Solution Overview

Problem

Electronic HiHat cymbals in prior art lack a natural striking sensation due to fixed bottom cymbal pads and friction between elastic materials, which prevents smooth gliding contact similar to acoustic HiHat cymbals.

Innovation Solution

An electronic percussion instrument design where both cymbal pads are free to swing on a shared shaft, with a sliding member promoting smooth contact and sensors for accurate striking detection, mimicking the motion and feel of acoustic HiHat cymbals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the bottom cymbal pad is fixed to the stand, then the structure is simple and stable, but the striking sensation becomes unnatural and the gliding contact is not smooth

Engineering Contradiction:
Improvestriking sensationVSAvoidcymbal pad structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The bottom cymbal pad is changed from a fixed structure to a swingable structure that can pivot on a shaft. This dynamic configuration allows the bottom pad to move in response to strikes on the top pad, creating natural gliding contact and authentic striking sensation similar to acoustic HiHat cymbals.

Inventive Principle:
Principle #15Dynamics

2Reliability

If elastic material is used for the striking surface area, then damping is improved, but friction increases and prevents smooth gliding contact

Engineering Contradiction:
Improvedamping performanceVSAvoidgliding smoothness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cymbal pad is designed with different materials for different functional areas. The striking surface area uses elastic material for damping, while the edge area that contacts the opposing pad uses low-friction material to enable smooth gliding contact. This local differentiation resolves the contradiction between damping and smooth contact.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The cymbal pad employs composite construction with elastic material in the striking surface and low-friction material in the contact edge. This composite approach combines the advantages of both materials: damping from the elastic portion and smooth gliding from the low-friction portion.

Inventive Principle:
Principle #40Composite materials

3Reliability

If both cymbal pads are made of elastic material, then damping is enhanced, but friction between the pads increases and makes the striking sensation unnatural

Engineering Contradiction:
ImprovedampingVSAvoidfriction
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

Different regions of the cymbal pads use different materials optimized for their specific functions. The striking surfaces use elastic material for damping, while the opposing edge areas use low-friction material to minimize contact resistance and enable natural gliding motion.

Inventive Principle:
Principle #3Local quality

4Ease of operation

If the bottom cymbal pad cannot swing, then the structure is simpler, but it is impossible to replicate the performance sensation of acoustic HiHat cymbals

Engineering Contradiction:
Improveperformance sensationVSAvoidcymbal pad mounting
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The bottom cymbal pad is mounted on a shaft that allows it to pivot and swing freely. This dynamic mounting enables the bottom pad to move in response to strikes, replicating the natural behavior of acoustic HiHat cymbals and providing authentic performance sensation.

Inventive Principle:
Principle #15Dynamics

AI summary

An electronic percussion instrument that allows for a performance sensation that is similar to that of an acoustic HiHat cymbal. A sliding mechanism of a top cymbal pad section and a bottom cymbal pad section of an electronic HiHat cymbal where the top cymbal pad section and the bottom cymbal pad section are both fixed so that they can swing together when the top cymbal pad section is struck. Even when the first cymbal pad is struck and swings coming into contact with the second cymbal pad, the gliding contact between the first pad and the second pad is carried out smoothly and allows for a natural striking sensation comparable to that of an acoustic HiHat cymbal.
