Solution Overview

Problem

Existing wearable medical devices struggle to effectively communicate delivery status and other properties due to obstruction by clothing or body placement, limiting visibility and usability for patients.

Innovation Solution

A wearable automatic injector system with a notification device, including a visual indicator and a flexible container that changes position within a viewing window based on medicament volume, and a wristband for passive communication of device status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the device is placed on the patient's body to deliver pharmaceutical composition, then the device can provide therapy at a remote location from clinical facility, but the visual indicator is obstructed by clothing or body placement making it difficult for patients to check device status

Engineering Contradiction:
Improvepatient ability to check device statusVSAvoidobstruction by clothing
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A notification device serves as an intermediary between the automatic injector and the patient. This notification device receives status information from the injector and presents it in a location that is not obstructed by clothing, allowing patients to easily check device status without removing clothing.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The notification device is positioned on a different body part (such as the wrist) than the automatic injector (placed on the abdomen or arm). This spatial separation in another dimension allows the visual indicator to be accessible to the patient without being blocked by clothing covering the injector site.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of information

If the device provides visual feedback to communicate delivery status, then patients can be informed about device state, but the feedback cannot be easily communicated to the patient due to device obstruction

Engineering Contradiction:
Improvedelivery status communicationVSAvoidvisibility of feedback
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The notification device acts as an intermediary that receives delivery status information from the automatic injector and communicates this information to the patient through visual indicators positioned in a visible location, ensuring that delivery status is not lost and remains easily communicable.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The notification device creates a visual copy or representation of the injector's status state. Instead of relying on the injector's own visual indicators that may be obstructed, the notification device displays a visual copy of the status (such as delivery completion, low battery, or refill needed) in a location that is always visible to the patient.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If the automatic injector is worn discretely under patient's clothing, then the device provides therapy remotely and discretely, but any visual feedback from the device cannot be easily observed by the patient

Engineering Contradiction:
Improvediscrete wearabilityVSAvoidvisibility obstruction
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system is segmented into two separate components: the automatic injector that can be worn discretely under clothing for remote therapy delivery, and a separate notification device that displays visual feedback in a visible location. This segmentation allows each component to fulfill its specific function without compromising the other - the injector remains discrete while the notification device provides visible feedback.

Inventive Principle:
Principle #1Segmentation

AI summary

An administration system for delivery of a pharmaceutical composition to a patient has a delivery device configured to deliver a dose of the pharmaceutical composition to the patient and a notification device in communication with the delivery device. The notification device is configured to communicate information about a status of at least one property of the delivery device. The delivery device can be a wearable automatic injector configured to be worn on the patient's skin. The delivery device of the present disclosure may allow a user or the patient to view a status of a container. For example, the delivery device of the present disclosure may provide a simple and effective visual means of displaying fill confirmation and delivery confirmation.
