Detachable Dose Detection Module for Reusable Injection Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medication delivery devices lack the capability to automatically detect and record the amount of medication delivered during each injection event, requiring manual tracking by patients, and there is a need for a removable and reusable dose detection device that does not alter the functionality of the delivery device.
Innovation Solution
An attachable and detachable dose detection module that operates with the delivery device, using mechanical keying and color coding for compatibility, and includes redundant sensors to detect the delivered dose, record it, and transmit the data wirelessly, while maintaining the device's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a dose detection module is integrated into the medication delivery device, then automatic dose detection and recording capability is improved, but device complexity increases
Solution Approach 1:
The dose detection module is designed as a separate, detachable unit that can be removed from the medication delivery device. This segmentation allows the detection functionality to be added without permanently increasing the complexity of the core delivery device, while still providing automatic dose detection when the module is attached.
Solution Approach 2:
The dose detection module is designed to be compatible with multiple different medication delivery devices through standardized coupling mechanisms. This multi-functionality allows a single detection module to serve various devices, reducing overall system complexity while maintaining automatic detection capabilities across different platforms.
2Adaptability or versatility
If a detachable dose detection module is used, then adaptability and reusability are improved, but measurement precision may worsen due to attachment variability
Solution Approach 1:
The coupling interface between the dose detection module and the medication delivery device incorporates asymmetric mechanical keying features with unique geometric profiles. This asymmetric design ensures that only correctly matched modules and devices can be attached, preventing attachment variability and maintaining measurement precision while enabling reusability across compatible devices.
Solution Approach 2:
The coupling interface incorporates color-coded identification features that provide visual feedback to users about proper module-device compatibility. Different colors indicate different coupling types or configurations, ensuring that users attach the correct module to the correct device, thereby maintaining measurement accuracy while enabling broad adaptability and reusability.
3Ease of operation
If mechanical keying and color coding are implemented for compatibility, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The coupling interface incorporates color-coded identification features that provide intuitive visual feedback to users about proper module-device compatibility. Different colors indicate different coupling types or configurations, making it extremely easy for users to identify and attach the correct module without requiring technical knowledge, while the color coding itself is integrated into the coupling mechanism rather than being a separate complexity layer.

AI summary
The present disclosure relates to a dose detection system and method for a medication delivery device. The dose detection system may include a dosing component attached to an actuator and rotationally and axially moveable relative to a coupling component attached to a dose setting member. The dose detection system may further comprise a module including an electronic sensor operative to detect a relative rotation of the coupling component and the dosing component to detect a dose delivered by the medication delivery device.
