Engineering Contradiction Analysis
1Speed
If high-speed data communication is implemented, then data transmission speed is improved, but electromagnetic radiation interference increases
Solution Approach 1:
The patent applies resonance theory to convert the harmful EMR energy into a controlled resonant oscillation that can be dissipated. The EMR dissipating device is configured to resonate at the same frequency as the EMR source, absorbing the harmful electromagnetic energy and converting it into a controllable resonance that can be safely dissipated through resistive elements.
Solution Approach 2:
The EMR dissipating device serves as an intermediary element between the EMR source and the load component. It is electrically coupled to both the EMR source and the load component, acting as a mediator that absorbs and dissipates EMR before it can interfere with the load component, thereby protecting the system while maintaining high-speed data transmission.
2Object-affected harmful factors
If EMR dissipating device is added to filter EMR, then electromagnetic interference is reduced, but device complexity increases
Solution Approach 1:
The EMR dissipating device is designed to perform multiple functions: it filters EMR from the output signal, maintains signal integrity, and can be integrated into existing circuit architectures. The device includes a resonant circuit configuration that can be adapted to different operating frequencies and circuit topologies, making it a versatile solution for EMR mitigation across various high-speed communication applications.
3Object-generated harmful factors
If EMR dissipating device is electrically coupled to EMR source, then EMR dissipation is improved, but signal loss may increase
