Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for liquid environments, such as swimming pools, fail to effectively regulate their position and depth to clean the bottom, wall surface, and liquid surface in an all-round manner, limiting their application scope and efficiency.
Innovation Solution
A swimming pool robot with a liquid intake portion, including a first intake at the bottom and a second intake at the side, allows for flexible switching between motion states to clean the bottom, side wall, and liquid surface, utilizing a mode switching member with a buoyancy cavity and pump to adjust buoyancy for position-and-posture changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning device is designed to clean only the bottom or only the wall surface, then the device structure can be simplified, but the cleaning coverage and application scope are limited
Solution Approach 1:
The cleaning device is designed with multi-functionality to perform bottom cleaning, wall surface cleaning, and liquid surface cleaning through different motion states. The device incorporates both a first motion state for bottom cleaning and a second motion state for wall surface cleaning, enabling it to handle multiple cleaning tasks with a single device, thereby improving cleaning coverage without requiring separate specialized devices for each function.
Solution Approach 2:
The cleaning device employs dynamic motion state switching between bottom-moving state and wall-climbing state. The device can transition between these states based on cleaning needs, allowing it to adapt to different cleaning scenarios. This dynamic capability enables the device to access different areas of the liquid environment (bottom, walls, surface) and perform comprehensive cleaning while maintaining a relatively compact and manageable structure.
2Productivity
If the cleaning device cannot regulate depth and position, then the device control system can be simplified, but the cleaning efficiency and work effectiveness are limited
Solution Approach 1:
The cleaning device incorporates dynamic depth and position regulation capabilities, allowing it to adjust its vertical position between bottom, wall, and surface levels. The device can switch between different motion states (bottom-moving, wall-climbing, surface-floating) based on real-time cleaning needs, enabling comprehensive coverage of the liquid environment. This dynamic positioning improves cleaning efficiency by ensuring the device can access all necessary areas without requiring an overly complex control system.
Solution Approach 2:
The cleaning device is designed with autonomous depth and position regulation capabilities, where the device can independently determine and adjust its own position based on cleaning requirements. The device uses sensors and control algorithms to automatically transition between motion states and regulate its depth, reducing the need for external manual intervention or complex external control systems. This self-service capability improves cleaning efficiency while keeping the control system manageable.
3Adaptability or versatility
If the cleaning device uses a single intake port, then the device structure can be simplified, but the cleaning functionality for different surfaces is limited
Solution Approach 1:
The cleaning device is equipped with multiple intake ports positioned at different locations (bottom intake port and side intake port) to correspond with different cleaning functions. The bottom intake port is specifically designed for bottom cleaning, while the side intake port is designed for wall surface cleaning. This segmentation of intake ports allows each port to be optimized for its specific cleaning function, improving overall cleaning functionality while maintaining relatively simple individual port structures.
Solution Approach 2:
Different intake ports are provided with different local characteristics and configurations suited to their specific functions. The bottom intake port has structural features optimized for capturing debris from the bottom surface, while the side intake port has features optimized for capturing debris from wall surfaces. This local quality differentiation allows each intake port to perform its specific function effectively without requiring complex universal intake structures.

AI summary
A swimming pool robot and a method for controlling a swimming pool robot are disclosed. The swimming pool robot includes a liquid intake portion including at least a first intake and a second intake. During a process of switching the swimming pool robot from a first motion state to a third motion state, the swimming pool robot is first switched from the first motion state to a second motion state and subsequently switched from the second motion state to the third motion state. No matter whether when the swimming pool robot is in the first motion state or when the swimming pool robot is in the third motion state, the first intake faces a bottom of a swimming pool, and/or a posture of the swimming pool robot in the first motion state is substantially identical to the posture of the swimming pool robot in the third motion state.
