Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunctional shower heads have a limited water outlet area due to the fixed surface cover area and spacing of water outlet holes, which affects the comfort of the spray.
Innovation Solution
A multifunctional shower head design that includes a water inlet base and a rotatable water outlet component with a shared water outlet hole and multiple water inlet holes, allowing for increased water outlet area and improved comfort by connecting multiple water inlet holes to a single water chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different kinds of water outlet holes are respectively used for pulse sprays and common sprays, then the spray functions are differentiated, but the water outlet area is small and the comfort of the spray is affected
Solution Approach 1:
The patent merges multiple water inlet holes (first water inlet hole for pulse spray, second water inlet hole for common spray) into a single shared water outlet hole. This allows water from multiple sources to converge and exit through one larger opening, increasing the water outlet area while maintaining functional differentiation through selective plugging of inlet holes
Solution Approach 2:
The single water outlet hole is designed to serve multiple functions by receiving water from different inlet holes corresponding to different spray modes. The outlet hole acts as a universal exit that can output either pulse spray, common spray, or both simultaneously, depending on which inlet holes are opened
2Device complexity
If the area of the surface cover and the spacing of the water outlet holes are fixed, then the structural design is simplified, but the number of water outlet holes is limited and the water outlet area is small
Solution Approach 1:
Instead of increasing the number of separate water outlet holes which would complicate the surface cover design, the patent combines multiple water flows into a single water outlet hole. This maintains the simplicity of the surface cover structure while effectively increasing the total water outlet area through the convergence of multiple inlet streams
3Area of stationary object
If multiple water inlet holes are connected to a single water chamber, then the water outlet area is increased, but the water flow control between different sprays becomes more complex
Solution Approach 1:
The water inlet system is segmented into distinct first and second water inlet holes, each dedicated to a specific spray mode (pulse spray and common spray respectively). The plugging part is also segmented with separate plugging portions for each inlet hole, allowing independent control of water flow to each inlet while they both feed into the same water chamber and shared outlet
Solution Approach 2:
The water chamber acts as an intermediary that receives water from multiple separate inlet holes and delivers it to a single outlet hole. This intermediary chamber simplifies the control mechanism by allowing independent plugging of inlet holes while maintaining a unified outlet, avoiding the need for complex flow distribution systems
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 design effectively increases the water outlet area of various sprays, enhancing the comfort and intensity of the shower experience by ensuring hydraulic output force and preventing water flow from escaping back to other functional sprays.
Implementation Method 1
the elastic member is supported by the water inlet base to push the sealing gasket, so that the sealing gasket is in sealing contact with the first water sealing base
Implementation Method 2
when the water inlet through hole is arranged relative to one water inlet hole, the water inlet through hole is connected with this water inlet hole in a sealing manner

AI summary
A multifunctional shower head includes a water inlet base and a water outlet component. The water inlet base is provided with a water inlet channel, a plugging part and a water inlet through hole. A water outlet component is provided with a water chamber, a water outlet hole and at least two water inlet holes. When the water inlet through hole is arranged relative to one water inlet hole, this water inlet through hole is connected with the water inlet hole in a sealing manner, and the rest of water inlet holes are sealed and plugged by the plugging part. The multifunctional shower head can make the water inlet holes corresponding to each functional spray share the water outlet holes together, resulting that the water outlet area of various sprays can be effectively increased, and then the comfort of the sprays is improved.
