Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired charging station is constructed on lawn, then charging function is achieved, but vegetation growth is blocked and safety hazards occur
Solution Approach 1:
The patent extracts the charging function from the physical wired charging station structure. By using wireless charging technology, the charging capability is separated from the harmful physical infrastructure (pole pieces, exposed conductors), eliminating vegetation obstruction and safety hazards while maintaining charging reliability.
Solution Approach 2:
The patent replaces the mechanical wired charging system with a wireless electromagnetic field-based charging system. This substitution eliminates the need for physical contact between charging components, removing the harmful effects of exposed pole pieces and wired connections while maintaining effective energy transfer.
2Object-affected harmful factors
If wireless charging is used, then safety and vegetation protection are improved, but alignment between transmitting and receiving ends becomes difficult
Solution Approach 1:
The patent implements self-service alignment through automatic docking mechanisms. The autonomous moving device autonomously navigates to the charging location and aligns its receiving end with the transmitting end without manual intervention. The system uses sensors and control algorithms to automatically achieve optimal positioning, eliminating the need for manual alignment operations.
Solution Approach 2:
The patent employs feedback mechanisms through locating modules and sensors that detect the relative position between the transmitting and receiving ends. The system continuously monitors alignment status and provides real-time feedback to the control module, which adjusts the positioning to achieve optimal charging alignment automatically.
3Measurement precision
If manual alignment is used for wireless charging, then alignment accuracy is improved, but automation is reduced and productivity decreases
Solution Approach 1:
The patent implements automatic docking and alignment systems that eliminate manual intervention entirely. The autonomous moving device independently navigates to the charging station, positions itself accurately using onboard sensors and locating modules, and establishes optimal charging alignment automatically, maintaining both precision and high productivity.
Solution Approach 2:
The patent replaces manual alignment operations with automated electronic control systems. The control module uses feedback from locating modules and sensors to automatically adjust positioning, substituting human-operated mechanical alignment with electronic automation that achieves equivalent or superior precision while dramatically improving charging productivity.
