Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming pool cleaning robots are limited in their ability to adjust positions and depth in a liquid environment, resulting in incomplete cleaning of the pool's bottom, wall surfaces, and water surface, thereby restricting their application range and efficiency.
Innovation Solution
A cleaning device that can switch between positions on and under the liquid surface, utilizing a mode switching member with buoyancy and propeller assemblies to adjust vertical forces, sensors for position sensing, and a filtering mechanism to comprehensively clean the pool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cleaning robot is designed to operate only at a fixed position (bottom, wall, or water surface), then the structure can be simplified, but the application range and cleaning coverage are limited
Solution Approach 1:
The cleaning robot employs a mode switching member that enables dynamic transition between different motion states (water surface cleaning, underwater cleaning, and wall cleaning). This dynamic capability allows the robot to adapt its position and function based on cleaning needs, resolving the contradiction between structural simplicity and application versatility by implementing a unified platform with switchable operational modes rather than multiple specialized devices
Solution Approach 2:
The cleaning robot is designed as a multi-functional device that can perform water surface cleaning, underwater cleaning, and wall cleaning operations. The mode switching member enables a single device to fulfill multiple cleaning functions, eliminating the need for separate specialized robots for each cleaning task and thereby expanding application range while maintaining reasonable structural complexity
2Productivity
If the cleaning robot operates underwater only, then cleaning of the pool bottom and walls is effective, but the water surface cleaning capability is lost
Solution Approach 1:
The mode switching member enables the cleaning robot to dynamically switch between underwater cleaning mode and water surface cleaning mode. This dynamic transition capability allows the robot to maintain high underwater cleaning efficiency while also gaining water surface cleaning capability, resolving the contradiction between productivity and adaptability
3Productivity
If the cleaning robot operates on the water surface only, then water surface cleaning is effective, but underwater cleaning capability is lost
Solution Approach 1:
The mode switching member enables bidirectional dynamic operation, allowing the cleaning robot to switch from water surface cleaning mode to underwater cleaning mode as needed. This dynamic capability ensures high water surface cleaning efficiency is maintained while underwater cleaning capability is added, resolving the contradiction between productivity and adaptability
4Device complexity
If the cleaning robot cannot adjust its position in the liquid environment, then the control system can be simplified, but the cleaning coverage of different pool surfaces is incomplete
Solution Approach 1:
The cleaning robot incorporates a mode switching member that enables dynamic position adjustment and motion state transition. This dynamic control capability allows the robot to access and clean different pool surfaces (water surface, underwater, and walls), significantly expanding cleaning coverage while maintaining relatively simple control system architecture through mode-based control
