Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple links operate simultaneously on the same channel, then communication throughput increases, but mutual interference between links increases
Solution Approach 1:
The patent implements dynamic link activation and deactivation based on terminal device capabilities and channel usage. The main control device activates or deactivates specific links in real-time, allowing the system to adapt to changing conditions. This dynamic control enables multiple links to operate on the same channel when interference is manageable, while preventing interference when terminals cannot handle multiple simultaneous links.
Solution Approach 2:
The system changes the operational state parameter of links (active/inactive) based on terminal device capabilities and channel conditions. By adjusting which links are active, the system optimizes throughput while controlling interference. The main control device manages link states dynamically, changing parameters to match terminal capabilities and channel usage patterns.
2Productivity
If multiple links are activated for a terminal device, then data transmission capacity increases, but device complexity increases
Solution Approach 1:
The patent merges link management functions into a single main control device that coordinates all links. Instead of each device independently managing its own links, the main control device consolidates the complexity of managing multiple links across the network, making the system easier to control while maintaining high data transmission capacity.
Solution Approach 2:
The main control device acts as an intermediary between terminal devices and the multi-link network infrastructure. It receives capability information from terminals, determines appropriate link configurations, and manages link activation/deactivation. This intermediary role simplifies the complexity by centralizing decision-making about link management.
3Productivity
If links are dynamically activated and deactivated, then communication efficiency improves, but control complexity increases
Solution Approach 1:
The terminal device provides self-service by reporting its capabilities to the main control device. The main control device uses this information to automatically determine which links should be activated or deactivated. This self-service approach reduces control complexity by enabling the system to make automated decisions based on terminal capabilities without requiring complex manual configuration.
Solution Approach 2:
The system implements feedback mechanisms where terminal devices report their capabilities and channel conditions to the main control device. Based on this feedback, the main control device adjusts link activation and deactivation decisions. This feedback loop enables efficient communication by continuously adapting to changing conditions while keeping control complexity manageable through automated responses.
