Medicine Delivery Accessory with Color-Coded Dose Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medicine delivery devices lack effective mechanisms for tracking dosing compliance and providing clear, unambiguous visual cues to users about the safety and timing of administering medicine doses, particularly for chronic conditions like diabetes.
Innovation Solution
An accessory device for medicine delivery devices featuring a user interface with selectively illuminated lights and symbols, such as green, yellow, and red LEDs, to indicate safe dosing times and actions, along with a detector to monitor attachment and detachment, and an electronics unit to control light sequences based on predefined or dynamically determined intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing medicine delivery devices are used without additional accessories, then the device structure remains simple, but the ability to track dosing compliance and provide clear visual cues is insufficient
Solution Approach 1:
The system is divided into separate functional modules: a dosing delivery device and a separate accessory device. The accessory device contains the tracking and visual indication functionality, while the delivery device maintains its original simple structure for administering medicine. This segmentation allows the tracking features to be added without complicating the core delivery mechanism.
Solution Approach 2:
The accessory device acts as an intermediary between the dosing delivery device and the user. It receives dosing event information from the delivery device and translates it into clear visual cues (light sequences) that guide the user through the dosing process, thereby improving compliance without requiring the delivery device itself to become complex.
2Loss of information
If multiple lights are used to indicate different dosing states, then user understanding of safe dosing times improves, but the device complexity increases
Solution Approach 1:
The accessory device uses a multi-color light indicator system where different colors represent different dosing states: green indicates the dosing window is open and dosing is safe, yellow indicates the dosing window is closing or recently opened, and red indicates the dosing window is closed. This color-coding system provides clear, intuitive visual information to users without requiring complex displays or text.
Solution Approach 2:
The light sequence operates periodically, cycling through different color states to indicate the passage of time within the dosing window. The light changes colors at predetermined time intervals, providing continuous visual feedback to the user about the current dosing status without requiring constant user input or complex processing.
3Measurement precision
If detectors monitor attachment and detachment of the accessory, then dosing event detection accuracy improves, but the device complexity increases
Solution Approach 1:
The detector automatically detects when the accessory is attached to or detached from the dosing delivery device without requiring any user action. The system self-monitors the connection state and uses this information to determine when dosing events have occurred, eliminating the need for manual tracking or complex user interfaces for event detection.
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 user compliance by providing clear visual cues and tracking dosing events, reducing confusion and ensuring safe administration times, thereby improving management of chronic conditions.
Implementation Method 1
The user interface includes first and second lights configured to be selectively illuminated... the first light is a green light and the second light is a red light... the user interface further includes a third light configured to be selectively illuminated... the third light may be a yellow light
