Telescopic Vocal Training Device with Variable Aperture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vocal training devices for semi-occluded vocal tract (SOVT) exercises lack adjustability and feedback mechanisms, leading to limited resistance options and user convenience, particularly with fixed aperture straws contributing to environmental issues and complex, bulky devices with water requirements.
Innovation Solution
A telescopic vocal training device with adjustable length and diameter, featuring a connector system and variable aperture attachments, including a breath visualization attachment and oscillating resistance generator, to provide customizable resistance and biofeedback for optimal vocal training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed aperture straw is used for SOVT exercises, then the device is simple and portable, but the resistance options are limited and environmental pollution is caused
Solution Approach 1:
The patent applies the dynamics principle by making the straw aperture variable rather than fixed. The aperture can be dynamically adjusted by changing the position of the straw relative to the water surface, allowing the resistance to be modified continuously during use. This resolves the contradiction by maintaining simplicity while enabling adaptability.
Solution Approach 2:
The patent changes the physical parameter of aperture size by varying the straw's position in water. By adjusting the submerged length of the straw, the effective aperture changes, thereby modifying the resistance offered to airflow. This parameter change enables multiple resistance options without complicating the device structure.
2Adaptability or versatility
If a complex apparatus with water chambers and tubes is used, then resistance can be varied, but the device becomes bulky and requires water
Solution Approach 1:
The patent extracts the water chamber and complex tube structure from the device, retaining only the essential water-straw interaction. By using a simple straw inserted into water rather than an integrated water chamber apparatus, the invention eliminates bulkiness while maintaining resistance variation capability through the water-straw interface.
Solution Approach 2:
The patent makes the simple straw device universal by enabling it to provide variable resistance through its interaction with water. The same simple straw structure can offer different resistance levels by adjusting its position, eliminating the need for complex dedicated resistance-adjustment mechanisms.
3Reliability
If the straw length is increased to extend the vocal tract, then vocal training benefits are improved, but the device becomes less portable
Solution Approach 1:
The patent applies dynamics by making the effective length of the straw adjustable through water immersion. The portion of the straw that extends beyond water can be varied, allowing users to optimize the vocal tract extension for training effectiveness while maintaining portability when the straw is retracted.

AI summary
A vocal training device comprises a generally cylindrical hollow body. The generally cylindrical hollow body has a first open end, a second open end, a first tube member and a second tube member. The second tube member is configured to be telescopically inserted into the first tube member, such that the length of the generally cylindrical hollow body of the vocal training device is adjustable. The vocal training device also has a connector having a portion that is configured for removable connection to the second open end of the generally cylindrical hollow body of the vocal training device and a portion configured for removable connection to a vocal training attachment member. The vocal training attachment member can be an aperture reducing attachment, a variable aperture reducing attachment, a breath visualisation attachment, a water resistance voice therapy training attachment or an oscillating resistance generator.
