Forgery-preventing thread/yarn
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for authenticating genuine products are hindered by the increasing sophistication of forgery and imitation products, which are difficult to distinguish without specialized ultraviolet or infrared irradiation tools, and can be replicated by counterfeiters, leading to increased costs and prices for genuine products.
Innovation Solution
A forgery-preventing thread/yarn formed from a slit film with printed letters or images, which can be easily identified using camera-equipped electronic devices, featuring a protective layer and potential fluorescence under UV/IR light, allowing consumers to verify product authenticity at a low cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ultraviolet/infrared-irradiating means are used for authentication, then product authenticity can be determined, but consumers cannot easily verify authenticity without specialized equipment
Solution Approach 1:
The patent creates a visible copy or representation of the authentication feature by printing letters and images directly on the thread. Instead of requiring consumers to view the thread under UV/IR light to see authentication markings, the same authentication information is copied onto the thread surface in visible form, allowing verification with the naked eye or simple magnification.
Solution Approach 2:
The patent introduces printed letters and images on the thread as an intermediary between the UV/IR reactive properties and the consumer. These printed markings serve as a visible mediator that conveys authentication information without requiring the consumer to possess UV/IR irradiating equipment.
2Reliability
If forgery-preventing labels using UV/IR reactive threads are used, then genuine products can be protected, but counterfeiters can also manufacture similar labels making discrimination difficult
Solution Approach 1:
The patent applies local quality by incorporating printed letters and images at specific locations and orientations on the thread. The printing pattern includes specific characteristics such as line width, spacing, and arrangement that are difficult to replicate. This localized detailed structure creates a quality distinction that goes beyond the general UV/IR reactive property, making counterfeiting more difficult.
3Reliability
If sophisticated forgery prevention measures are implemented, then genuine products can be protected from counterfeiting, but the cost of prevention increases leading to higher product prices
Solution Approach 1:
The patent changes the parameters of the thread by incorporating printed markings with specific visual characteristics. Instead of relying solely on the material property of UV/IR reactivity, the patent adds printed letters and images with defined line widths, spacing, and patterns. This parameter enhancement provides additional authentication layers that are cost-effective to implement through standard printing processes.
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
Enables consumers to determine genuine products from counterfeits using common electronic devices, reducing the market and production of imitation products by providing a cost-effective means of authentication.
Implementation Method 1
a forgery-preventing label formed using a thread/yarn which is capable of developing colors as it is irradiated with ultraviolet ray or infrared ray

AI summary
According to the present invention, there is provided, at low cost, a thread/yarn for making it possible to easily determine whether a product is a genuine product or a forgery/imitation product, thereby suppressing the manufacture and marketing of forgery/imitation products. This forgery-preventing thread/yarn is formed by making use of a film comprising abase sheet and letters or images printed on the base sheet, the film being slit to have a width of 0.15 mm˜0.75 mm. A thread, yarn or a flat thread representing a genuine product can be cheaply manufactured since it can be obtained by simply slitting a film to a width of 0.15 mm˜0.75 mm. Further, it is possible to easily determine whether a product is a genuine product or a forgery/imitation.
