Electronic Hard Tag Adhesion Structure for Tamper Destruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic hard tags can be easily removed from products without leaving visible damage, compromising their functionality and security.
Innovation Solution
The electronic hard tag incorporates a radio frequency identification circuit enclosed in a housing with multiple adhesion layers, including a first circuit adhesion layer attaching the circuit to the housing and a product adhesion layer securing it to the product, designed to destroy the circuit upon attempted removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional hard tag with a closed housing is used to protect the electronics, then the tag is protected from mechanical damage, but the tag can be easily removed from the product without leaving visible damage
Solution Approach 1:
The tag is segmented into two functional layers: a housing containing the electronics and a separate destruction layer. This segmentation allows the housing to provide mechanical protection while the destruction layer independently provides anti-removal security through its sacrificial structure.
Solution Approach 2:
The destruction layer is designed to be damaged or removed along with the tag, converting the potential harm of tag removal into a beneficial security feature. When the tag is removed, the destruction layer is compromised, providing visible evidence of tampering and preventing reuse.
2Object-affected harmful factors
If the hard tag is made robust with a closed housing, then the electronics are protected from harsh conditions, but the tag can be levered off the product without destruction
Solution Approach 1:
The tag structure is segmented into a protective housing and a separate destruction layer that is sacrificially designed. This allows the housing to be robust and protective while the destruction layer provides the necessary resistance to unauthorized removal through its sacrificial nature.
Solution Approach 2:
The destruction layer is pre-configured with sacrificial elements that are designed to be damaged before the tag can be fully removed. This preliminary sacrificial damage prevents easy removal by requiring the destruction of the destruction layer first.
3Ease of manufacture
If a simple adhesive tag is used, then the tag is easy to apply, but the tag can be removed and reused without damage
Solution Approach 1:
The tag is segmented into a reusable housing and a sacrificial destruction layer. This segmentation maintains the ease of application of adhesive tags while adding anti-counterfeit protection through the destruction layer that prevents reuse after removal.
Solution Approach 2:
The destruction layer is designed as a disposable, sacrificial element that is intentionally damaged during removal. This cheap, short-living component provides anti-counterfeit protection while the main housing can be reused or replaced.
