Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video data is transmitted without feedback on reception status, then the transmission device can operate independently, but the transmission conditions cannot be accurately set
Solution Approach 1:
The patent implements a feedback mechanism where the display device transmits reception status information (packet reception count, lost packet information) back to the imaging device. This enables the imaging device to accurately measure video quality on the display side and adjust transmission conditions accordingly, resolving the contradiction by introducing controlled feedback complexity to achieve precise measurement.
Solution Approach 2:
The patent replaces complex mechanical quality assessment mechanisms with information-based feedback. Instead of using complex physical measurement systems at the display device, the system uses data transmission and processing (packet counting, status reporting) to achieve accurate quality measurement, substituting physical complexity with information processing.
2Reliability
If video quality is optimized without reception status feedback, then the transmission device operates simpler, but video quality cannot be accurately optimized
Solution Approach 1:
The display device generates feedback information about video reception status including packet reception counts and lost packet information. This feedback is transmitted to the imaging device which uses it to accurately assess video quality and adjust transmission parameters, ensuring reliable video quality through informed control decisions.
Solution Approach 2:
The system enables the display device to self-assess video quality by counting received packets and identifying lost packets. The display device independently generates quality assessment data without requiring external measurement equipment, and this self-generated information is used to control the overall system performance.
3Productivity
If transmission conditions are adjusted without real-time reception information, then the control process is simpler, but real-time video delivery cannot be ensured
Solution Approach 1:
The system establishes a real-time feedback loop where the display device continuously monitors packet reception status and immediately reports back to the imaging device. This enables dynamic adjustment of transmission conditions based on current network state, ensuring real-time video delivery through continuous adaptation rather than static pre-configuration.
Solution Approach 2:
The transmission conditions are made dynamic rather than static. The imaging device continuously adjusts transmission parameters (bit rate, resolution, frame rate) based on real-time feedback about packet loss and reception status. This dynamic adaptation enables the system to respond to changing network conditions and maintain real-time video delivery performance.
