Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the picture is transmitted intactly to reduce traffic consumption, then the traffic consumption decreases, but the picture quality deteriorates on large-screen terminal devices
Solution Approach 1:
The patent applies local quality by differentiating picture quality based on terminal device type. Small-screen terminals receive high-quality pictures while large-screen terminals receive compressed pictures, optimizing the balance between traffic consumption and picture quality for each specific use case rather than applying a uniform quality level.
Solution Approach 2:
The system dynamically adjusts picture quality based on real-time detection of terminal device characteristics. The server determines appropriate compression levels and quality parameters according to the detected terminal type, enabling adaptive picture transmission that responds to changing conditions.
2Quantity of substance
If the picture quality is reduced to decrease traffic consumption, then the traffic consumption decreases, but the display effect deteriorates on large-screen terminal devices
Solution Approach 1:
The patent implements local quality by tailoring picture compression and quality parameters to specific terminal device categories. Large-screen terminals receive differently processed pictures compared to small-screen terminals, ensuring optimal display effects for each device type while managing traffic consumption.
Solution Approach 2:
The system changes key picture parameters including compression ratio, quality level, and data processing methods based on the detected terminal device type. This parameter adaptation allows the same original picture to be transformed into optimally suited versions for different display scenarios.
3Manufacturing precision
If the picture is transmitted at high quality to maintain picture quality, then the picture quality is maintained, but the transmission speed decreases
Solution Approach 1:
The patent applies local quality by providing high-quality pictures only to small-screen terminal devices where display effects are optimized, while using compressed pictures for large-screen devices. This localized quality approach maintains picture quality where it matters most while improving transmission speed for other scenarios.
Solution Approach 2:
The system dynamically selects picture quality levels based on terminal device detection. The server adjusts quality parameters in real-time according to the detected terminal characteristics, enabling high quality transmission when needed and compressed transmission when speed is prioritized.
4Device complexity
If the same picture is used for different terminal devices, then the picture transmission is simplified, but the display effect deteriorates on large-screen terminal devices
Solution Approach 1:
The patent segments the picture transmission process into different processing paths based on terminal device type. The system divides picture processing into high-quality path for small-screen devices and compressed path for large-screen devices, simplifying the overall system architecture through clear segmentation while optimizing display effects for each segment.
Solution Approach 2:
The system implements local quality by creating device-specific picture versions. Instead of using a single universal picture, the server generates appropriately processed pictures for different terminal categories, optimizing display effects for each local scenario while maintaining manageable system complexity through automated detection and processing.
