Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional cleaning robots are applied to sloping solar panels, then cleaning automation is achieved, but the robots cannot maintain straight movement and easily deviate from the predetermined path
Solution Approach 1:
The patent implements a feedback control system using magnetic sensors to continuously detect the robot's position relative to the predetermined path. The system compares actual position with target position and automatically adjusts wheel speeds to correct deviations, ensuring the robot maintains accurate path following on sloping surfaces throughout the cleaning operation
Solution Approach 2:
The patent replaces traditional mechanical path following methods with a magnetic field-based guidance system. Magnetic sensors detect the robot's position by sensing magnetic field lines, and the control system uses this information to adjust movement, substituting mechanical precision requirements with electromagnetic field-based positioning and control
2Area of stationary object
If the robot moves on sloping planes, then cleaning coverage is increased, but the robot consumes more energy and has insufficient power for free movement
Solution Approach 1:
The patent implements dynamic speed adjustment based on real-time position feedback. The control system continuously monitors the robot's position relative to the predetermined path and adjusts wheel speeds dynamically, increasing speed when on path and decreasing when correcting deviations, optimizing energy consumption while maintaining cleaning coverage on sloping surfaces
Solution Approach 2:
The patent changes the operational parameters of the robot by adjusting wheel speeds based on position feedback. The system modifies rotation speeds of drive wheels according to the robot's actual position and the required correction, enabling efficient movement on sloping surfaces with optimized energy usage
3Ease of manufacture
If the robot is designed for leveled floors, then manufacturing cost is reduced, but the robot cannot move freely and will slide on sloping solar panels
Solution Approach 1:
The patent replaces mechanical anti-slip mechanisms with a magnetic field-based position detection and control system. Magnetic sensors detect position deviations caused by sliding, and the control system automatically adjusts wheel speeds to correct the deviation, maintaining reliable operation on sloping surfaces without complex mechanical modifications
Solution Approach 2:
The patent implements a feedback control system that continuously monitors the robot's position using magnetic sensors and automatically adjusts wheel speeds to counteract sliding effects on sloping surfaces, maintaining stability without requiring significant mechanical design changes
4Manufacturing precision
If automatic path correction is implemented, then path following accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical positioning mechanisms with a magnetic field-based detection and control system. Magnetic sensors provide position information, and the control system processes this data to adjust wheel speeds, achieving accurate path following with simpler electronic control rather than complex mechanical structures

AI summary
A determining method and control method for straight running of a robot (100) on a slope plane (300), used for determining whether the robot (100) deviates from a set straight path by determining whether a real-time score vector (gxm1) of the acceleration of gravity (g) in the x-axis direction is the same as a standard score vector (gxm0), so as to solve the technical problem that straight running is hard to guarantee as a robot's deviation from a set straight path on a slope plane (300) is hard to find and cannot be corrected in time.
