Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If remote radio heads are refurbished and upgraded through manual assessment, then repair decisions can be made, but the process consumes excessive resources and time
Solution Approach 1:
The patent applies preliminary action by implementing automated testing that assesses remote radio head conditions before repair decisions are made. The system pre-evaluates multiple parameters (signal quality, hardware functionality, software version) to determine whether refurbishment is viable, eliminating the need for time-consuming manual assessments and enabling faster repair decisions.
2Measurement precision
If remote radio heads are tested manually to determine refurbishment needs, then repair accuracy can be achieved, but resource consumption increases
Solution Approach 1:
The patent replaces manual mechanical testing with automated electronic testing systems. The automated tester connects to the remote radio head and electronically assesses signal quality, hardware functionality, and software versions, maintaining high measurement precision while eliminating the labor-intensive manual processes that consume excessive resources.
3Reliability
If entire remote radio head units are replaced instead of refurbished, then reliability is ensured, but costs escalate
Solution Approach 1:
The patent applies parameter changes by systematically evaluating multiple parameters (signal quality thresholds, hardware functionality, software version compatibility) to determine whether a remote radio head can be successfully refurbished. This structured approach identifies units suitable for refurbishment while ensuring that reliability standards are met, reducing the need for complete unit replacement.
4Manufacturing precision
If comprehensive testing of remote radio heads is implemented, then refurbishment quality improves, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a multi-functional automated testing device that performs multiple assessment functions (signal quality measurement, hardware diagnostics, software version checking) through a single integrated system. This universal tester connects to various remote radio head models and executes comprehensive evaluations, improving refurbishment quality while avoiding the complexity of multiple separate testing devices.
