Wind Instrument Reed Affixing Device with Tone Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reed affixing devices for wind instruments lack tone control functionality, are limited in adjusting cord length for various mouthpiece sizes, and fail to securely attach reeds to mouthpieces with different angles, leading to inaccurate positioning and poor sound production.
Innovation Solution
A reed affixing device with a puller mechanism that includes a spiral cord system, sound adjusting members, and adjustable length features, allowing for precise tone control and secure attachment to mouthpieces of varying sizes and angles, using a Kevlar cord and adjustable components to optimize reed vibration and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed-length cord ligature is used to secure the reed to the mouthpiece, then the ligature can be manufactured and assembled easily, but it cannot be adjusted to fit different mouthpiece sizes
Solution Approach 1:
The cord is designed with adjustable length through a puller mechanism that allows dynamic adjustment. The puller includes a hollow portion through which the cord passes, enabling the user to extend or retract the cord length as needed to accommodate different mouthpiece sizes while maintaining secure attachment.
2Device complexity
If a simple cord ligature is used to secure the reed, then the device structure remains simple, but it lacks tone control functionality
Solution Approach 1:
The invention merges the ligature function with a tone control mechanism by integrating sound adjusting members that contact the cord. These members can be positioned to press against the cord at different locations, thereby controlling the vibration characteristics and tone quality while the cord simultaneously performs its primary function of securing the reed to the mouthpiece.
3Device complexity
If a fixed-position ligature is used, then the attachment structure is simple, but it cannot accurately position the reed on mouthpieces with various angles
Solution Approach 1:
The puller mechanism provides dynamic positioning capability, allowing the ligature to be adjusted to accommodate mouthpieces with various angles. The hollow portion of the puller can be oriented to match the mouthpiece angle, and the cord can be routed through it to secure the reed in the correct position, ensuring accurate alignment regardless of the mouthpiece orientation.

AI summary
Disclosed herein is a reed affixing device for a wind instrument. The device includes a puller means disposed on an upper portion of the mouthpiece in a longitudinal direction thereof and having a puller, with hollow portions formed in the puller in the longitudinal direction of the mouthpiece. A string-shaped cord passes through the hollow portions in the form of a unidirectional spiral from a side of the puller to wind around the reed and the mouthpiece at several times, and is secured to first and last hollow portions formed, respectively, in both ends of the puller. An affixing means is fastened to a side of the puller means to secure the reed to the mouthpiece. A pair of sound adjusting members is provided on opposite sides of the reed to be in close contact with the cord that is wound several times, thus adjusting a tone of sound.
