Find Innovative SolutionsGenerate Solutions
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 bottom, wall surfaces, and water surface, thereby restricting their application range and operating efficiency.
Innovation Solution
A cleaning device with a buoyancy adjustment assembly that allows flexible switching between positions on and under the liquid surface, equipped with a filtering mechanism, drive mechanism, and movement propulsion, enabling underwater and water surface cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning robot operates only at a fixed position (either on water surface or underwater), then the device structure can be simplified, but the application range and cleaning coverage are limited
Solution Approach 1:
The patent implements a buoyancy adjustment assembly that enables the cleaning robot to dynamically change its buoyancy state, allowing it to switch between floating on the water surface and submerging underwater. This dynamic adaptability resolves the contradiction by enabling the robot to operate in multiple positions (water surface, water column, bottom) without requiring multiple separate devices, thus expanding application range while maintaining a unified device structure.
2Productivity
If the cleaning robot is designed to clean only one specific area (bottom, wall, or water surface), then the device can be optimized for that specific function, but the operating efficiency and comprehensive cleaning capability are reduced
Solution Approach 1:
The patent designs a multi-functional cleaning robot that can perform cleaning operations on the water surface, in the water column, and on the bottom of the pool. The buoyancy adjustment assembly enables the robot to access all these areas, making it a universal cleaning device that replaces multiple specialized devices, thereby improving operating efficiency and comprehensive cleaning capability.
3Adaptability or versatility
If the cleaning robot cannot adjust its depth position flexibly, then the device structure and control system can be simplified, but the ability to comprehensively clean different areas of the pool is limited
Solution Approach 1:
The patent employs a buoyancy adjustment assembly that utilizes pneumatic or hydraulic principles to control the robot's depth position. By adjusting the volume of air or fluid in buoyancy chambers, the robot can flexibly change its buoyancy and achieve different depth positions (surface floating, mid-water suspension, and bottom contact), providing comprehensive position adjustment capability through a relatively simple control mechanism.
