Embedded Silencer Manifold Base for Solenoid Valve Exhaust Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manifold bases for solenoid valves require additional silencers to be attached for noise attenuation, which complicates the design and increases size and weight, whereas embedding a silencer within the manifold base is not effectively streamlined.
Innovation Solution
The manifold base incorporates an elongated groove for a silencer made of porous noise reduction material that spans across valve mounting regions, with a support groove at the bottom for secure installation, allowing for integrated noise attenuation within the base body.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a silencer is additionally mounted to the opening of the main air discharge channel in a known manifold base, then exhaust noise can be attenuated, but the design becomes complicated and size/weight increase
Solution Approach 1:
The silencer is merged with the manifold base by forming it as an integrated component within the base body. The silencer is formed as a hollow cylindrical structure with porous material filling the interior space, and it is positioned to communicate with the main air discharge channel through a communication hole, thereby integrating noise attenuation functionality into the manifold base structure itself
Solution Approach 2:
The manifold base is designed to serve multiple functions: it provides the main air supply and discharge channels for solenoid valves, mounts multiple solenoid valves on its top surface, and simultaneously incorporates a silencer for noise attenuation. This multi-functional design eliminates the need for separate silencer components

The silencer is nested within the manifold base structure. The hollow cylindrical silencer is positioned inside the base body, utilizing the existing structural space of the manifold base, thereby avoiding additional external space and minimizing weight increase
3Object-affected harmful factors
If a silencer is additionally mounted to the opening of the main air discharge channel in a known manifold base, then exhaust noise can be attenuated, but manufacturing becomes less streamlined
Solution Approach 1:
The silencer is merged with the manifold base by forming it as an integrated component within the base body. The silencer is formed as a hollow cylindrical structure with porous material filling the interior space, and it is positioned to communicate with the main air discharge channel through a communication hole, thereby integrating noise attenuation functionality into the manifold base structure itself
Solution Approach 2:
The silencer is pre-formed as a hollow cylindrical structure with porous material filling before being integrated into the manifold base. This preliminary preparation of the silencer component allows for standardized manufacturing processes and facilitates easier assembly into the final manifold base product
