Solution Overview

Problem

Existing actuation apparatuses that respond to sound do not change motion patterns when the rhythm of detected sounds remains constant, leading to monotonous actions that can cause user boredom.

Innovation Solution

An apparatus control device that determines the characteristic of a performance sound and reflects the situation of the apparatus or its surroundings in coordinated actions executed in sync with the performance sound.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the apparatus executes a fixed motion pattern in response to detected sound, then the control logic is simple, but the actions become monotonous and cause user boredom

Engineering Contradiction:

Improvecontrol logic complexityVSAvoidmotion pattern variety

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the motion pattern selectable and changeable based on detected situation. The apparatus transitions from a fixed motion pattern to multiple selectable motion patterns (first, second, and third motion patterns) that can be dynamically chosen based on situation detection, thereby increasing adaptability without significantly complicating the control logic.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of motion pattern selection based on the detected situation. When the situation detection unit detects a specific situation, the control unit selects a different motion pattern from available patterns, effectively using parameter changes (situation-based selection) to diversify actions and prevent user boredom.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the apparatus changes motion patterns frequently, then user engagement increases, but the device complexity increases

Engineering Contradiction:

Improvemotion pattern varietyVSAvoidcontrol logic complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamics through situation-based motion pattern selection. Rather than frequently changing patterns arbitrarily, the system dynamically selects from multiple motion patterns based on detected situations, achieving user engagement through context-appropriate variations while keeping control logic manageable through situation-based decision-making.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent uses feedback from the situation detection unit to inform motion pattern selection. The control unit receives situation information and selects motion patterns accordingly, creating a feedback loop that enables adaptive behavior without requiring complex control logic, as the situation detection provides the necessary input for pattern selection.

Inventive Principle:

Principle #23Feedback

AI summary

An apparatus control device for controlling an apparatus includes at least one processor configured to determine a characteristic of performance sound around a robot that is the apparatus, determine a situation of the robot or a situation around the robot, and when causing the robot to execute a performance coordinated action that is coordinated with the performance sound based on the determined characteristic of the performance sound, reflect the determined situation to the performance coordinated action.
