Orthogonal Speed Controller Mounting for Compact Fluid Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speed controllers for fluid-pressure cylinders protrude laterally, requiring significant space due to their design, which is a challenge for compact installations in downsized fluid-pressure apparatuses and precision tools.
Innovation Solution
A speed controller design where the main body and mounting portion are oriented orthogonally, with the mounting portion projecting from the side of the main body, reducing lateral protrusion by aligning the central axis with the cylinder port's axis, and incorporating a bulging portion for the mounting body to minimize height and enhance compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the main body and mounting portion are connected in series along the axis, then the speed controller can be mounted on the fluid-pressure cylinder, but the lateral protrusion height becomes large requiring significant installation space
Solution Approach 1:
The patent repositions the mounting portion from a series arrangement along the axis to an orthogonal arrangement, connecting it to the side of the main body instead of the end. This dimensional change in the structural layout reduces the lateral protrusion height while preserving the mounting capability on the fluid-pressure cylinder.
2Length of stationary object
If the mounting portion is connected orthogonally to reduce height, then lateral space is reduced, but the protruding wall portion increases the lateral protrusion height
Solution Approach 1:
The patent extracts and eliminates the protruding wall portion from the structure. By directly connecting the mounting portion to the side of the main body without an intermediate protruding wall, the design achieves compact dimensions while simplifying the overall structure and reducing the number of components.
3Ease of operation
If the speed controller is mounted with the axis aligned to the cylinder port, then mounting is straightforward, but the main body protrudes considerably in the lateral direction
Solution Approach 1:
The patent changes the mounting orientation from axial alignment to orthogonal connection. The mounting portion is connected to the side of the main body, allowing the speed controller to be mounted on the fluid-pressure cylinder while the main body extends in a direction perpendicular to the cylinder axis, thereby reducing lateral space occupation.

AI summary
A valve body of a speed controller includes a main body that extends along a first axis and a mounting portion that projects from a side of the main body along a second axis that intersects the first axis orthogonally. A first port, a needle valve, and a check valve are disposed in the main body. The mounting portion, which is a portion to be mounted on a cylinder portion, includes a second port formed therein. A position at which the mounting portion is disposed on the side of the main body is away from the first axis in a direction of a third axis that orthogonally intersects the first axis and the second axis.
