Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Swimming pool robots face challenges in effectively cleaning the waterline and edges due to poor lateral movement and difficulty in maintaining contact with the pool walls, leading to inadequate cleaning efficiency.
Innovation Solution
The swimming pool robot is equipped with a lateral propulsion assembly comprising a lateral flow channel, impeller, and motor, which allows for lateral movement and attachment to the pool walls, combined with a baffle system for efficient liquid management during cleaning and exit modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the swimming pool robot moves laterally along the waterline using a roller brush, then the robot can clean the waterline, but the robot cannot move laterally along the waterline well, leading to poor waterline cleaning effect
Solution Approach 1:
The patent applies hydraulics by using water flow as the propulsion medium. The water inlet introduces water into the flow channel, and the impeller directs this water flow to generate lateral thrust against the pool wall, enabling effective lateral movement along the waterline without relying on traditional mechanical propulsion systems.
Solution Approach 2:
The patent changes the propulsion mechanism from mechanical roller brush movement to hydraulic water flow-based movement. By controlling water flow parameters (inlet position, flow rate, impeller rotation), the system achieves superior lateral movement capability and waterline cleaning effect.
2Productivity
If the swimming pool robot moves along the edge using liquid action force, then the robot can follow the edge, but it is difficult to move along the edge against the wall, leading to poor edge-following cleaning effect
Solution Approach 1:
The patent uses hydraulic principles to generate directed water flow through the flow channel and impeller. This water flow creates controlled thrust force that enables the robot to move along the pool edge and maintain contact with the wall, overcoming the limitation of relying solely on liquid action force.
Solution Approach 2:
The water flow acts as an intermediary medium between the robot and the pool wall. The impeller directs water flow to interact with the wall, generating the necessary force for edge-following movement while maintaining stable contact.
3Productivity
If the robot structure includes a baffle system for liquid management, then cleaning efficiency is enhanced, but device complexity increases
Solution Approach 1:
The patent segments the liquid management function into distinct baffle components (first baffle plate, second baffle plate, third baffle plate) positioned at different locations within the flow channel. Each baffle handles specific water flow control tasks, enabling efficient liquid management during cleaning and exit modes while maintaining relatively simple individual component designs.
