Switching Valve Slider Mechanism for One-Touch Outlet Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water dispensing devices lack efficient mechanisms for switching between multiple water discharge modes with a single operation, requiring complex and cumbersome processes to select different outlets.
Innovation Solution
A switching valve design featuring a base, body, and driven sliders with movable driving rods that allow for one-touch operation to selectively open and close fluid pathways between an inlet and discharge pipelines, enabling seamless switching between multiple discharge modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional multi-step switching mechanisms are used to select different water discharge outlets, then reliable outlet selection is achieved, but the operation process becomes complex and cumbersome
Solution Approach 1:
The patent combines multiple independent driving rods into a single integrated driving rod structure. This driving rod simultaneously controls multiple driven sliders to switch between different discharge outlets, reducing the number of operating components from multiple separate switches to a single unified mechanism, thereby simplifying the operation process while maintaining reliable outlet selection
Solution Approach 2:
The single driving rod is designed to perform multiple functions by controlling different driven sliders for different discharge outlets. One driving rod can switch between multiple discharge modes (e.g., shower, rain, massage), making the switching mechanism universal and eliminating the need for separate switching mechanisms for each outlet
2Adaptability or versatility
If multiple through holes are kept open simultaneously for multi-outlet discharge, then discharge flexibility is improved, but fluid leakage between outlets increases
Solution Approach 1:
The patent introduces driven sliders as intermediary components between the driving rod and the through holes. These sliders act as seals that can be positioned to block fluid flow between different outlets. When switching discharge modes, the sliders move to seal off unused through holes, preventing fluid leakage while allowing the selected outlet to remain open
Solution Approach 2:
The switching mechanism uses dynamic movement of driven sliders along the driving rod to control the opening and closing of through holes. The sliders can dynamically adjust their positions to seal or open different discharge paths, enabling flexible mode switching while maintaining fluid tightness between outlets during operation

AI summary
A switching valve includes a base including a bottom wall and a side wall that extends from the bottom wall of the base along a circumferential direction of the bottom wall, a body that can couple to the base to define a cavity between a bottom plate of the body and the bottom wall and the side wall of the base, in which the bottom plate includes two through holes that are each fluidly coupled to the cavity, two sliders disposed within the cavity, and two driving rods each movably coupled to one of the two through holes of the body, in which each driving rod can move relative to the two through holes to block or unblock each respective through hole. Each slider can slide responsive to movement of one of the two driving rods such that only one through hole is unblocked at one time.
