Removable RFID Tag with Magnetic Mount and Rotatable Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID tags used for tracking mobile objects are labor-intensive to install, remove, and replace, and require a separate tag for each object, making them inefficient for logistics and inventory management.
Innovation Solution
A removable RFID tag with a magnetic attachment mechanism and rotatable handles, designed for temporary attachment to metal surfaces, allowing easy installation and removal without specialized tools, and capable of withstanding harsh environments and multiple uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID tags are permanently secured to objects using screws, bolts, rivets, or welding, then the tags remain securely attached to the objects, but the installation and removal processes become labor-intensive and time-consuming
Solution Approach 1:
The attachment mechanism is divided into separate components: a mounting bracket that attaches to the object and a tag assembly that attaches to the bracket. This segmentation allows the tag to be easily removed and reattached without affecting the mounting bracket, significantly reducing installation and removal labor while maintaining secure attachment during use.
Solution Approach 2:
The patent replaces permanent mechanical fastening methods (screws, bolts, rivets, welding) with a magnetic attachment system. The magnet in the mounting bracket attracts the ferromagnetic material in the tag assembly, providing secure attachment that is easily released by simply separating the components, eliminating the need for tools and complex installation procedures.
2Reliability
If a separate RFID tag is provided for every object to be tagged, then each object has its own dedicated identification, but the system becomes complex and requires multiple tags to be managed
Solution Approach 1:
The tag assembly is designed as a universal component that can be attached to any object with a mounting bracket. The same tag assembly can be repeatedly attached to different objects (trailers, containers, equipment) and serves as their identification device, eliminating the need for separate dedicated tags for each object while maintaining accurate identification through the RFID reader system.
3Adaptability or versatility
If RFID tags are designed for temporary attachment and removal, then the tags can be reused on multiple objects, but the attachment security and reading stability may be compromised
Solution Approach 1:
The magnetic attachment system provides sufficient holding force to maintain the tag assembly securely on the object during normal operations, including vibration and movement. This magnetic force is strong enough to ensure stable RFID reading while still allowing easy removal when needed, thus maintaining both reading stability and reuse capability.
Solution Approach 2:
The mounting bracket includes a curved or contoured surface designed to conform to the shape of the object being tagged. This curvature ensures consistent contact and positioning of the tag assembly against the object surface, maintaining optimal reading conditions for the RFID system even when the object shape varies, thereby ensuring reading stability across different applications.

Function Achieved in This Case
The solution enables efficient and labor-saving real-time tracking of mobile objects, reducing labor costs and improving supply-chain management by allowing multiple uses of the same tag across different objects, while maintaining reading stability and durability across varying conditions.
Implementation Method 1
The attachment mechanism may comprise magnets, which are used to attach the RFID tag to a metal support surface.
