Clamp Detection Valve Layout With Shared Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamp devices with multiple detection valves for detecting operation states require a large number of parts, increasing the overall dimension and complexity of the device.
Innovation Solution
The clamp device incorporates a configuration where the valve member of the second detection valve is operated by the manipulation part of the first detection valve, eliminating the need for a separate valve member and reducing the number of parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate detection valves are provided in the housing to detect release state and overstroke state, then the detection function is improved, but the number of parts and overall dimension increase
Solution Approach 1:
The manipulation part of the piston rod serves dual functions: it acts as both the actuator for the first detection valve (overstroke detection) and the valve member for the second detection valve (release state detection). This multi-functionality eliminates the need for separate valve members, reducing part count while maintaining both detection functions.
Solution Approach 2:
The patent combines the functions of the manipulation part and valve member into a single component. The manipulation part that normally actuates the first detection valve is also configured to function as the valve member for the second detection valve, merging two separate components into one integrated element.
2Reliability
If two separate detection valves with independent valve members are arranged in the housing, then the detection capability is improved, but the overall dimension of the clamp device increases
Solution Approach 1:
The manipulation part performs multiple roles including actuating the first detection valve and serving as the valve member for the second detection valve. This multi-functionality allows both detection capabilities to be achieved without proportionally increasing the overall dimension, as one component fulfills multiple functional requirements.
Solution Approach 2:
By merging the manipulation part and valve member into a single integrated component, the patent reduces the total volume occupied by detection valve mechanisms. This integration allows compact arrangement of both detection functions within the housing without increasing overall device dimensions.

AI summary
Provided is a clamp device having a simple configuration comprising a plurality of detection valves for detecting an operation state. A piston rod is provided within a housing so as to be capable of moving vertically. A first detection valve is provided to a first flow path through which flows compressed air for detection, the first flow path being formed within the housing. A valve member of the first detection valve is manipulated by manipulation part provided so as to project radially from the outer peripheral wall of the piston rod. A second detection valve is provided to a second flow path through which flows compressed air for detection, the second flow path being formed within the housing. A valve surface of the second detection valve formed on the manipulation part is capable of engaging with a valve seat formed within the housing.
