Particle Track Detection for Authenticating Metal Products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional proportional analysis methods fail to accurately detect the authenticity of elemental substance products, such as noble metals, due to counterfeit products mimicking the density of authentic products by surface coatings, leading to inaccurate detection results.
Innovation Solution
A detection method and system that reconstructs particle tracks before and after penetrating the object under detection, utilizing muons or electrons to analyze scattering and blocking forces, enabling accurate detection based on internal structure features rather than density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If proportional analysis method is used to detect authenticity based on density, then detection process is simple, but detection accuracy deteriorates because counterfeit products can mimic the density of authentic products through surface coatings
Solution Approach 1:
The patent replaces the conventional proportional analysis method (mechanical/physical measurement of density) with particle track analysis using muons or electrons. By detecting how particles scatter and are blocked by the object's internal structure, the system achieves accurate material identification without relying on density measurements, thus resolving the contradiction between simple detection process and accurate detection results
Solution Approach 2:
The patent changes the detection parameter from macroscopic density to microscopic particle interaction characteristics (scattering angle, track length, energy loss). This parameter transformation enables differentiation between authentic and counterfeit products at the atomic level, where counterfeit surface coatings cannot replicate the internal atomic structure that determines particle scattering patterns
2Reliability
If surface coating with elemental substance is applied to counterfeit products, then counterfeit products can mimic authentic product density, but internal structure remains different
Solution Approach 1:
The patent introduces high-energy particles (muons or electrons) as intermediaries to probe the internal structure of the object. These particles penetrate through surface coatings and interact with the atomic nuclei in the bulk material, providing information about the internal structure that cannot be obtained by external measurements alone. This intermediary approach allows differentiation between authentic and counterfeit products despite similar surface appearances
Solution Approach 2:
The patent replaces conventional external measurement methods (density measurement, surface inspection) with particle physics-based internal structure analysis. By using particle scattering and energy loss measurements, the system directly probes the atomic composition and structure, making it impossible for surface coatings to deceive the detection system
