Drug Delivery Device Pairing Code Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drug delivery devices face challenges in securely establishing a communication link between electronic data logging devices and external electronic devices, requiring a pairing code that is accessible only to authorized personnel while preventing unauthorized access.
Innovation Solution
A drug delivery device design where a pairing code is visually identifiable only when specific device components are in a defined positional state, with the code being concealed otherwise, and optionally split across multiple components that must be aligned or recombined to form the complete code.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pairing code is made visible and accessible, then ease of operation is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The pairing code is segmented into multiple code portions distributed across different device components. Each component contains only a portion of the complete pairing code, and the components must be assembled or aligned in a specific configuration to reveal the complete code. This segmentation prevents unauthorized access while maintaining ease of operation for authorized users who can properly assemble the device.
2Object-affected harmful factors
If the pairing code is concealed to prevent unauthorized access, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The device components are pre-configured with specific code portions during manufacturing. The design anticipates that authorized users will need to assemble the device in a specific way to access the pairing code. This preliminary configuration ensures that when the device is properly assembled, the pairing code becomes accessible without requiring additional security steps, thus maintaining ease of operation for authorized users.

AI summary
The present disclosure relates to a method of pairing an electronic data logging device of a drug delivery device with an external electronic device and to a respective drug delivery device. The drug delivery device comprises a housing configured to accommodate the medicament and to receive and/or mechanically engage with the electronic data logging device. The drug delivery device further comprises a first device component and a second device component. The first device component is movable relative to the second device component from a first positional state to a second positional state. The first device component comprises a first outer surface, and the second device component comprises a second outer surface. At least one of the first outer surface and the second outer surface comprises a first code portion of a pairing code for establishing a communication link between the electronic data logging device and an external electronic device.
