Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If infrared positioning technology is used for robot navigation, then the robot can detect the charging base position, but the detection range is limited and easily blocked by objects
Solution Approach 1:
The patent introduces wireless signals (WiFi, Bluetooth, Zigbee) as intermediary positioning methods. When infrared detection fails due to distance or obstruction, the robot switches to wireless signal-based positioning to locate the charging base, thereby extending the effective detection range while maintaining reliability.
Solution Approach 2:
The patent changes the positioning parameter from infrared signal detection to wireless signal strength detection. By monitoring signal strength variations and using triangulation algorithms, the robot can determine its position relative to the charging base without being constrained by infrared range limitations.
2Reliability
If infrared positioning technology is used for robot navigation, then the robot can detect the charging base position, but the detection is easily blocked by objects
Solution Approach 1:
The patent uses wireless signals as an intermediary positioning method that can penetrate or bypass obstacles. When infrared signals are blocked, the robot switches to wireless signal-based positioning, which is less susceptible to obstruction by physical objects.
Solution Approach 2:
The patent implements a dynamic switching mechanism between infrared and wireless positioning modes. The robot continuously monitors positioning conditions and adaptively changes the active positioning method based on environmental factors such as obstruction and distance.
3Extent of automation
If the robot uses infrared positioning, then it can locate the charging base, but it cannot automatically return for recharging when far away
Solution Approach 1:
The patent introduces wireless signal positioning as an intermediary method to enable autonomous navigation over extended ranges. By combining wireless positioning with path planning algorithms, the robot can automatically return to the charging base from distant locations where infrared positioning would fail.
Solution Approach 2:
The patent implements preliminary positioning using wireless signals to guide the robot toward the general direction of the charging base before switching to infrared positioning for precise alignment and docking. This two-stage approach enables autonomous operation over extended ranges.

AI summary
A method for guiding a robot includes controlling a wireless signal transmitting device of a charging base to transmit wireless signals, by sending a control signal to the charging base when a battery level of the robot is less than a preset level. Once an orientation of the charging base is determined according to signal strengths of wireless signals detected by at least one signal detecting device of the robot, a moving mechanism of the robot is controlled to drive the robot to move towards the orientation of the charging base.
