Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external terminals are provided in each device for communication, then communication functionality is achieved, but high-frequency parasitic emission occurs
Solution Approach 1:
The patent merges the communication functions of both devices through magnetic field coupling between antennas. Instead of providing separate external terminals in each device, the system combines the communication capability through the magnetic coupling mechanism, allowing bidirectional communication while eliminating the need for multiple external terminals and reducing parasitic emission.
Solution Approach 2:
The patent introduces magnetic field coupling as an intermediary mechanism between the two devices. The antennas in each device generate magnetic fields that couple with each other, serving as a mediator for data transmission. This intermediary approach replaces direct electrical connections through external terminals, thereby reducing high-frequency parasitic emission while maintaining communication functionality.
2Reliability
If external terminals are provided in each device, then communication is enabled, but electrostatic discharge protection measures are required
Solution Approach 1:
The patent replaces the mechanical/electrical connection system (external terminals) with a magnetic field-based communication system. By using magnetic field coupling between antennas, the system eliminates the need for physical electrical contacts, thereby removing the requirement for electrostatic discharge protection measures while maintaining communication capability.
3Adaptability or versatility
If connection structure allows multiple connection states, then versatility is improved, but structural complexity increases
Solution Approach 1:
The patent implements a dynamic connection structure where the second device can be attached to the first device in multiple different orientations or positions. The magnetic field coupling mechanism maintains effective communication across various connection states, allowing the system to adapt to different usage scenarios without requiring complex switching mechanisms or additional components.

AI summary
An electronic device includes a first device and a second device. The first device and the second device are removably attachable to each other. The first device includes a first front surface, and a first display and a first connection portion arranged at the first front surface. The second device includes a second front surface, a second display arranged at the second front surface, a second rear surface located opposite to the second front surface, and a second connection portion arranged at the second rear surface. The second connection portion is connectable to the first connection portion in a first direction and a second direction opposite to the first direction. In a first connection state in which the second connection portion is connected to the first connection portion in the first direction, the second rear surface is arranged to cover the first display. In a second connection state in which the second connection portion is connected to the first connection portion in the second direction, the second rear surface is arranged not to cover the first display.
