Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current swimming pool robots sink slowly or fail to reach the bottom due to trapped exhaust gas, leading to inefficient cleaning processes.
Innovation Solution
A swimming pool robot design with a water intake detection module, body state detection module, and dual driving mechanisms that only activate when the robot is submerged, using gravity to sink and then discharge water for propulsion, ensuring efficient dirt suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the motor starts synchronously after the swimming pool robot starts, then the robot is powered to move, but exhaust gas from the motor becomes trapped inside the robot, causing it to sink slowly or fail to reach the bottom
Solution Approach 1:
The patent extracts the harmful exhaust gas from the system by providing a drainage outlet that allows exhaust gas to be discharged from the robot body during the sinking process. The drainage outlet is positioned to enable exhaust gas escape while the robot transitions from water surface to bottom, preventing gas trapping that would otherwise slow sinking or cause floating.
Solution Approach 2:
The patent applies preliminary action by enabling the drainage function to operate during the sinking phase before the cleaning phase. The motor runs initially to power the drainage pump that expels exhaust gas, and only after the robot reaches the bottom and the cleaning phase begins does the drainage function stop. This sequencing ensures exhaust is removed before it can interfere with bottom operation.
2Productivity
If the motor starts before the robot sinks to the bottom, then the robot can be propelled, but the cleaning process becomes inefficient due to extended settling time
Solution Approach 1:
The patent uses preliminary action by pre-positioning the drainage outlet and configuring the control system to enable rapid exhaust discharge during the transition phase. The motor starts briefly to power drainage, then stops once the robot reaches the bottom, eliminating prolonged settling time and getting the robot into productive cleaning operation faster.
Solution Approach 2:
The patent applies dynamics by making the motor operation dynamic rather than continuous. The motor starts to power drainage during sinking, then stops when the robot reaches the bottom. This dynamic control optimizes the balance between propulsion needs and minimizing settling time, improving overall cleaning productivity by reducing idle time at the bottom.
