Solution Overview

Problem

Existing electronic drum systems struggle to generate realistic sound variations for repeated strikes on the same drum pad, leading to a lack of natural imperfection and authenticity in the sound reproduction.

Innovation Solution

The system generates a graphical representation of strike velocity on an electronic drum pad, allowing for the playback of multiple audio files with slight variations to replicate the nuances of human-acoustic instrument performance, even for identical strikes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electronic drum system plays back the same audio file for repeated strikes, then the sound output is consistent and controlled, but the realism and natural imperfection of human performance is lost

Engineering Contradiction:

Improvesound consistencyVSAvoidrealism of sound reproduction

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The system dynamically selects different audio files based on strike characteristics such as velocity, position, and angle. Instead of playing the same static audio file for every strike, the system varies the playback content to reflect the nuances of each individual strike, thereby achieving both consistency in response and realism in sound reproduction.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes multiple parameters including strike velocity, strike position on the drum pad, strike angle, and selected audio file variations. By monitoring these parameters and selecting appropriate audio files from a set of slightly different recordings, the system reproduces the natural imperfections of human drumming while maintaining reliable sound output.

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If the system uses multiple audio files with variations, then the realism and natural imperfection are improved, but the system complexity increases

Engineering Contradiction:

Improverealism of sound reproductionVSAvoidsystem structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The audio library is segmented into multiple individual audio files, each representing a slightly different recording of the same drum sound. The system divides the audio content into manageable segments that can be selectively played based on strike characteristics, allowing for realistic variation without requiring a completely complex system architecture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The electronic drum module is designed to handle multiple functions: it detects strike characteristics (velocity, position, angle), selects appropriate audio files from a library, and plays back the selected sound. This multi-functional design consolidates the complexity into a single device that can manage the entire process of generating realistic drum sounds with natural imperfections.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If the system analyzes strike velocity and selects different audio files, then the authenticity of human performance is replicated, but the processing time and complexity increase

Engineering Contradiction:

Improveauthenticity of performanceVSAvoidsignal processing time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The system pre-organizes multiple audio files in a library before performance, categorizing them by strike characteristics such as velocity ranges, positions, and angles. This preliminary organization allows for rapid selection during performance without requiring complex real-time analysis, thereby reducing processing time while maintaining authenticity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system replaces complex mechanical analysis of strike characteristics with electronic sensing and digital signal processing. Electromechanical transducers convert physical strike parameters into electrical signals that can be quickly processed and used to select appropriate audio files, significantly reducing the time required compared to mechanical measurement methods.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A method of displaying drum-strike velocity information is provided. The method includes receiving trigger data. The trigger data includes a strike velocity of a drum-pad zone on a drum pad. The method includes displaying an image of a drum associated with the drum pad on a display, displaying a first portion of the drum in a first color, and changing the first portion of the drum to a second color. The second color is determined by a magnitude of the strike velocity.
