Integrated RFID Tag with Loop Fixing Part for Low-Cost Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID tags are complex and expensive, making them unsuitable for low-cost products packed together, as they require separate parts and assembly, which increases costs and complexity, and are not easily attachable to products like bottles or cans without interfering with their functionality.
Innovation Solution
A novel RFID tag design using a single piece of sheet-like or film-like material for the fixing means, where the transponder is integrated either in the body or fixing part, allowing for simple and cost-effective manufacturing and attachment without separate joints, enabling easy attachment to products like bottles and cans without affecting their functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an RFID tag uses a body structure with multiple separate parts (collar, hinges, locking mechanism) to attach to objects like gas bottles, then the tag's usability and signal readability are improved, but the device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent merges the collar, hinges, and locking mechanism into a single integrated body structure. The body is formed as one piece with the collar and locking features built-in, eliminating the need for separate parts and complex assembly while maintaining the functionality of secure attachment and signal readability.
Solution Approach 2:
The body structure serves multiple functions simultaneously: it provides the mounting surface for the transponder, forms the collar that attaches to the object, incorporates the locking mechanism, and maintains the geometric configuration for RF signal readability. This multi-functionality reduces the number of separate components needed.
2Ease of manufacture
If an RFID tag uses a label type attachment method, then the manufacturing cost is reduced, but the tag cannot be easily attached to suitable reading positions on products like bottles or cans
Solution Approach 1:
The body is formed from a flexible sheet-like or film-like material that can be easily conform ed to the surface of products like bottles or cans. This material can be attached by simple wrapping or adhesion methods, combining low manufacturing cost with easy attachment to curved surfaces and various product geometries.
3Volume of moving object
If the transponder is placed close to the product surface, then the tag size is reduced, but liquid or metal proximity degrades the RF signal readability
Solution Approach 1:
The body is designed with a specific geometric configuration that positions the transponder at an optimized distance from the product surface. By controlling the thickness and shape of the body in the dimension perpendicular to the product surface, the design maintains compact size while ensuring the transponder remains far enough from interfering substances like liquid or metal.
