Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sinking and floating control methods for swimming pool robots are inefficient, taking a long time to change between floating and sinking states, which decreases the robots' working efficiency.
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 accurate control of the robot's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water absorption and drainage method is used to control sinking and floating, then the robot can change its quality to achieve floating or sinking, but the process takes a long time resulting in decreased working efficiency
Solution Approach 1:
The patent uses an airbag component that can be rapidly inflated and deflated to control the robot's buoyancy. The airbag is connected to an air inlet/outlet mechanism that可以快速ly changes the robot's overall density by introducing or removing air, enabling fast transitions between sinking and floating states without the time-consuming water absorption/drainage process
2Productivity
If traditional water absorption and drainage method is used, then the robot can realize floating or sinking by changing its quality, but the configuration of internal components becomes complex
Solution Approach 1:
The patent extracts the buoyancy control function into a dedicated airbag component, separating it from the robot's main body and other systems. This airbag component can be independently inflated and deflated to control sinking and floating, simplifying the overall system architecture by removing the need for complex water absorption/drainage mechanisms and their associated components
Solution Approach 2:
The patent changes the physical state parameter of the airbag (from deflated to inflated) to control the robot's buoyancy. By adjusting the volume of air in the airbag, the robot's overall density changes, enabling it to transition between sinking and floating states. This parameter-based control is simpler than the mechanical water absorption/drainage system
