Deployable Grip for Drug Delivery Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Administering injections presents challenges for users and healthcare professionals due to risks and difficulties in handling and ensuring the proper use of drug delivery devices, such as pre-filled syringes.
Innovation Solution
A body arrangement for a drug delivery device featuring deployable parts that transition from a compact to an enlarged state, providing an improved grip area and visual indicators to ensure proper use, including telescoping, folding, or rotatable mechanisms with springs for automatic deployment and non-return features to prevent reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the body arrangement is kept compact for storage and transport, then the device portability is improved, but the grip area is reduced making handling difficult
Solution Approach 1:
The body arrangement includes deployable body parts that can transition between a compact configuration for storage/transport and a deployed configuration with enlarged grip area for handling. The grip feature is deployable from the body, allowing the device to adapt its form factor based on operational needs.
2Reliability
If visual indicators are added to show device use status, then user safety is improved, but device complexity increases
Solution Approach 1:
The deployable body part itself serves as a visual indicator through its deployment state. When the grip feature is deployed or the body arrangement is in its expanded configuration, it provides visual confirmation that the device is ready for use or has been used, eliminating the need for separate indicator mechanisms.
3Reliability
If non-return features are implemented to prevent reuse, then safety is improved, but ease of operation is reduced
Solution Approach 1:
The body arrangement incorporates non-return features that prevent the deployable body part from returning to its original configuration after deployment. This ensures the device cannot be reused, providing safety through a one-time use mechanism that is integrated into the deployment action itself.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances handling and safety by providing a larger grip area and visual confirmation of device use, preventing accidental reuse and improving user safety and handling of drug delivery devices.
Implementation Method 1
at least one spring is arranged to bias the at least one deployable body part towards the deployed state
Data Source
AI summary
The present disclosure relates to a body arrangement for a drug delivery device, comprising at least one deployable body part arranged to be moved from a compact state into a deployed state, wherein the body part in the deployed state provides an enlarged grip area compared to the compact state.
