Rubber RFID Tag Antenna Anchoring for Deformation Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection between the substrate and the antenna in RFID tags used in rubber products is unreliable, leading to separation and inability to read information from the RFID tag.
Innovation Solution
The RFID tag design includes a substrate with a connecting part, such as a hole or groove, where the antenna is securely connected through the connecting part, providing a stable and reliable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the antenna is superimposed and welded on the substrate surface, then the installation is simple, but the connection reliability is poor and separation occurs easily under deformation
Solution Approach 1:
The antenna is inserted into a connecting hole formed in the substrate, creating a nested structure where the antenna is housed within the substrate thickness. This nesting approach provides mechanical anchoring that prevents separation while maintaining manufacturing simplicity through a single-piece substrate structure.
Solution Approach 2:
The connection transitions from a two-dimensional surface welding approach to a three-dimensional through-hole insertion approach. The antenna passes through the substrate thickness dimension, creating anchoring effects at both the top and bottom surfaces, which significantly improves connection reliability under deformation conditions.
2Reliability
If the antenna is connected through a connecting hole or groove in the substrate, then the connection reliability is improved, but the manufacturing complexity increases
Solution Approach 1:
The substrate is designed with local variations: most of the substrate maintains uniform thickness, but specific localized regions contain connecting holes or grooves. This local quality approach provides the necessary mechanical anchoring for reliable antenna connection while keeping the overall substrate structure simple and manufacturable.
Solution Approach 2:
The substrate is segmented functionally into different zones: the main substrate body for signal transmission and localized connecting holes/grooves for mechanical anchoring. This segmentation allows each zone to optimize its function while maintaining overall structural simplicity.
