Injection Add-On Memory Tag for Medicament Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injection devices and add-on devices face challenges in accurately identifying and monitoring the use of different medicament types, leading to potential mix-ups and loss of dosing history when detached from multiple devices.
Innovation Solution
Incorporation of machine-readable identifications, such as electronic RFID or NFC tags, within the injection device and its components to store and transmit device, container, and use-related data, allowing seamless data transfer and monitoring across detachable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If detachable connection is used between add-on device and injection device, then ease of operation is improved, but reliability deteriorates due to potential mix-ups and loss of dosing history
Solution Approach 1:
The patent applies preliminary action by pre-storing dosing history and device information in the machine-readable identification (memory) before detachment occurs. This ensures that even when the add-on device is detached and reattached to a different injection device, the original dosing history can be retrieved and matched correctly through the stored data, preventing loss of critical information and maintaining reliability while allowing easy detachment.
2Measurement precision
If machine-readable identification with memory is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by implementing a machine-readable identification system with memory that serves multiple functions: storing device information, recording dosing history, enabling identification and matching of components, and facilitating data transfer between devices. This multi-functional approach achieves high measurement precision for identification while minimizing the increase in device complexity by consolidating multiple functions into a single integrated component.
