Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual measurement and adjustment methods are used for signal power normalization, then system complexity is reduced, but commissioning time and error rate increase
Solution Approach 1:
The system performs self-configuration by automatically measuring signal power at multiple points and adjusting path gains without manual intervention. The controller autonomously normalizes signals by comparing measurements from different remote antenna units and calculating required gain adjustments, enabling the system to configure itself during commissioning.
Solution Approach 2:
The system pre-measures signal power levels at multiple measurement points before final system deployment. By conducting these measurements and calculations in advance during the commissioning phase, the system establishes optimal path gains beforehand, eliminating the need for time-consuming manual adjustments during operational commissioning.
2Device complexity
If manual measurement and adjustment methods are used for signal power normalization, then device complexity is reduced, but error rate increases
Solution Approach 1:
The system implements feedback by continuously measuring signal power at multiple points using power measurement devices and comparing these measurements against target levels. The controller uses this feedback information to automatically adjust path gains, ensuring accurate signal normalization and reducing errors associated with manual adjustments.
Solution Approach 2:
The system replaces manual mechanical adjustment procedures with automated electronic control. The controller electronically adjusts path gains based on algorithmic processing of measurement data, eliminating human error in manual measurement and adjustment while improving precision and reliability of signal normalization.
3Loss of time
If automated signal normalization is implemented, then commissioning time is reduced, but device complexity increases
Solution Approach 1:
The system divides the commissioning process into discrete automated segments: signal injection at the base station, power measurement at multiple remote points, data collection by the controller, and individual path gain adjustment. This segmentation allows complex automated normalization to be broken down into manageable functional blocks that can be implemented and maintained more easily.
Solution Approach 2:
The controller serves as an intermediary between the base station and remote antenna units, automatically managing the complex coordination required for signal normalization. It receives measurement data from multiple points, processes the information, and sends adjustment commands to appropriate components, simplifying the overall system architecture while enabling automated operation.
4Measurement precision
If multiple power measurement devices are deployed throughout the signal path, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The power measurement devices are designed to perform multiple functions: measuring signal power for normalization purposes, identifying interference sources, and providing diagnostic information. This multi-functionality justifies the deployment of multiple measurement devices throughout the system, as each device serves several purposes rather than a single specialized function.
Solution Approach 2:
The system combines multiple measurement functions into a unified automated commissioning framework. Rather than using separate dedicated devices for each measurement purpose, the power measurement devices are integrated into the overall signal normalization and diagnostic system, with the controller coordinating their use for multiple objectives simultaneously.
