Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real and virtual sounds are combined to create mixed reality audio, then immersion and reality sense are improved, but system complexity increases

Engineering Contradiction:

Improveimmersion and reality senseVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system segments audio processing into distinct modules: real sound acquisition through microphones, virtual sound generation from audio data, spatial position calculation for multiple sound sources, and combined sound output. This modular segmentation manages complexity while achieving immersive mixed reality audio effects.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The processor acts as an intermediary that receives both real sound signals and virtual sound signals, calculates their spatial positions, and combines them into a unified mixed reality audio output. This intermediary processing layer integrates multiple audio sources while managing system complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If 3D sound conversion is applied to 2D sound, then immersion is improved, but processing time and complexity increase

Engineering Contradiction:

ImproveimmersionVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary spatial position calculations for multiple sound sources based on audio data before combining them with real sounds. By pre-calculating positions and preparing virtual sound fields in advance, the system reduces real-time processing time while maintaining high immersion quality.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If multiple sound sources are processed and combined, then audio realism is improved, but computational load increases

Engineering Contradiction:

Improveaudio realismVSAvoidcomputational load

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system applies different processing qualities to different sound sources based on their spatial positions and importance. Sounds are processed with appropriate levels of detail according to their location in the mixed reality environment, optimizing computational load while maintaining audio realism where most needed.

Inventive Principle:

Principle #3Local quality
