Detachable Fluid Distributor for Tool-Free Pool Robot Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Parts of pool cleaning robots that are hard to access remain dirtier than easily accessed parts, necessitating improved access for cleaning.
Innovation Solution
A detachable fluid distributor (DFD) is designed for the pool cleaning robot (PCR) that is snap-fit connected to the base, allowing easy detachment and connection without tools, facilitating access to the impeller and filtering unit for cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fluid distributor is permanently fixed to the base, then the structural integrity and sealing are improved, but the accessibility for cleaning critical components deteriorates
Solution Approach 1:
The fluid distributor is segmented into a detachable portion and a fixed base portion, allowing the detachable portion to be removed for cleaning access while the fixed base remains in place. This segmentation enables selective access to critical components without compromising the overall structural integrity of the housing.
2Ease of operation
If the fluid distributor is detachable for easy cleaning access, then the ease of operation is improved, but the risk of improper assembly and leakage increases
Solution Approach 1:
The detachable portion incorporates asymmetric features including a tapered interface and positioning protrusions that correspond to recesses in the base. This asymmetric design ensures that the detachable portion can only be assembled in the correct orientation, preventing improper assembly while maintaining easy detachability for cleaning purposes.
3Ease of operation
If the connection mechanism is simple for tool-free detachment, then the ease of operation is improved, but the connection strength may be compromised
Solution Approach 1:
The connection mechanism transitions from a static permanent connection to a dynamic detachable connection. The resilient portion of the sealing element provides continuous contact force to maintain a leak-proof connection during operation, while allowing easy detachment when needed. This dynamic approach balances connection strength with operational simplicity.

AI summary
A pool cleaning robot (PCR), which includes a housing; a fluid path that comprises an impeller, a filtering unit, a detachable fluid distributer (DFD), a base and one or more output fluid conduits. The filtering unit is configured to filter fluid that entered the fluid path to provide filtered fluid; and the impeller is configured to direct the filtered fluid towards the DFD. The DFD is detachably mechanically coupled to the base, via a connector that comprises a connector DFD portion and a connector base portion; wherein (a) a movement of the DFD in an engagement direction towards the base, and (b) a positioning of the connector DFD portion at a coupling position, lock the DFD to the base.
