Solution Overview
Problem
Existing swimming pool cleaning devices face challenges such as high energy consumption, complex hydraulic circuits, and inconvenient access to the filtering device, which increase costs and reduce user comfort and performance.
Innovation Solution
A device with a filtration system comprising two shells that form an integral filtering casing, allowing easy removal and cleaning without tools, featuring a debris recovery pocket and a liquid inlet conduit that eliminates the need for non-return valves, and a simplified hydraulic circuit with a pumping device for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the access flap is located at the base of the hollow body, then the filtering device can be accessed, but the device must be inverted which may damage it and cause untimely liquid flow
Solution Approach 1:
The access flap is relocated from the base to the upper portion of the hollow body, inverting the conventional arrangement. This allows the filtering device to be accessed without inverting the entire cleaner, eliminating the risk of damage and untimely liquid flow while maintaining ease of operation.
2Ease of operation
If the access flap is arranged above the device, then access is improved, but the hydraulic circuit becomes complex requiring a powerful pumping device that consumes energy
Solution Approach 1:
The filtering device is segmented into a first shell (debris recovery pocket) and a second shell (liquid inlet conduit) that can be separated. This segmentation simplifies the hydraulic circuit by eliminating the need for complex valve arrangements, reducing energy consumption while maintaining ease of access via the upper access flap.
Solution Approach 2:
The second shell with the liquid inlet conduit is extracted as a separate removable component. This extraction simplifies the overall hydraulic circuit design, eliminating the need for powerful pumping devices and complex valve systems, thereby reducing energy consumption.
3Ease of manufacture
If the filtering device is designed as an integral unit, then it is simple to manufacture, but it is difficult to remove and clean without tools
Solution Approach 1:
The filtering device is divided into two shells that can be separated without tools. The first shell forms the debris recovery pocket and the second shell forms the liquid inlet conduit. This segmentation maintains manufacturing simplicity while enabling easy tool-free disassembly for cleaning and maintenance.
4Reliability
If non-return valves are installed at liquid inlets, then liquid flow control is improved, but the device complexity increases and cost increases
Solution Approach 1:
The second shell with the liquid inlet conduit is extracted as a separate component that can be removed and cleaned independently. This extraction eliminates the need for non-return valves at the liquid inlets, simplifying the hydraulic circuit and reducing device complexity while maintaining reliable liquid flow control through the removable inlet conduit design.
