Magnetic RFID Tag Bracket for Logistics Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID tag systems for tracking mobile objects, such as trucks and intermodal containers, are labor-intensive to install and remove, and require permanent attachment, limiting their versatility and efficiency in logistics and supply-chain management.
Innovation Solution
A bracket with a first arm for mounting to a support surface and a second arm for securing a temporary RFID tag, featuring an attachment mechanism like magnets for secure and accessible tag placement, designed to be easily installed, removed, and reused across multiple objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID tags are permanently secured to objects using screws, bolts, rivets, or welding, then the tag attachment is secure and reliable, but the installation and removal process becomes labor intensive and time consuming
Solution Approach 1:
The system is divided into three separate components: a bracket attached to the mobile object, an RFID tag, and a mounting surface. The bracket acts as an intermediary that remains permanently attached to the object while the tag can be easily mounted and dismounted from the bracket's surface, separating the permanent attachment function from the temporary tagging function.
Solution Approach 2:
The bracket serves as an intermediary component between the mobile object and the RFID tag. It provides a mounting surface that facilitates easy tag attachment and removal without requiring direct permanent attachment of the tag to the object, thus mediating between the need for secure attachment and easy repositioning.
2Reliability
If RFID tags are permanently attached to objects, then each object requires a dedicated tag, but this increases the number of tags needed and reduces versatility for multiple uses
Solution Approach 1:
The bracket provides a universal mounting interface that can accommodate multiple different RFID tags over time. Instead of permanently attaching a specific tag to a specific object, the bracket remains on the object while allowing various tags to be mounted and removed as needed, making the tagging system versatile and reusable.
Solution Approach 2:
The system allows RFID tags to be easily removed (discarded from their permanent attachment role) and reused on different objects or purposes. The bracket retains its position on the mobile object while the tag can be recovered and repositioned, enabling multiple uses of the same tag across different applications.
3Reliability
If RFID tags are permanently secured to objects, then the tag position is fixed and secure, but the tag becomes difficult to access for scanning and reading
Solution Approach 1:
The system transitions from a static permanent attachment to a dynamic configuration where the tag can be moved between different positions on the bracket's surface. The bracket provides stable positioning while allowing the tag to be dynamically repositioned or removed for optimal scanning access depending on the operational context.
