Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical injection devices face challenges in individual traceability due to removable or damage-prone printed identifier codes and complex manufacturing processes for integrated RFID tags, which affect visual inspection and data transmission.
Innovation Solution
A cover for medical injection devices incorporating an RFID tag positioned between two casings, with a wide width and length, ensuring protection and high data transmission without visual impact, and minimal manufacturing disruption.
Engineering Contradictions & Design Principles
Engineering 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
Solution Approach 1:
The patent introduces an RFID tag as an intermediary between the receptacle and the tracking system. Instead of printing codes directly on the receptacle surface, the RFID tag serves as a mediator that stores identification data and can be read remotely, eliminating direct contact and reducing damage risk while maintaining traceability functionality
2Reliability
If printed unique identifier codes are used on the external side of the receptacle, then individual traceability is enabled, but they impact the user visual inspection process
Solution Approach 1:
The RFID tag acts as an intermediary that separates the identification function from the visual inspection function. The tag stores traceability data internally and communicates it electronically, while keeping the receptacle's external surface visually clear for user inspection of the medical product
3Reliability
If inkjet printing is used to print identifier codes on the external side of the receptacle, then individual traceability is enabled, but there is a risk of contamination of the receptacle
Solution Approach 1:
The RFID tag serves as an intermediary carrier for identification data, eliminating the need for inkjet printing on the receptacle surface. The tag can be attached separately or integrated into the closure system, keeping the receptacle surface free from ink contamination while maintaining traceability
Solution Approach 2:
The patent replaces the mechanical/chemical inkjet printing system with an electronic RFID system. Instead of using ink to create visible codes, the system uses electromagnetic fields to store and retrieve identification data, eliminating contamination risks associated with ink application
4Ease of manufacture
If a small RFID tag is used in the shield assembly, then the cover manufacturing process is not affected, but the data transmission level to the RFID reader is significantly reduced
Solution Approach 1:
The patent positions the RFID tag in the annular space between the outer and inner casings of the cover, utilizing the radial dimension rather than constraining it to a flat surface. This three-dimensional placement allows the antenna to extend circumferentially around the hub portion, increasing the effective antenna area and improving data transmission while maintaining manufacturing simplicity
5Reliability
If a complex manufacturing process with assembly of plastic flange on glass barrel is used, then RFID tag integration is achieved, but the manufacturing complexity increases
Solution Approach 1:
The patent merges the RFID tag integration with the existing cover manufacturing process. The tag is positioned and secured within the annular space between the outer and inner casings during the same manufacturing operations, eliminating the need for separate assembly steps and reducing overall manufacturing complexity while achieving reliable RFID integration
