Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If all parsing and decoding operations are performed on the video bitstream, then complete video reconstruction and high visual quality are achieved, but power consumption and computational load increase significantly
Solution Approach 1:
The patent applies partial action by selectively performing only necessary parsing and decoding operations based on available power and processing resources. Instead of decoding the entire bitstream, the system identifies and processes only critical portions required to maintain acceptable visual quality, thereby reducing power consumption while preserving essential video functionality
Solution Approach 2:
The system dynamically adjusts the level of parsing and decoding operations based on real-time power availability and processing load conditions. By making operations conditional and adaptive rather than static and complete, the system optimizes the balance between visual quality and power consumption according to current device state
2Loss of information
If comprehensive parsing and decoding operations are performed, then complete video data reconstruction is achieved, but processing time and computational resources are excessively consumed
Solution Approach 1:
The patent implements partial action by performing only essential parsing and decoding operations needed to reconstruct sufficient video information for acceptable playback. Non-critical portions of the bitstream are skipped or processed at reduced fidelity, maintaining functional video output while dramatically improving processing efficiency
Solution Approach 2:
The video bitstream processing is segmented into critical and non-critical portions. The system identifies and processes only the essential segments required for video reconstruction, separating necessary operations from optional ones, thereby improving processing throughput while maintaining adequate video quality
3Manufacturing precision
If high-level video processing operations are performed, then superior visual quality and user experience are achieved, but device power consumption increases reducing battery life
Solution Approach 1:
The patent applies partial action by performing only the minimum necessary processing operations to achieve acceptable visual quality. By avoiding excessive processing of non-essential video portions, the system reduces power consumption and extends battery life while maintaining sufficient video playback quality for user needs
