Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging is implemented without alignment mechanisms, then the system is simple and easy to operate, but charging efficiency deteriorates when transmitter and receiver are misaligned or too far apart
Solution Approach 1:
The magnetic coupling members enable the transmitter and receiver to automatically align themselves through magnetic attraction forces. The system self-corrects misalignment without requiring manual intervention or complex control systems, maintaining ease of operation while improving charging efficiency through automatic positioning.
Solution Approach 2:
The patent replaces complex mechanical alignment mechanisms with magnetic field-based attraction. Instead of using motors, sensors, and active control systems to achieve alignment, the magnetic coupling members create a passive magnetic field that naturally draws the transmitter and receiver into proper alignment, reducing system complexity while enhancing charging efficiency.
2Loss of energy
If magnetic coupling members are added to achieve automatic alignment, then charging efficiency is improved, but device complexity increases
Solution Approach 1:
The magnetic coupling members serve multiple functions simultaneously: they provide structural attachment between transmitter and receiver, enable automatic alignment through magnetic attraction, and maintain consistent spacing for optimal electromagnetic coupling. This multi-functionality reduces the need for separate alignment mechanisms, thereby improving charging efficiency without proportionally increasing device complexity.
3Ease of operation
If the transmitter and receiver are kept at a distance for wireless charging, then convenience is improved, but charging efficiency deteriorates due to poor coupling
Solution Approach 1:
The magnetic coupling members create a dynamic system where the distance between transmitter and receiver can vary within a magnetic field range. The magnetic attraction maintains optimal coupling strength even when the vehicle moves slightly or is parked at varying distances from the charging station, allowing greater operational flexibility without sacrificing charging efficiency.
