Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control valves face challenges in downsizing and weight reduction due to complex connection structures between units, leading to increased size and weight.
Innovation Solution
A control valve design featuring a valve main body and can made of the same metal, with a resin connection member that includes a fastening portion for piping, allowing for integration through welding and insert molding, reducing the number of parts and eliminating the need for dedicated fastening and seal members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated connection parts are used to connect the valve main body and can, then the connection structure is reliable, but the control valve size and weight increase
Solution Approach 1:
The connection member integrates multiple functions into a single component: it serves as both the connection element between valve main body and can, and as the fastening portion for piping parts. This merging eliminates the need for separate dedicated connection parts, reducing overall weight while maintaining connection reliability through the unified structural design.
2Reliability
If multiple dedicated parts are used for connecting units, then the assembly is secure, but the device complexity increases
Solution Approach 1:
The connection member combines the function of connecting the valve main body to the can with the function of fastening piping parts, reducing the number of separate components. This integration simplifies the connection structure while maintaining assembly security through the unified design that ensures proper alignment and secure attachment.
Solution Approach 2:
The connection member is designed as a multi-functional component that performs both connection and fastening operations. This universal design reduces device complexity by eliminating the need for multiple dedicated parts, while still ensuring secure assembly through its dual functionality.
3Strength
If different metal materials are used for valve main body and can, then material properties can be optimized, but corrosion risk increases
Solution Approach 1:
The valve main body and can are both made from stainless steel material, creating homogeneous material composition at the interface. This homogeneity eliminates galvanic corrosion that would occur with dissimilar metals, while still allowing optimization of material properties through the selection of appropriate stainless steel grades and heat treatment processes.
