Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transmission lines or multiple transmitter devices are used to connect multiple displays to an image providing device, then multiple extended frames can be displayed, but the coupling configuration becomes complex
Solution Approach 1:
The patent creates virtual copies of display identification data (virtual EDID) that simulate multiple physical displays. The transmitter device generates and transmits virtual EDID data to the image providing device, allowing the device to recognize and output multiple video streams as if connected to multiple physical displays, thereby avoiding complex physical coupling configurations while achieving multi-frame display capability
Solution Approach 2:
The transmitter device acts as an intermediary between the image providing device and the display. It receives video signals from the image providing device, generates virtual extended display identification data, and transmits this data wirelessly to the receiver device, which then displays the content on the display module. This intermediary approach simplifies the overall system configuration while enabling multiple extended frame display
2Adaptability or versatility
If conventional display application of extended frames is used, then multiple displays can be connected through transmission lines, but screen sharing scenarios in conferences cannot present content of extended frames on a single display
Solution Approach 1:
The patent enables a single display module to perform multiple display functions simultaneously. By transmitting virtual extended display identification data, the system allows the image providing device to output multiple video streams that can be displayed on a single physical display, making the display universal for both traditional multi-display configurations and modern single-display screen sharing scenarios
Solution Approach 2:
The system creates virtual copies of display identification data that allow the image providing device to recognize multiple virtual displays. This enables screen sharing content to be presented on a single physical display while maintaining the functionality of multiple extended frames, thereby improving ease of operation in conference settings
