Adhesive Tamper-Evident Labels With Frangible Layer Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive labels can be easily removed and replaced on counterfeit products, providing no clear indication of tampering, and vehicle registration plates are often copied or stolen, leading to fraudulent activities and legal complications for vehicle owners.
Innovation Solution
An adhesive tamper evident label with a frangible layer having lines of weakness that break upon removal, revealing an inner layer to provide a clear visual indication of tampering, and a support layer that fragments upon unauthorized detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive labels are made removable for application purposes, then ease of operation is improved, but reliability is worsened because the labels can be removed and transferred to counterfeit products without clear indication of tampering
Solution Approach 1:
The label is divided into multiple layers including a frangible support layer with lines of weakness, an inner layer, and an outer layer. When the label is removed, the frangible layer segments into multiple pieces while the inner layer remains attached to the substrate, providing clear visual evidence of tampering and preventing complete label transfer to counterfeit products.
Solution Approach 2:
The frangible support layer is pre-configured with lines of weakness that will break upon removal attempts. This preliminary structural arrangement ensures that any removal action automatically triggers the tamper-evident mechanism, making it impossible to remove the label without leaving visible evidence on the substrate.
2Ease of operation
If vehicle registration plates are made adhesive for easy attachment, then ease of operation is improved, but reliability is worsened because plates can be stolen and copied without obvious indication
Solution Approach 1:
The registration plate consists of multiple layers with a frangible support layer containing lines of weakness. When someone attempts to remove the plate, this layer breaks into segments while leaving the inner layer on the vehicle, providing immediate visual evidence of theft or tampering and preventing complete plate removal for copying purposes.
Solution Approach 2:
The frangible support layer acts as an intermediary between the adhesive outer layer and the substrate. It mediates the removal process by breaking under stress, thereby preventing direct transfer of the entire plate assembly and providing a visible barrier that indicates tampering has occurred.
3Reliability
If anti tamper devices are added to labels, then reliability is improved, but device complexity is worsened
Solution Approach 1:
The tamper-evident functionality is achieved through segmentation of the label into distinct layers with specific functions. The frangible support layer with lines of weakness provides the tamper-evident mechanism, while the inner and outer layers provide structural integrity and visual display. This segmentation allows each layer to be optimized for its specific function without requiring complex integrated mechanisms.

AI summary
The present invention provides an adhesive tamper evident vehicle registration label or an adhesive tamper evident label support. The adhesive tamper evident vehicle registration label comprises a frangible layer of a label comprising an upper surface and an opposed lower surface, in which the frangible layer comprises a plurality of layer portions located adjacent to each other and separable from each other by at least one line of weakness extending between the upper and lower surfaces thereof. The adhesive tamper evident label support comprises a frangible support layer for receiving a label, the frangible support layer comprising an upper surface for receiving a label thereon, and an opposed lower surface, in which the frangible support layer comprises a plurality of support layer portions located adjacent to each other and separable from each other by at least one opening and/or line of weakness extending between the upper and lower surfaces of the support layer. The adhesive tamper evident vehicle registration label or the adhesive tamper evident label support further comprise an adhesive layer located in use on the lower surface of the frangible layer or frangible support layer and configured to adhere the frangible layer or frangible support layer to a contact surface. The frangible layer of the adhesive tamper evident vehicle registration label or frangible support layer of the adhesive tamper evident label support is moveable between a first untampered position in which the layer portions or support layer portions provide a continuous surface extending across the upper surface thereof, and a second tampered position in which at least a pair of adjacent layer portions or support layer portions are separated from each other along the corresponding at least one opening and/or line of weakness.
