Solution Overview
Problem
Existing swimming pool cleaning robots cannot effectively adjust their position and depth in a liquid environment, limiting their ability to comprehensively clean the pool bottom, walls, and water surface, thereby restricting their application range and operating efficiency.
Innovation Solution
A cleaning device that can be flexibly switched between a position on a liquid surface and under the liquid surface, equipped with a mode switching member, a filtering mechanism, and a drive mechanism to perform underwater and water surface cleaning, utilizing multiple water inlets and outlets to enhance cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning robot is designed to operate only at a fixed position (bottom, wall, or water surface), then the device structure can be simplified, but the adaptability and comprehensive cleaning capability are limited
Solution Approach 1:
The cleaning robot employs a mode switching member with buoyancy adjustment capability that allows dynamic transition between different operational states (underwater, wall-cleaning, water surface). This dynamic design enables the robot to adapt its position and function based on cleaning needs without requiring multiple separate devices, thereby improving versatility while managing structural complexity through integrated design.
Solution Approach 2:
The cleaning robot is designed with multi-functional capabilities to perform underwater cleaning, wall cleaning, and water surface cleaning using the same device. The universal design incorporates interchangeable cleaning components (underwater cleaning component, wall cleaning component, water surface cleaning component) that can be deployed based on the operational mode, allowing one device to serve multiple purposes and positions.
2Productivity
If the cleaning robot uses a single cleaning component, then the device structure is simpler, but the cleaning coverage and efficiency are limited
Solution Approach 1:
The cleaning robot divides the cleaning function into separate specialized components: an underwater cleaning component for bottom cleaning, a wall cleaning component for vertical surfaces, and a water surface cleaning component for surface debris. These segmented components can be selectively deployed based on the operational mode, allowing each component to be optimized for its specific function while maintaining overall system efficiency.
Solution Approach 2:
The cleaning robot dynamically switches between different cleaning components based on the operational mode. The mode switching member controls which cleaning component is active (underwater, wall, or water surface), enabling the system to adapt its cleaning mechanism to the specific task at hand, thereby improving overall cleaning efficiency without requiring all components to operate simultaneously.
3Adaptability or versatility
If the cleaning robot operates only underwater, then the cleaning mechanism is simpler, but the application range is restricted
Solution Approach 1:
The cleaning robot is designed as a universal cleaning device capable of operating in three distinct environments: underwater for bottom cleaning, on walls for vertical surface cleaning, and on the water surface for surface debris removal. This multi-functional design expands the application range significantly compared to single-mode robots, covering the entire pool environment from bottom to surface.
Solution Approach 2:
The mode switching member provides dynamic control over the robot's operational state, allowing transitions between underwater, wall-cleaning, and water surface modes. This dynamic capability enables the robot to adapt to different cleaning scenarios and positions, significantly expanding its application range while managing the complexity of the switching mechanism through integrated design.
