Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent robot charging systems face issues with reliable docking due to the walking mechanism becoming disengaged after voltage or current detection, leading to potential power and charging failures.
Innovation Solution
An intelligent robot system with a docking electrode, walking mechanism, and control unit, where a locking actuator is activated upon successful docking to secure the walking mechanism, using a braking device or motor with brake coil to prevent disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the walking mechanism is left in free state after voltage detection, then the robot can move freely, but the docking electrode may separate from the charging electrode causing power failure
Solution Approach 1:
The patent applies preliminary action by detecting voltage or current on the docking electrode before the motor drives the walking mechanism, and then proactively locking the walking mechanism in a locked state. This prevents the potential separation problem before it can occur, ensuring reliable docking while maintaining the ability to move freely when needed.
2Reliability
If the walking mechanism is locked after docking, then charging reliability is improved, but the robot loses movement capability
Solution Approach 1:
The patent applies dynamics by making the walking mechanism's state changeable between locked and free states based on operational needs. The control unit transitions the mechanism from a free state during movement to a locked state during charging, and back to free state after charging completes. This dynamic state management resolves the contradiction between maintaining charging reliability and preserving movement capability.
3Measurement precision
If voltage detection is used to judge successful docking, then the docking status can be detected, but the walking mechanism may still move causing separation
Solution Approach 1:
The patent applies feedback by using the control unit to continuously detect voltage or current on the docking electrode, and based on this detection feedback, automatically control the motor to lock the walking mechanism. This closed-loop feedback system ensures that the walking mechanism remains locked during charging as long as successful docking is detected, preventing separation and ensuring charging continuity.

AI summary
An intelligent robot system comprising an intelligent robot (100) and a charging base (200). The intelligent robot (100) comprises a docking electrode (102), a walking mechanism (106) and a control unit (105). The docking electrode (102), the walking mechanism (106) and the control unit (105) are disposed in the body (101) of the intelligent robot (100). The charging base (200) comprises a charging electrode (201) disposed on the body (101) of the charging base (200). The intelligent robot (100) further comprises a gripping mechanism (107). When the docking electrode (102) and the charging electrode (201) dock successfully, the control unit (105) controls the e gripping mechanism (107) to lock the walking mechanism (106) to enable the intelligent robot (100) to maintain a successful docking state in the charging base (200), preventing the charging electrode (201) of the charging base (200) from being separated from the docking electrode (102) due to the improper movement of the walking mechanism (106). Any interference during of the intelligent robot (100) is thus prevented and charging efficiency is improved.
