Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual parameter setting and verification is used between spectrum analyzer and base station control center, then communication capability is maintained, but testing time increases and convenience deteriorates
Solution Approach 1:
A communication module is introduced as an intermediary between the spectrum analyzer and base station control center, enabling automatic parameter transmission and control. The communication module transmits parameter information to the base station control center, which then automatically configures the base station, eliminating manual back-and-forth communication and significantly reducing testing time while improving convenience.
2Productivity
If direct wireless communication is implemented between spectrum analyzer and base station control center, then testing efficiency improves, but system complexity increases
Solution Approach 1:
The spectrum analyzer is equipped with a communication module that provides multi-functional capability: it can transmit parameter information to the base station control center, receive control instructions, and coordinate testing operations. This universal communication interface enables direct wireless communication without requiring separate dedicated systems, thereby improving testing efficiency while minimizing the increase in system complexity.
3Measurement precision
If automated parameter transmission is implemented, then measurement accuracy improves, but communication requirements increase
Solution Approach 1:
The system implements a feedback mechanism where the spectrum analyzer transmits parameter information to the base station control center, which then automatically configures the base station and provides confirmation. This closed-loop feedback ensures that parameters are accurately transmitted and correctly applied, improving measurement accuracy while using a relatively simple communication structure that does not require complex communication protocols.
