Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the amplifying gain of network-controlled repeaters is not properly controlled, then the signal transmission distance can be extended, but interference increases and signal sensitivity decreases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the amplifying gain of network-controlled repeaters based on channel conditions, traffic load, and interference levels. The base station configures different gain values for different repeaters and time periods, optimizing the balance between transmission distance and interference control
Solution Approach 2:
The patent implements feedback mechanisms where the base station receives reports from repeaters about their operating conditions and signal quality, then adjusts the amplifying gain configuration accordingly. This closed-loop control enables the system to adapt to changing conditions and maintain optimal performance
2Area of stationary object
If the amplifying gain is increased to improve coverage, then the network coverage area expands, but signal accuracy and sensitivity are reduced
Solution Approach 1:
The patent applies local quality by configuring different amplifying gain values for different network-controlled repeaters based on their specific locations, channel conditions, and local interference environments. This localized optimization ensures that each repeater operates at the appropriate gain level for its specific context, maintaining signal accuracy while expanding coverage
3Device complexity
If manual configuration of amplifying gain is used, then device complexity is reduced, but adaptability to changing network conditions deteriorates
Solution Approach 1:
The patent implements self-service by enabling network-controlled repeaters to automatically adjust their amplifying gain based on pre-configured parameters and real-time conditions. The repeaters can autonomously respond to changing network conditions without requiring manual reconfiguration, while the base station provides initial configuration and oversight
