Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Security labels that indicate first opening often leave residues when detached, require high mechanical effort for removal, and can result in uncontrollable product fragments, making them difficult to manage, especially in adverse conditions.
Innovation Solution
A security label with a carrier and adhesive layer, featuring layers with different tension sets that allow for stretchability and irreversible deformation upon detachment, enabling residue-free removal and clear indication of manipulation, while also incorporating a predetermined breaking point for easy opening and reduced scrap generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security labels use high adhesion strength to prevent detachment and indicate first opening, then security function is improved, but residue-free removal becomes difficult and requires high mechanical effort
Solution Approach 1:
The carrier is divided into multiple layers (first layer and second layer) with different tension sets. The first layer has higher tension set than the second layer, allowing the layers to separate during detachment. This segmentation enables the label to be removed without leaving residue while maintaining security function, as the layers can be peeled apart cleanly rather than requiring forceful removal that damages the surface.
Solution Approach 2:
The patent changes the physical parameter of tension set across different layers of the carrier. By designing the first layer with a higher tension set than the second layer, the material properties are optimized to allow easy separation between layers while maintaining strong adhesion to the substrate. This parameter variation enables residue-free removal without compromising security.
2Reliability
If security labels are made with strong adhesion to ensure security, then security function is improved, but residue is left on the surface after detachment
Solution Approach 1:
The carrier is segmented into multiple layers with different tension sets. During detachment, the layers separate from each other while the adhesive remains on the substrate. This segmentation allows the label to be removed cleanly without leaving residue on the surface, while the adhesive layer maintains its security function during the bonded state.
Solution Approach 2:
The multi-layer carrier structure acts as an intermediary between the adhesive and the label elements. The layers with different tension sets mediate the detachment process, allowing the adhesive to remain on the substrate while the label layers peel away cleanly, preventing residue formation on the surface.
3Reliability
If security labels use high tear resistance to prevent unauthorized opening, then security function is improved, but the label must be cut up or removed before opening the sealed object
Solution Approach 1:
The carrier is segmented into layers with different tension sets that can separate during detachment. This segmentation allows the label to be removed in a controlled manner without requiring cutting, as the layers peel apart naturally due to their different mechanical properties, simplifying the opening process while maintaining security.
4Ease of operation
If security labels are designed for easy stripping and residue-free removal, then ease of operation is improved, but product fragments can slip out of control and get into air ducts or joints
Solution Approach 1:
The carrier is segmented into controlled layers that separate in a predictable manner during detachment. The first layer with higher tension set separates from the second layer with lower tension set in a controlled sequence, preventing uncontrolled fragmentation. This controlled segmentation allows easy removal while minimizing the risk of product fragments becoming airborne and entering air ducts or joints.
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 label can be easily and completely removed without residue, indicating first opening clearly, while its design enhances manageability and prevents reuse, ensuring secure and efficient handling.
Implementation Method 1
The carrier of the security label also has at least two layers A, B. These two layers A, B differ from one another in any case with regard to their tension set... Due to the difference in the permanent set in tension, a permanent three-dimensional deformation occurs when the security label is stretched
Implementation Method 2
Due to the difference in the permanent set in tension, a permanent three-dimensional deformation occurs when the security label is stretched, as occurs during an attempt to detach it from the substrate to be bonded, and subsequent relaxation
Implementation Method 3
A security label according to the invention has a carrier and below the carrier an adhesive layer for fixing the label to an object to be secured

AI summary
The invention relates to a security label (1) for use as initial opening verification having a carrier (4), wherein said carrier has at least one first layer A and one second layer B, and having an adhesive layer (3) for application on an object (2) to be secured, wherein said adhesive layer is disposed below said carrier, wherein a marker is provided, which irreversibly indicates a removal attempt from the object, and wherein said security label is implemented so it can be stretched. It is proposed that the two layers A, B have tension sets which differ from one another, the security label is three-dimensionally deformed after stretching and subsequent relaxation, and the deformation implements the marker.
