Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming pool suction devices suffer from low suction force, vortex turbulence, and motor obstruction of water flow due to a single impeller design, leading to inefficient cleaning.
Innovation Solution
A double-impeller leaf collector with a lower and upper impeller component, driven by a transmission structure, forming an axial flow and reducing turbulence, and a motor housed in a protective shell to prevent water interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single impeller is used in the suction device, then the structure is simple, but the suction force is insufficient
Solution Approach 1:
The suction device is segmented into two independent impeller units (first impeller and second impeller) that operate simultaneously. Each impeller has its own motor and suction cavity, dividing the single complex unit into two simpler functional modules that together provide enhanced suction force.
2Device complexity
If a single high-speed impeller rotates, then the structure is simple, but vortex turbulence is generated in the large-diameter suction cavity
Solution Approach 1:
The single large-diameter suction cavity is divided into two separate suction cavities, each associated with its own impeller. This segmentation prevents the formation of large-scale vortex turbulence by creating two smaller, more controlled flow paths.
Solution Approach 2:
The harmful vortex turbulence is extracted and eliminated by separating the single impeller system into two independent systems. Each impeller operates in its own dedicated suction cavity, preventing the cross-interaction that would generate turbulence.
3Device complexity
If the motor is arranged in the flow channel, then the structure is compact, but the motor blocks the water flow, reducing suction efficiency
Solution Approach 1:
The motor is extracted from the flow channel and relocated to a dedicated motor cavity. This separation removes the blocking obstacle from the water flow path, allowing water to flow freely through the suction cavity and impeller assembly without obstruction, thereby improving suction efficiency.
