Solution Overview

Problem

Existing musical sound signal generating devices are not capable of generating interesting sounds while maintaining the features of the original signal, as they are limited in varying sound elements like length, pitch, and formants.

Innovation Solution

A content data generating device and sound signal generating device that cut out segments from waveform data and crossfade them, allowing for flexible manipulation of segment lengths, reading rates, and connection of tracks in series or feedback, enabling the generation of interesting musical sounds with varied features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the musical sound signal generating device changes only one element (sound length, pitch, or formants) while maintaining the features of the original signal, then the original signal's features are preserved, but the ability to generate interesting musical sounds is limited

Engineering Contradiction:

Improvepreservation of original signal featuresVSAvoidability to generate interesting musical sounds

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The device dynamically adjusts multiple parameters (segment length, reading rate, crossfading length) simultaneously rather than fixing them, allowing the system to adapt between preserving original features and creating interesting variations based on operational needs

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The invention changes multiple parameters at once (segment length, reading rate, crossfading length) rather than modifying single parameters in isolation, enabling both preservation of original characteristics and generation of interesting musical variations through coordinated parameter adjustments

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the device processes the original signal to generate interesting musical sounds, then the ability to create varied sounds is improved, but the features of the original signal are lost

Engineering Contradiction:

Improveability to generate interesting musical soundsVSAvoidpreservation of original signal features

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The device applies partial transformation by processing only certain aspects of the original signal (through selective segmenting and crossfading) rather than completely transforming it, thus generating interesting sounds while retaining some original features

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

Through coordinated changes in segment length, reading rate, and crossfading length, the system achieves interesting sound variations while maintaining connection to the original signal's characteristics

Inventive Principle:

Principle #35Parameter changes

3Reliability

If the segment length is synchronized with the cycle of the original signal, then the original signal's features are maintained, but the flexibility in sound manipulation is reduced

Engineering Contradiction:

Improvemaintenance of original signal featuresVSAvoidflexibility in sound manipulation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The segment length is made dynamic rather than fixed to the original signal's cycle, allowing it to be adjusted independently while other parameters compensate to maintain desired signal characteristics

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The original signal is divided into segments that can be manipulated independently with flexible lengths, allowing both feature preservation and manipulation flexibility through the crossfading mechanism

Inventive Principle:

Principle #1Segmentation
