Valve Core Marble Actuation for Smooth Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push-button valve cores suffer from single functionality, sticking, and unsmooth operation, leading to poor user experience.
Innovation Solution
A valve core design with a housing, valve assembly, switching component, control mechanism, and marble, featuring fan blades with angled contact points and a stainless steel marble to reduce friction, allowing simultaneous or independent operation of multiple water outlets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional single-function valve core is used, then the structure is simple, but it cannot meet changing user needs for multiple water outlet configurations
Solution Approach 1:
The valve core is designed with a switching component that can selectively connect different water outlets (first water outlet, second water outlet, or both simultaneously) to the water inlet, enabling a single device to perform multiple functions and meet varying user needs for different washing scenarios
2Ease of operation
If direct contact between control mechanism and switching component is used, then the structure is simple, but friction causes sticking and unsmooth operation
Solution Approach 1:
A marble is introduced as an intermediary element between the control mechanism and the switching component. The marble transmits the pressing force while its spherical shape and material properties reduce friction, preventing direct contact between the control mechanism and switching component, thereby eliminating sticking issues and ensuring smooth operation
Solution Approach 2:
The contact interface is changed from flat-to-flat contact to spherical-to-flat contact through the marble. This parameter change in contact geometry reduces the contact area and friction coefficient, enabling smoother movement and preventing the switching component from getting stuck

AI summary
A valve core which includes a housing, a valve assembly arranged below the housing, a switching component, a control mechanism, and a marble. The valve assembly is provided with a water inlet, a water crossing port, a first water outlet, and a second water outlet. The switching component is movably arranged at the water inlet or the water crossing port or the second water outlet. An end of the control mechanism passes through a top portion of the housing, and another end thereof is biased against the switching component. Operating the control mechanism, the marble is driven to push the switching component, so that the water inlet is connected to the first water outlet and/or second water outlet to form two water passages. The control mechanism includes a valve stem and a lifting component, and the marble is arranged between the lifting component and the switching component.
