Motivational Spirometry System with Dual-Feedback Animation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spirometry systems face challenges in motivating children to improve both peak flow rate and total volume measurements during breathing therapy, as existing systems primarily focus on single performance metrics and may not effectively engage young users.
Innovation Solution
A motivational spirometry system that uses a display to show animated feedback, such as a fireman extinguishing a fire, where the water flow magnitude reflects peak flow rate and fire extinguishment degree reflects total volume, with adjustable goal values based on user demographics and past performance, to encourage both peak flow and total volume improvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing spirometry systems use single performance metric feedback (e.g., only peak flow rate or only total volume), then the system is simple to implement, but it cannot effectively motivate children to improve both peak flow rate and total volume
Solution Approach 1:
The motivational feedback system is segmented into two independent visual components: a water flow indicator representing peak flow rate and a fire extinguishment indicator representing total volume. Each component can be controlled independently based on the respective performance metric, allowing the system to provide targeted motivation for each parameter without requiring a completely new complex system.
Solution Approach 2:
The patent introduces an intermediary motivational animation system that translates raw spirometry data into engaging visual metaphors (fireman extinguishing fire). This intermediary layer bridges the gap between clinical measurements and child engagement, making the feedback system more effective without requiring direct complex interactions with the measurement hardware.
2Reliability
If the system provides real-time motivational feedback, then user engagement and measurement quality improve, but the system complexity and processing requirements increase
Solution Approach 1:
The system implements real-time feedback by continuously monitoring spirometry measurements and dynamically updating the motivational animation based on current performance. The water flow and fire extinguishment visual elements respond immediately to changes in peak flow rate and total volume, providing continuous motivation that improves measurement quality without requiring complex predictive or delayed systems.
Solution Approach 2:
The patent utilizes visual color changes and intensity variations in the motivational animation to represent different performance levels. The fire extinguishment animation transitions through visual states (fire intensity, water flow magnitude) that correspond to measurement values, providing intuitive real-time feedback through simple visual processing rather than complex data visualization.
3Adaptability or versatility
If the system uses standardized normative values for all users, then the system is easy to operate, but it cannot account for individual differences in age, sex, and height
Solution Approach 1:
The system dynamically adjusts the motivational goals and feedback thresholds based on user demographics (age, sex, height). Instead of using fixed standardized values, the system adapts the peak flow rate and total volume targets individually for each user, making the motivational feedback relevant to their specific capabilities while maintaining ease of operation through automated adjustment.
Solution Approach 2:
The patent changes the reference parameters used for evaluation based on user characteristics. The system stores demographic information and automatically selects appropriate normative values or target values corresponding to the user's age, sex, and height, thereby individualizing the feedback without requiring manual configuration or complex user input.

AI summary
A method is disclosed for motivating a user of a spirometry system having a display screen, an air-tube, a flow measurement sensor operatively associated with the air-tube, a display screen, and an associated processor. A motivational animation is displayed on the display screen having a first aspect that reflects a relative evaluation of a determined peak flow rate to a goal value therefor and having a second aspect that reflects a relative evaluation of a determined total flow volume to a goal value therefor. The processor repeatedly updates the motivational animation during the period of use of the spirometer to reflect the degree of achievement of both of the goal values by the user.
