1Object-affected harmful factors
If electromagnetic shielding material is used to inhibit electromagnetic radiation interference, then the EMI protection is improved, but the cost increases and the production process becomes more complex
Solution Approach 1:
The patent changes the operating parameters (clock frequency, spread spectrum settings) of the generating chips to move their harmonic frequencies away from the communication frequency bands, thereby eliminating EMI without requiring physical shielding materials or mold changes
Solution Approach 2:
The patent replaces the mechanical/physical approach of electromagnetic shielding with an electronic/software-based approach of dynamic parameter adjustment and harmonic analysis, substituting physical barriers with algorithmic interference management
2Object-affected harmful factors
If electromagnetic shielding material is used to inhibit electromagnetic radiation interference, then the EMI protection is improved, but the cost increases
Solution Approach 1:
The patent changes the operating parameters (clock frequency, spread spectrum settings) of the generating chips to move their harmonic frequencies away from the communication frequency bands, thereby eliminating EMI without requiring expensive shielding materials
Solution Approach 2:
The patent uses software-based parameter adjustment that can be implemented through firmware updates or configuration changes, replacing expensive physical shielding materials with low-cost digital control mechanisms
3Object-affected harmful factors
If clock frequency is adjusted to avoid harmonic interference, then the EMI is reduced, but the processing speed may be affected
Solution Approach 1:
The patent implements dynamic parameter adjustment where clock frequencies and spread spectrum settings are modified in real-time based on the operating conditions and identified interference patterns, allowing the system to optimize both EMI reduction and processing performance
Solution Approach 2:
The patent changes operating parameters (clock frequency, spread spectrum settings) to eliminate harmonics while maintaining processing efficiency by selecting alternative frequency configurations that preserve data throughput
