Engineering Contradiction Analysis
1Ease of operation
If IP-based Internet structure is used for content transmission, then network device addressing is simplified, but continuous content delivery reliability deteriorates when network device addresses vary
Solution Approach 1:
The patent introduces a content-based routing intermediary that translates between IP addresses and content identifiers. The system uses a content distribution list (CDL) and content routing table (CRT) to mediate between the simplicity of IP addressing and the reliability of continuous content delivery, allowing content to be routed through multiple hops based on content characteristics rather than fixed device addresses.
Solution Approach 2:
The system dynamically adjusts routing paths based on content characteristics and network conditions. The content routing table can be updated in real-time to reflect changing network topology and content popularity, enabling the system to adapt to address variations while maintaining continuous content delivery through flexible multi-hop routing.
2Device complexity
If content is transmitted without priority analysis, then transmission simplicity is maintained, but channel utilization efficiency deteriorates
Solution Approach 1:
The patent changes the transmission parameter from simple binary transmission to priority-based weighted transmission. The content analysis unit extracts multiple parameters (content type, popularity, urgency) and the transmission control device uses these to assign priority levels, enabling efficient channel utilization through priority-driven scheduling while maintaining manageable system complexity through automated parameter extraction and processing.
Solution Approach 2:
The system performs preliminary content analysis and priority assignment before actual transmission occurs. The content analysis unit processes content characteristics in advance, and the transmission control device pre-calculates priority levels and routing paths, allowing for optimized channel allocation and reducing transmission complexity during actual data transfer.
3Device complexity
If simple data center or cache server distribution is used, then system complexity is reduced, but resource waste in wireless network environment increases
Solution Approach 1:
The patent applies local quality by tailoring transmission parameters to specific content characteristics and local network conditions. Instead of uniform distribution, the system adjusts channel selection, priority levels, and routing paths based on the specific content being transmitted and the local wireless network state, minimizing resource waste while maintaining manageable system complexity through localized optimization.
Solution Approach 2:
The system implements feedback mechanisms where the transmission control device monitors network conditions and content transmission effectiveness, adjusting routing decisions and resource allocation in real-time. This feedback loop enables the system to optimize wireless network resource usage dynamically, reducing energy waste while maintaining relatively simple distribution architecture through automated adaptive control.
4Device complexity
If content is transmitted without priority-based channel allocation, then channel assignment simplicity is maintained, but transmission speed and reliability for critical content deteriorate
Solution Approach 1:
The patent segments the transmission process into distinct phases: content analysis, priority assignment, channel allocation, and transmission. This segmentation allows the complex priority-based channel allocation to be broken down into manageable steps, with each phase handling specific tasks independently, thereby maintaining overall system simplicity while achieving fast and reliable transmission for high-priority content through coordinated multi-phase operation.
