Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electromagnetic noise analysis is performed on large-scale devices with multiple electronic components from different manufacturers, then comprehensive noise analysis coverage is improved, but analysis complexity and difficulty increase due to ambiguous noise model definitions and combination methods
Solution Approach 1:
The patent segments the large-scale device into multiple electronic component units, each with its own standardized noise model. This allows the complex system to be analyzed by combining results from individual component analyses rather than attempting to analyze the entire system at once, thereby improving noise analysis coverage while managing complexity through modular processing
Solution Approach 2:
The patent establishes universal noise model definitions and combination methods that can be applied across different electronic components from various manufacturers. This standardized approach enables comprehensive noise analysis of multi-vendor systems without requiring component-specific analysis procedures, improving both coverage and managing complexity through standardization
2Ease of operation
If standardized noise model definitions and combination methods are established for multi-manufacturer devices, then ease of operation is improved, but device complexity increases due to the need for standardized interfaces and protocols
Solution Approach 1:
The patent creates standardized noise model templates and combination method frameworks that can be copied and applied to different electronic components. These standardized models serve as reusable templates that simplify the analysis process while the complexity of standardization is confined to the template creation phase rather than each individual analysis
Solution Approach 2:
The patent uses parameterized noise models that can be configured for different components by changing specific parameters rather than requiring entirely different models. This allows standardized interfaces and protocols to handle complexity internally while presenting a simple, uniform interface to users performing the noise analysis
