Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water diverter systems for pools and tubs suffer from high energy consumption, significant pressure losses, and inability to generate pulsating water flows due to complex configurations and manual control, which restricts the configuration and efficiency of water distribution.
Innovation Solution
A Y-shaped water diverter apparatus with a motor-driven flow directing member that reduces the distance and angle of water flow changes, minimizing pressure losses and allowing for automatic control, enabling the generation of pulsating water flows with lower energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a T-shaped water diverter is used with manual control at the edge of pools, then water flow direction can be controlled, but significant pressure loss occurs due to 90-degree diversion and long water path from bottom to edge and back
Solution Approach 1:
The patent inverts the conventional T-shaped diverter design by using a Y-shaped configuration where the outlets are positioned at acute angles rather than 90 degrees. This inversion of the geometric arrangement reduces flow separation and turbulence, thereby minimizing pressure losses while maintaining manual control capability
Solution Approach 2:
The patent changes the spatial arrangement from a planar T-configuration to a three-dimensional Y-configuration with outlets oriented at acute angles. This dimensional change in the flow path geometry allows water to diverge more smoothly, reducing energy loss associated with sharp directional changes
2Ease of operation
If a Y-shaped valve with resilient material is used, then flow direction control is achieved, but complex configuration and additional reinforcing means are required
Solution Approach 1:
The patent replaces complex resilient material components with a simpler closing member that can be manufactured from conventional materials. This substitution eliminates the need for additional reinforcing means and reduces manufacturing complexity while maintaining the flow control function
Solution Approach 2:
The patent extracts the resilient material component from the valve design and replaces it with a simpler closing member mechanism. This extraction eliminates the complexity associated with resilient material configuration and the reinforcing means required to support it
3Ease of operation
If a rotor-based Y-shaped valve is used for air flow control, then flow direction is controlled, but the rotor movement is obstructed in water or high-pressure mediums
Solution Approach 1:
The patent replaces the rotor-based mechanical system with a closing member that operates by moving perpendicular to the flow direction. This substitution eliminates the obstruction problem that occurs with rotor designs when used with water or high-pressure mediums, as the closing member does not rely on rotation against the flow
4Ease of operation
If a rotatable closing member valve is used, then water flow direction is controlled, but high forces are required during switching due to intermediate closed state
Solution Approach 1:
The patent allows the closing member to overlap with the outlet during transition, creating a temporary partial closure rather than a complete closure. This partial action during switching prevents the formation of high-pressure differential that would require excessive switching forces, while still achieving effective flow control

AI summary
The invention is a water diverter apparatus comprising—a housing (10) having an inlet section (12) and two outlet sections (14), with a separation angle of less than 180° between the outlet sections (14), and—a flow directing member that can be adjusted by rotation about a shaft (18) supported in the housing (10). The apparatus is characterised in that—the flow directing member is a closing member (16) arranged downstream of the shaft (18), the closing member (16) being connected with the shaft (18) via a spacer (17) and having a closing surface arranged transversely to a flow direction, the closing member (16) having a first position adapted to close one of the outlet sections (14), a second position adapted to close the other outlet section (14), and a third position between the first and the second positions, adapted to allow water to flow into both outlet sections (14). The invention is furthermore a method for operating a water diverter apparatus.
