Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for embedding RFID chips in hoses and pipes are inefficient, prone to damage, and affect the mechanical properties of the products, as they require additional components and processes that can lead to delamination and increased effort.
Innovation Solution
A linear structure made of electrically conductive material is applied to the outer surface of hose or pipe blanks, with RFID chips placed at predetermined intervals, forming an electrical connection and being fixed during the manufacturing process, allowing for flexible adaptation and integration without significantly impacting mechanical properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID chips are mounted on carrier material labels or strips and attached to the outside of the hose, then identification and monitoring are enabled, but additional effort is required and there is risk of loss or damage
Solution Approach 1:
The RFID chip carrier material is integrated directly into the hose wall structure during the extrusion process, merging the identification function with the hose body. This eliminates separate attachment steps and reduces the risk of loss or damage while maintaining reliable identification.
Solution Approach 2:
The RFID carrier material is prepared and positioned within the hose blank before the final vulcanization process. This preliminary placement ensures the RFID chips are securely embedded in the correct positions before the hose is completed, reducing subsequent manufacturing effort and improving reliability.
2Reliability
If RFID chips on carrier material strips are wound or spirally applied around the plastic tube, then identification is achieved, but a corresponding winding device is required and RFID thread consumption is high
Solution Approach 1:
The hose structure is segmented into functional layers, with the RFID carrier material forming a distinct layer within the hose wall. This segmentation allows the RFID components to be integrated during extrusion without requiring separate winding devices, simplifying the manufacturing equipment while maintaining identification capability.
3Manufacturing precision
If RFID chips are embedded using transfer foil process, then marking is achieved, but additional components and work steps are required
Solution Approach 1:
The RFID carrier material is combined with the hose extrusion process itself, merging the hose manufacturing and RFID embedding operations into a single integrated process. This eliminates the need for separate transfer foil applications and reduces overall process complexity while maintaining precise embedding.
