Buoyancy Operating End for Wireless Pool Cleaner Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional swimming pool cleaning robots with wireless communication and battery power supply face difficulties in being removed from the pool due to limited energy, making it challenging for users to extract them from the bottom of the pool, leading to a poor user experience.
Innovation Solution
A movable operating apparatus with a buoyance operating end and electric control lock system that unlocks when the robot stops working, allowing the buoyance end to float and carry a traction rope to the surface, enabling easy removal of the robot by a user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless communication and battery power supply are used to simplify structure, then device complexity is reduced, but ease of operation deteriorates due to inability to easily remove the device from the pool
Solution Approach 1:
The device is divided into two functional parts: the main cleaning robot and a separate buoyancy operating end. The buoyancy operating end can be independently deployed from the robot body via a traction rope, allowing users to easily retrieve the robot from the pool by pulling the floating end, thus solving the removal difficulty without compromising the wireless simplified structure.
Solution Approach 2:
A buoyancy operating end serves as an intermediary element between the user and the cleaning robot. This intermediary component provides a convenient handle for users to grasp and pull the robot out of the pool, eliminating the need for complex hooking operations while maintaining the wireless design simplicity.
2Ease of operation
If battery power supply is used for local power, then ease of operation is improved by omitting cable, but use of energy deteriorates leading to insufficient power for climbing out of pool
Solution Approach 1:
The buoyancy operating end provides upward buoyant force that counteracts the gravitational force on the cleaning robot. This counterweight mechanism enables the robot to be easily pulled out of the pool without requiring additional climbing power from the limited battery, thus preserving energy while maintaining ease of removal.
3Ease of operation
If electric control lock is added to control buoyancy operating end, then ease of operation is improved, but device complexity worsens
Solution Approach 1:
The electric control lock system operates automatically based on the robot's working state. When the cleaning task is completed or battery is low, the system self-activates to unlock and deploy the buoyancy operating end, eliminating the need for manual intervention. This automation provides convenience while keeping the control logic simple and integrated into the existing system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and quick extraction of the automatic pool cleaning device from the pool, enhancing user experience by simplifying the removal process.
Implementation Method 1
The conductor generates a current when a voltage is applied across the conductor by the unlocking signal of the lock control circuit, so as to form a magnetic field acting force on the locking member
Implementation Method 2
the buoyance operating end floats and carries the traction rope out of the accommodation chamber to a water surface

AI summary
The automatic pool cleaning device performs wireless communication and uses a battery. The movable operating apparatus includes: at least one buoyance operating end, an electric control lock, and a locking member. The locking member limits the buoyance operating end when the electric control lock is in a locked state, and removes the limitation when the electric control lock is in an unlocked state. A lock control circuit which unlocks the electric control lock in response to a trigger signal generated when the automatic pool cleaning device stops working, such that the buoyance operating end floats and carries the traction rope out of the accommodation chamber to a water surface. The buoyance operating end is configured to move the automatic pool cleaning device out of a swimming pool in response to a user's operation. The wireless automatic pool cleaning device can be taken out of the pool conveniently and quickly.
