Liquid Medicine Administration Device Activity-Based Residual Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid medicine administration devices do not account for user activity, such as exercise, when estimating residual medicine amounts in the body, leading to potential underdosage or overdosage during subsequent administrations.
Innovation Solution
A portable liquid medicine administration device equipped with an activity detection unit, storage for delivered medicine data, and a calculation unit to estimate residual medicine amounts based on user activity, allowing for adjusted delivery amounts to ensure accurate administration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the liquid medicine administration device estimates residual amount based only on dosage and administration time, then the device complexity is low, but the measurement precision of residual amount estimation deteriorates due to not considering user activity
Solution Approach 1:
The patent introduces an activity detection unit as an intermediary component that detects user activity levels and provides this information to the calculation unit. This intermediary sensor allows the system to obtain additional data about user metabolism changes without fundamentally redesigning the entire device, thereby improving measurement precision while maintaining relatively simple device architecture
Solution Approach 2:
The patent replaces the simple time-based calculation mechanism with a more sophisticated calculation unit that integrates multiple parameters including dosage, administration time, and detected activity levels. This substitution of the calculation mechanism enables more precise residual amount estimation by accounting for metabolism changes caused by user activity
2Ease of operation
If the device does not consider user activity such as exercise, then the ease of operation is high, but the reliability of liquid medicine administration deteriorates due to potential underdosage or overdosage
Solution Approach 1:
The patent implements a self-service mechanism where the activity detection unit automatically detects user activity levels and the calculation unit automatically adjusts the residual amount estimation and scheduled delivery amount based on this detected activity. This eliminates the need for users to manually input or track their own activity levels, maintaining ease of operation while significantly improving administration reliability
Solution Approach 2:
The patent introduces a feedback loop where the activity detection unit continuously monitors user activity, the calculation unit processes this feedback information to recalculate residual amounts, and the control unit adjusts the scheduled delivery amount accordingly. This closed-loop feedback system ensures reliable liquid medicine administration by dynamically adapting to user metabolic changes without complicating user interaction
3Reliability
If the device calculates residual amount considering user activity, then the reliability of dosage accuracy is improved, but the device complexity increases due to additional activity detection and calculation functions
Solution Approach 1:
The patent implements multi-functionality by integrating the activity detection unit, storage unit for activity data, and calculation unit into a single cohesive system. This universal design allows the device to perform both traditional liquid medicine administration functions and activity-based residual amount estimation functions, improving dosage accuracy while avoiding the need for separate standalone devices
Solution Approach 2:
The patent merges the activity detection capability, activity data storage, and residual amount calculation functions into an integrated control unit. This combining of multiple functions into a single unified system improves dosage accuracy through activity consideration while minimizing the increase in overall device complexity by sharing common components and processing resources
