Tamper-Evident Electronic Anti-Counterfeiting Label
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-counterfeiting labels in high-end product packaging can be easily tampered with or copied, allowing authentic products to be replaced with fake ones, as they can be torn off or have visible verification codes that can be replicated.
Innovation Solution
An anti-counterfeiting assembly featuring an electronic screen with a battery-powered anti-counterfeiting label that displays identification information, integrated with a circuit board and a switch, which becomes unusable upon damage, ensuring the authenticity of the product by rendering the label irreusable if tampered with.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional anti-counterfeiting label is used, then the product packaging is simple and easy to manufacture, but the label can be easily torn off or copied, compromising security
Solution Approach 1:
The anti-counterfeiting label is divided into multiple independent layers: a base layer, a transparent adhesive layer containing conductive particles, and a circuit board. These layers are electrically connected in series, creating a segmented structure where each layer contributes to the overall anti-counterfeiting function while maintaining manufacturability
Solution Approach 2:
A transparent adhesive layer containing conductive particles serves as an intermediary between the base layer and the circuit board. This intermediate layer provides both adhesive function and electrical conductivity, enabling tamper detection without requiring complex additional components
2Ease of operation
If verification codes are displayed in plain sight on the label, then verification is simple for consumers, but the codes can be easily copied by counterfeiters
Solution Approach 1:
The label utilizes optical properties where the transparent adhesive layer with conductive particles creates visual effects that change under different lighting conditions or viewing angles. This allows verification through visual inspection while making copying difficult, as counterfeiters cannot replicate the dynamic optical characteristics
Solution Approach 2:
The patent replaces traditional mechanical verification methods (reading printed codes) with an electrical verification system. The conductive particles and circuit board create an electrical circuit that can be tested with simple tools, providing verification while preventing copying through electrical rather than visual means
3Ease of manufacture
If the label uses only adhesive fixation, then application is simple, but the label can be easily removed and reused
Solution Approach 1:
The label is designed with conductive particles embedded in the adhesive layer before application. This preliminary configuration of conductive elements ensures that any attempt to remove or relocate the label will disrupt the electrical circuit, providing built-in tamper detection without complicating the application process
Solution Approach 2:
The patent merges multiple functions into the adhesive layer: adhesion, electrical conductivity, and tamper detection. By combining these functions in a single layer rather than using separate components, the label maintains simple application while achieving high tamper resistance
