PSA Sheet Authenticity Check Using Carbon-14 Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying counterfeit products and components, particularly those with internal bonding members like PSA sheets, are cumbersome, require expertise, and lack precision, making it difficult to distinguish between genuine and counterfeit items quickly and reliably.
Innovation Solution
A method involving the determination of the percentage of radioactive carbon-14 (14C) in constituents of a product or component using ASTM D6866, allowing for quick and precise authenticity judgments by comparing the 14C percentage of the object of interest to that of an authentic item, with a ±5% error margin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elemental analysis such as IR and NMR is used to identify counterfeits, then identification reliability is improved, but the cost and time required increase significantly
Solution Approach 1:
The patent changes the measurement parameter from complex spectral analysis (IR, NMR) to simple radioactive carbon-14 content measurement. This parameter change enables rapid identification of counterfeits while maintaining reliability, as the 14C content directly reflects the biomass origin of materials and can be measured quickly using standard radiocarbon dating techniques
2Measurement precision
If precision of analysis is pursued to ensure reliability of counterfeit identification, then identification accuracy is improved, but the cost required increases
Solution Approach 1:
The patent employs a cost-effective measurement approach by using radiocarbon dating technology that is relatively inexpensive compared to IR or NMR spectroscopy. The method uses standard 14C measurement techniques that can be performed with moderate equipment investment, making precise counterfeit identification economically viable for routine quality control
3Loss of information
If conventional analysis methods are used for counterfeit identification, then comprehensive material characterization is achieved, but expertise and analytical skills are required
Solution Approach 1:
The patent extracts the essential identification feature (radioactive carbon-14 content) from the complex material and measures only this specific parameter. This extraction approach simplifies the identification process to a single, straightforward measurement that does not require expert interpretation of complex spectra, while still providing reliable counterfeit detection based on the biomass origin of materials
