Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower systems require users to manually squeeze bottles of shower gel, making the application of fluid mediums during showering tedious and inconvenient.
Innovation Solution
A device integrating a water pipe assembly, a fluid medium pipe assembly with a suction pipe and a one-way valve, and a water jet pump with a three-way valve, allowing for the controlled suction and mixing of fluid mediums with water, which are then supplied through the shower system without manual handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual squeezing of shower gel bottle is used, then the application of fluid medium can be achieved, but the operation process becomes tedious and troublesome
Solution Approach 1:
The system enables self-service operation where the shower gel automatically mixes with water through the water jet pump without requiring manual squeezing. The fluid medium is drawn from the reservoir and injected into the water flow automatically, allowing the system to serve itself rather than requiring user intervention for each application.
Solution Approach 2:
The manual mechanical action of squeezing the bottle is replaced by a hydraulic system. The water jet pump uses water pressure to draw the fluid medium from the reservoir and inject it into the water flow, substituting the manual mechanical squeezing action with an automated hydraulic mechanism.
2Extent of automation
If water jet pump is used to suction and mix fluid medium, then the automation of fluid medium supply is improved, but the device structure becomes more complex
Solution Approach 1:
The water jet pump serves multiple functions: it draws water from the water supply, creates negative pressure to suction the fluid medium from the reservoir, mixes the two fluids together, and delivers the mixed flow to the shower system. This multi-functionality reduces the need for separate components for each operation, thereby limiting the increase in device complexity despite achieving high automation.
Solution Approach 2:
The system uses hydraulic principles where water pressure from the supply is converted into a vacuum effect to draw the fluid medium, and then the mixing is achieved through hydraulic flow. This hydraulic approach allows automation without requiring complex mechanical or electrical systems, maintaining relative simplicity while achieving high automation.
3Reliability
If one-way valve is installed to prevent backflow, then the reliability of fluid medium delivery is improved, but the device structure becomes more complex
Solution Approach 1:
The one-way valve is a simple, inexpensive component that can be easily integrated into the system. While it adds a component to the structure, the valve itself is simple in design and can be replaced if needed, making the complexity increase minimal compared to the significant reliability improvement it provides for preventing backflow.
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
Enables easy and convenient control of fluid medium supply during showering, preventing backflow and ensuring reliable delivery of the medium to the user's skin, enhancing user experience and simplifying the application process.
Implementation Method 1
a negative pressure is generated in the water inlet pipe of the water jet pump, thereby controlling the fluid medium to be sucked from the fluid medium inlet of the suction pipe
Implementation Method 2
The three-way valve pipe includes a venturi nozzle. The water inlet pipe, the water return pipe and the water mixing pipe meet at a center, and the venturi nozzle is provided between the water inlet pipe and the center.
Implementation Method 3
a valve body assembly including a one-way valve for preventing back flow of the liquid medium
Implementation Method 4
The fluid medium is mixed with the water flowing into the water inlet pipe of the water jet pump in the water mixing pipe of the water jet pump, and then flows into the shower system via the water outlet
