Semi-Occluded Vocal Exercise Straw With Adjustable Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semi-occluded vocal tract exercise methods, such as using drinking straws, fail to provide customizable resistance levels to accommodate individual user needs and preferences, which can vary due to physiological differences and vocal demands.
Innovation Solution
A customizable vocal straw apparatus with variable resistance adjustment through apertures and a tapered lumen design, allowing users to select desired resistance levels by blocking apertures and adjusting airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-diameter straw is used for SOVT exercises, then the device structure is simple, but it cannot accommodate individual user needs and preferences for different resistance levels
Solution Approach 1:
The straw is segmented into multiple sections with different aperture configurations. Each section provides a different resistance level, allowing users to select the appropriate segment for their needs. This segmentation enables variable resistance without requiring a completely complex adjustable mechanism.
Solution Approach 2:
The straw incorporates a tapered lumen design where the internal diameter varies along the length of the straw. This dynamic geometry allows the resistance to change progressively along the airflow path, providing adaptable resistance levels while maintaining a relatively simple single-piece structure.
2Stress or pressure
If the straw inner diameter is reduced to increase resistance, then back-pressure increases, but resistance becomes too high for most users
Solution Approach 1:
By segmenting the straw into sections with different aperture sizes, users can select a section with appropriate resistance. This allows back-pressure to be optimized for each user's capability without requiring a single extremely narrow diameter that would be too restrictive for most users.
Solution Approach 2:
Different sections of the straw have different local aperture qualities. Some sections have larger apertures for lower resistance, while others have smaller apertures for higher resistance. This local variation in quality allows users to match the resistance to their specific needs without the entire straw being overly restrictive.
3Ease of operation
If the straw inner diameter is increased to decrease resistance, then ease of operation improves, but back-pressure becomes insufficient for effective exercise
Solution Approach 1:
The segmented design with multiple aperture configurations allows users to select sections with larger diameters for easier operation when needed, while still having access to sections with smaller diameters when higher back-pressure is required for effective exercise.
Solution Approach 2:
The single straw device serves multiple functions by incorporating different aperture sections, effectively becoming a multi-functional tool that can provide both low-resistance and high-resistance exercise options, accommodating a wide range of user needs and progression levels.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables personalized vocal tract exercises by providing a wide range of resistance options, accommodating varying user needs and preferences, enhancing vocal performance and health.
Implementation Method 1
One or more apertures of uniform or non-uniform dimensions are disposed over the elongated body longitudinally and/or axially. The central lumen puts the apertures and the exit in fluid communication with the inlet.
Implementation Method 2
Increased inertance of the vocal tract is the keeping of air in the vocal tract's contained acoustic system by restricting the ease with which air flows out of the vocal tract, in this case by increased back-pressure.
