Electronic Device Frequency Adjustment for Wireless Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices automatically decrease processor speed to reduce interference with wireless signals, but this is unnecessary when interference is minimal, leading to operational constraints.
Innovation Solution
An electronic device with a storage unit and processor that uses a determining, calculating, analyzing, and control module system to adjust working frequency only when interference with wireless signals exceeds a predetermined threshold, selecting an alternative antenna and calculating time intervals to minimize influence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the working frequency is increased to improve processing speed, then productivity is improved, but harmful electromagnetic interference with wireless signals increases
Solution Approach 1:
The patent dynamically adjusts the working frequency parameter based on detected interference levels. When interference exceeds a threshold, the system changes the frequency parameter to a lower value, thereby reducing electromagnetic interference while maintaining high processing speed when conditions permit
Solution Approach 2:
The system implements a feedback mechanism by detecting the level of electromagnetic interference generated by the processor and automatically adjusting the working frequency in response. This closed-loop control allows the system to maintain optimal performance while minimizing harmful interference effects
2Object-generated harmful factors
If the processor speed is automatically decreased to reduce interference, then harmful electromagnetic interference is reduced, but device operation becomes unnecessarily constrained
Solution Approach 1:
The patent applies partial action by decreasing processor speed only to the extent necessary to reduce interference below the threshold, rather than always maintaining maximum speed reduction. This allows the system to maintain high performance when interference levels are acceptable while only partially constraining operation when needed

AI summary
A method for adjusting a working frequency of an electronic device includes the following. First, determining a current working frequency of the electronic device, a minimum average frequency among the average frequencies of different channels, and a frequency range of one channel used for transmitting/receiving wireless signals. Second, calculating an interference frequency generated by the electronic device, and selecting another antenna to transmit/receive wireless signals when the interference frequency falls within the frequency range of the determined channel. Third, calculating a first time interval between transmitting and receiving wireless signals before switching to the other antenna, and a second time interval between transmitting and receiving wireless signals after switching to the other antenna. Fourth, determining a difference between the first and second time intervals. Fifth, adjusting the current working frequency to decrease the influence on the transmission/receipt of wireless signals when the calculated difference is greater than a predetermined threshold.
