Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional gauge indicator is used to measure lung volume, then the device can provide basic measurement functionality, but it fails to differentiate between sustained maximal inspiration and rapid inspiratory bursts
Solution Approach 1:
The patent employs a helical (spiral) tube instead of a straight tube to create a curved path that the ball must follow. This curved geometry requires sustained inhalation pressure to overcome gravity and friction along the spiral path, thereby differentiating SMI from rapid shallow breathing without complex electronics
Solution Approach 2:
The device uses a movable ball indicator that dynamically responds to inhalation pressure in real-time. The ball's position along the helical tube changes continuously with breathing effort, providing visual feedback that distinguishes between sustained maximal inspiration and rapid inspiratory bursts
2Ease of manufacture
If a simple gauge is used, then the device is easy to manufacture, but it lacks motivation for pediatric patients to continue using the spirometer
Solution Approach 1:
The patent incorporates multiple colored balls (red, yellow, green) that represent different achievement levels. This color-coding system provides visual motivation for pediatric patients while maintaining simple manufacturing processes using standard plastic molding techniques
Solution Approach 2:
The device provides immediate visual feedback through the ball's position and color, allowing patients to see their progress in real-time. This feedback mechanism motivates continued use by showing tangible results of breathing exercises without requiring complex digital displays
3Reliability
If proper Sustained Maximal Inspiration is not achieved, then lung recovery is prolonged and hospital stays are extended, but traditional spirometers do not provide adequate motivation for patients
Solution Approach 1:
The helical tube with colored balls provides immediate visual feedback that confirms whether the patient has achieved sustained maximal inspiration. The ball reaches higher levels and changes color to indicate proper technique, ensuring reliable breathing exercises while maintaining patient compliance through gamification
Solution Approach 2:
The device allows patients to self-monitor and self-correct their breathing technique by observing the ball's position. The visual indicator system enables patients to independently achieve proper SMI without constant provider supervision, improving both reliability and ease of operation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The spirometer effectively motivates users to perform sustained maximal inspirations, strengthens respiratory muscles, and aids in lung capacity development, while being simple to operate and cost-effective for large-scale production.
Implementation Method 1
The spirometer can further include a reciprocating gate adjacent to an outlet of the helical tube and wherein the reciprocating gate is coupled to a push down button. Here, the push down button is configured to align an aperture of the reciprocating gate with an outlet of the helical tube.
Implementation Method 2
The method can include from a drawtube, wherein the drawtube is coupled to an air tube, and wherein the air tube is coupled to a helical tube. The method can further include building low pressure within the air tube and the helical tube through the inhalation, wherein the low pressure causes an object to travel through the helical tube

AI summary
An incentive spirometer is provided that allows a user to achieve Sustained Maximal Inspiration (SMI) through the use of helical tubes. Specifically, the incentive spirometer includes three chambers, wherein each chamber includes a ball traveling upwards through three helical tubes in sequential order and subsequently dropping down through a basket. Here, each of the helical tubes and corresponding baskets generally represent various levels of lung capacity achieved with repetitive use and operation of the incentive spirometer.
