Bent Front Surface Piece Thyroid Cartilage Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dysphonia treatment tool struggles to securely attach to the thyroid cartilage due to its tapered shape and varying projection angles across individuals, leading to potential displacement and discomfort.
Innovation Solution
The dysphonia treatment tool features a front surface piece with a bending angle of 10-50 degrees and a thickness of 0.05-0.6 mm, allowing for easy adjustment and secure fitting along the thyroid cartilage, with strategically placed holes to distribute stress and prevent concentration around them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the front surface piece is made straight to simplify the structure, then the device complexity is reduced, but the treatment tool cannot conform to the tapered shape of thyroid cartilage and may float from the cartilage surface
Solution Approach 1:
The front surface piece is designed with a bent shape instead of being straight, allowing it to conform to the tapered projection angle of the thyroid cartilage. The bending angle is set between 10-50 degrees to match the natural anatomy, ensuring the treatment tool remains securely attached without floating from the cartilage surface.
Solution Approach 2:
Different sections of the front surface piece have different properties: the intermediation section is bent to match the local tapered geometry of the thyroid cartilage, while other sections maintain appropriate rigidity for structural support and clamping functionality.
2Strength
If the front surface piece is made thicker to increase rigidity, then the strength is improved, but the ease of bending and adjustment is reduced
Solution Approach 1:
The thickness of the front surface piece is optimized to a specific range (0.05-0.6 mm) that balances rigidity and bendability. This parameter selection allows the material to maintain sufficient strength while remaining easily adjustable to the required bending angle for conforming to thyroid cartilage geometry.
3Adaptability or versatility
If the bending angle is increased to better conform to thyroid cartilage shape, then the adaptability is improved, but the structural stability may be compromised
Solution Approach 1:
The bending angle is controlled within a specific range (10-50 degrees) that provides optimal adaptability to thyroid cartilage shapes while maintaining structural stability. This parameter optimization ensures the front surface piece can conform to varying projection angles without compromising the overall structural integrity of the treatment tool.

AI summary
Object:Provided is a dysphonia treatment tool in which a front surface piece is bent.Resolution means:A dysphonia treatment tool includes a plurality of clamping sections (1, 1) each including a front surface piece (1a) disposed from a cut end surface of thyroid cartilage incised to a front surface, and a rear surface piece (1b) disposed on a rear surface of the thyroid cartilage, and being fitted respectively to cut ends of the thyroid cartilage that are opposite each other, and a bridging section (2) linking the plurality of clamping sections (1, 1) to each other. The front surface piece (1a) is bent in an intermediation section between a base end and a distal end of the front surface piece (1a).
