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 often impractical in settings without power, as they rely on electrical actuation for fluid direction.
Innovation Solution
A flow diverter device with a diverter body and valve stem featuring multiple sealing mechanisms, allowing manual selection between treated and untreated water paths using a mechanical button, ensuring fluid direction to a common outlet without electrical assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a second faucet is installed for treated water output, then fluid selection between treated and untreated water is enabled, but aesthetic appearance and kitchen design are deteriorated
Solution Approach 1:
The patent merges the treated and untreated water outlets into a single faucet assembly. The diverter valve integrates both water streams within one faucet body, allowing users to select between treated and untreated water at a single location rather than requiring separate faucets. This combining approach maintains aesthetic appearance while preserving fluid selection capability.
Solution Approach 2:
The single faucet is designed to perform multiple functions: it can deliver both treated and untreated water through the same outlet. The diverter valve mechanism enables one faucet to serve dual purposes, replacing what would traditionally require two separate faucets, thereby maintaining versatility while improving aesthetics.
2Extent of automation
If electrical actuation is used for fluid direction selection, then automated control is achieved, but reliability in power-independent settings is reduced
Solution Approach 1:
The diverter valve is designed to be manually operated without requiring external power sources. The mechanical actuation system allows users to directly control fluid direction through manual input, making the system self-sufficient and reliable in settings where electrical power may not be available. This eliminates dependence on electrical actuation while maintaining full control capability.
3Reliability
If multiple sealing mechanisms are implemented in the diverter valve stem, then fluid leakage is prevented, but device complexity increases
Solution Approach 1:
The sealing system is segmented into multiple independent sealing mechanisms within the diverter valve stem. Each sealing element addresses specific sealing requirements at different locations or conditions, ensuring comprehensive leak prevention. This segmentation allows complex sealing needs to be met through modular, manageable components rather than a single complex sealing system.

AI summary
A flow diverter device includes a diverter body defining therein a diverter channel that connects with two inlet channels and an outlet channel, and a diverter valve stem including at least two sealing mechanisms. The diverter valve stem is movable between a first position wherein one of the sealing mechanisms engages the diverter channel such that the diverter channel fluidly connects one of the inlet channels with the outlet channel only and a second position wherein another of the sealing mechanisms engages the diverter channel such that the diverter channel fluidly connects the other of the inlet channels with the outlet channel only.
