Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to facilitate the flow of incompressible fluids, such as water, without relying on external energy sources or complex mechanisms, as they often require pressure equalization to maintain fluid flow.
Innovation Solution
A looping water device utilizing atmospheric pressure, compressible fluids, and pressure differences within the device to cyclically move water through a container, barrel body, inlet pipe, and switch valve, with a differential height configuration to leverage gravity and pressure differentials for continuous flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If external energy sources or complex mechanisms are used to facilitate water flow, then fluid flow is maintained, but device complexity and energy consumption increase
Solution Approach 1:
The system uses the water's own weight and the pressure differential created by the height difference to drive circulation. The water flows downward through the inlet pipe due to gravity, compressing air in the barrel body, which then pushes water back up through the vacuum tube, creating a self-sustaining cycle without external energy input
Solution Approach 2:
The invention utilizes pneumatic pressure from compressed air in the barrel body to push water upward through the vacuum tube, and hydraulic pressure from the water column in the inlet pipe to compress the air and drive circulation. This combines gas and liquid pressure mechanisms to achieve flow without external energy sources
2Productivity
If external energy sources are used to maintain water flow, then continuous circulation is achieved, but energy consumption increases
Solution Approach 1:
The circulation system is self-driven by the potential energy stored in the elevated water column and the elastic energy of compressed air. No external pumps or power sources are needed - the system converts gravitational potential energy and pneumatic pressure into continuous kinetic energy for water circulation
Solution Approach 2:
The system changes the pressure parameters naturally through the height differential (15-20 meters). The water column creates hydrostatic pressure that compresses air, which then expands to push water upward, creating a cyclic pressure variation that drives continuous flow without external energy input
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 device achieves continuous water flow with minimal energy input by utilizing natural pressure gradients and gravity, enhancing efficiency and reducing reliance on external power sources.
Implementation Method 1
the water inside the inlet pipe is affected by gravity and tends to flow downwardly
Implementation Method 2
Pressure at the outlet port of the inlet pipe is affected by a weight of the water inside the inlet pipe and the water pressure inside the inlet pipe
Implementation Method 3
the air inside the barrel body is compressed. When the pressure of the air inside the barrel body is larger than the pressure at the water surface in the barrel body, the water inside the barrel body may be pressed out of the barrel body by the air pressure
Implementation Method 4
The atmospheric pressure applied to the water surface in the major tank will keep the differential height between the water surfaces in the vacuum tube and in the major tank at 10 meters
Data Source
AI summary
A looping water device has a container, a barrel body, an inlet pipe, and a switch valve. The container has a major tank and a vacuum tube. A water surface in the major tank approaches a datum plane. The vacuum tube is full of water. The barrel body contains air, is secured inside the major tank, and has a discharge port. The inlet pipe is connected to the barrel body and extends into the vacuum tube. The switch valve is connected between the inlet pipe and the barrel body. The air in the barrel body is compressed by water entering into the barrel body from the inlet pipe. When air pressure exceeds, the water in the barrel body is pushed into the major tank. A differential height between the water surfaces of the vacuum tube and the major tank is kept by the atmospheric pressure.
