Swimming Pool Robot Extraction Device with Deployable Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming pool cleaning robots are cumbersome to extract and store, requiring significant user effort and time, especially when the filter needs frequent washing, leading to reduced robot usage due to inconvenience and safety concerns related to water and electricity.
Innovation Solution
A device comprising a support frame with a deployable plate and cable winder that facilitates the extraction of the robot by supporting its weight and managing the cable, allowing for automatic or assisted retrieval and deployment, reducing user intervention and effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a crane with hook is used to extract the robot, then the robot can be hoisted from the pool, but the device complexity increases and requires user presence throughout the operation
Solution Approach 1:
The invention extracts the robot from the pool using a retrieval system that combines a mechanical arm for positioning and a cable winch for extraction. The mechanical arm picks up the robot from the pool surface and positions it over the retrieval bay, while the cable winch then extracts the robot vertically. This separates the extraction function into distinct components rather than using a single complex crane mechanism.
Solution Approach 2:
The retrieval system operates autonomously without requiring continuous user presence. The mechanical arm and cable winch work automatically to extract the robot, and the system can return the robot to the pool automatically as well. This eliminates the need for a user to monitor and control the entire extraction process manually.
2Device complexity
If the robot is extracted manually, then the device complexity remains low, but the time required for extraction increases significantly
Solution Approach 1:
The invention introduces a retrieval bay as an intermediary structure between the pool and the extraction mechanism. The mechanical arm transfers the robot to this intermediate platform, and the cable winch then performs the vertical extraction. This intermediary structure enables automated extraction without requiring complex direct manipulation from the pool environment.
3Reliability
If the robot is extracted frequently for filter cleaning, then the filter can be maintained regularly, but the user effort and time required increases substantially
Solution Approach 1:
The retrieval system operates autonomously without requiring continuous user presence. The mechanical arm and cable winch work automatically to extract the robot, and the system can return the robot to the pool automatically as well. This eliminates the need for a user to monitor and control the entire extraction process manually.
Solution Approach 2:
The mechanical arm performs preliminary positioning of the robot over the retrieval bay before the cable winch begins vertical extraction. This preliminary action prepares the robot for efficient extraction and reduces the overall time required for the operation by having the robot in the correct position before the main extraction force is applied.
4Extent of automation
If a mechanical arm with interface holder is used, then the robot can be moved automatically, but the pool congestion increases due to the interface holder
Solution Approach 1:
The mechanical arm picks up the robot from the pool surface and extracts it to the retrieval bay, removing the robot from the pool environment. The cable winch then completes the extraction vertically. This extracts the robot completely from the pool space rather than requiring it to remain in or near the pool during extraction operations.

AI summary
Devices for extracting cleaning robots from swimming pools include support frames and plates which can be deployed beyond and below the support frames. The support frames may be supported on rims of the swimming pools.
