Multi-Layer Peel and Reseal Label With Segmented RFID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional labels with a single functional layer cannot accommodate multiple RFID devices due to interference, and they lack the capability to display different text information in various languages, making it difficult to create a stack of labels with individual identities without dismantling.
Innovation Solution
A multi-part peel and reseal label assembly with a base layer and stacked informational layers, where the base layer includes a far field RFID device and each informational layer has a near field RFID device, allowing the layers to repeatedly peel apart and reseal, and accommodating fixed or variable printed information in multiple languages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple far field RFID devices are placed in labels, then label identification capability is improved, but device interference and de-tuning occurs
Solution Approach 1:
The invention divides the RFID system into two distinct types: a far field RFID device in the base layer for overall label identification, and multiple near field RFID devices in informational layers for component-level tracking. This segmentation allows different RFID technologies to coexist without interference, as they operate on different principles and frequency ranges.
Solution Approach 2:
The invention adds a vertical dimension to RFID device placement by stacking near field devices on separate informational layers above the base layer. This multi-layer spatial arrangement allows multiple RFID devices to function simultaneously without the horizontal interference that would occur if they were placed side-by-side on the same layer.
2Ease of manufacture
If a single functional layer is used in labels, then manufacturing simplicity is maintained, but information display capability is limited
Solution Approach 1:
The label is divided into a base layer and multiple detachable informational layers, each serving specific functions. The base layer contains the far field RFID device and adhesive, while informational layers contain near field RFID devices and printed information. This segmentation allows each layer to be optimized independently while maintaining overall manufacturing efficiency.
Solution Approach 2:
The informational layers are nested on top of the base layer, creating a multi-layer structure where each layer can be peeled off and resealed. This nested configuration allows multiple information displays and RFID devices to be integrated within a compact label structure without significantly increasing manufacturing complexity.
3Stability of the object's composition
If informational layers are permanently bound, then structural stability is improved, but peeling and resealing capability is lost
Solution Approach 1:
The adhesive binding is applied selectively only at the edges of the informational layers, rather than across the entire surface. This localized adhesive application provides sufficient structural stability to keep layers bound during normal handling, while leaving the central areas free to be peeled apart and resealed repeatedly.
Solution Approach 2:
The label structure transitions from a completely fixed configuration to a dynamic system where informational layers can be temporarily separated and reattached. The partial adhesive binding creates a semi-permanent connection that allows controlled movement and reconfiguration, enabling users to peel and reseal layers as needed while maintaining overall structural integrity.
