Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face interference issues due to multiplied system frequencies, which can degrade wireless communication performance by interfering with radio frequencies and GPS communications.
Innovation Solution
An electronic device is designed with a processor and memory that manage system frequencies based on interference relationships with specific radio frequency bands, allowing for adjustments to prevent interference through frequency changes when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system frequency is multiplied to provide various functions, then the functionality and integration of the electronic device is improved, but interference with radio frequencies and GPS communications occurs
Solution Approach 1:
The patent implements dynamic frequency adjustment where the system frequency is changed based on the operational state of wireless communication circuits. The processor monitors whether wireless communication is being performed and adjusts the system frequency accordingly - using a first frequency when wireless communication is active and a second frequency when it is not, thereby preventing interference while maintaining functionality.
Solution Approach 2:
The patent changes the system frequency parameter based on operational conditions. By switching between different frequency values (first frequency and second frequency) depending on whether wireless communication is being performed, the system resolves the contradiction between maintaining high functionality and preventing interference with radio frequencies.
2Reliability
If the system frequency is changed to avoid interference, then wireless communication performance is improved, but system complexity increases
Solution Approach 1:
The patent employs a feedback mechanism where the processor continuously monitors the operational state of wireless communication circuits and adjusts the system frequency accordingly. This closed-loop control ensures that frequency changes are made only when necessary (when wireless communication is being performed), improving performance while avoiding unnecessary complexity from constant frequency adjustments.
Solution Approach 2:
The system automatically adjusts its own frequency based on its operational state without requiring external intervention. The processor itself manages the frequency switching based on whether wireless communication circuits are actively transmitting or receiving, making the system self-regulating and reducing the need for additional complex control mechanisms.
