RFID-Embedded Hoselines for Low-Consumption Inline Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for embedding RFID chips in hoses and pipelines are inefficient, as they require additional effort, risk loss or damage, and are not suitable for integration during production, leading to performance issues and high material consumption.
Innovation Solution
Embedding an RFID structure with a carrier and securely arranged chips parallel to the hose's longitudinal axis, where the carrier is made of yarn and twisted with antennas, eliminating the need for winding devices and reducing material usage, and protecting the chips with a protective enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID chips are mounted on the outside of the hose after production, then identification is possible, but additional effort is required and there is risk of loss or damage
Solution Approach 1:
The RFID chips are introduced into the hoseline blank during the production process itself, before the hose is completed. The chips are fed through the extrusion line and embedded in the elastomeric layers as the hose is being manufactured, eliminating the need for separate post-production mounting operations.
Solution Approach 2:
The RFID chips are nested within the multi-layer elastomeric structure of the hose. The chips are positioned between functional layers (such as between the inner tube and reinforcement layers), embedding them securely within the hose construction rather than mounting them on the exterior surface.
2Reliability
If RFID chips on carrier material are wound around a plastic tube or applied spirally, then identification is possible, but consumption of RFID threads is high and winding devices are required
Solution Approach 1:
The patent extracts the RFID chips from their traditional carrier material (such as strips or threads) and introduces them directly into the hose structure. The chips are fed individually or in groups through the production line and embedded directly into the elastomeric layers, eliminating the need for carrier material and reducing overall RFID component consumption.
Solution Approach 2:
The patent replaces the mechanical winding system with a feed-through system. Instead of using winding devices to wrap carrier material around the hose, RFID chips are fed linearly through the production line and positioned within the hose structure during extrusion, substituting a simpler feeding and embedding mechanism for complex winding equipment.
3Ease of manufacture
If RFID chips are introduced during hose production, then embedding is improved, but the form and format of traditional RFID chips cause delamination and product failure
Solution Approach 1:
The patent applies local quality by positioning RFID chips at specific locations within the hose structure where they will not interfere with critical functions. Chips are placed in zones between functional layers where their presence does not disrupt the structural integrity or performance of the hose, thereby maintaining both ease of embedding and product reliability.
Solution Approach 2:
The patent integrates RFID chips into the composite elastomeric structure of the hose. The chips become part of the multi-material construction, combining the elastomeric layers with the electronic components in a unified structure where the chips are surrounded and protected by the elastomeric material, preventing delamination and ensuring reliable product performance.

AI summary
A method for producing hoselines having at least the following working steps: a) providing a hoseline or pipeline blank (1, 2, 3) of at least one elastomeric and/or thermoplastic base material in a production device, while reinforcing elements may be embedded in the base material; and b) introducing an RFID structure (4, 4A, 4B, 4C) into the outer layer (3) of the hoseline or pipeline blank (1) in the axial direction parallel to the longitudinal axis of the hoseline or pipeline blank (1) and synchronously with the feed rate of the production device, the RFID structure having at least one carrier (4A) and the RFID structure (4, 4A, 4B, 4C) having RFID chips (4B) securely arranged on the carrier (4A) at predetermined spaced intervals.
