Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual means are used for performing electrical tilting on multi-band antennas, then the operation can be performed, but the accuracy is reduced and adjustment errors occur
Solution Approach 1:
The system automatically performs electrical tilting operations through automated mapping tables that associate remote electrical tilt devices with cells and frequency bands. The management apparatus autonomously determines the correct RET device for each cell without requiring manual intervention, thereby eliminating human error while maintaining operational simplicity.
Solution Approach 2:
The patent introduces a management apparatus as an intermediary between the operator and the remote electrical tilt devices. This intermediary automatically queries mapping relationships, determines the correct RET device for each cell, and executes the tilting operations, thereby eliminating the need for manual operation while ensuring high accuracy.
2Area of stationary object
If multi-band antennas are deployed to save antenna panel space, then space utilization is improved, but the complexity of managing remote electrical tilt devices increases
Solution Approach 1:
The management apparatus serves as an intermediary that automatically handles the complexity of managing multiple RET devices for multi-band antennas. It queries mapping relationships between RET devices, cells, and frequency bands, then automatically determines the correct device to operate, thereby simplifying the management process despite the increased number of devices.
Solution Approach 2:
The patent segments the management process into distinct functional modules: querying mapping relationships, determining target RET devices, and executing tilting operations. This segmentation allows the system to handle complex multi-band antenna management through a structured, step-by-step approach that reduces overall system complexity.
3Reliability
If automated mapping tables are implemented for managing RET devices, then operational accuracy is improved, but the device complexity increases
Solution Approach 1:
The management apparatus acts as an intermediary that implements automated mapping tables to reliably determine the correct RET device for each cell. By automating the query and determination process, the system achieves high operational reliability while keeping the complexity contained within the management layer rather than propagating it throughout the entire system.
