Sensor-Embedded Woodwind Reed Vibration Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing woodwind musical instrument reeds with integrated sensors face challenges in accurately detecting reed vibrations due to vibration transmission issues and player discomfort from sensor placement.
Innovation Solution
A reed design featuring a through hole for sensor insertion, allowing the sensor to be positioned on the vibrating part without exposing it to the player's lips, ensuring accurate vibration detection while maintaining a natural playing experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the sensor is attached to the fixed part of the reed, then the sensor can be positioned away from the player's lips, but the vibration detection accuracy deteriorates because vibration of the vibrating part is transmitted to the fixed part
Solution Approach 1:
The sensor part is extracted from the fixed part and repositioned to the vibrating part. The through hole enables the sensor to be located where it can directly detect vibration without interference from vibration transmission, while the connecting part maintains electrical connection to the outside world.
2Measurement precision
If the sensor is attached to the vibrating part of the reed, then the vibration detection accuracy improves, but the player experiences discomfort because the sensor is exposed on the outer surface to be touched by lips
Solution Approach 1:
The sensor part is nested within the reed structure using the through hole. The sensor is inserted through the hole and positioned on the inner surface of the vibrating part, while the connecting part extends through the hole to the outer surface for electrical connection, keeping the sensitive sensor portion hidden from player's lips.
3Measurement precision
If a through hole is created in the reed for sensor insertion, then the sensor can be correctly positioned on the vibrating part, but the reed structure becomes more complex
Solution Approach 1:
The sensor assembly is segmented into distinct functional parts: the sensor part for vibration detection positioned on the inner surface, and the connecting part for electrical connection extending to the outer surface. This segmentation allows each part to be optimized for its specific function while simplifying the overall integration process.

AI summary
A reed includes: a reed main body having a plate shape, the reed main body including a fixed part fixed to a mouthpiece, and a vibrating part that extends from the fixed part and vibrates; and a sensor part that is disposed inside the vibrating part or on an inner surface of the vibrating part, the inner surface of the vibrating part facing the mouthpiece, the sensor part comprising an effective sensor portion that detects vibration of the vibrating part.
