Stand-Up RFID Label Structure for Conductive Surface Tagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID labels face challenges in positioning the antenna structure away from conductive surfaces to ensure undisturbed data communication, as they often adhere directly to conductive objects, interfering with signal transmission.
Innovation Solution
A label with a stand-up mechanism featuring a base part and a stand-up part connected by a fold line, equipped with a pulling element that allows the stand-up part to be angled and secured at various positions relative to the base part, enabling the antenna to be positioned away from the substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the label adheres directly to the substrate, then the adhesive strength is maximized, but the antenna structure cannot be positioned away from the conductive surface
Solution Approach 1:
The label is divided into a base part and a stand-up part that can be folded relative to each other. The base part adheres to the substrate while the stand-up part positions the antenna away from the conductive surface, resolving the contradiction between maintaining adhesive strength and achieving antenna positioning distance.
2Reliability
If the stand-up part is folded to position the antenna away from the surface, then data communication is improved, but the label structure becomes more complex
Solution Approach 1:
The stand-up part is designed with a fold line allowing it to be dynamically positioned at different angles relative to the base part. This dynamic configuration enables the antenna to be positioned away from the conductive surface for improved data communication while maintaining a relatively simple overall label structure that can be adapted to different application scenarios.
3Reliability
If the stand-up foot is folded out to maintain the stand-up position, then the antenna remains positioned away from the surface, but the pulling element requires additional adhesive application
Solution Approach 1:
The pulling element is pre-equipped with adhesive on its second section before the label assembly process. This preliminary preparation allows the pulling element to be easily attached to the stand-up foot during assembly, maintaining the stand-up position stability while simplifying the overall manufacturing process by eliminating the need for separate adhesive application steps.
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 stand-up mechanism allows the antenna to be securely positioned at a distance from conductive surfaces, ensuring reliable data communication and providing mechanical flexibility for application on flat or curved surfaces while maintaining a large print area.
Implementation Method 1
a base part (100) which has an adhesive coating (110) on its underside for adhering the label (1) to a substrate
Implementation Method 2
The pull element (220) is configured in such a way that the stand-up foot (210) is pulled out of a plane of the stand-up part (200) when the stand-up part (200) is lifted

AI summary
A label with a stand-up mechanism includes a base part which has an adhesive coating on its underside for adhering the label to a substrate, and a stand-up part which is connected in one piece to the base part and is configured in such a way that the stand-up part can be set up at an angle greater than 0° to the base part by folding along a stand-up line. The stand-up part has a stand-up foot for setting up the stand-up part at the angle to the base part.
