Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing showers are low in integration, have complex internal parts, and produce inadequate foam, making them inconvenient and not intelligent enough for efficient cleaning.
Innovation Solution
A highly integrated shower design incorporating an inlet tank, first and second electromagnetic valves, an air pump, and liquid pump, which mixes shampoo or shower gel with air and water in a mixing tank to produce fine foam, using independent pipes to avoid odor mixing and enhance cleaning effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional shower design is used, then the structure is simple, but the integration is low and internal parts are complex
Solution Approach 1:
The patent merges multiple functional components (water inlet, mixing chamber, air injection system, liquid pump, electromagnetic valves) into a single integrated shower device. The housing integrates the mixing chamber, while the air pump and liquid pump are combined in one unit, reducing the number of separate parts and simplifying assembly.
Solution Approach 2:
The air pump serves multiple functions: it introduces air into the mixing chamber for foam generation and simultaneously pressurizes the mixing chamber to improve liquid output efficiency. The electromagnetic valves control both water flow and liquid flow through the same device, reducing the need for separate control mechanisms.
2Device complexity
If traditional shower design is used, then the structure is simple, but the foam quality is inadequate
Solution Approach 1:
The patent uses pneumatic principles by introducing air into the liquid through the air pump, creating fine bubbles that mix with the liquid to form high-quality foam. The air injection system utilizes fluid dynamics to generate uniform foam distribution, improving foam quality through pneumatic-liquid interaction.
Solution Approach 2:
The air pump pressurizes the mixing chamber, changing the pressure parameter of the liquid and air mixture. This pressure change enhances the mixing efficiency and foam generation, transforming the physical state of the liquid to produce finer and more uniform foam.
3Reliability
If air pump is added to produce fine foam, then the cleaning effectiveness is improved, but the device complexity increases
Solution Approach 1:
The air pump is designed to perform multiple functions within the shower system: it introduces air for foam generation, pressurizes the mixing chamber to improve liquid output, and enhances the overall mixing efficiency. This multi-functionality justifies the addition of the air pump by providing multiple benefits from a single component.
Solution Approach 2:
The air pump is integrated with the liquid pump and housing structure, combining multiple components into a unified assembly. The air inlet is integrated into the housing, and the pump mechanism is positioned to work in conjunction with the mixing chamber, reducing the overall complexity despite adding functional capabilities.
4Reliability
If independent pipes are used for shampoo and shower gel, then the odor mixing is avoided, but the device complexity increases
Solution Approach 1:
The liquid storage system is segmented into separate containers for shampoo and shower gel, with independent piping for each liquid type. This segmentation prevents odor mixing and allows users to select different liquids without contamination, maintaining reliability through physical separation of fluid pathways.
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 shower produces fine foam efficiently, reduces the number of complex parts, and is easy to assemble, improving cleaning effectiveness while saving on product usage and enhancing water discharge efficiency.
Implementation Method 1
the air pump introduces air into the mixing tank, creating fine foam from the shower gel or shampoo
Implementation Method 2
The air pump also pressurizes the mixing tank, enhancing water discharge efficiency
Implementation Method 3
The second electromagnetic valve serves as the main switch of the liquid path of the shower, and used for controlling the water stoppage and flow through the outlet pipe
Implementation Method 4
When the liquid pump is turned on, the shampoo and shower gel is extracted from the liquid storage tank into the mixing tank to mix with water

AI summary
A shower includes an inlet tank, a first electromagnetic valve, a mixing tank, and a second electromagnetic valve. One end of the inlet tank is provided with an inlet pipe used for communicating with an external water source, the inlet tank, the first electromagnetic valve, the mixing tank, are communicated with the second electromagnetic valve in sequence, the second electromagnetic valve is provided with an outlet pipe; an air pump, one end of which is communicated with the mixing tank, and another end is communicated with the exterior; a liquid pump and a storage tank, the first electromagnetic valve can communicate with or close the inlet tank and the mixing tank, and the second electromagnetic valve can open or close the outlet pipe. The shower gel or the shampoo enter into the mixing tank through two separate pipelines to avoid the mixing of scents.
