Vocalization Appliance for Vocal Cord Closure Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vocalization appliances are ineffective in correcting vocal dysfunctions related to vocal cord closure, such as paralysis, lack of closure ability, and poor closure, which hinders healthy pronunciation and speech resonance.
Innovation Solution
A vocalization appliance comprising an inner arc plate, an outer arc plate, and partitions that form separate accommodating rooms for upper and lower incisors, with extending ends to separate mouth corners and a tongue depressor to relax tongue muscles, promoting passive vocal cord closure and resonance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional vocalization appliance is used to maintain distance between upper and lower teeth, then teeth positioning is improved, but vocal cord closure function is not effectively corrected
Solution Approach 1:
The appliance is divided into multiple functional components: upper and lower arc plates for teeth positioning, tongue depressor for tongue control, and lateral extensions for mouth corner separation. Each segment addresses a specific aspect of vocal cord closure, working together to achieve comprehensive correction rather than relying on a single mechanism.
Solution Approach 2:
The appliance acts as an intermediary device that indirectly influences vocal cord closure by modifying oral geometry. By maintaining proper teeth positioning, depressing the tongue, and separating mouth corners, it creates favorable conditions for vocal cord closure without directly manipulating the vocal cords themselves.
2Reliability
If mouth distance is increased to separate lips and muscles, then passive vocal cord closure is promoted, but device complexity increases
Solution Approach 1:
Multiple functions are merged into a single integrated appliance structure. The arc plates, tongue depressor, and lateral extensions work together as one unified device that simultaneously achieves teeth positioning, tongue control, and mouth corner separation, promoting passive vocal cord closure without requiring multiple separate devices.
Solution Approach 2:
The appliance performs multiple functions within a single structure: positioning upper and lower teeth, depressing the tongue, separating mouth corners, and maintaining optimal oral geometry. This multi-functionality achieves comprehensive vocal cord closure support without proportionally increasing device complexity.

AI summary
A vocalization appliance for assisting vocal cord closure training includes: an inner arc plate, an outer arc plate, and two partitions which are oppositely disposed, wherein the inner arc plate is opposite to the outer arc plate, and the two partitions are placed with an interval between the inner arc plate and the outer arc plate; the two partitions, the inner arc plate and the outer arc plate are enclosed to form an accommodating cavity, and the accommodating cavity is separated into an upper accommodating room and a lower accommodating room along a height direction; the upper accommodating room accommodates upper incisors while the lower accommodating room accommodates lower incisors; opposite side ends of the inner arc plate respectively extend away from the accommodating cavity, and opposite side ends of the outer arc plate also respectively extend away from the accommodating cavity, thereby separating mouth corners.
