Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional EMC measurement device is used, then measurement accuracy is maintained, but installation space and facility maintenance cost increase
Solution Approach 1:
The patent creates a simplified copy or model of the traditional EMC measurement system using a relationship equation that correlates measurements from a compact device to equivalent full-scale measurements. This allows accurate EMC assessment without requiring the complete original measurement infrastructure, thereby reducing installation space while maintaining measurement precision through mathematical transformation of the data.
Solution Approach 2:
The patent introduces a relationship equation as an intermediary that bridges the gap between simplified measurements and full EMC compliance requirements. This mathematical mediator transforms data from a compact measurement setup into equivalent results that would otherwise require large-scale facilities, thus maintaining accuracy while reducing physical space requirements.
2Reliability
If a traditional EMC measurement device is used, then comprehensive EMC assessment is achieved, but facility maintenance cost increases
Solution Approach 1:
The patent replaces expensive, maintenance-intensive traditional EMC measurement facilities with a more economical measurement approach based on relationship equations and simplified hardware. This substitution reduces facility maintenance costs while maintaining reliable EMC compliance assessment through validated mathematical models that ensure measurement reliability.
Solution Approach 2:
The patent creates a cost-effective copy of the traditional measurement capability through relationship equations that replicate the functionality of expensive facilities. This virtual or mathematical copy maintains reliability for EMC compliance determination while dramatically reducing the need for costly physical infrastructure and its associated maintenance expenses.
3Measurement precision
If a traditional EMC measurement device is used, then accurate EMC data is obtained, but measurement time increases
Solution Approach 1:
The patent performs preliminary work by establishing relationship equations that capture the correlation between simplified measurements and full EMC parameters in advance. These pre-developed mathematical models allow for rapid measurement execution without sacrificing accuracy, as the complex transformation logic has already been worked out and validated, enabling quick application to actual measurement data.
Solution Approach 2:
The patent replaces the mechanical or physical complexity of traditional EMC measurement systems with mathematical relationships and computational methods. This substitution eliminates time-consuming physical setup and measurement procedures while maintaining measurement precision through validated equations that can be applied rapidly to obtain accurate EMC data.
