Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional puppets can only perform fixed actions in sync with pre-recorded music, limiting their entertainment value as they cannot generate action feedback in response to external, unknown audio.

Innovation Solution

An electronic device with an audio reception circuit and processing circuit that analyzes external audio data to generate action control signals for movable components, enabling improvisational performances matching the music's characteristics, such as volume and pitch changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pre-recorded music is stored and pre-determined control signals are used, then the puppet can perform synchronized actions with music, but the entertainment experience is limited due to fixed performance only

Engineering Contradiction:

Improvesynchronization reliabilityVSAvoidperformance adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system analyzes audio features in real-time and uses this feedback to dynamically adjust puppet actions. The processing circuit continuously monitors audio data, extracts features like beat and volume, and adjusts control signals accordingly, creating a closed-loop system that adapts performance to match the music characteristics

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent transitions from static pre-programmed actions to dynamic real-time adjustments. The puppet's actions are no longer fixed but continuously adapted based on real-time audio analysis, allowing the performance to evolve with the music's tempo, volume, and rhythm changes

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If real-time audio analysis is implemented, then the device can generate dynamic action feedback for any audio, but the device complexity increases

Engineering Contradiction:

Improveaudio response versatilityVSAvoidprocessing circuit complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system extracts only the essential audio features needed for control, such as beat detection and volume levels, rather than processing the entire audio signal. This selective extraction simplifies the processing requirements while maintaining the ability to generate appropriate actions

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The processing circuit is designed to handle multiple audio types and genres universally by analyzing fundamental audio features rather than requiring specific programming for each music style. This multi-functional approach reduces complexity by using a single analysis framework for diverse audio inputs

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An electronic device includes an audio reception circuit, a processing circuit and at least one movable component. The audio reception circuit receives an audio data. The processing circuit performs an audio feature analysis on the audio data to obtain audio feature data, and determines a corresponding action event according to audio feature data to generate an action control signal corresponding to the action event. The movable component performs the action event in response to the action control signal.
