Pivotable RFID Label for Metal Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
RFID labels face performance issues due to electromagnetic wave absorption and reflection by materials like metals and water, leading to reduced communication distances and the need for human intervention to orient objects or manually enter data, which increases costs and errors.
Innovation Solution
A foldable label design with a pivotable holding part allows the RFID tag to protrude from the object, enabling manual adjustment for improved data reception and avoiding interference from object materials, and can be applied using a device with supporting elements for easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the RFID label is pasted flat against the object, then the label is securely attached to the object, but electromagnetic waves are absorbed or reflected by the object materials (metals, water), reducing communication distance and data reception quality
Solution Approach 1:
The holding part is designed to fold out from the pasting part, transitioning the RFID tag from a flat two-dimensional configuration to a three-dimensional protruding structure. This dimensional change positions the tag in a different spatial plane, allowing it to extend beyond the object surface and avoid direct contact with electromagnetic wave-absorbing materials like metals and water, thereby improving communication distance and data reception quality
2Device complexity
If the RFID tag is calibrated only to resonant frequency detection, then the tag structure is simple, but human intervention is required for orienting objects or manually entering data, increasing costs and errors
Solution Approach 1:
The holding part is designed as a foldable structure that can be manually adjusted to different orientations. This dynamic capability allows the RFID tag to be positioned optimally for data reception without requiring complex automated positioning systems, maintaining simple tag structure while improving ease of operation and reducing human intervention for data processing
