Showerhead Valve Actuation for Simultaneous Spray Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing showerheads and hand showers with multiple spray types lack efficient control mechanisms for switching between different spray types, often requiring separate valve actuations and not allowing for simultaneous selection changes.
Innovation Solution
A showerhead design featuring multiple directly controllable valves with pushbuttons, where each valve can be independently actuated to control water inflow and optionally coupled valves for additional fluids like air, enabling the creation of various spray types and combinations without the need to deselect existing settings, using a control element for automatic resetting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate valves with separate pushbuttons are used for each spray type, then each spray type can be controlled independently, but the device complexity increases and the ease of operation deteriorates due to multiple separate actuations required
Solution Approach 1:
The patent combines multiple valve actuation functions into a single pushbutton mechanism. When the pushbutton is pressed, it simultaneously actuates multiple valve bodies through a common actuating element, enabling selection of different spray types (water only, air only, mixture) through a single operation rather than requiring separate valve controls for each spray type.
Solution Approach 2:
The single pushbutton serves multiple functions: it can activate water spray, air spray, or their mixture by simultaneously controlling multiple valves. The common actuating element provides universal control for all spray type selections, eliminating the need for separate pushbuttons for each spray mode.
2Adaptability or versatility
If multiple valves are provided for different spray types, then spray type versatility is improved, but the device complexity increases due to multiple valve mechanisms
Solution Approach 1:
Multiple valve bodies are merged into a single integrated valve assembly with a common actuating element. The valve bodies are arranged radially around the actuating element, allowing them to be actuated simultaneously through a single pushbutton while maintaining individual control paths for different spray types.
Solution Approach 2:
The common actuating element serves all valve bodies, providing a universal control mechanism that reduces the number of separate valve actuators needed. This multi-functional design allows one actuating element to control multiple spray types through different valve body configurations.
3Measurement precision
If separate pushbuttons are used for each valve, then direct control of each spray type is achieved, but the ease of operation worsens due to the need to deselect existing settings before selecting new ones
Solution Approach 1:
The patent merges the selection of different spray modes into a single pushbutton action. By pressing the pushbutton, the user simultaneously actuates the appropriate valve bodies to transition between spray types (water, air, mixture) without needing to deselect previous settings, achieving smooth transitions while maintaining precise selection.

AI summary
A showerhead or hand shower with spray outlet openings and at least one valve that controls the inflow of a fluid to the spray outlet openings, wherein the valve comprises a movable valve body via which at least a first and a second valve position are realized. A pushbutton is arranged for controlling the valve and provision is made to provide at least one additional valve for controlling the inflow of a second fluid, which valve is coupled to the at least one valve and is controlled or actuated substantially simultaneously with it through its associated pushbutton.
