Electronic Cymbal Bell Sensor Segmentation for Peeling Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cymbal bell part sensors face issues with peeling off due to deformation into a conical shape, especially under hits or changes in temperature and humidity.
Innovation Solution
A disk-shaped electronic cymbal with a bell part sensor attached in a circumferential direction, utilizing a sheet-shaped sensor with conductive paste on a PET film, and a cover with a conical projection part to ensure close contact and prevent erroneous detection, while maintaining sensitivity and durability.

Engineering Contradiction Analysis
1Reliability
If a sheet-shaped bell part sensor is deformed into a conical shape and disposed in the bell part, then the sensor can detect hits on the bell part, but the sensor may peel off from the frame or the upper and lower films of the sensor itself may peel off due to hits or changes in temperature and humidity
Solution Approach 1:
The bell part sensor is divided into multiple independent sensor parts along the radial direction of the conical bell part. Each sensor part is separately attached to the frame, avoiding the need to deform a single continuous sheet into a conical shape. This segmentation prevents peeling by eliminating the stress concentration that would occur at the deformation zones of a continuous sheet.
2Ease of manufacture
If a sheet-shaped bell part sensor is deformed into a conical shape, then the sensor can be installed on the bell part, but the installation complexity and potential for peeling increase
Solution Approach 1:
The sensor is segmented into multiple parts that can be independently attached to different sections of the conical bell part. This eliminates the complex deformation process required for a single sheet and simplifies installation, as each segment can be separately positioned and fixed without affecting the others.
Solution Approach 2:
Instead of deforming a two-dimensional sheet into a three-dimensional conical shape (which causes peeling), the solution places multiple one-dimensional sensor parts along the radial direction of the cone. This dimensional approach allows the sensors to conform to the conical surface without requiring sheet deformation, thereby simplifying the installation process.

AI summary
An electronic cymbal and a bell part sensor installation method are provided. The electronic cymbal includes: a disk-shaped frame; a frame bell part which is configured at a center of the frame in a top view; a bell part sensor which is attached onto the frame bell part in a circumferential direction and detects a hit on the frame bell part; and a cover which covers the frame and the bell part sensor and has a surface formed as a hit surface, wherein the bell part sensor is separated in at least a radial direction of the frame bell part.
