Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless power transmission is performed between vehicles without precise positioning control, then the system complexity is reduced, but power transmission efficiency deteriorates
Solution Approach 1:
The system continuously measures the relative position between transmitting and receiving vehicles using GPS and other positioning devices, then feeds this information back to the control unit which adjusts the antenna orientation accordingly. This closed-loop feedback mechanism maintains optimal alignment without requiring complex manual positioning control, resolving the contradiction between system simplicity and transmission efficiency.
Solution Approach 2:
The antenna positioning system automatically adjusts its own orientation based on real-time position data from the vehicles. The control unit autonomously calculates the required antenna angles and actuates the positioning mechanisms without external intervention, enabling the system to self-correct positioning errors and maintain efficient power transmission.
2Loss of energy
If antenna directionality is dynamically adjusted based on vehicle position, then power transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The control unit performs multiple functions: it processes positioning data from GPS receivers, calculates relative vehicle positions, determines optimal antenna orientation angles, and controls the positioning actuators. By consolidating these diverse functions into a single multi-functional control unit, the system achieves high transmission efficiency without proportionally increasing overall complexity.
Solution Approach 2:
The system replaces manual mechanical positioning with automated electronic control. Instead of requiring physical adjustment mechanisms to be manually operated, the control unit uses electronic signals to actuate motors or other positioning mechanisms, substituting complex mechanical intervention with simpler electronic control systems.
3Reliability
If high-precision vehicle positioning is implemented, then power transmission reliability is improved, but manufacturing cost increases
Solution Approach 1:
The system combines multiple existing technologies into an integrated solution: GPS receivers for positioning, communication devices for data exchange, and antenna positioning mechanisms. By merging these separately manufactured components into a unified system, the patent achieves high transmission reliability through coordinated operation while avoiding the need to develop entirely new high-precision positioning hardware from scratch.
