Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If image data is transmitted with high compression ratio in poor network environment, then transmission efficiency is improved, but image quality deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of compression ratio based on real-time network state monitoring. The transmitting device continuously evaluates network conditions and adapts the compression ratio accordingly, transitioning from static to dynamic compression strategies to balance transmission efficiency and image quality under varying network conditions
Solution Approach 2:
The patent changes the compression ratio parameter according to network state. When network conditions are good, a lower compression ratio is used to maintain image quality; when network conditions deteriorate, the compression ratio is increased to ensure transmission efficiency, thus dynamically adjusting parameters to resolve the contradiction
2Manufacturing precision
If image data is transmitted with low compression ratio to maintain quality, then image quality is preserved, but network bandwidth consumption increases
Solution Approach 1:
The system dynamically adjusts compression ratio based on real-time network state monitoring. When network conditions are good, a lower compression ratio is used to maintain image quality; when network conditions deteriorate, the compression ratio is increased to ensure transmission efficiency, thus dynamically adjusting parameters to resolve the contradiction
Solution Approach 2:
The patent changes the compression ratio parameter according to network state. When network conditions are good, a lower compression ratio is used to maintain image quality; when network conditions deteriorate, the compression ratio is increased to ensure transmission efficiency, thus dynamically adjusting parameters to resolve the contradiction
3Manufacturing precision
If high-frequency components are preserved in compressed image, then image detail quality is improved, but restoration difficulty increases in poor network conditions
Solution Approach 1:
The patent extracts and selectively transmits high-frequency components based on network conditions. When network state allows, high-frequency components are preserved and transmitted to maintain image detail quality; when network state is poor, these components are omitted or heavily compressed, reducing restoration complexity at the receiving end while maintaining acceptable quality
