Syringe RFID Tag Layout for Protected Traceability

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing medical containers, such as pre-fillable or prefilled syringes, lack efficient individual traceability solutions that are not prone to damage, do not interfere with visual inspection, and maintain manufacturing integrity, while avoiding contamination risks.

Innovation Solution

Integrate an RFID on-metal (ROM) tag located partly inside the barrel channel of the syringe, with an antenna extending along the needle, ensuring protection from external damage and maintaining visual inspection clarity, and utilizing the needle as an antenna transmitter for enhanced reading/writing distance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If printed unique identifier codes are used on the external side of the receptacle, then individual traceability is enabled, but the codes may be removed or damaged during handling and use

Engineering Contradiction:

Improvetraceability reliabilityVSAvoidcode durability

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The RFID tag is nested inside the barrel channel of the syringe, with the antenna extending along the needle. This nested configuration protects the identifier from external damage while maintaining traceability functionality throughout the product lifecycle.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent replaces mechanical printed codes with an RFID electromagnetic identification system. This substitution eliminates the physical vulnerabilities of printed codes while enabling reliable remote identification without contact.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If printed unique identifier codes are placed on the external side of the receptacle, then traceability is achieved, but the codes obstruct the user visual inspection process

Engineering Contradiction:

Improvetraceability capabilityVSAvoidvisual inspection difficulty

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The RFID tag is positioned inside the barrel channel, nested within the syringe structure. This placement enables traceability identification while keeping the external surface clear for visual inspection by healthcare professionals.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Reliability

If inkjet printing is used to print identifier codes on the receptacle, then traceability is provided, but there is a risk of contamination of the receptacle

Engineering Contradiction:

Improveidentification capabilityVSAvoidcontamination risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces inkjet printing with RFID electromagnetic tagging. This substitution eliminates ink-related contamination risks while providing equivalent or superior identification capabilities through non-contact electromagnetic fields.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If a RFID tag is integrated into the medical container, then protected traceability is achieved, but the tag may add thickness to the container

Engineering Contradiction:

Improvetraceability protectionVSAvoidcontainer thickness

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

The RFID antenna is configured to extend along the longitudinal axis of the needle rather than adding radial thickness. This dimensional reorientation allows the tag to be integrated within the existing profile of the syringe components.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The RFID tag components are nested within the barrel channel and along the needle structure, utilizing existing spatial volumes without increasing the overall external dimensions of the medical container.

Inventive Principle:

Principle #7Nested doll (Nesting)
