Faucet Diverter Control Mechanism Eliminates Spring Fatigue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Faucet diverters with existing control mechanisms suffer from elastic fatigue, leading to incomplete water channel closure and water leakage due to accumulated pressure, as the ball mechanism used for switching water flow paths loses effectiveness over time.
Innovation Solution
A faucet diverter design featuring a control part with a valve, disc, and operation member that allows for smooth direction switching of water flow, incorporating a first and second rotary member assembly for 180-degree rotation of the outlet head and a baffle plate with spray holes, enabling water flow to be directed through multiple channels or stopped, thus preventing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a ball mechanism with spring is used to switch water flow paths, then the control function is simple, but elastic fatigue occurs over time causing incomplete channel closure and water leakage
Solution Approach 1:
The patent removes the spring component from the ball mechanism, extracting the source of elastic fatigue. The ball is no longer spring-loaded but instead relies on water pressure and gravity for operation, eliminating the reliability issue caused by spring degradation over time.
Solution Approach 2:
The ball mechanism is redesigned to be self-regulating without external spring force. The ball automatically positions itself based on water pressure differential and gravity, closing the channel when pressure equalizes and opening when pressure differential exists, eliminating the need for spring maintenance.
2Power
If water pressure accumulates in the water channel during discharge, then the water flow force increases, but the accumulated pressure pushes the ball causing water leakage in the closed channel
Solution Approach 1:
Instead of using spring force to push the ball against pressure, the design inverts the approach by allowing water pressure itself to control the ball position. The ball closes the channel when pressure equalizes on both sides, and the accumulated pressure naturally opens the channel when needed, turning the pressure problem into the control mechanism.
3Reliability
If a valve with disc and operation member is added to control water flow direction, then water leakage is prevented, but the device complexity increases
Solution Approach 1:
The patent combines the ball mechanism and valve disc into a single integrated control assembly. The ball operates within the valve body and directly controls the disc position, merging two control functions into one unified mechanism that reduces overall complexity while maintaining reliable flow direction control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The improved control mechanism ensures reliable and leak-free operation by allowing precise control over water flow direction, reducing elastic fatigue and preventing water leakage through enhanced channel switching and sealing capabilities.
Implementation Method 1
The operation member is connected to the cylindrical part by threads, able to rotate and unable to move along the axial direction. When the operation member is rotated, it pushes the cylindrical part to move axially.
Implementation Method 2
the ball on the cylindrical part is leaning against by a spring
Implementation Method 3
a water pressure is accumulated in the water channel while the water flow is discharged. The water pressure accumulated also pushes the ball.
