Wearable Injection Device Body Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable injection devices, such as the EpiPen, can be forgotten during emergencies and are often administered too late, leading to fatal consequences due to the rapid onset of conditions like anaphylaxis, and there is a need for a device that ensures immediate and rapid access to medication for conditions like diabetes and heart problems.
Innovation Solution
A wearable injection device designed to be attached to the body, featuring a closable opening for rapid skin access, a user-friendly activation mechanism, and a medication container with a self-cooling graphene paste, allowing for quick and hygienic administration of medications like epinephrine or insulin, and the ability to be easily replaced or exchanged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the injection device is carried in a pocket or bag, then it is portable, but it can be forgotten during emergencies
Solution Approach 1:
The device is attached to the body in advance (on the wrist or arm) so that it is already in position and cannot be forgotten during an emergency. The attachment means ensures the device remains on the body at all times, eliminating the risk of forgetting it at home or in a bag.
2Reliability
If the device requires multiple steps to access medication, then it is safe from accidental activation, but it takes too long to administer during emergencies
Solution Approach 1:
The device is divided into separate functional components: a safety cover that protects the activation mechanism, a medication container with injection needle, and an attachment mechanism. The safety cover must be removed before activation, providing a simple single-step access that prevents accidental activation while enabling rapid deployment when needed.
3Speed
If the injection device is always accessible, then rapid administration is possible, but the medication space is vulnerable to contamination
Solution Approach 1:
The medication space is sealed with a protective cover or membrane that can be quickly opened or pierced during activation. This seal prevents contamination when the device is stored on the body, while allowing rapid access to the medication when activation occurs.
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
The device ensures the user always carries the injection device, allowing for immediate and accurate administration of medication, significantly increasing the chances of survival and reducing severe consequences, while maintaining hygiene and usability.
