Innovation Solution
A synthetic reed composition featuring a polymeric matrix with randomly distributed cane particles and synthetic fibers, where the cane particles are dispersed within a thermosetting or thermoplastic matrix, enhancing the reed's durability and sound mimicry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If natural cane is used to make reeds, then sound quality is improved, but durability deteriorates
Solution Approach 1:
The patent uses a composite material consisting of a synthetic polymer matrix combined with natural cane fibers and particles. This composite structure allows the reed to benefit from both the durability of synthetic materials and the acoustic properties of natural cane, resolving the contradiction between sound quality and durability
Solution Approach 2:
The patent modifies the physical and chemical parameters of the synthetic matrix by incorporating cane particles at specific concentrations (0.5% to 10% by volume) and using specific particle size ranges (10-500 micrometers). These parameter changes enable the synthetic reed to achieve acoustic properties similar to natural cane while maintaining synthetic durability
2Duration of action of stationary object
If synthetic materials are used to make reeds, then durability is improved, but sound quality deteriorates
Solution Approach 1:
The patent creates a composite material where synthetic polymer serves as the base matrix and natural cane fibers and particles are dispersed within it. This composite approach allows the reed to maintain the durability advantages of synthetic materials while incorporating the acoustic properties of natural cane through the dispersed cane elements
Solution Approach 2:
The patent applies local quality by distributing cane particles and fibers throughout the synthetic matrix at varying concentrations. The cane particles are randomly distributed within the synthetic matrix substrate at a concentration within a range of approximately 0.5% to 10% by volume, creating local regions that mimic natural cane's acoustic properties while maintaining overall synthetic durability
3Strength
If synthetic reeds are made with rigid makeup, then durability is improved, but warmth and natural sound deteriorates
Solution Approach 1:
The patent changes the physical parameters of the synthetic reed by incorporating cane particles with specific size ranges (10-500 micrometers) and concentrations (0.5% to 10% by volume). These parameter changes modify the reed's vibrational characteristics to produce a warmer, more natural sound while maintaining the underlying synthetic structure's durability
Solution Approach 2:
The patent creates a flexible composite structure where the synthetic matrix is modified with cane particles to achieve optimal flexibility. This flexibility allows the reed to vibrate in a manner that produces warmth and natural sound characteristics, countering the overly rigid nature of conventional synthetic reeds

AI summary
A synthetic reed for use with a woodwind instrument includes a synthetic resin matrix with randomly distributed suspended cane particles. Synthetic fibers, which may comprise one or more different material filaments, may also be impregnated within resin matrix. The cane particles can be present in a concentration of approximately 0.5-10% by volume and at least a majority of the cane particles in the resin matrix can be less than 100 micrometers. The matrix may be formed from two components including an epoxy resin component and a hardener component. The reed exhibits improved strength properties usually provided by synthetics with the warmer sonic properties associated with natural cane reeds and preferred by musicians.
