Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing opening/closing valves, particularly butterfly valves and solenoid valves, face challenges in manufacturing costs due to the need for motors and reducers, and struggle with producing valves with larger passage diameters.
Innovation Solution
The development of an opening/closing valve that utilizes a solenoid coil to rotate a valve disk with a magnetic substance, allowing for a larger passage diameter while maintaining low manufacturing costs. The valve disk is rotatable about a rotary shaft and can be configured to open and close the passage effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a butterfly valve is operated in an electric form with a motor and reducer, then the valve can be automated, but manufacturing costs increase
Solution Approach 1:
The patent replaces the mechanical motor-reducer system with a magnetic field-based solenoid coil system. The solenoid coil generates a magnetic field that directly actuates the valve disk containing magnetic particles, eliminating the need for mechanical transmission components like motors and reducers, thereby reducing manufacturing cost while maintaining automation.
Solution Approach 2:
The patent changes the actuation mechanism from mechanical rotation to magnetic field interaction. By utilizing the magnetic properties of particles in the valve disk and the solenoid coil's magnetic field, the system achieves automated valve operation through electromagnetic parameters rather than mechanical parameters, reducing complexity and cost.
2Productivity
If a solenoid valve is designed with a larger passage diameter, then flow capacity increases, but it becomes difficult to produce
Solution Approach 1:
The valve disk is designed with segmented magnetic particles distributed throughout its structure. This segmentation allows the valve disk to be actuated uniformly across its entire surface area, enabling effective control of large-diameter passages without increasing mechanical complexity or manufacturing difficulty.
Solution Approach 2:
The patent uses a magnetic field-based actuation system instead of mechanical systems that would be difficult to scale to large diameters. The solenoid coil generates a magnetic field that penetrates the entire valve disk, providing uniform actuation across large passage diameters without requiring complex mechanical linkages or actuators.
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
This solution enables the creation of an opening/closing valve with a larger passage diameter at a lower manufacturing cost, while maintaining the advantages of prior art designs. The solenoid coil effectively rotates the valve disk to control fluid flow, enhancing the valve's operational efficiency and durability.
Implementation Method 1
A solenoid coil may be mounted on the valve body along the first direction to surround the passage on an outside of the passage. A valve disk including a magnetic substance and may be rotatable within the passage to open and close the passage with the solenoid coil.
