Direct-Connect Valve Core for Leak-Safe Hose Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve cores require complex structures and sealing components to ensure airtight connections, leading to increased production costs and potential damage during assembly, which can cause water leakage.
Innovation Solution
A valve core design that allows direct connection to water hoses through dedicated mounting holes and limiting structures, eliminating the need for sealing components between the valve core and the faucet main body, and incorporating axial positioning to maintain stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing components are added to ensure airtight connection between valve core and faucet main body, then sealing performance is improved, but device complexity and production cost increase
Solution Approach 1:
The patent removes the sealing components from the valve core assembly and transfers the sealing function to the faucet main body through integrated sealing structures. The valve core directly connects to water hoses without requiring separate sealing rings or gaskets, thereby simplifying the overall structure while maintaining reliable sealing performance.
2Reliability
If sealing components are added to ensure airtight connection, then sealing performance is improved, but production cost increases
Solution Approach 1:
The patent eliminates the need for separate sealing components by integrating sealing functions into the faucet main body structure. This reduction in part count directly lowers production costs while maintaining effective sealing through the simplified direct-connection design.
3Reliability
If sealing components are used for connection, then airtight connection is achieved, but assembly process becomes complex and sealing components are easily damaged
Solution Approach 1:
The patent removes vulnerable sealing components from the assembly process and replaces them with a robust direct-connection design. The valve core connects directly to water hoses through integrated mounting structures, eliminating the risk of sealing component damage during assembly while ensuring reliable airtight connections.
4Device complexity
If direct connection structure is adopted, then device complexity is reduced, but positioning stability may be compromised
Solution Approach 1:
The patent divides the positioning function into separate limiting structures (limiting groove and limiting protrusion) that are integrated into the direct connection design. These dedicated positioning elements ensure stable alignment between the valve core and water hoses while maintaining the overall simplicity of the direct-connection structure.
