Innovation Solution
A vortex water flow accelerator design featuring a joint pipe with an annular and first conical inner surface, a water outlet barrel with a smaller outlet diameter, and spirally bent spiral blades, along with splitter plates and a locking interface, to create a secondary water inlet and minimize resistance, promoting a larger vortex and increased flow velocity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the structure is simplified with only spiral blades, then the device complexity is reduced, but the acceleration effect is insufficient
Solution Approach 1:
The device is segmented into multiple functional components: joint pipe with conical surfaces, water outlet barrel, splitter plates, and spiral blades. Each component performs a specific function - the conical surfaces guide flow, splitter plates create secondary inlets, and spiral blades generate vortex - together achieving superior acceleration effect while maintaining reasonable structural complexity
Solution Approach 2:
The invention adds dimensional complexity by introducing conical surfaces (first and second conical surfaces) and splitter plates that create three-dimensional flow paths. The spiral blades are arranged at specific angles and positions, transforming the simple two-dimensional spiral structure into a multi-dimensional vortex generation system that significantly enhances water flow velocity
2Speed
If the outlet size is reduced, then the flow velocity increases, but the resistance to water flow may increase
Solution Approach 1:
The joint pipe incorporates first and second conical surfaces with optimized curvature radii (R1, R2, R3, R4) that smoothly guide water flow from the inlet to the reduced outlet. These curved surfaces eliminate sharp edges and abrupt transitions, reducing flow separation and turbulence, thereby minimizing resistance while maintaining high velocity through the smaller outlet
Solution Approach 2:
The invention optimizes specific geometric parameters including the outlet diameter (smaller than inlet), conical surface angles, spiral blade pitch angles, and blade thickness variations. These parameter changes are carefully balanced to maximize velocity increase while minimizing resistance - the outlet is reduced in size but not excessively, and the conical surfaces are designed with specific curvature radii to maintain smooth flow
3Speed
If the spiral blade path is extended, then the vortex formation is enhanced, but the device length increases
Solution Approach 1:
The spiral blades are nested within the water outlet barrel, with the blade path optimized to utilize the available radial and axial space efficiently. The blades are arranged in a compact configuration where the spiral path is extended through optimal pitch angle selection rather than simply increasing overall device length, achieving strong vortex formation in a compact form
Solution Approach 2:
The spiral blades are designed with varying thickness (thicker at the root, thinner at the tip) and optimized pitch angles to dynamically adapt to the changing flow conditions along the spiral path. This dynamic design allows the blades to effectively guide water flow through a longer path within the constrained device length, enhancing vortex formation without proportionally increasing the overall dimensions

Function Achieved in This Case
The design significantly increases water flow velocity and vortex formation, enhancing water circulation and filtration efficiency by reducing resistance and extending the spiral blade path, resulting in a larger vortex and higher flow rate.
Implementation Method 1
an inner wall of the joint pipe forms an annular surface and a first conical surface in turn from along a direction from the water inlet to the water outlet... The first conical surface can well reduce the resistance to water flow, so that the flow velocity increases to the maximum
Implementation Method 2
an outer wall of the joint pipe is formed with a second conical surface on which a plurality of splitter plates uniformly distributed at the circumference are formed... The second conical surface also gives the minimum resistance to water flow
Implementation Method 3
a plurality of spiral blades arranged in the water outlet barrel and connected with the joint pipe... the water flows through the spiral blades to form vortex water
