Retractable Handle Mechanism for Pool Cleaner Filter Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern swimming pool cleaning robots require users to manually remove and clean the filter, which often results in contact with unhygienic debris, and energy consumption is not optimized.
Innovation Solution
A swimming pool cleaning apparatus with a retractable handle that reduces energy consumption and allows for filter cleaning without direct contact with debris, featuring a handle that moves between positions to facilitate easy filter basket removal and a torsion spring mechanism for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter is made removable for easy cleaning, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The filter device is divided into separable components: the filter basket and the housing. The filter basket can be removed from the housing, allowing users to clean the filter without handling the entire cleaning robot. This segmentation enables easy filter maintenance while keeping the overall device structure manageable through modular design.
2Use of energy by moving object
If the handle is made retractable to improve hydrodynamic profile, then energy consumption is reduced, but the device complexity increases
Solution Approach 1:
The handle is designed as a movable component that can extend and retract. During operation, the handle retracts into a recess in the robot body to minimize hydrodynamic resistance and reduce energy consumption. When needed for filter removal, the handle extends from the recess. This dynamic configuration allows the handle to optimize its position based on operational requirements.
Solution Approach 2:
The handle is pre-positioned in a recess during operation to minimize drag. When filter cleaning is needed, the handle automatically extends from the recess, preparing the user interface for easy access. This preliminary positioning of the handle in different states optimizes both energy efficiency during operation and usability during maintenance.
3Object-affected harmful factors
If the filter basket is made removable without touching debris, then hygiene is improved, but the device complexity increases
Solution Approach 1:
The handle acts as an intermediary tool between the user and the filter basket. Users grasp the handle to manipulate and remove the filter basket without their hands directly contacting the debris inside. The handle serves as a mediator that transfers the user's action to the filter basket while maintaining hygiene by preventing direct hand contact with contaminated surfaces.

AI summary
Swimming pool cleaning apparatus may include a cleaning unit intended to be immersed in a swimming pool and at least one liquid filter circuit between at least one liquid inlet and at least one liquid outlet via a filter chamber removable from the body of the cleaning unit. The filter chamber may include a cover and a filter basket. The cover may include components for fastening the filter basket and locking the filter chamber to the body of the cleaning unit. The locking component may be releasable and, when released, may cause an extraction handle to be deployed from the filter chamber and urged toward a predetermined position.
