Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for detecting counterfeit electronic components are limited by human error, small sample sizes, lengthy inspection times, and the need for manual research, and often rely on single inspection techniques, which are not effective in verifying conformance to pre-specified requirements.
Innovation Solution
An automated model-based inspection system that conducts a multi-tier inspection process using different types of identification tests and historical analysis, including fuzzy logic, to verify the conformance of electronic components, allowing for flexible algorithm selection and reducing human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If human inspectors compare components to a known reference component, then inspection can be performed with simple equipment, but inspection time becomes lengthy and human error occurs
Solution Approach 1:
The patent replaces the mechanical human inspection process with an automated optical inspection system that uses image capture devices, processing units, and algorithmic analysis. The system captures images of electronic components, processes them through multiple tiers of analysis including fuzzy logic algorithms, and automatically determines conformance without human intervention, thereby eliminating human error while maintaining high inspection speed.
2Device complexity
If a single inspection technique is used, then the inspection process is simple, but detection capability is limited
Solution Approach 1:
The patent divides the inspection process into multiple distinct tiers, each employing different identification tests and analysis methods. Tier 1 performs initial screening, Tier 2 conducts more rigorous analysis, and Tier 3 performs final verification. This segmentation allows the system to apply appropriate levels of complexity to different stages, improving overall detection accuracy while managing process complexity through structured organization.
Solution Approach 2:
The inspection system combines multiple different identification tests and analysis methods into a composite inspection approach. Each tier uses different techniques (visual inspection, dimensional measurement, marker detection, fuzzy logic analysis) that complement each other, creating a robust multi-method system that overcomes the limitations of any single inspection technique.
3Adaptability or versatility
If manual research process is used to determine testing requirements, then testing can be customized, but inspection time increases
Solution Approach 1:
The system performs preliminary classification of electronic components in Tier 1 to identify the type of component and its specific inspection requirements. Based on this preliminary action, the system automatically selects and configures the appropriate tests and analysis methods for Tiers 2 and 3, eliminating the need for manual research while maintaining customized testing approaches for different component types.
Solution Approach 2:
The inspection system dynamically adjusts the testing protocol based on the component being inspected. The processing unit automatically modifies which tests are applied, the stringency of analysis, and the algorithms used, based on real-time identification of component type, manufacturer, and specifications. This dynamic adaptation provides testing flexibility without requiring manual intervention or increasing inspection time.
Data Source
AI summary
A method includes obtaining data associated with an electronic component. The method also includes conducting a multi-tier inspection process to verify a conformance of the electronic component. Each of the tiers includes a different type of identification test, and at least one of the tiers is configured to provide fuzzy outputs. The method further includes analyzing the data associated with the electronic component using one or more first tests associated with a first of the tiers to determine whether the electronic component conforms to a pre-specified requirement. In addition, the method includes generating an output based on the analysis and determining whether additional testing is required using one or more next-level tests associated with another of the tiers.
