IC Tag Sticker Single-Stroke Line for Wine Bottle Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IC tag stickers on wine bottles do not effectively prevent the malicious replacement of genuine wine with counterfeit by detecting tools inserted through the cork, as the antenna is not destroyed when a needle is inserted from the upper surface.
Innovation Solution
A sticker with an IC tag that includes a single-stroke line portion within its disconnection detection circuit, which is designed to disconnect when a tool is inserted from the upper surface, allowing the IC chip to detect and prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is installed to stretch across both the cork and container body, then the antenna can detect opening of the container, but the antenna is not destroyed when a tool is inserted from the upper surface of the cork
Solution Approach 1:
The detection circuit is divided into multiple independent conductive paths: the antenna loop and the single-stroke line portion. Each path serves a specific detection function - the antenna detects container opening while the single-stroke line detects tool insertion, allowing independent operation of each detection mechanism
Solution Approach 2:
Different regions of the sticker are assigned different functions: the antenna loop is positioned to detect container opening, while the single-stroke line portion is specifically placed on the upper surface of the cork to detect tool insertion attempts. Each region has optimized properties for its specific detection purpose
2Reliability
If a brittle processing for cutting off a slit is carried out for impedance matching adjustment, then the antenna can be destroyed when the cover is opened, but the antenna would not be destroyed when a tool is inserted from the upper surface of the cover
Solution Approach 1:
The detection functionality is segmented into two separate conductive structures: the antenna loop with slit for opening detection, and the single-stroke line portion for tool insertion detection. This segmentation allows each structure to be optimized for its specific detection purpose without interfering with the other
Solution Approach 2:
Instead of relying on the antenna loop to detect tool insertion (which fails because the tool enters from above), the patent introduces a separate single-stroke line portion that is specifically designed to be interrupted by tool insertion from the upper surface, inverting the detection approach
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 solution reliably prevents malicious replacement by ensuring the disconnection of the single-stroke line portion when a tool is inserted, effectively securing the contents of the container.
Implementation Method 1
An RFID tag is composed of an RFIC chip for processing wireless signals, and an antenna for transmitting and receiving the wireless signals. Specified information is transmitted and received between the antenna of the RFID tag and the antenna of the reader as high frequency signals through a magnetic field or electric wave.

AI summary
A sticker with IC tag comprises: an antenna portion; and an IC chip coupled to the antenna portion and having a function of communicating through the antenna portion. The sticker with IC tag is installed on a covered container. The sticker with IC tag comprises a single-stroke line portion, which is coupled to the IC chip and adhered to an upper surface of a cover portion of the covered container. The IC chip detects disconnection of the single-stroke line portion.
