RFID Tag Placement in Roofing Layers Without Surface Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for manufacturing roofing products with advanced identification, such as RFID tags, face challenges like inadequate manufacturing techniques, damage to tags during the process, and difficulty in applying tags to tacky surfaces, leading to defects and increased production costs.
Innovation Solution
A method involving the use of a tamp-blow applicator to blow RFID tags onto a roofing product's first layer using pressurized gas or air, avoiding contact with the tacky surface and ensuring reliable and cost-effective integration of RFID tags within the roofing product layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID tags are applied to roofing products using conventional contact-based methods, then the tags can be attached to the product, but the tags and product are damaged due to the tacky surface and manufacturing conditions
Solution Approach 1:
The patent introduces pressurized gas as an intermediary medium to transfer the RFID tag from the applicator to the roofing product surface. This gas-mediated transfer mechanism eliminates direct contact between the applicator and the tacky roofing surface, preventing contamination and damage while ensuring reliable tag attachment.
Solution Approach 2:
The patent replaces the conventional mechanical contact-based tag application system with a pneumatic system. Instead of using mechanical pressure or adhesive contact, the system uses controlled gas flow to propel and position the tag on the product surface, thereby avoiding mechanical damage and contamination.
2Ease of manufacture
If conventional contact-based tag application methods are used, then tags can be applied to roofing products, but the manufacturing process becomes complex and costly due to damage and defects
Solution Approach 1:
The patent employs pneumatic technology to simplify the tag application process. By using pressurized gas to deliver and place tags on the roofing product, the system eliminates complex mechanical positioning mechanisms, adhesive application systems, and damage prevention mechanisms required in conventional contact-based methods.
3Reliability
If contact-based methods are used to apply RFID tags, then tags can be attached, but the tacky roofing surface causes soiling and delamination of the product
Solution Approach 1:
Pressurized gas serves as a clean intermediary that transfers the tag without direct contact between the applicator and the roofing surface. This prevents the tacky surface material from sticking to the applicator and being transferred to the tag or surrounding areas, thereby preventing soiling and delamination.
Solution Approach 2:
By replacing mechanical contact with pneumatic tag delivery, the system eliminates the source of soiling and delamination problems. The gas flow carries the tag to the surface without the applicator touching the tacky material, preventing contamination and maintaining product integrity.
