Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning is used to clean the water surface profile, then cleaning can be performed, but labor intensity is high and frequent cleaning is required
Solution Approach 1:
The robot swimming pool cleaner autonomously navigates to the water surface profile, positions itself using the gyroscope, and performs cleaning operations without human intervention. The system self-adjusts its attitude angle and cleaning parameters based on sensor feedback, eliminating the need for manual operation while maintaining effective cleaning performance
Solution Approach 2:
The patent replaces manual mechanical cleaning with an automated robotic system that uses sensors (water surface sensors, gyroscope, flow detectors) and controlled mechanisms (adjustable attitude controller, water-draining motor, cleaning roller brush, dirt suction port) to perform cleaning operations, thereby reducing labor intensity while improving cleaning efficiency
2Extent of automation
If existing robot cleaners are used, then automation is provided, but they cannot effectively clean the water surface profile
Solution Approach 1:
The robot equips specialized cleaning components (cleaning roller brush and dirt suction port) specifically designed for the water surface profile geometry, and uses water surface sensors to detect the precise location and characteristics of the profile, enabling effective cleaning of this specific area while maintaining overall automation
Solution Approach 2:
The system dynamically adjusts its attitude angle using the adjustable attitude controller based on gyroscope feedback to maintain optimal contact with the wall surface. The water-draining motor dynamically adjusts the robot's attachment to the wall, and the cleaning parameters are dynamically modified based on real-time sensor data, ensuring reliable cleaning effectiveness throughout the operation
3Manufacturing precision
If the robot adjusts its attitude and position frequently, then complete coverage is achieved, but system complexity increases
Solution Approach 1:
The gyroscope continuously provides feedback on the robot's attitude angle, and the water surface sensors provide feedback on the robot's position relative to the water surface profile. The adjustable attitude controller uses this feedback to automatically adjust the robot's orientation, and the flow detectors provide feedback on cleaning effectiveness. This closed-loop feedback system achieves complete cleaning coverage while managing control complexity through automated feedback-based adjustments
