Embedded Solenoid Valve Power Cylinder for Compact Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid pressure cylinders with externally attached solenoid valves increase the overall volume, making it difficult to predict installation space requirements and complicating the installation process.
Innovation Solution
The power cylinder integrates the solenoid valve with the top cover, eliminating the need for separate installation and maintaining the cylinder's volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the solenoid valve is externally attached to the cylinder barrel, then the solenoid valve can be easily installed and maintained, but the overall volume of the fluid pressure cylinder significantly increases
Solution Approach 1:
The solenoid valve base is integrated with the cylinder barrel to form a unified structure. The base of the solenoid valve is directly formed as an extension of the cylinder barrel, eliminating the need for separate attachment and reducing the overall volume while maintaining installation ease.
Solution Approach 2:
The solenoid valve components are nested within the cylindrical structure. The valve body is positioned within the cylinder assembly, and the base is formed as a hollow extension that nests the valve components inside the overall cylindrical footprint, maintaining a compact form factor.
2Adaptability or versatility
If the solenoid valve is externally attached to the cylinder barrel, then the solenoid valve can be independently replaced, but the installation time increases significantly
Solution Approach 1:
The solenoid valve assembly is segmented into replaceable modules. The valve body can be independently removed and replaced by accessing it through the hollow base structure, maintaining replaceability while reducing installation time through simplified access and assembly.
Solution Approach 2:
The base structure is pre-formed as a hollow extension during cylinder manufacturing, with integrated mounting features and fluid passages already in place. This preliminary preparation eliminates the need for additional installation steps and reduces assembly time when replacing the solenoid valve.
3Ease of repair
If the solenoid valve is externally attached to the cylinder barrel, then the solenoid valve can be easily accessed for maintenance, but the positional relationship with other devices becomes complex
Solution Approach 1:
The integrated base structure serves multiple functions: it forms the cylinder outlet, provides mounting for the solenoid valve, and creates a compact unified assembly. This multi-functionality simplifies the overall system architecture and reduces the complexity of positional relationships while maintaining accessibility for maintenance.

AI summary
A power cylinder with embedded solenoid valve includes a cylinder body having a chamber, a piston assembly in the chamber, a top cover and a bottom cover on two ends of the cylinder body, and a solenoid valve disposed on the top cover. The top cover includes an inlet, two outlets, a movement bore, a first passage, and a second passage. The inlet and the two outlets are connected with the movement bore, allowing a fluid to enter the chamber. The bottom cover includes a third passage connected with the first passage and the chamber. A valve stem of the solenoid valve is disposed in the movement bore, reciprocating between a first and a second position for the fluid to push the piston assembly toward or away from the top cover. Thus, the solenoid valve and the power cylinder are integrated.
