Electromagnetic Valve Port Layout for Compact Fluid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of electromagnetic valves in fluid-driven valve devices leads to increased device size due to the placement of inlet, outlet, and discharge ports, which complicates device design and functionality.
Innovation Solution
The design incorporates an electromagnetic valve with an inlet port, an outlet port, and a discharge port, where the inlet and outlet ports communicate in a flowing state and the outlet and discharge ports communicate in a draining state, utilizing a housing, solenoid, stator core, moving core, and valve configuration to manage fluid flow efficiently, allowing the valve to be directly integrated on the valve body without increasing device size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the inlet port is provided on the side of the electromagnetic valve, then the fluid control function is achieved, but the device size increases
Solution Approach 1:
The patent repositions the inlet port from a lateral position on the electromagnetic valve to the top surface of the housing, changing the spatial dimension of port placement. This dimensional change allows the outlet port to be positioned on the bottom surface, enabling a compact vertical arrangement that reduces the overall device footprint while maintaining all necessary fluid control functions
2Device complexity
If the electromagnetic valve is integrated on the valve body, then the device complexity is reduced, but the device size increases
Solution Approach 1:
The patent merges the electromagnetic valve housing with the valve body into a single integrated structure, where the housing serves dual purposes as both the electromagnetic valve enclosure and the valve body itself. This consolidation eliminates the need for separate lateral connections and reduces the overall device volume while maintaining integration benefits
Solution Approach 2:
By positioning ports vertically (inlet on top, outlet on bottom) rather than laterally, the patent enables compact integration of the electromagnetic valve with the valve body in a space-efficient vertical arrangement, reducing the horizontal footprint of the integrated device

AI summary
An electromagnetic valve has an inlet port and an outlet port. The electromagnetic valve is configured to open and close a driving fluid passage communicating the inlet port and the outlet port. The electromagnetic valve includes: a housing; a solenoid that includes a bobbin having a coil wound therearound; a moving core that is provided on an axis of the bobbin and is disposed movably in an axial direction; a stationary core that is provided on the axis of the bobbin and is fixed in the housing; and a valve that is configured to be movable together with the moving core and opens and closes the driving fluid passage. The inlet port is opened on one surface side of the housing in the axial direction of the bobbin while the outlet port is opened on the other surface side of the housing in the axial direction of the bobbin.
