Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of electromagnetic valves is complicated and costly, and they experience significant solid friction during operation, affecting their accuracy.
Innovation Solution
The electromagnetic valve design incorporates fluid ducts between the valve sleeve and magnetic pole, with transverse bores and cavities that provide a cost-effective fluidic connection and reduce solid friction, allowing for pressure control, throttle, and switching functions through the interaction of the valve slide with the electromagnet and restoring spring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the valve assembly is enclosed completely by the housing of the electromagnet, then the structural integrity is improved, but the production complexity increases and manufacturing cost rises
Solution Approach 1:
The valve assembly is separated from the electromagnet housing, allowing independent manufacturing and assembly of the two components. The valve body with integrated fluid ducts is manufactured separately and then mounted to the electromagnet, simplifying production while maintaining structural integrity through controlled mounting interfaces.
2Reliability
If traditional valve assembly design is used, then the valve function is achieved, but solid friction between movable components increases and accuracy decreases
Solution Approach 1:
A fluid film is introduced between the movable valve components to replace solid friction with fluid friction. The fluid ducts deliver hydraulic fluid that creates a lubricating film between sliding surfaces, dramatically reducing friction and improving accuracy while maintaining reliable valve operation.
3Adaptability or versatility
If complex fluid connections are implemented, then the valve control functions are improved, but the manufacturing cost increases
Solution Approach 1:
The fluid ducts are integrated directly into the valve body structure, combining the functions of fluid distribution and valve housing into a single component. This eliminates the need for separate fluid connection components and complex assembly procedures, reducing manufacturing cost while providing versatile pressure control, throttle, and switching functions.
