Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power adjustment is not implemented, then device complexity is low, but power offset affects communication performance
Solution Approach 1:
A calculating model is pre-stored in the modem that establishes the relationship between temperature, frequency, and power offset. During operation, the modem detects real-time temperature and frequency, then uses the pre-stored model to calculate and compensate for power offset, eliminating the need for complex real-time adjustment mechanisms while maintaining communication performance
Solution Approach 2:
The modem performs self-diagnosis and self-adjustment by detecting its own temperature and frequency, calculating the power offset using the pre-stored model, and automatically compensating for the offset. This self-service approach maintains reliability without requiring external control systems, thus avoiding increased device complexity
2Reliability
If real-time power adjustment is implemented, then power offset is compensated, but manufacturing complexity increases
Solution Approach 1:
The calculating model relating temperature, frequency, and power offset is pre-stored in the modem during manufacturing. This preliminary preparation allows the modem to perform real-time power adjustment using simple detection and calculation operations, avoiding the need for complex manufacturing processes while ensuring power stability
Solution Approach 2:
The patent transforms the complex power adjustment problem into a parameter-based calculation by establishing relationships between temperature, frequency, and power offset. The pre-stored model uses these parameters to determine the appropriate power adjustment, simplifying the manufacturing process while achieving reliable power compensation

AI summary
A modem includes a temperature detecting module, a frequency detecting module, and a power offset calculating module. The temperature detecting module detects a real-time-work temperature of the modem. The frequency detecting module obtains a real-time-work frequency of the modem. The power offset calculating module calculates a power offset by inputting the real-time-work temperature and the real-time-work frequency into a pre-stored calculating model and adjusts a power of the modem according to the calculated power offset. A method of adjusting power of the modem is also provided.
