Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the frame transmission rate is increased to improve image capture capability, then the data rate increases, but bandwidth overload occurs
Solution Approach 1:
The system dynamically adjusts the frame transmission rate based on real-time data rate calculations and bandwidth availability. The processing circuit continuously monitors the data rate of transmitted images and selectively modifies subsequent frame transmission rates to maintain optimal bandwidth utilization, transforming a static transmission parameter into a dynamic adaptive system.
Solution Approach 2:
The patent changes the transmission parameter (frame rate) based on calculated data rate metrics. By computing the actual data rate consumed by image transmission and comparing it against available bandwidth, the system adjusts the frame rate parameter up or down to resolve the contradiction between high productivity and bandwidth constraints.
2Reliability
If image data is transmitted without selective dropping, then image quality is maintained, but bandwidth utilization becomes inefficient
Solution Approach 1:
The system extracts and transmits only the most essential image frames by selectively dropping less critical frames when bandwidth constraints are detected. The processing circuit identifies and removes redundant or less important image data from the transmission stream, maintaining acceptable image quality while significantly improving bandwidth utilization efficiency.
Solution Approach 2:
The patent implements a selective frame dropping mechanism that discards certain image frames based on data rate calculations and bandwidth availability. This allows the system to recover bandwidth resources for more critical transmissions while maintaining overall image sequence quality through intelligent selection of which frames to retain and which to discard.
