Pool Cleaner Winding Mechanism for Automatic Filter Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool cleaning robots require frequent filter maintenance operations, which are time-consuming and difficult due to the need to regularly remove and replace filters while the robot is out of the pool.
Innovation Solution
A pool cleaning robot equipped with a winding mechanism that allows for the automatic replacement of filter portions without removing the robot from the pool, using multiple filter portions that differ in filtering parameters, and a holding mechanism to store and compress filters, along with sensors to indicate when filter replacement is needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a single filter is used in pool cleaning robots, then the device complexity is low, but the duration of action is limited due to frequent manual maintenance
Solution Approach 1:
The filter is divided into multiple replaceable filter portions arranged in sequence. When one filter portion becomes dirty, the winding mechanism automatically advances the next clean filter portion into the filtering position, eliminating the need for frequent manual maintenance and extending the operational duration between maintenance cycles.
Solution Approach 2:
The pool cleaning robot is equipped with a winding mechanism that automatically replaces filter portions without requiring manual intervention. The system self-manages filter replacement by detecting when a filter portion is dirty and automatically winding the next filter portion into position, thereby extending operational duration while managing complexity through automation.
2Loss of time
If manual filter replacement is required, then the device complexity is low, but the loss of time increases due to frequent removal and replacement operations
Solution Approach 1:
The winding mechanism automatically performs filter replacement operations without requiring the robot to be removed from the pool. The system detects when a filter portion is dirty and autonomously winds the next filter portion into the filtering position, significantly reducing maintenance time and eliminating manual intervention.
Solution Approach 2:
The automatic winding mechanism ensures continuous operation by seamlessly replacing filter portions in situ. The transition from one filter portion to the next occurs without interrupting the cleaning operation or requiring the robot to be removed from the pool, thereby minimizing time loss and maximizing operational continuity.
3Quantity of substance
If multiple filter portions are stored in compressed form, then the quantity of substance is optimized, but the device complexity increases due to holding and winding mechanisms
Solution Approach 1:
Multiple filter portions are stored in a compact, nested arrangement within the holding mechanism. The filter portions are wound together in a space-efficient configuration that maximizes the number of filter portions that can be stored within the robot's housing, optimizing the quantity of substance while managing spatial constraints.
Solution Approach 2:
The winding mechanism extracts filter portions from the compressed storage configuration and sequentially positions them in the filtering position as needed. This extraction process allows the system to maintain a compact storage arrangement while providing on-demand access to multiple filter portions, balancing quantity optimization with operational requirements.
