Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid pressure cylinders with external solenoid valves face challenges in maintaining overall volume during usage, leading to difficulties in determining installation space and positional relationships with other devices, and require additional time for solenoid valve installation.
Innovation Solution
A power cylinder design with an embedded solenoid valve integrated into the top cover, featuring a piston assembly, top and bottom covers, and a solenoid valve with an electronic control unit and valve stem, allowing fluid control within the cylinder chamber without increasing the cylinder's volume and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the solenoid valve is attached to the surface of the cylinder barrel, then the solenoid valve can be installed and function properly, but the overall volume of the fluid pressure cylinder increases significantly
Solution Approach 1:
The solenoid valve base is merged with the top cover of the cylinder barrel to form an integrated structure. The top cover serves dual functions as both a sealing component for the cylinder and as the mounting base for the solenoid valve, eliminating the need for separate attachment and reducing overall volume.
Solution Approach 2:
The top cover is designed with multi-functionality: it seals the cylinder chamber, provides structural support, and serves as the mounting base for the solenoid valve. This universal component approach reduces the number of separate parts and minimizes overall volume.
2Ease of manufacture
If the solenoid valve and fluid pressure cylinder are two independent structures, then each component can be manufactured separately, but additional time is required for installing the solenoid valve onto the cylinder
Solution Approach 1:
The solenoid valve base is integrated into the top cover during manufacturing, creating a single unified component. This merging eliminates the separate installation step, reducing assembly time while maintaining ease of manufacture through standardized production processes.
Solution Approach 2:
The solenoid valve mounting structure is pre-integrated into the top cover during manufacturing, so that when the cylinder is assembled, the solenoid valve is already in its correct position and orientation, eliminating the need for separate installation actions.
3Adaptability or versatility
If external solenoid valves are used with conventional fluid pressure cylinders, then the valve can be installed, but it becomes difficult to determine the needed installation space and positional relationship with other devices in advance
Solution Approach 1:
By merging the solenoid valve base with the top cover, the installation space requirements are clearly defined by the cylinder's external dimensions. The integrated structure makes the positional relationship between the solenoid valve and other devices predictable and planable during the design phase.

AI summary
A power cylinder with embedded solenoid valve includes a cylinder body (10) having a chamber (13), a piston assembly (20) in the chamber (13), a top cover (30) and a bottom cover (40) on two ends of the cylinder body (10), and a solenoid valve (50) disposed on the top cover (30). The top cover (30) includes an inlet (31), two outlets (32), a movement bore (33), a first passage (34), and a second passage (35). The inlet (31) and the two outlets (32) are connected with the movement bore (33), allowing a fluid (F) to enter the chamber (13). The bottom cover (40) includes a third passage (41) connected with the first passage (34) and the chamber (13). A valve stem (52) of the solenoid valve (50) is disposed in the movement bore (33), reciprocating between a first and a second position for the fluid (F) to push the piston assembly (20) toward or away from the top cover (30). Thus, the solenoid valve (50) and the power cylinder are integrated.
