Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical injection devices face challenges with traceability, as machine-readable identifiers like barcodes and RFID tags are susceptible to damage and tampering, and their placement often hinders effective scanning and tracking from manufacturing to disposal.
Innovation Solution
Integration of RFID tags within the tip cap assembly of medical devices, utilizing adhesive layers and meshed substrates to protect against damage and tampering, with configurations that enhance readability and provide tamper evidence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machine-readable identifiers like barcodes and RFID tags are placed on the surface of medical injection devices, then traceability is enabled, but the identifiers become susceptible to damage and tampering
Solution Approach 1:
The RFID tag is embedded within the tip cap assembly structure, specifically positioned within the rigid cap or rigid tip cap components. This nesting approach integrates the identifier into the device's structural elements, protecting it from external damage and tampering while maintaining traceability functionality throughout the device lifecycle.
Solution Approach 2:
The RFID tag is combined with the tip cap assembly components, where the tag becomes an integrated part of the rigid cap or rigid tip cap structure. This merging ensures the identifier moves with the device components and cannot be easily separated or tampered with, while adhesive layers provide additional bonding and protection.
2Object-affected harmful factors
If RFID tags are integrated within the tip cap assembly, then protection against damage and tampering is improved, but the complexity of device assembly increases
Solution Approach 1:
The RFID tag is pre-positioned and secured within the tip cap assembly components during manufacturing, before the final assembly with the syringe body. Adhesive layers are applied in advance to bond the tag to the rigid cap or rigid tip cap, ensuring the identifier is already protected when the complete device is assembled, thereby simplifying the final assembly process.
Solution Approach 2:
Adhesive layers serve as intermediary materials between the RFID tag and the tip cap assembly components. These adhesives facilitate the bonding process, securing the tag within the structure without requiring complex mechanical fastening systems, thus protecting the identifier while maintaining assembly simplicity.
3Measurement precision
If RFID tags are positioned on the distal end of the rigid tip cap, then machine readability is improved, but the tags become more exposed to potential damage
Solution Approach 1:
The RFID tag positioned on the distal end of the rigid tip cap is nested within the protective structure of the tip cap assembly, where the rigid cap or rigid tip cap components provide physical protection. This nesting enables the tag to maintain optimal positioning for machine scanning while being shielded from external damage and environmental factors.
Solution Approach 2:
The tip cap assembly utilizes composite construction with rigid cap and rigid tip cap components that provide structural protection. These composite materials offer both the mechanical strength needed for protection and the appropriate geometric features that enable reliable RFID scanning from the distal end position.
