Drain Conduit Acute Angle Induces Negative Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drainage systems are ineffective in efficiently drawing water from a drainage area into a flowing water body due to the lack of a mechanism to induce negative fluid pressure, which is essential for maximizing water removal, especially during flooding conditions.
Innovation Solution
The drainage system incorporates a drain conduit with a longitudinal axis at an acute angle to the flowing water direction, featuring a conduit discharge opening oriented parallel to the water flow, which induces negative fluid pressure as the flowing water traverses the discharge opening, drawing drainage water from the ground through the conduit and into the water body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional drainage systems are used, then the structure is simple, but the efficiency of water removal is poor
Solution Approach 1:
The patent applies hydraulics by utilizing the flowing water in the water body to create negative fluid pressure through the conduit discharge opening, which then draws drainage water through the conduit. This hydraulic mechanism significantly improves water removal efficiency compared to conventional gravity-dependent drainage systems, while maintaining relatively simple structural elements.
2Productivity
If the conduit discharge opening is oriented parallel to the flowing water direction, then negative fluid pressure is maximized, but the alignment precision requirement increases
Solution Approach 1:
The patent specifies that the conduit discharge opening should be oriented parallel to the flowing water direction, which creates optimal negative fluid pressure conditions. This parameter specification (orientation angle) provides clear manufacturing guidance while achieving maximum water removal efficiency through the resulting pressure differential.
3Productivity
If the conduit is positioned at an acute angle to the flowing water direction, then water removal is enhanced, but the installation complexity increases
Solution Approach 1:
The patent specifies an acute angle between the conduit longitudinal axis and the flowing water direction, which optimizes the negative fluid pressure generation while maintaining reasonable installation feasibility. This parameter specification balances performance enhancement with practical installability, avoiding extreme angles that would complicate construction.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively removes drainage water by leveraging negative fluid pressure, increasing the volume of water removed during high-flow conditions, such as floods, ensuring efficient drainage even when needed most.
Implementation Method 1
the flowing water may induce negative fluid pressure through the conduit discharge opening, the conduit bore and the conduit inlet opening of the drain conduit and in the drain inlet opening, respectively. The negative fluid pressure may draw drainage water from the ground at the drainage area through the drain inlet opening and the conduit inlet opening, the conduit bore and the conduit discharge opening, respectively, of the drain conduit into the flowing water body.

AI summary
Drainage systems for draining precipitation and/or other water from an area to be drained may include a geographical area and a flowing water body As flowing water in the flowing water body adjacently traverses a conduit discharge opening of a drain conduit which communicates with the geographical area and discharges into the water body, the flowing water may induce negative fluid pressure in the drain conduit through the conduit discharge opening. The negative fluid pressure may draw drainage water from the ground at the geographical area through the drain conduit into the flowing water body.
