Hydraulic Control Valve Connection Surface for Compact Port Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control valves for hydraulic devices, such as pumps, require significant installation space and complex assembly processes due to separate connections for pressure and relief ports, which is problematic in space-constrained applications like vehicle construction.
Innovation Solution
A compact control valve design with a valve housing, piston, and integrated pressure, work, and relief ports that connect via a common connection surface, allowing for simultaneous fluid and mechanical attachment, reducing installation space and assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate connections are provided for pressure ports and relief ports, then reliable fluid connection is achieved, but installation space increases and assembly complexity increases
Solution Approach 1:
The patent combines multiple connection functions (pressure port connection, relief port connection, and mounting) into a single integrated connection surface on the valve body. This allows fluid connections and mechanical mounting to occur simultaneously at one location, reducing the space required for installation while maintaining reliable fluid connections through proper sealing mechanisms.
Solution Approach 2:
The connection surface serves multiple functions simultaneously: it provides mounting surfaces for securing the valve to a support structure, and it provides connection points for both pressure fluid supply and relief fluid discharge. This multi-functionality eliminates the need for separate mounting and fluid connection interfaces, reducing overall installation space.
2Reliability
If separate connections are provided for pressure ports and relief ports, then proper fluid routing is achieved, but assembly work increases
Solution Approach 1:
The patent merges the connection operations for pressure ports and relief ports into a single assembly step at the integrated connection surface. Installers connect both fluid lines and secure the valve to the support structure simultaneously, reducing the number of assembly steps and fastening operations required while maintaining proper fluid routing through dedicated sealed pathways.
3Adaptability or versatility
If multiple separate connections are required, then fluid control functionality is maintained, but installation time increases
Solution Approach 1:
The integrated connection surface enables simultaneous performance of mounting and fluid connection tasks that would otherwise require separate operations. This multi-functional interface allows installers to complete both mechanical attachment and fluid line connections in a single positioning and fastening operation, significantly reducing installation time while preserving full fluid control functionality.
