Cymbal Motion Reproduction via Transparent Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack the capability to effectively reproduce the motion of the vibration portion of percussion instruments during a performance, specifically the motion of a cymbal when struck by a stick, which is aesthetically appealing.
Innovation Solution
A percussion instrument motion reproduction device comprising a cymbal with a first driving portion that visually displaces the cymbal in response to an electrical signal, and second driving portions that vibrate the cymbal to emit sound, replicating the motion and sound of a normal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a stick is used to strike a drum in automatic performance, then the motion of the stick can be reproduced, but the motion of the vibration portion (cymbal surface) cannot be reproduced
Solution Approach 1:
The patent uses a transparent plate that visually copies the motion of the vibration portion of the percussion instrument. The plate is displaced to match the motion trajectory of the cymbal surface during striking, creating a visual representation of the otherwise invisible vibration motion. This allows the motion of the vibration portion to be reproduced visually without requiring direct measurement or complex sensors on the instrument itself.
Solution Approach 2:
The patent introduces a transparent plate as an intermediary element between the vibration portion and the viewer. The plate is driven by a driving portion that converts the vibration motion into visual displacement, serving as a mediator that makes the invisible vibration motion visible while not interfering with the actual instrument performance.
2Illumination intensity
If the vibration portion is visually displaced to reproduce motion, then visual appeal is enhanced, but the actual vibration and sound production may be affected
Solution Approach 1:
The patent employs a transparent plate that can be visually displaced without significantly affecting the acoustic properties of the instrument. The plate is designed to be thin and transparent, allowing it to move visually to reproduce the vibration motion while minimizing interference with the actual vibration and sound production of the cymbal.
Solution Approach 2:
The transparent plate serves as an intermediary that separates the visual reproduction function from the acoustic production function. By placing the plate in a position where it can visually track the vibration motion without physically interfering with the cymbal's vibration, the system maintains both visual enhancement and acoustic authenticity.
