Medicament Delivery Device Secure Authentication Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medicament delivery devices face risks of unauthorized use and accidental activation, leading to misuse or wastage of expensive and vital medications, as existing security mechanisms can be overridden or manipulated.
Innovation Solution
Incorporating a unique identification module with mechanical or electrical keying elements that must match specific medicament delivery devices, combined with biometric or code-based authentication, to prevent activation unless authorized, and communication circuits for external verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an activation preventing mechanism is added to secure the medicament delivery device, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The activation preventing mechanism is divided into separate functional components: an identification module with keying elements, a blocking element, and a drive element. This segmentation allows each component to perform a specific function while maintaining overall system security without excessive complexity.
Solution Approach 2:
The blocking element is positioned in advance to prevent activation before authorization is verified. The identification module must be properly engaged and authenticated before the blocking element is moved to allow activation, ensuring security is established before use.
2Reliability
If a unique identification module with keying elements is implemented, then the reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The identification module is designed to be self-contained with integrated keying elements that automatically engage with the medicament delivery device. The unique pattern recognition and authentication occur automatically when the module is properly attached, reducing manual intervention while maintaining security.
3Adaptability or versatility
If the identification module is made attachable and reusable across multiple devices, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The identification module is designed as a universal component that can be attached to multiple medicament delivery devices. It contains a unique identification pattern that is recognized by each device, allowing the same module to securely authenticate across different devices while maintaining individual device security through the unique pattern recognition system.
