Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If path planning or electronic element identification control is used for swimming pool robot navigation, then the robot can achieve accurate position control and thorough cleaning, but the structure becomes complex and costs increase significantly
Solution Approach 1:
The patent extracts the steering function from the complex electronic control system and implements it through a simplified mechanical structure. The water outlet channel is designed with a spiral portion and linear flowing portion that work together to generate steering force, eliminating the need for complex electronic steering components while maintaining position control accuracy.
Solution Approach 2:
The water flow system serves dual purposes: it provides the driving force for robot movement and simultaneously generates the steering force through its specific channel design. The water flow automatically deflects the robot without requiring separate steering control systems, achieving self-service navigation.
2Ease of operation
If multiple electronic components are added for steering and state monitoring, then the robot can achieve precise navigation, but the costs and failure rates increase
Solution Approach 1:
The patent merges the steering function with the water outlet channel structure. The spiral portion and linear flowing portion are integrated into the channel design, allowing the water flow to directly generate steering force on the deflection block without requiring separate steering motors, sensors, or control electronics, thereby reducing failure points.
Solution Approach 2:
The patent uses hydraulic principles by utilizing water flow dynamics to generate steering force. The water flow passing through the spiral portion creates pressure differences that act on the deflection block, providing a reliable, failure-free steering mechanism that eliminates electronic components susceptible to failure.
3Device complexity
If a simple structure is used for the swimming pool robot, then costs are reduced, but the ability to control travelling route is insufficient
Solution Approach 1:
The patent employs curved geometry in the water outlet channel design, specifically the spiral portion that guides water flow to generate rotational steering force. This curved structure enables the robot to navigate efficiently in zigzag patterns, maintaining high cleaning productivity while using only simple mechanical components without complex electronics.
