Solution Overview

Problem

Existing audio systems in amusement park attractions struggle to maintain a consistent spatial audio experience as guests move within dynamic environments, such as ride vehicles, due to changing distances between listeners and audio output devices.

Innovation Solution

A spatial audio adjustment system that utilizes motion sensors to generate audio control instructions based on measured or simulated motion data, adjusting audio output in real-time to maintain a consistent spatial audio experience by accounting for guest movements relative to audio output devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If audio output devices are fixed in position within a ride vehicle, then the device complexity is reduced, but the spatial audio experience deteriorates as guests move relative to the devices

Engineering Contradiction:
Improveaudio system structureVSAvoidspatial audio experience consistency
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The audio system transitions from a static configuration to a dynamic one by using motion sensors to detect guest movement and dynamically adjusting audio output parameters. The controller modifies audio signals in real-time based on detected motion, allowing the system to adapt to changing spatial relationships between guests and audio devices without requiring physically movable components.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements a feedback loop where motion sensors continuously monitor guest position and movement, transmit this data to the controller, which then adjusts audio output accordingly. This closed-loop control ensures that spatial audio characteristics are maintained despite guest movement, as the system responds to actual conditions rather than relying on pre-programmed positions.

Inventive Principle:
Principle #23Feedback

2Reliability

If audio output devices are moved to track guests, then the spatial audio experience is improved, but the device complexity and mechanical requirements increase

Engineering Contradiction:
Improvespatial audio experience consistencyVSAvoidaudio system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical approach of physically moving audio output devices with an electronic signal processing solution. Instead of mechanically tracking guests with movable speakers, the system uses motion sensors and digital audio processing to simulate the effect of tracking, thereby achieving spatial audio consistency without mechanical complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If real-time motion detection is implemented, then the spatial audio adjustment accuracy is improved, but the use of energy and system complexity increase

Engineering Contradiction:
Improvemotion detection accuracyVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system implements motion detection and audio adjustment selectively rather than continuously at maximum precision. Motion sensors detect significant movements and trigger audio adjustments only when necessary, rather than maintaining constant high-precision tracking. This reduces energy consumption while still providing effective spatial audio adjustment for meaningful guest movements.

Inventive Principle:
Principle #16Partial or excessive action
