Ceramics Pin Grid Array Anti-Counterfeit Housing Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-counterfeiting technologies for physical manufactured products lack effective methods to ensure product authenticity and integrity, particularly at the joint of two housing bodies, which can be compromised during detachment or modification.
Innovation Solution
An anti-counterfeit system incorporating a ceramics-based pin grid array embedded in one housing body, connected with an RFID circuit that reports a confirmation signal upon interrogation, but self-terminates and deletes its code upon detachment from the pin grid array, ensuring authenticity and integrity of the original joint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anti-counterfeiting methods are used, then product identification is possible, but product integrity and joint authenticity cannot be verified
Solution Approach 1:
The patent combines multiple anti-counterfeiting functions into a single integrated encryption device that includes both an RFID circuit and a ceramics-based pin grid array embedded together. This merging allows the device to simultaneously verify product authenticity through RFID and joint integrity through the pin grid array configuration, resolving the contradiction by achieving enhanced reliability without proportionally increasing device complexity
Solution Approach 2:
The encryption device embeds the ceramics-based pin grid array within the housing body structure, nesting the cryptographic element inside the physical product. This nesting approach allows the authentication functionality to be integrated into the product itself rather than added as a separate external component, thereby improving reliability while minimizing the increase in device complexity
2Ease of repair
If the housing bodies are made detachable for servicing, then maintenance is enabled, but product integrity verification becomes compromised
Solution Approach 1:
The encryption device is configured to detect the detachment of housing bodies before servicing occurs and immediately terminates the confirmation signal capability. This preliminary action ensures that once the housing is opened for maintenance, the system proactively prevents any future authenticity verification, thereby maintaining joint integrity confirmation while still allowing authorized servicing to proceed
Solution Approach 2:
The encryption device's authentication capability is designed as a single-use, non-renewable resource. Once the housing bodies are detached and the pin grid array connection is broken, the confirmation signal function is permanently terminated and cannot be restored. This disposable nature of the authentication capability ensures that integrity verification is maintained for the product's entire service life without requiring complex reversible mechanisms
3Adaptability or versatility
If the encryption code remains accessible after detachment, then future servicing is possible, but product integrity is compromised
Solution Approach 1:
The system applies preliminary anti-action by pre-programming the encryption device to automatically delete or terminate the confirmation signal capability upon detecting housing detachment. This preemptive measure eliminates the possibility of code reuse after servicing, thereby neutralizing the counterfeiting risk that would otherwise exist if the encryption code remained accessible. The harmful factor of potential counterfeiting is prevented in advance rather than detected and corrected later
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively confirms product authenticity and integrity by preventing further signal reporting upon separation of the housing bodies, providing a secure and tamper-proof mechanism for verifying the originality of the product and its components.
Implementation Method 1
an RFID circuit. The RFID circuit is connected with the ceramics-based pin grid array. The RFID circuit is configured to report out a confirmation signal based on the code set by the connected ceramics-based pin grid array upon an interrogation trigger from an RFID reader

AI summary
An anti-counterfeit product of manufacture includes a housing defining a cavity. The housing is constructed of a first and second bodies forming an original joint at a parting line. Inner workings of the product are enclosed within the cavity. An encryption device includes an encryption-coded ceramics-based pin grid array embedded in the first body of the housing. An RFID circuit is connected with the ceramics-based pin grid array. The RFID circuit is configured to report out a confirmation signal based on the code set by the connected ceramics-based pin grid array upon an RFID reader interrogation trigger. The RFID circuit is programmed to prevent future reporting of the confirmation signal upon detachment of the ceramics-based pin grid array from the RFID circuit, such that the confirmation signal is configured to confirm both product authenticity and integrity of the original joint.
