Rotating Flow Diverter Valve for Single Faucet Water Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water filtration systems require a second faucet for treated and untreated water selection, which is aesthetically undesirable and lacks a non-electrical, mechanical means for fluid diversion.
Innovation Solution
A flow diverter device with a rotatable diverter component and valve body, featuring an annular slot for fluid connection between two inlet channels and an outlet channel, allowing manual selection between filtered and unfiltered water without the need for an additional faucet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a second faucet is installed for treated water output, then fluid selection capability is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The patent combines multiple fluid outlets into a single faucet by integrating a diverter valve that directs treated or untreated water to a common outlet. The valve body includes multiple inlet channels that merge into a single outlet channel, allowing one faucet to dispense different fluid types based on user selection via a mechanical diverter mechanism.
Solution Approach 2:
The single faucet is designed to perform multiple functions by incorporating a diverter mechanism that allows it to deliver either treated water or untreated water through the same outlet. The valve body component with multiple inlet channels and one outlet channel enables this multi-functionality, making the faucet universal for different fluid types.
2Measurement precision
If an electrically actuated selection mechanism is used, then fluid diversion precision is improved, but power dependency increases
Solution Approach 1:
The diverter mechanism is designed to be manually operated without requiring external power sources. The mechanical system uses user-applied force directly to rotate the diverter component, which redirects fluid flow through mechanical means rather than electrical actuation, eliminating power dependency while maintaining functional precision.
Solution Approach 2:
The patent replaces electrically actuated systems with a purely mechanical diverter mechanism. The rotatable diverter component with annular slots and inlet/outlet channels uses mechanical rotation to control fluid flow paths, substituting electrical motors or solenoids with a hand-operated mechanical system that achieves the same diversion function without power consumption.
3Reliability
If multiple separate faucets are used for different fluids, then fluid selection reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple faucet functions into a single integrated device. The valve body component consolidates multiple inlet channels and a single outlet channel with an internal diverter mechanism, replacing the need for separate faucets while maintaining reliable fluid selection through the mechanical diverter system.
Solution Approach 2:
The single faucet device is designed to provide multiple fluid selection options through its multi-functional valve body. The diverter mechanism allows the same outlet to reliably deliver different fluid types (treated or untreated water) based on user input, achieving the reliability of multiple faucets with the simplicity of one device.

AI summary
A flow diverter device includes a valve body component defining therein two inlet channels and an outlet channel; and a rotatable diverter component comprising an exterior side wall and defining therein a connecting channel in the form of an annular slot positioned around a portion of the exterior side wall. The rotatable diverter component is rotatably received by the valve body component and being movable between a first position where the connecting channel fluidly connects one of the inlet channels with the outlet channel only and a second position where the connecting channel fluidly connects the other of the inlet channels with the outlet channel only.
