Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If video games and applications are executed locally on high-performance hardware, then processing capability and graphics performance are improved, but device complexity, power consumption, and cost increase
Solution Approach 1:
The patent extracts the computationally intensive game execution and video rendering functions from the client device and relocates them to remote server systems. The client device retains only lightweight functions for input reception and video display, thereby reducing local hardware complexity while maintaining high processing capability through remote servers.
Solution Approach 2:
The patent introduces a video compression and transmission system as an intermediary between the remote server and client device. The server renders high-quality video, compresses it using specialized codecs, and transmits it to the client, enabling high-performance game execution remotely without requiring the client to have equivalent local processing power.
2Illumination intensity
If video streams are transmitted at high data rates, then video quality is improved, but network bandwidth consumption and transmission time increase
Solution Approach 1:
The patent employs advanced video compression techniques that transform the data representation of video content through parameter optimization. By using efficient compression algorithms and formats, the system achieves high video quality at reduced data rates, transforming the relationship between quality and bandwidth consumption.
3Volume of stationary object
If local storage capacity is increased, then game library and asset storage are improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the storage function for game assets and executables from the client device and relocates it to remote server systems. The client device stores only minimal local data such as user preferences and cached video buffers, while the majority of storage requirements are fulfilled through network-accessible server storage.
4Quantity of substance
If video compression ratio is increased, then bandwidth efficiency is improved, but video quality and decompression complexity increase
Solution Approach 1:
The patent utilizes advanced video compression standards with optimized parameter settings that achieve high compression ratios while preserving video quality. The system employs sophisticated encoding techniques that efficiently represent video content with fewer bits, balancing compression efficiency against quality degradation.
