Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional EMI suppression methods are used, then some level of EMI protection is achieved, but the suppression is inadequate to reach predetermined EMI levels
Solution Approach 1:
The EMI suppression system is divided into multiple functional segments: energy conversion subsystem, communication subsystem, and EMI suppression subsystem. Each segment handles specific aspects of energy management and EMI protection, allowing targeted suppression at different stages of energy transmission and conversion.
Solution Approach 2:
The patent introduces intermediary components such as shielding structures, filtering elements, and isolation barriers between energy sources, conversion devices, and loads. These intermediaries actively intercept and suppress EMI energy propagation, preventing direct coupling between interfering sources and sensitive equipment.
2Object-affected harmful factors
If energy conversion subsystem is added to suppress EMI, then EMI suppression capability is improved, but system complexity increases
Solution Approach 1:
The energy conversion subsystem is designed to perform multiple functions simultaneously: primary energy conversion (e.g., thermal to electrical), EMI suppression through controlled energy dissipation, and signal isolation. This multi-functionality reduces the need for separate dedicated EMI suppression components, thereby limiting complexity increase.
Solution Approach 2:
The patent merges EMI suppression functionality directly into the energy conversion subsystem by integrating shielding materials, filtering circuits, and energy dissipation mechanisms within the same structural framework. This consolidation eliminates the need for separate EMI suppression apparatus, reducing overall system complexity.
3Object-affected harmful factors
If EMI suppression measures are implemented, then EMI energy propagation is reduced, but energy conversion efficiency may be affected
Solution Approach 1:
The system converts potentially harmful EMI energy into useful work by directing intercepted electromagnetic energy through energy conversion subsystems that transform it into electrical energy or other useful forms. This approach eliminates waste energy while maintaining suppression effectiveness, actually improving overall energy efficiency.
Solution Approach 2:
The patent employs parameter optimization in the design of energy conversion devices, adjusting operational parameters such as operating frequency, impedance matching, and material properties to minimize energy losses during conversion. This ensures that EMI suppression measures do not degrade the primary energy conversion efficiency.
