Water Outflow Device Valve Spool Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional water outflow devices with multiple functional sprays require complex rotation mechanisms, leading to wear and leakage issues, especially in larger sizes, which shortens their service life due to high water pressure and mutual wear between components.
Innovation Solution
A water outflow device design featuring a water distribution valve spool and connecting rod system that allows for easier switching between water channels with a fixed water outflow assembly, reducing the need for rotating the entire assembly and minimizing wear, using a switching handle to rotate the spool and dock outlets with inlets, thus lowering the required force and preventing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the water outflow assembly is rotated to switch between water channels, then the water channels can be switched, but wear and leakage occur reducing service life
Solution Approach 1:
The invention divides the water channel switching mechanism into two independent parts: the fixed water outflow assembly and the rotatable water distribution valve spool. Only the small valve spool rotates to align water outlets with water inlets, while the large water outflow assembly remains stationary. This segmentation reduces wear and leakage by minimizing the rotating mass and eliminating rotation-induced gaps between the water outflow assembly and body.
Solution Approach 2:
Instead of rotating the water outflow assembly to switch water channels (conventional approach), the invention inverts the approach by keeping the water outflow assembly fixed and rotating only the water distribution valve spool. This inversion solves the wear and leakage problems caused by rotating the entire assembly.
2Adaptability or versatility
If the water outflow assembly is made larger to accommodate more functions, then more water channels can be provided, but more force is required for rotation and wear increases
Solution Approach 1:
The invention separates the functions of water distribution (fixed water outflow assembly with multiple water inlets) from water channel switching (rotatable valve spool with multiple outlets). This allows the water outflow assembly to be large and accommodate multiple water channels while the switching mechanism remains small and requires minimal rotation force.
Solution Approach 2:
The invention changes the switching mechanism from rotational movement of the entire assembly to a different dimensional approach where only the valve spool rotates. This dimensional change allows the water outflow assembly to maintain its large size for multiple channels while the switching action occurs in a smaller, lower-force dimension.
3Ease of operation
If the water outflow assembly is rotated frequently, then water channels can be switched, but mutual wear between components increases
Solution Approach 1:
By segmenting the system into a fixed water outflow assembly and a rotatable valve spool, the invention minimizes the contact surfaces that undergo wear during switching. The connecting rod transmits rotational force from the handle to the valve spool without requiring the entire assembly to rotate, reducing mutual wear between components.
Solution Approach 2:
The connecting rod acts as an intermediary that transmits the switching force from the handle to the valve spool. This intermediary mechanism allows for controlled, precise rotation of only the necessary component (valve spool) rather than rotating the entire assembly, thereby reducing wear between the water outflow assembly and the body.

AI summary
An easy-to-switch water outflow device includes a body, a water outflow assembly and a water channel switching device. The water outflow assembly is at least capable of spraying out two different functional water sprays; for each of the functional water sprays, the water outflow assembly is provided with at least one water inlet communicating with a water channel of the functional water spray, and the water outflow assembly is provided with a pivoting passage at a position corresponding to the water inflow terminal. The water channel switching device includes a water distribution valve spool, a connecting rod and a switching handle. By rotating the switching handle, the water outlet of the water distribution valve spool can be selectively docked and communicated with the water inlet, thereby realizing the switching of water channels of different functional water sprays of the water outflow device.
