Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medicament inhalers face challenges with monitoring patient usage, particularly in preventing overuse of reliever medicaments and addressing poor compliance with preventer medicaments, which can lead to reduced effectiveness and potential exacerbation events.
Innovation Solution
A releasably attachable device for medicament inhalers that includes an optical dose counter and an electronic control module, allowing for monitoring of patient usage without modifying the inhaler, and enabling continuous data collection across multiple inhaler and medicament changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an optical dose counter is integrated into the inhaler, then patient usage monitoring is improved, but device complexity increases
Solution Approach 1:
The monitoring device is segmented into separate functional modules: an optical dose counter module, an electronic control module, and a wireless communication module. This allows the monitoring functionality to be added without integrating complex structures directly into the inhaler body, thus improving monitoring accuracy while managing device complexity through modular design.
Solution Approach 2:
An optical intermediary system is used to detect dose dispensing events. The optical sensor detects changes in light transmission or reflection that occur when the inhaler is actuated, providing accurate usage monitoring without requiring direct mechanical contact or complex integration with the inhaler's mechanical components.
2Loss of information
If continuous monitoring across multiple inhalers is enabled, then compliance tracking is improved, but data management complexity increases
Solution Approach 1:
The electronic control module is designed with universal functionality that allows it to operate with multiple different inhaler types and medicament containers. It can continuously track usage data across different inhalers by identifying and resetting the dose counter for each new inhaler, thereby maintaining compliance data continuity without requiring separate monitoring systems for each inhaler.
Solution Approach 2:
The system incorporates feedback mechanisms where the electronic control module receives optical signals from the dose counter, processes this information to determine usage events, and maintains a running total of cumulative doses. This feedback loop enables continuous compliance tracking while the module automatically manages data transitions between different inhalers, reducing the complexity of data management through centralized processing.
3Adaptability or versatility
If the device is made releasably attachable, then adaptability is improved, but connection reliability may worsen
Solution Approach 1:
The device employs a dynamic attachment mechanism that allows the monitoring unit to be easily connected to and disconnected from different inhalers. The releasable connection uses spring-loaded contacts and snap-fit structural elements that provide stable electrical and mechanical connection during use, while allowing simple attachment and detachment. This dynamic design maintains connection reliability during operation while enabling high adaptability across different inhaler types.
