Valve Core Steering Linkage for Vertical-to-Rotary Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressing-controlled valve cores are limited in their driving structure, as the up-and-down movement of the linkage device cannot directly drive the ceramic chip to rotate or laterally displace, restricting flexibility and ability to meet diverse user and manufacturer needs.
Innovation Solution
A steering drive device is introduced, which includes a fixed top frame, lifting drive rod, vertical guide columns, lifting receiving seat, fork-shaped swinging members, and steering linkages, transforming vertical up-and-down movement into transverse rotary motion of the valve rotation actuating seat through a steering linkage mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conventional up-and-down movement linkage device is used, then the structure is simple, but it cannot directly drive the ceramic chip to rotate or laterally displace, limiting functionality
Solution Approach 1:
The patent transforms the conventional up-and-down movement into transverse rotary motion by introducing a steering linkage mechanism. The lifting drive rod's vertical movement is converted through the fork-shaped swinging member and steering linkage into lateral rotation of the valve rotation actuating seat, enabling the ceramic chip to rotate and control water flow directly.
Solution Approach 2:
The patent introduces intermediary components including the fork-shaped swinging member and steering linkage as mediators between the lifting drive rod and the valve rotation actuating seat. These intermediaries transform the vertical lifting motion into transverse rotary motion, enabling direct driving of the ceramic chip without additional matching components.
2Adaptability or versatility
If additional components are added to match existing valve or alter water passage, then water flow control function can be achieved, but the driving structure becomes limited and cannot meet diversified needs
Solution Approach 1:
The steering drive device is designed with universal applicability, where the fork-shaped swinging member and steering linkage can transform vertical movement into rotary motion for different valve configurations. The mechanism accommodates various valve rotation actuating seat positions and ceramic chip arrangements without requiring additional matching components or water passage alterations.
3Ease of operation
If the pressing-controlled lifting actuator directly actuates the valve, then the structure is straightforward, but it cannot achieve transverse rotary motion needed for ceramic chip control
Solution Approach 1:
The patent employs curved motion paths through the fork-shaped swinging member and steering linkage, transforming the linear vertical movement of the lifting drive rod into a curved transverse rotary motion. The eccentric pivot and arc-shaped movement of the swing arms create the necessary rotational trajectory for actuating the valve rotation actuating seat.

AI summary
Disclosed is steering drive device for a pressing-controlled valve core, the steering drive device including a fixed top frame, a lifting drive rod, a vertical guide column, a lifting receiving seat, a fork-shaped swinging member, and a steering linkage. The steering linkage has an end that swings laterally when being moved, and the laterally swinging end is provided with a through hole for the fork-shaped swinging member to drive the swing arm, and cause the horizontal post to axially slide. The vertical cross-section of the through hole is rectangular, and the drive horizontal column has a range of up and down movement space in it, so that, when the drive swing arm generates lateral displacement due to vertical swing, it will pull the steering linkage along a circular path laterally moving, and at the same time drives the valve to rotate the actuating seat and cause it rotate laterally.
