Solution Overview

Problem

Existing animation generation devices fail to maintain integrity between animation movement and sound when animation reproduction is stopped by the user, leading to a sense of incongruity due to continued sound playback.

Innovation Solution

A sound control device that acquires animation and sound data, analyzes sound features to generate attribute information, and calculates stop time sound information to determine a suitable output method for fading out the sound when animation reproduction is stopped, ensuring a natural termination of the sound.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the sound is edited to match the movement of animation before reproduction is started, then the integrity between movement and sound is secured, but when reproduction is stopped during playback, the sound continues to be played which creates a sense of incongruity

Engineering Contradiction:

Improveintegrity between animation movement and soundVSAvoiduser experience when animation is stopped

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the sound output behavior adaptive rather than static. The sound output control section dynamically adjusts the sound playback based on the animation reproduction state - when animation is stopped, the sound automatically fades out or stops accordingly. This dynamic adjustment resolves the contradiction by allowing the sound behavior to change based on operational conditions, maintaining integrity while adapting to user actions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements feedback by having the sound output control section monitor the animation reproduction state and adjust sound playback accordingly. When the animation reproduction is stopped, the system receives feedback about this state change and responds by stopping or fading out the sound, thereby maintaining the integrity between animation and sound throughout the playback process.

Inventive Principle:

Principle #23Feedback

2Ease of manufacture

If the sound continues to be played after animation is stopped, then the sound editing is simple, but the user experiences incongruity between stopped animation and continued sound

Engineering Contradiction:

Improvesound editing simplicityVSAvoidsynchronization between animation and sound

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent applies preliminary action by preparing the sound output control logic in advance to handle animation stop events. The system is pre-configured to monitor animation reproduction state and automatically adjust sound playback when stopping occurs, eliminating the need for complex post-editing while maintaining synchronization integrity.

AI summary

Sound is outputted, without giving the sense of incongruity to the user, even if reproduction of animation is stopped by the user. An animation acquiring section 11 acquires animation data D1 representing an animation generated in advance based on a setting operation by the user, and sound data D2 representing a sound to be reproduced in association with the animation. A sound output control section 12 calculates stop time sound information representing a feature of the sound at a point of time at which reproduction of the animation is stopped, using sound attribute information D4, in response to input of a stop command by the user, and determines a predetermined output method of the sound that matches the animation, based on the calculated stop time sound information, to reproduce the sound by the determined output method.
