Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging technology is applied to quadruped robots, then convenience and flexibility are improved, but charging efficiency deteriorates due to lack of accurate positioning
Solution Approach 1:
The patent employs feedback mechanisms through detection devices that monitor the charging panel surface condition and provide real-time information to the control system. This feedback enables the robot to adjust its positioning and charging parameters dynamically, resolving the contradiction between wireless charging convenience and charging efficiency by allowing accurate positioning through sensor feedback.
2Device complexity
If wireless charging is implemented without detection mechanisms, then device complexity is reduced, but safety deteriorates due to foreign object interference
Solution Approach 1:
The patent implements preliminary action by using detection devices to scan and identify foreign objects on the charging panel before the wireless charging process begins. This preliminary detection prevents safety hazards from occurring, resolving the contradiction between system complexity and safety by detecting potential issues in advance rather than during charging operation.
3Reliability
If manual wired charging is used, then charging safety is maintained through direct control, but ease of operation deteriorates due to manual intervention requirements
Solution Approach 1:
The patent applies self-service principle by enabling the quadruped robot to autonomously navigate to the charging panel, position itself correctly, and initiate charging without manual intervention. The detection devices and control systems work automatically to ensure safety, resolving the contradiction between charging safety and ease of operation by making the system self-sufficient while maintaining safety protocols.

AI summary
A wireless charging method for an intelligent quadruped robot includes guiding the quadruped robot to the charging panel, detecting a surface condition of the charging panel via the detection device, generating a first signal once a foreign object is present on the charging panel, otherwise, generating a second signal, controlling the charging power supply in a turned-off state when in idle; remaining the charging power supply in the turned-off state based on the first signal; switching from the turned-off state to a turned-on state based on the second signal; and charging a rechargeable battery in the quadruped robot. The method achieves autonomous movement to reduce manual intervention, and prevents charging anomalies or hazards to ensure charging safety.
