Rotatable Sphere Faucet Diverter for Multi-Spray Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional faucets typically offer only two modes of fluid discharge, stream and shower, which are inefficient at lower flow rates, leading to increased cleaning time and splash-back issues, and lack additional functionality for improved cleaning efficiency.
Innovation Solution
A fluid diverter mechanism with a hollow, rotatable sphere and extended shaft, allowing for multiple spray types/functions, including shower, stream, mist, spray, and jet, aligned in triangular or paralleled formations, with anti-rotation features to maintain position, enabling seamless switching between modes without additional buttons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If stream mode is used for efficient cleaning, then cleaning efficiency is improved, but flow rate becomes restricted and flow becomes gentle and soft
Solution Approach 1:
The fluid diverter mechanism segments the single fluid stream into multiple spray patterns (stream, shower, mist, spray, jet) by directing flow through different pathways within the hollow sphere, allowing users to select between concentrated stream for cleaning efficiency and dispersed patterns for filling tasks without flow rate restrictions
2Force
If shower mode with wide spray pattern is used to increase pressure, then cleaning assistance is improved, but spray splash-back onto unintended areas increases
Solution Approach 1:
The hollow sphere contains localized spray chambers that direct water flow along specific trajectories, creating focused spray patterns that maintain pressure while controlling the direction of water discharge to prevent unwanted splash-back onto surrounding areas
3Device complexity
If conventional two-mode faucet is used, then device simplicity is maintained, but functionality and cleaning efficiency at lower flow rates are insufficient
Solution Approach 1:
The fluid diverter mechanism integrates multiple spray patterns (stream, shower, mist, spray, jet) within a single compact hollow sphere controlled by one rotating handle, enabling the faucet to perform multiple functions including filling, washing, and cleaning with different flow characteristics without requiring separate controls for each mode
4Loss of substance
If water saving mechanisms are implemented to reduce flow rate, then water conservation is improved, but time to fill sinks and pots increases
Solution Approach 1:
The rotating hollow sphere dynamically switches between spray patterns, allowing users to select high-flow patterns like stream or jet for rapid filling tasks and lower-flow patterns like mist or shower for washing tasks, optimizing both water conservation and filling speed based on the specific need

AI summary
An improved fluid diverter mechanisms in fluid control valves for use within faucets, such as kitchen faucets. The fluid diverter mechanisms are aligned in a triangular formation and include a hollow, rotatable sphere with an extended shaft to allow for improved operation of a faucet. The hollow, rotatable sphere includes an entry hole and an exit hole to allow for fluid flow regulation. The hollow, rotatable sphere also includes an anti-rotation feature. The fluid diverter mechanism includes at least two set points, signifying multiple different spray types/functions, to which the mechanism diverts a fluid. In operation, the extended shaft of the hollow, rotatable sphere may be moved to a desired set point, rotating the sphere, which in turn aligns its exit hole with a respective spray delivery line associated with the selected desired set point.
