Innovation Solution
A sensor device coupled with a medicament device that detects usage parameters and provides real-time guidance through auditory or visual indicators, adapting to different types of medicament devices by processing specific parameters like shake duration, actuation intervals, and priming steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users follow specific handling techniques for different medicament devices, then medication delivery accuracy is improved, but device complexity and user operation difficulty increase due to varying procedures for different device types
Solution Approach 1:
The patent employs feedback mechanisms through sensors that detect usage parameters (shaking, actuation, priming) and provide real-time guidance to users. This closed-loop system monitors whether proper technique is being followed and offers corrective feedback, ensuring accurate medication delivery without requiring users to memorize complex device-specific procedures.
Solution Approach 2:
The system enables self-service by having the medicament device automatically provide usage guidance through integrated sensors and indicators. The device itself monitors its own usage parameters and guides the user through proper technique, eliminating the need for external instruction or complex user knowledge of different device types.
2Reliability
If real-time guidance is provided through sensors and indicators, then user errors are reduced, but device complexity increases due to additional components
Solution Approach 1:
The patent implements a universal sensor device that can be coupled to multiple different types of medicament devices. This single multi-functional sensor unit detects usage parameters across various device types, reducing the need for multiple specialized sensors and thereby limiting the increase in device complexity while maintaining reliability.
Solution Approach 2:
The sensor device acts as an intermediary between the medicament device and the user, translating physical usage parameters into actionable guidance. This intermediary layer simplifies the overall system by centralizing the detection and feedback functions in a single component rather than distributing complexity across multiple elements.
3Measurement precision
If personalized guidance is provided for each medicament device type, then medication delivery accuracy is enhanced, but loss of information increases due to varying parameters across device types
Solution Approach 1:
The system handles parameter variations across different medicament device types by dynamically adjusting detection thresholds and guidance criteria based on the specific device being used. The sensor device adapts its measurement parameters and evaluation criteria to match the characteristics of each device type, ensuring accurate personalized guidance without information loss.
