Pool Cleaning Robot Docking Using Wall Detection and Self-Climbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pool cleaning robots are cumbersome to remove from water due to their weight, leading to poor user experience and potential damage when manually pulled or requiring high strength to extract using long rods with hooks, which is inefficient and risky.
Innovation Solution
A pool cleaning robot equipped with a gyroscope, driving motor, ultrasonic wave sensors, and a controller enables automatic docking by determining the closest pool wall and adjusting its movement direction to align perpendicular to the wall, allowing it to autonomously move and climb out of the pool without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional pool cleaning robot is manually pulled out of the pool by the user, then the robot can be removed from water, but the user experiences heavy weight burden and potential damage to the robot
Solution Approach 1:
The robot automatically navigates to the pool edge and climbs out independently using its driving wheels and climbing mechanism, eliminating the need for user assistance. The self-service capability allows the robot to handle its own removal from water, resolving the contradiction between ease of operation and robot weight.
Solution Approach 2:
The patent replaces the manual mechanical pulling system with an automated navigation and climbing system. The robot uses ultrasonic sensors for detection, microcontrollers for processing, and coordinated wheel rotation for climbing, substituting the manual mechanical extraction process with an automated electromechanical system.
2Ease of operation
If a cable is used to pull the robot out of water, then the robot can be removed, but repeated pulling actions damage the robot and reduce its service life
Solution Approach 1:
The robot autonomously navigates to the pool edge and climbs out using its own driving mechanism, eliminating the need for external cable pulling. This self-service approach prevents repeated mechanical stress on the robot's cable connections and structural components, thereby maintaining reliability and extending service life.
3Ease of operation
If a long rod with hook is used to extract the robot, then the robot can be pulled out, but high strength is required for the rod and hook, and users must hook the robot accurately
Solution Approach 1:
The robot automatically navigates to the pool edge and climbs out independently, eliminating the need for external extraction tools like long rods with hooks. This removes the complexity of requiring high-strength tools and precise user positioning, as the robot handles its own extraction autonomously.
4Extent of automation
If the robot manually climbs the pool wall, then it can surface automatically, but the climbing mechanism requires precise coordination of multiple components
Solution Approach 1:
The patent combines the navigation, detection, and climbing functions into an integrated automated system. The ultrasonic sensors, microcontroller, and driving wheels work together as a unified climbing mechanism that automatically navigates to the pool edge and climbs the wall, achieving high automation while managing complexity through functional integration.
Solution Approach 2:
The robot uses ultrasonic sensors to detect the pool edge and provides feedback to the microcontroller, which adjusts the wheel rotation and climbing motion in real-time. This feedback mechanism enables precise automated climbing without requiring overly complex mechanical structures, as the control system adapts to actual conditions during the climbing process.
