Radiation Risk Assessment via Signal Spectrum Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation tests in EMC assessments are typically qualitative, leading to costly redesigns and resource wastage, as they are conducted late in the production stage and do not provide a quantitative assessment of radiation risk.
Innovation Solution
A method and device for quantitative radiation risk assessment, which involves determining a risk signal from a product design model, assessing its periodicity, calculating radiation intensity using spectrum amplitude, current intensity, and distance, and comparing it to a standard intensity to generate a risk assessment result.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radiation test is performed in the later stage of product production, then the product design is finalized, but manpower and material resources are wasted on redesign and remedial measures
Solution Approach 1:
The patent performs radiation risk assessment during the product design stage by calculating radiation intensity based on product design models, signal characteristics, and antenna parameters. This preliminary assessment identifies potential radiation issues before production is completed, allowing designers to modify the design proactively rather than performing costly remedial measures after production, thus resolving the contradiction between assessment accuracy and time/resource waste
2Measurement precision
If qualitative assessment of radiation risk is performed, then the assessment process is simple, but quantitative assessment capability is lacking
Solution Approach 1:
The patent replaces complex physical radiation measurement systems with a computational model that calculates radiation intensity using mathematical formulas based on product design models, signal spectrum amplitudes, and antenna current distributions. This substitution achieves quantitative assessment through software calculation rather than complex physical measurement equipment, resolving the contradiction between measurement precision and device complexity
