Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple display modules are coupled with individual power and signal connectors to a backboard, then the display device can be assembled and operated, but the connectors may be damaged or the backboard may need replacement, making manufacturing, inspection, and repair difficult
Solution Approach 1:
The patent replaces mechanical electrical connectors with magnetic coupling fields. Power and signal are transmitted wirelessly through magnetic resonance coupling between transmitter coils in the backboard and receiver coils in each display module, eliminating physical plug-socket connections that can be damaged or loose.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary medium to transfer power and signals between the backboard and display modules. The magnetic coupling acts as a non-contact intermediary that enables energy and data transmission without direct electrical contact, preventing connector damage.
2Ease of operation
If multiple display modules are individually connected to the backboard with connectors, then each module can receive power and signals, but the assembly and repair processes become complicated
Solution Approach 1:
The patent eliminates mechanical connector assembly by using wireless magnetic coupling. The backboard and display modules are positioned near each other, and power/signal transmission occurs automatically through magnetic field coupling, simplifying assembly to just positioning components without plugging or wiring.
Solution Approach 2:
The magnetic coupling system provides automatic alignment and connection. When display modules are positioned near the backboard, the magnetic fields automatically establish the coupling relationship without requiring manual connector insertion or electrical contact establishment, making the system self-aligning and self-connecting.
3Reliability
If physical connectors are used to supply power and image signals to display modules, then connections can be established, but connector damage occurs and replacement is difficult
Solution Approach 1:
The patent replaces fragile mechanical electrical connectors with robust magnetic field coupling. The wireless power and signal transmission through magnetic resonance eliminates wear, contact resistance, and physical damage issues inherent in plug-socket connections, while simplifying manufacturing by removing connector components entirely.

AI summary
Provided is a display device comprising a plurality of display modules and a base module. The base module includes a transmitter configured to transmit a plurality of image signals respectively corresponding to each of the plurality of display modules. A first display module is coupled to the base module to receive the image signals and to transmit at least a subset of the image signals to additional display modules, such as a second display module which is coupled to the first display module to receive the at least a subset of the plurality of image signals from the first display module. The plurality of display modules may be thereby coupled with each other to thus receive and further transmit the image signals to and from other display modules, thereby improving convenience in the manufacture, inspection, and repair of the display device.
