Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for dispensing water into aquifers suffer from significant pressure losses, resulting in low flow velocity and limited distribution, leading to ineffective water dispersion and restricted flow rate.
Innovation Solution
An infiltration head with a deflector and strategically positioned apertures that gradually change the water flow direction, reducing turbulence and pressure losses, allowing for higher flow rates and broader dispersion into the aquifer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water is supplied through slots in a slotted pipe, then water can be dispensed into the aquifer, but the water flow is subjected to large pressure loss resulting in low flow velocity and limited dispersion area
Solution Approach 1:
The infiltration tube is segmented with multiple apertures distributed along its length, allowing water to be dispensed at multiple locations rather than through a single slot system. This segmentation reduces the flow resistance at each aperture while maintaining overall dispersion effectiveness.
Solution Approach 2:
The invention transitions from a two-dimensional slot system to a three-dimensional aperture distribution along the tube length. Water is dispensed radially through apertures at different axial positions, creating conical cavities that extend vertically and horizontally, thereby increasing the effective dispersion volume and reducing pressure loss.
2Area of stationary object
If water is ejected through slots at low flow velocity, then pressure loss is reduced, but the water is only dispensed in a small area around the slotted pipe resulting in ineffective water dispersion
Solution Approach 1:
The deflector is positioned upstream of the apertures to preliminarily redirect the water flow before it reaches the discharge points. This preliminary action ensures that water approaches the apertures with optimized direction and velocity, enabling effective penetration into the aquifer without requiring excessive flow velocity.
Solution Approach 2:
The invention changes the flow parameters by using a deflector to modify the flow direction and velocity distribution before water reaches the apertures. This parameter optimization allows water to be dispensed at sufficient velocity to create conical cavities while maintaining energy efficiency.
3Loss of energy
If a deflector is added to gradually change flow direction towards apertures, then turbulence and pressure losses are reduced, but the device complexity increases
Solution Approach 1:
The deflector acts as an intermediary element between the water supply and the apertures. It mediates the flow transition by gradually redirecting water toward the aperture centers, reducing turbulence and pressure loss without requiring complex flow control mechanisms.
Solution Approach 2:
The deflector is strategically positioned only at specific locations where flow redirection is most needed, rather than throughout the entire tube. This localized approach minimizes the added complexity while achieving the desired flow optimization at critical points.
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 solution enables water to be dispensed into the aquifer at higher flow rates and over a larger area, forming conical cavities that enhance penetration depth and reduce backflow, ensuring effective and even distribution.
Implementation Method 1
disturbances in the water flow can be reduced or prevented. Therefore, turbulence in the water flow within the infiltration pipe
Implementation Method 2
When water is introduced via the pipe into the nozzle filter filled with groundwater a spherical pressure wave occurs due to the water resistance
Implementation Method 3
the cavities have a substantially conical shape, tapering outwards away from the one or more apertures, due to the pressure difference over each of the one or more apertures
Implementation Method 4
the suction tension or the wineskin effect occurs, which sucks the rainwater from the nozzle filter into the outflow of the aquifer
