Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electromagnetic feature values are measured to determine mechanical properties, then non-destructive measurement is achieved, but measurement precision deteriorates due to varying relationships between electromagnetic features and mechanical properties
Solution Approach 1:
The patent applies parameter changes by measuring multiple electromagnetic feature values (magnetic permeability, electrical conductivity, density, elastic modulus, Poisson's ratio) instead of relying on a single parameter. This multi-parameter approach compensates for the varying relationship between electromagnetic features and mechanical properties, enabling accurate mechanical property determination through comprehensive parameter analysis while maintaining non-destructive measurement capability
Solution Approach 2:
The patent implements universality by creating a comprehensive measurement system that can determine multiple mechanical properties (density, elastic modulus, Poisson's ratio, tensile strength, yield strength, hardness) through a single set of electromagnetic feature value measurements. This multi-functional approach allows the system to adapt to different material types and measurement requirements, improving both reliability and precision across diverse applications
2Measurement precision
If multiple physical quantities are measured to improve measurement accuracy, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent applies merging by integrating multiple electromagnetic measurement functions into a single comprehensive measurement system. Instead of using separate devices for measuring magnetic permeability, electrical conductivity, density, elastic modulus, and Poisson's ratio, the system combines these measurement capabilities into one unified apparatus, thereby improving measurement precision while minimizing the increase in device complexity
Solution Approach 2:
The patent replaces traditional mechanical measurement methods with electromagnetic measurement techniques. By using electromagnetic fields to measure physical quantities that were traditionally measured mechanically, the system achieves high measurement precision without requiring complex mechanical test equipment, thereby reducing overall device complexity while maintaining accuracy
