Solution Overview

Problem

Current display systems for vehicles do not effectively integrate rearward view monitoring with passenger compartment imaging and speech detection to selectively display relevant regions or features, limiting their functionality and user interaction.

Innovation Solution

A display system comprising imagers and a controller that captures and processes image and audio data to selectively display a passenger's facial region or objects of interest based on detected speech or motion, allowing for hands-free operation and flexible display of rearward and interior views.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the display system continuously displays the entire passenger compartment, then comprehensive monitoring is improved, but information relevance deteriorates due to displaying unnecessary regions

Engineering Contradiction:
Improvemonitoring comprehensivenessVSAvoidinformation relevance
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system extracts and displays only the relevant region of interest within the passenger compartment based on speech detection, rather than displaying the entire compartment. The controller identifies the source of detected speech and selectively displays only that specific area, filtering out unnecessary visual information while maintaining monitoring effectiveness.

Inventive Principle:
Principle #2Taking out (Extraction)

2Measurement precision

If the display system uses multiple sensors and processing units to detect speech and select regions, then display accuracy is improved, but device complexity increases

Engineering Contradiction:
Improveregion selection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The display system is designed to perform multiple functions using integrated components: the imager captures both interior and exterior views, the microphone array detects speech from multiple directions, and the controller processes both visual and audio data to selectively display relevant regions. This multi-functional design improves accuracy without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The controller acts as an intermediary that processes audio signals from the microphone array, identifies speech sources, and uses this information to selectively control the display of specific regions from the imager data. This intermediary processing layer coordinates the multiple sensors and enables accurate region selection while managing system complexity through centralized control.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the display system processes audio signals to detect speech sources, then user interaction capability is improved, but processing time increases

Engineering Contradiction:
Improveinteraction capabilityVSAvoidprocessing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system continuously monitors audio signals from the microphone array in real-time, maintaining readiness to detect speech sources without requiring full processing only when speech occurs. This preliminary monitoring approach enables quick response to user interactions while minimizing unnecessary processing time during non-interactive periods.

Inventive Principle:
Principle #10Preliminary action
