Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission method (Wi-Fi Miracast) is used to transmit media data, then wireless connectivity is achieved, but the transmission quality is limited due to predetermined data specifications
Solution Approach 1:
The gateway apparatus serves as an intermediary device between the source device and sink device. It receives media data from the source device via wired connection, determines optimal transmission formats based on sink device capabilities and wireless environment, converts the media data accordingly, and transmits it wirelessly to the sink device. This mediator approach enables both wireless connectivity and high transmission quality by bridging the gap between the two devices through intelligent format adaptation.
2Manufacturing precision
If high-definition and high-sound quality content is transmitted, then content quality is improved, but transmission bandwidth requirements increase
Solution Approach 1:
The gateway apparatus dynamically changes transmission parameters including bitrate, resolution, and format based on the sink device's capabilities and the current wireless environment. By obtaining communication performance information and EDID data, the gateway determines optimal parameters that maintain high content quality while adapting the bandwidth consumption to match available transmission capacity, thus resolving the contradiction between quality and bandwidth requirements.
3Manufacturing precision
If media data is transmitted according to sink device output specifications, then output quality is maximized, but compatibility with wireless transmission limitations is reduced
Solution Approach 1:
The gateway apparatus dynamically adjusts media data formats based on real-time assessment of both sink device capabilities and wireless transmission conditions. It obtains communication performance information and environment data to determine the current maximum transmission rate, then converts media data to formats that are both optimal for the sink device output and compatible with wireless transmission limitations. This dynamic adaptation ensures high output quality while maintaining wireless transmission compatibility.
