Solution Overview
Problem
Existing underwater robots for swimming pool cleaning require manual intervention for operation, which is inconvenient and limits their effectiveness.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control is used for underwater robots, then operation control is simplified, but convenience for operators and operational efficiency deteriorates
Solution Approach 1:
The underwater robot is equipped with liquid level sensors that automatically detect water entry and trigger the driving mechanism without manual intervention. The robot autonomously activates its impellers and begins cleaning operations when submerged, eliminating the need for operators to manually control startup sequences while maintaining simple operation through automatic water-detection-based activation.
2Measurement precision
If sensing structure is exposed to water for direct detection, then detection accuracy is improved, but reliability and service life deteriorate due to water contact
Solution Approach 1:
The liquid level sensors are installed inside the sealed cabin rather than directly exposed to water. The sealed cabin acts as an intermediary barrier that protects the sensing structure from water contact while still allowing the sensors to detect water entry through changes in the sealed environment, thus maintaining detection accuracy without compromising reliability or service life.
3Reliability
If trigger mechanism is sealed to protect components, then reliability is improved, but ease of maintenance and repair deteriorates
Solution Approach 1:
The trigger mechanism is divided into modular components including the sealed cabin, liquid level sensors, and driving mechanism with distinct functional sections. The sealed cabin can be independently accessed and maintained without disassembling the entire robot, allowing technicians to service the sensing and control components while maintaining the seal integrity of water-sensitive areas.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The autonomous operation significantly improves the convenience and efficiency of swimming pool cleaning, as the robot can move and clean the pool bottom independently, reducing the need for manual intervention.
Implementation Method 1
the sensing structure include liquid level sensors that are disposed in the sealed cavity and sense whether the underwater robot enters the water without being in contact with the water
Implementation Method 2
two impellers both disposed in the region between the sealed cabin and the housing, wherein one of the impellers is connected to the output shaft of one of the motors, and the other impeller is connected to the output shaft of the other motor; and after the underwater robot enters water and triggers the sensing structure, the sensing structure is configured to trigger one of the motors to work and drive the corresponding impeller to rotate, so that the water in the cavity flows out from the first water outlet or the second water outlet
