Integrated Dose Counter With Electronic Adherence Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical dose counters in metered dose inhalers (MDIs) only provide information on the number of doses dispensed or remaining, without tracking when the doses were taken or how they were administered.
Innovation Solution
Integration of a mechanical dose counter with an electronic module that records and tracks when doses are dispensed, providing additional data on adherence and compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a mechanical dose counter is integrated with an electronic module to track dose administration time and adherence, then the information completeness and patient compliance monitoring capability are improved, but the device complexity increases
Solution Approach 1:
The patent combines a mechanical dose counter with an electronic module into an integrated system. The mechanical counter continues to mechanically track dose dispensing while the electronic module parallelly records timing and adherence data, merging two counting approaches into a unified device that captures both mechanical dose count and temporal usage patterns.
Solution Approach 2:
The integrated system performs multiple functions: the mechanical counter provides real-time dose counting, while the electronic module simultaneously records administration times, calculates adherence metrics, and can communicate with external devices. This multi-functional approach allows a single device to serve both mechanical counting and electronic monitoring purposes.
2Loss of information
If an electronic module is added to record dose dispensing information, then the data tracking capability is improved, but the manufacturing cost increases
Solution Approach 1:
The system is segmented into independent functional modules: a mechanical dose counter subsystem and an electronic tracking subsystem. This segmentation allows each module to be manufactured separately using established processes, then integrated through standardized interfaces, reducing overall manufacturing complexity and cost compared to a fully integrated electronic system.
Solution Approach 2:
The mechanical dose counter operates autonomously to track dose dispensing without requiring electronic power or processing, while the electronic module only activates to record data when the mechanical counter triggers an event. This self-service approach minimizes electronic component requirements and power consumption, reducing manufacturing costs.
3Adaptability or versatility
If both mechanical counting and electronic recording are integrated, then the adherence monitoring capability is improved, but the device structure becomes more complex
Solution Approach 1:
The mechanical dose counter acts as an intermediary that triggers electronic recording events. When the mechanical counter detects a dose dispensing event through mechanical movement, it activates the electronic module to record the timing and adherence data, creating a simple event-driven interface between the two systems that minimizes structural complexity.
Solution Approach 2:
The patent replaces purely mechanical adherence tracking with an electronic recording system that captures precise timing data. The electronic module substitutes for complex mechanical timing mechanisms by using electronic timestamps and digital record-keeping, simplifying the overall structure while enhancing monitoring capabilities.
