Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data is communicated over a single frequency band, then the system structure is simple, but the network experiences excessive load during high data traffic
Solution Approach 1:
The patent introduces a second frequency band as an additional dimension for data communication. When the first frequency band experiences high utilization, the system switches to or shares the second frequency band, effectively adding a dimensional resource to handle load and improve network efficiency without fundamentally complicating the system architecture.
Solution Approach 2:
The system dynamically changes the frequency band parameter based on utilization criteria. When the first frequency band's utilization exceeds a threshold, the system transitions to using the second frequency band for data communication, thereby adapting the operational parameters to maintain network efficiency under varying load conditions.
2Productivity
If multiple frequency bands are used for communication, then network load is balanced effectively, but the system complexity increases
Solution Approach 1:
The system implements dynamic frequency band selection based on real-time utilization monitoring. The access node and relay node adaptively switch between the first and second frequency bands according to load conditions, making the system flexible and efficient while maintaining a relatively simple static structure that only becomes complex during operation when needed.
Solution Approach 2:
The system performs self-monitoring of frequency band utilization and automatically makes switching decisions without external intervention. The access node monitors the utilization of the first frequency band and autonomously determines when to switch to the second frequency band, reducing the need for complex external control mechanisms.
3Reliability
If frequency band switching is implemented, then service quality is maintained during high traffic, but the control complexity increases
Solution Approach 1:
The system implements a feedback mechanism where the access node continuously monitors the utilization of the first frequency band and compares it against predefined thresholds. Based on this feedback, the system automatically triggers frequency band switching to maintain service quality, creating a simple closed-loop control system that ensures reliability without excessive complexity.
Solution Approach 2:
The system pre-configures multiple frequency bands and establishes utilization thresholds in advance. When monitoring indicates that the first frequency band's utilization meets the switching criteria, the system has already prepared the second frequency band for immediate use, allowing smooth transitions that maintain service quality without requiring complex real-time decision-making or preparation.
