Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool cleaning robots lack effective position adjustment in liquid environments, unable to adjust depth for all-round cleaning of pool bottoms, walls, and surfaces, limiting their application scope and efficiency.
Innovation Solution
A pool cleaning robot with a mode switching member that allows flexible switching between positions above and below the liquid surface, utilizing a buoyancy cavity and buoyancy force adjustment to change its position, enabling it to clean all areas of a pool efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pool cleaning robot is designed to clean only the bottom of the pool, then the structure is simple, but the application scope is limited
Solution Approach 1:
The robot employs a dynamic position adjustment mechanism that allows it to transition between different operational positions (bottom cleaning, wall cleaning, and surface floating). The mode switching member enables the robot to change its operational state based on cleaning needs, transforming a static single-function device into a dynamic multi-function system.
Solution Approach 2:
The cleaning robot is designed with universal functionality to perform multiple cleaning tasks: bottom cleaning, wall cleaning, and surface cleaning. The dust box structure serves multiple purposes including filtration, debris collection, and position indication, while the mode switching member enables the robot to adapt to different cleaning scenarios without requiring separate devices.
2Productivity
If the pool cleaning robot can clean both bottom and wall surfaces, then the cleaning coverage is improved, but the device complexity increases
Solution Approach 1:
The robot uses dynamic position adjustment through the mode switching member to transition between bottom-cleaning mode and wall-cleaning mode. This allows a single device to adapt its operational characteristics based on the cleaning target, achieving comprehensive coverage without requiring multiple specialized devices.
Solution Approach 2:
The cleaning robot integrates multiple cleaning functions into a single device that can operate at different positions (bottom and walls). The universal design allows one robot to perform various cleaning tasks throughout the pool, improving productivity while avoiding the need for multiple specialized cleaning devices.
3Adaptability or versatility
If the pool cleaning robot floats on the liquid surface, then the surface cleaning capability is achieved, but the depth adjustment capability is reduced
Solution Approach 1:
The robot employs dynamic position adjustment through the mode switching member that enables transition between floating on the surface and moving along the bottom or walls. This dynamic capability allows the robot to access different depths and positions as needed, maintaining surface cleaning capability while preserving depth adjustment ability through the same mechanism.

AI summary
The present disclosure provides a pool cleaning robot, including: a dust box including a dust box opening. The dust box opening includes: an in-water dust box opening provided on a bottom of the dust box. A process of switching the pool cleaning robot from moving on a bottom wall of a pool to floating on a liquid surface includes at least the following: the pool cleaning robot is first switched from moving on the bottom wall of the pool to moving on a side wall of the pool, and the pool cleaning robot subsequently moves on the side wall of the pool toward the liquid surface; and when the pool cleaning robot moves close to the liquid surface or at least partially above the liquid surface, the pool cleaning robot is switched from being against the side wall of the pool to floating on the liquid surface.
