, thus addressing the limitations of conventional spherical body designs.

AI summary
A fluid control valve includes a valve body having first and second air passages. A first valve air passage is defined between the first air passage and the second air passage. An annular blocking portion is located between the second air passage and the first valve air passage. A second valve air passage is defined through the annular blocking portion and communicates with the first valve air passage. A magnetic ball is movably located in the first valve air passage. A ball holder has a mounting portion and a connecting portion which has an air passage and is connected to an inner wall of the first air passage. The magnetic ball is positioned between the annular blocking portion and the mounting portion which has a magnetic piece. When the fluid control is not in use, the magnetic ball is attracted to the mounting end by the magnet piece.
