Grooved Resin Reed for Stable Attachment and Easier Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resin reeds for wind instruments face challenges in stable attachment and sound-producing properties due to thin heel parts and lack of effective groove designs, leading to instability and suboptimal performance.
Innovation Solution
A reed design featuring grooves on the base part that intersect the longitudinal direction, reducing mass and enhancing flexibility and adhesion, while maintaining mechanical strength and stability, using a resin composition with high specific gravity materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the heel part of a resin reed is thinned to reduce mass, then the reed becomes easier to vibrate, but the reed becomes difficult to stably attach to the mouthpiece
Solution Approach 1:
The patent applies local quality by creating grooves only in specific regions of the reed blade while maintaining different thickness profiles in different areas. The groove pattern varies across the blade surface, with some regions having grooves and others being solid, creating localized variations in mass and flexibility that optimize both vibration and attachment stability.
Solution Approach 2:
The patent uses composite material structures by combining resin material with strategically placed grooves, creating a heterogeneous structure that optimizes both weight and mechanical properties. The groove regions provide mass reduction while the solid regions maintain structural integrity for stable attachment.
2Weight of moving object
If the reed is made thinner to decrease mass, then the reed becomes lighter, but the sound-producing property is not improved
Solution Approach 1:
The patent creates localized variations in the reed structure through grooves of different depths, widths, and patterns in specific regions. This local quality approach allows the reed to have reduced mass overall while maintaining adequate thickness in critical sound-producing areas, thereby improving vibration characteristics without sacrificing sound quality.
Solution Approach 2:
The groove patterns create dynamic flexibility variations across the reed blade, allowing different regions to respond differently to vibration. This dynamic structure enables the reed to vibrate more efficiently while maintaining the mass necessary for proper sound production.
3Weight of moving object
If grooves are added to the reed to reduce mass, then the reed becomes lighter, but player discomfort increases
Solution Approach 1:
The patent carefully positions grooves in regions that do not contact the player's lips or teeth, concentrating groove patterns in the blade area while keeping the tip and heel regions smoother. This local quality approach reduces mass through grooves while avoiding player discomfort by excluding sensitive contact areas from groove placement.

AI summary
A reed for a mouthpiece of a wind instrument includes a base part and a vamp. The base part extends in a first direction and includes a first surface and a second surface opposite to the first surface. At least one of the first surface or the second surface includes at least one groove extending along a second direction that intersects the first direction. The vamp extends from the base part along the first direction.
