Swimming Pool Robot Airbag Control for Faster Sinking and Floating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming pool robots take a long time to sink and float, reducing their working efficiency due to the method of changing their weight through water absorption and drainage.
Innovation Solution
A controllable sinking and floating swimming pool robot equipped with a sinking and floating control unit, a waterline detection unit, and a main control unit that allows the robot to float and sink by inflating and deflating an airbag with air above the water level, enabling faster and more precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water absorption and drainage method is used to control sinking and floating, then the robot can change its weight to achieve floating or sinking, but the process takes a long time resulting in decreased working efficiency
Solution Approach 1:
The patent uses a buoyancy adjustment chamber that can be filled with or drain water to control the robot's buoyancy. By adjusting the water level in this chamber, the robot can quickly transition between sinking and floating states without the need for complex weight change mechanisms, thereby improving both reliability of control and working efficiency.
Solution Approach 2:
The patent changes the density parameter of the robot by adjusting the water level in the buoyancy adjustment chamber. When water is added to the chamber, the overall density increases causing sinking; when water is drained, density decreases causing floating. This parameter change approach enables rapid response and improves working efficiency.
2Reliability
If water absorption and drainage method is used to control sinking and floating, then the robot can achieve floating or sinking, but the whole process takes a long time
Solution Approach 1:
The patent employs a hydraulic system with a water pump and buoyancy adjustment chamber that enables rapid water transfer. The pump can quickly pump water into or out of the buoyancy chamber, reducing the time required for sinking and floating transitions while maintaining reliable control.
Solution Approach 2:
The buoyancy adjustment chamber is pre-configured with water inlet and outlet channels that are always open or quickly activatable. This preliminary preparation allows the robot to immediately begin the sinking or floating process when commanded, without needing to open valves or activate pumps from a closed state, thus reducing response time.
