Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If medical video is encoded before storage, then storage and transmission efficiency is improved, but image quality changes occur that differ from the original video quality
Solution Approach 1:
The system divides the video processing into separate paths: one for real-time monitoring (original video) and one for storage (encoded video with quality adjustment). This segmentation allows encoding to improve storage efficiency while maintaining the option to adjust quality parameters independently.
Solution Approach 2:
The encoder allows dynamic adjustment of encoding parameters (bitrate, resolution, frame rate) to balance between compression efficiency and image quality preservation. Users can modify these parameters in real-time to achieve the desired quality level while maintaining storage benefits.
2Quantity of substance
If encoding is applied to medical video, then data compression and storage capacity are improved, but the visual quality perceived during surgery changes
Solution Approach 1:
The system performs image quality adjustment before encoding, allowing operators to pre-set quality parameters based on the surgical requirements. This preliminary action ensures that the encoded video maintains acceptable quality while achieving the desired compression ratio for storage.
Solution Approach 2:
The system provides real-time feedback by displaying the encoded video alongside the original video, allowing operators to compare quality and adjust encoding parameters accordingly. This feedback mechanism enables continuous optimization of both storage efficiency and visual quality.
3Manufacturing precision
If image quality adjustment is added to the encoder, then image quality consistency is improved, but device complexity increases
Solution Approach 1:
The encoder is designed to perform multiple functions: original video transmission for monitoring, encoding for storage, image quality adjustment, and parameter control. By consolidating these functions into a single device, the system achieves image quality consistency without proportionally increasing overall system complexity.
Solution Approach 2:
The encoder incorporates dynamic adjustment capabilities that allow real-time modification of quality parameters based on user input and video content. This dynamic approach enables the system to adapt to different surgical scenarios and maintain optimal image quality while managing computational resources efficiently.
