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

VSEngineering 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

Engineering Contradiction:
ImproveportabilityVSAvoidavailability during emergency
Core Design Contradiction:
Ease of operationVSReliability

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improveprotection from accidental activationVSAvoidtime to administer medication
Core Design Contradiction:
ReliabilityVSLoss of time

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.

Inventive Principle:
Principle #1Segmentation

3Speed

If the injection device is always accessible, then rapid administration is possible, but the medication space is vulnerable to contamination

Engineering Contradiction:
Improveaccess speedVSAvoidcontamination risk
Core Design Contradiction:
SpeedVSObject-affected harmful factors

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.

Inventive Principle:
Principle #30Flexible shells and thin films
