Tamper-Evident Identification Article With Release Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identification technologies, such as RFID tags, often require complex manufacturing processes and materials that are not easily adaptable for creating flexible, tamper-evident identification articles that can be easily attached and detached without damaging the adhesive layer.
Innovation Solution
A method and article comprising a band with an identification component sandwiched between two layers of strip material, where one layer has an adhesive coating and the other has a release section coated with a release agent, allowing for easy attachment and detachment while providing tamper-evident features through die cuts or perforations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a release section coated with release agent is provided on one layer, then the identification article can be easily attached and detached, but the adhesive layer may be damaged during detachment
Solution Approach 1:
The patent applies release agent coating only to specific localized areas (release sections) rather than the entire surface. This allows the article to be easily detached from these specific regions while preserving the adhesive integrity in other areas. The release agent creates a localized non-stick property that enables controlled detachment without damaging the overall adhesive layer.
2Reliability
If complex manufacturing processes are used for RFID tags, then identification functionality is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent divides the identification article into distinct functional segments: an identification component (such as RFID tag), a band structure with two layers, adhesive layers, and release sections. This segmentation allows each component to be manufactured separately using simpler processes and then assembled together, reducing overall manufacturing complexity while maintaining full identification functionality.
Solution Approach 2:
The patent combines the identification component with a flexible band structure that includes adhesive and release sections. By merging these functions into a single integrated article, the patent eliminates the need for separate manufacturing and assembly processes for multiple components, thereby reducing manufacturing complexity while achieving reliable identification functionality.
3Reliability
If die cuts or perforations are added for tamper-evident features, then tamper evidence is provided, but manufacturing complexity increases
Solution Approach 1:
The patent incorporates die cuts or perforations during the initial manufacturing process rather than adding them later. These features are pre-formed in the band or release section to create visible evidence of tampering when the article is opened or manipulated. By establishing this tamper-evident feature in advance, the patent avoids adding complex structural elements later while maintaining reliable tamper detection capability.
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 the creation of flexible, tamper-evident identification articles that can be easily manufactured and attached/detached without damaging the adhesive, enhancing security and usability by ensuring the integrity of the adhesive layer and providing clear evidence of tampering.
Implementation Method 1
a bottom side of a first layer is coated with an adhesive layer adapted to adhere to a top side of said second layer
Implementation Method 2
At least one end portion of the second layer is a release section provided with a coating of a release agent which provides a release effect against the adhesive
