Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard-wired connections are used for data transmission, then signal integrity and bandwidth can be maintained, but mechanical wear and tear and design constraints increase
Solution Approach 1:
The patent replaces mechanical wired connections with electromagnetic field-based wireless communication. The display system uses electromagnetic signals to transmit data between the processing board and display, eliminating physical connectors and wiring that are subject to mechanical wear, thereby maintaining signal integrity while improving mechanical durability.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium for data transmission. Instead of direct physical contact between connectors, electromagnetic waves carry information through air or vacuum, serving as a non-mechanical mediator that eliminates wear and tear while preserving communication reliability.
2Productivity
If hard-wired connections are used for data transmission, then data can be transmitted at full uncompressed resolutions, but design constraints and mechanical limitations increase
Solution Approach 1:
The patent eliminates mechanical connectors and wiring harnesses by using wireless electromagnetic communication. This substitution removes design constraints related to connector form factors, routing complexity, and mechanical assembly, while maintaining high data transmission bandwidth through electromagnetic signal carrying capacity.
3Ease of operation
If mechanical connectors are used to connect devices, then data transmission can be established, but connection speed and flexibility are limited
Solution Approach 1:
The patent replaces mechanical plugging and unplugging operations with wireless electromagnetic connection establishment. The connection is formed instantaneously when devices are within electromagnetic range, eliminating the time required for physical connector insertion and achieving faster connection establishment speed while maintaining ease of operation.
4Adaptability or versatility
If rotatable or removable displays are used, then device versatility is improved, but mechanical durability and signal integrity deteriorate
Solution Approach 1:
The patent replaces mechanical connections in rotatable and removable displays with wireless electromagnetic communication. This allows the display to rotate and move freely without physical wiring constraints, maintaining signal integrity through electromagnetic transmission while preserving configuration flexibility.

Implementation Method 1
transceivers may be used to convert electrical signals to electromagnetic (EM) signals. One transceiver may convert electrical signals to EM signals that are received by another transceiver that converts the EM signals to electrical signals
Implementation Method 2
The electromagnetic communications link can be established within different locations of the same device, or between two different devices

AI summary
Display systems that use contactless connectors for transmitting data are provided. The contactless connectors are electromagnetic connectors that form an electromagnetic communications link. The electromagnetic communications link can be established within different locations of the same device, or between two different devices. The communications link can be established using at least two transceivers. The transceivers can be incorporated in different enclosures that are hinged together, or the transceivers can be incorporated within a hinge that enables two enclosures to move with respect to each other. A transceiver can be incorporated into a display device that can receive data from an active surface that has a transceiver. When the display device is placed on the active surface, the display device may serve as an access point to content contained within the active surface.
