Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems with multiple intermediate and terminal management devices, using a single frequency band limits communication efficiency, necessitating time division communication which is inefficient.
Innovation Solution
Implementing a communication system that uses multiple frequency bands, where each group of management and terminal devices communicates on assigned non-overlapping frequency bands, allowing parallel communication and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple management devices use a single frequency band for wireless communication, then device complexity is reduced, but communication efficiency deteriorates due to time division requirements
Solution Approach 1:
The patent divides the communication system into multiple groups, where each group is assigned a dedicated frequency band. This segmentation allows different groups to communicate simultaneously on different frequencies, eliminating the need for time division and improving overall communication efficiency without requiring complex coordination mechanisms.
Solution Approach 2:
The patent transitions from single-frequency communication to multi-frequency communication by introducing a frequency dimension. Each group operates on its own assigned frequency band, allowing parallel communication across multiple groups simultaneously, thereby resolving the efficiency limitation of single-frequency time-division communication.
2Device complexity
If time division communication is used to manage multiple devices on one frequency band, then frequency band usage is simplified, but communication processing capability is reduced
Solution Approach 1:
The system segments the communication workload by assigning dedicated frequency bands to different groups. This allows simultaneous communication processing across multiple groups without interference, effectively increasing the overall communication processing capability while maintaining simple frequency management within each group.
Solution Approach 2:
By adding the frequency dimension to the communication architecture, the system enables parallel processing of communications across multiple groups. Each group operates independently on its assigned frequency band, eliminating the sequential time-division constraint and boosting communication processing capability.
3Device complexity
If multiple groups share a single frequency band, then system configuration is simplified, but signal interference increases
Solution Approach 1:
The patent segments the frequency spectrum into dedicated bands for different groups. This segmentation physically separates the communication signals in the frequency domain, eliminating signal interference between groups while maintaining a relatively simple system configuration where each group uses its assigned band.
Solution Approach 2:
The system moves from single-frequency operation to multi-frequency operation, utilizing the frequency dimension to separate signals. This dimensional separation allows multiple groups to communicate simultaneously without signal interference, as each group operates on its own dedicated frequency band.
