Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If Wi-Fi interface is used as primary interface for streaming, then high-speed performance is achieved, but network stability deteriorates when Wi-Fi signal becomes weak or unavailable
Solution Approach 1:
The patent combines multiple radio access interfaces (Wi-Fi and cellular) into a unified streaming reception system. The terminal device simultaneously monitors both interfaces and seamlessly switches between them based on network conditions, merging the advantages of high-speed Wi-Fi connectivity with the stability of cellular networks to resolve the contradiction between speed and reliability.
Solution Approach 2:
The patent implements dynamic interface selection and switching mechanisms that adapt to changing network conditions. The system continuously evaluates signal strength, network availability, and streaming quality metrics to dynamically determine which interface to use, transforming the static single-interface approach into a dynamic multi-interface system that maintains both speed and stability.
2Duration of action of stationary object
If adaptive streaming scheme is used to adjust video quality based on bandwidth, then seamless playback is achieved, but user-perceived quality deteriorates due to frequent image quality changes
Solution Approach 1:
The patent performs preliminary buffer filling by pre-loading video segments into the playback buffer using available network bandwidth. This preliminary action ensures that sufficient content is cached before playback begins, allowing the system to maintain stable image quality without frequent adjustments, thus preserving both continuous playback and quality stability.
Solution Approach 2:
The patent changes the control parameter from dynamic quality adjustment to stable quality maintenance. Instead of continuously adapting video quality to bandwidth fluctuations, the system selects an appropriate quality level in advance and maintains it steadily, using network bandwidth variations to fill the playback buffer rather than to adjust quality, thereby eliminating frequent quality changes while ensuring continuous playback.
3Device complexity
If single radio access interface is used for streaming, then device complexity is reduced, but network coverage and service availability deteriorate
Solution Approach 1:
The patent makes the terminal device universally capable of receiving streaming services across multiple network types (Wi-Fi and cellular networks). By equipping the device with multi-interface reception capability and intelligent switching logic, it achieves versatile network coverage without significantly increasing operational complexity, as the switching decisions are automated based on predefined criteria.
