Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming pool cleaning devices with motorized pumps face challenges in handling, removing liquid, and cleaning the filtering device, as they become excessively heavy due to residual water, requiring complex operations and additional outlets for emptying, which complicates user handling and increases costs.
Innovation Solution
A device with a hollow body and filtration chamber that tilts into an emptying position via gravity, allowing liquid to be discharged through pumping outlets, eliminating the need for dedicated emptying outlets and reducing weight, enabling easy removal and transport, and simplifying cleaning operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device uses a motorized pump with filtration chamber, then cleaning performance is improved, but the device becomes excessively heavy due to residual water
Solution Approach 1:
The device separates the filtration chamber from the main body, allowing the filtration system to be removed and cleaned independently. This segmentation enables the filtering device to be extracted without moving the entire heavy device, resolving the contradiction between maintaining cleaning performance and reducing handling weight.
Solution Approach 2:
The filtering device is designed to be extractable from the hollow body, allowing users to remove only the filtration chamber for cleaning purposes. This extraction principle eliminates the need to handle the entire heavy device when cleaning filters, thus reducing the effective weight during maintenance operations while preserving full cleaning performance during operation.
2Ease of operation
If the handle is articulated to allow horizontal transport position, then ease of transport is improved, but the device requires complex emptying operations with dedicated outlets and non-return valves
Solution Approach 1:
The single liquid outlet serves multiple functions: it acts as both the pumping outlet during operation and the emptying outlet during removal. This multi-functionality eliminates the need for separate emptying outlets and associated non-return valves, reducing device complexity while maintaining ease of transport through the articulated handle design.
Solution Approach 2:
Instead of using gravity to prevent water discharge during transport (as in conventional designs), this invention inverts the approach by using the same outlet for both pumping and emptying. The outlet orientation and gravity work together to enable easy emptying when the device is removed, simplifying the emptying operation while preserving transport convenience.
3Ease of operation
If dedicated emptying outlets are provided, then liquid removal capability is improved, but device architecture becomes complex requiring additional non-return devices
Solution Approach 1:
The single liquid outlet performs dual functions as both pumping outlet and emptying outlet. By orienting this outlet appropriately and utilizing gravity, the device achieves effective liquid removal without requiring separate emptying outlets or additional non-return valves, thus maintaining simple architecture while improving liquid removal capability.
Solution Approach 2:
The invention merges the pumping outlet and emptying outlet functions into a single outlet structure. This consolidation eliminates the need for separate emptying outlets and associated non-return devices, reducing architectural complexity while maintaining effective liquid removal capability through proper outlet positioning and gravitational assistance.

AI summary
Detailed is a device for cleaning an immersed surface including a body and members for driving this body over the immersed surface, a filtration chamber which has a liquid inlet and a liquid outlet, a hydraulic circuit for the flow of liquid between the inlet and the outlet through a filtering device, a handle for operating the body which allows a user to carry it in order to immerse it in the liquid or remove it from the liquid, wherein the liquid outlet is arranged at a longitudinal end of the body, and wherein the operating handle is connected to the body at an opposing end so that, when the body is suspended by the operating handle, it tilts spontaneously under the effect of gravity into an emptying position in which the liquid outlet is located below the liquid inlet.
