Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a pool cleaning robot is designed to clean only the bottom or only the walls, then the device structure can be simplified, but the application scope and cleaning efficiency are limited
Solution Approach 1:
The moving device is designed with multi-functional capability to perform bottom cleaning, wall cleaning, and water surface cleaning operations. The device can switch between different cleaning modes by adjusting the buoyancy force, allowing a single device to replace multiple specialized cleaning robots, thereby expanding application scope while maintaining reasonable structural complexity
Solution Approach 2:
The device employs a buoyancy force adjustment assembly that can dynamically change the buoyancy force in real-time. This dynamic adjustment enables the device to transition between submerged and floating states, adapting to different cleaning requirements (bottom, wall, or surface cleaning) and improving versatility without requiring multiple fixed-configuration devices
2Ease of operation
If a pool cleaning robot is designed to clean only the water surface, then the device can remain simple and floating, but it cannot perform underwater or bottom cleaning
Solution Approach 1:
The buoyancy force adjustment assembly enables dynamic transition between floating and submerged states. When the device needs to clean the water surface, it maintains a floating state with higher buoyancy force. When bottom or wall cleaning is required, the buoyancy force is reduced to allow the device to submerge, thereby achieving multi-level cleaning coverage while maintaining operational simplicity through a single control mechanism
Solution Approach 2:
The device changes the buoyancy force parameter to adapt to different cleaning tasks. By adjusting the buoyancy force from high (floating for surface cleaning) to low (submerged for bottom and wall cleaning), the device expands its cleaning coverage without complicating the operational interface, as the parameter change is automatically managed by the control system
3Productivity
If the moving device switches position between above and below the liquid surface frequently, then the cleaning efficiency improves, but the position detection and control complexity increases
Solution Approach 1:
The device incorporates sensors that detect the current position (above or below liquid surface) and provide feedback to the control system. Based on this feedback and the cleaning task requirements, the control system automatically adjusts the buoyancy force to achieve the desired position. This closed-loop feedback mechanism enables frequent and accurate position switching while managing control complexity through automated decision-making
Solution Approach 2:
The control system automatically manages the buoyancy force adjustment based on sensor input and cleaning task requirements, without requiring manual intervention. The device self-regulates its position by adjusting buoyancy force in response to detected conditions, enabling efficient position switching while keeping the control system relatively simple through rule-based or algorithmic decision-making

AI summary
The present disclosure provides a moving device used in liquid. The moving device includes a mode switching member configured to achieve a position switching of the moving device above a liquid surface and below the liquid surface. When the moving device is below the liquid surface, the moving device is fully submerged below the liquid surface, and when the moving device is above the liquid surface, at least a portion of the moving device is above the liquid surface.
