Solution Overview

Problem

Current incentive spirometers fail to differentiate between sustained maximal inspiration and rapid inspiratory bursts, lack motivation for pediatric patients, and result in improper or sporadic use, leading to prolonged lung recovery and hospital stays.

Innovation Solution

A three-dimensional incentive spirometer with helical tubes and baskets that require sustained inhalation to move a ball through a spiral path, incorporating a push-down button mechanism and adjustable air flow to align with the user's lung capacity levels, providing a visually engaging and motivating experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a simple gauge indicator is used to show lung volume, then the device is easy to manufacture and operate, but it cannot differentiate between sustained maximal inspiration and rapid inspiratory bursts

Engineering Contradiction:
Improvebreathing pattern differentiationVSAvoiddevice structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs a helical (spiral) tube instead of a straight tube to create a curved path that the ball must traverse. This helical geometry forces the ball to move in a controlled spiral pattern during inhalation, allowing the system to distinguish between sustained maximal inspiration (where the ball completes the helical path) and rapid inspiratory bursts (where the ball cannot complete the path due to insufficient time and pressure). The curvature of the helical tube thus provides the differentiation capability without requiring complex electronic sensors or multiple components.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Adaptability or versatility

If a traditional gauge is used, then the device structure is simple, but it lacks motivation for pediatric patients to continue using the spirometer

Engineering Contradiction:
Improveuser motivationVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent incorporates visual elements including colored zones along the helical tube and colored baskets at different heights. As the ball travels through the helical tube and reaches different colored zones, it provides visual feedback and motivation to the user. This color-based visual incentive system engages pediatric patients by making the breathing exercise more game-like and visually appealing, encouraging them to continue using the spirometer without adding complex electronic or mechanical components.
