Solution Overview

Problem

Existing augmented reality navigation systems for vehicles lack accuracy and diversity in information display, particularly in environments without precise maps or positioning, leading to incorrect display positions and reduced usability.

Innovation Solution

An information display apparatus using a processor to determine the position of display objects based on the number of lanes, lane directions, and driving directions, allowing for accurate augmented reality displays within vehicles or external devices, and providing eco-state and regional boundary information through augmented reality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If augmented reality navigation systems are used in environments without precise maps or positioning, then the system can operate in more locations, but the display position accuracy deteriorates

Engineering Contradiction:
Improveoperability in environments without precise mapsVSAvoiddisplay position accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent introduces an intermediary calculation process that uses the number of lanes and driving direction as intermediate parameters to bridge the gap between general map data and precise display positioning. By calculating the host vehicle's driving direction and determining lane information, the system can accurately position display objects even without precise map data, thus resolving the contradiction between adaptability and measurement precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the number of lanes and driving direction information are used to determine display object positions, then display position accuracy is improved, but the computational complexity increases

Engineering Contradiction:
Improvedisplay position accuracyVSAvoidcomputational complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the positioning problem into distinct modules: obtaining driving direction information, determining lane information based on the number of lanes, calculating display object positions for each lane, and rendering. This segmentation allows the system to handle complex computations in a structured manner, improving display position accuracy while managing computational complexity through modular processing.

Inventive Principle:
Principle #1Segmentation

3Loss of information

If augmented reality displays provide detailed vehicle information, then information diversity is improved, but the ease of operation deteriorates due to information overload

Engineering Contradiction:
Improveinformation diversityVSAvoiduser convenience
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent applies local quality by providing different types of information (fuel efficiency, battery charge, motor temperature) at specific display locations corresponding to their relevant contexts. For example, fuel efficiency information is displayed in relation to lane information, battery charge near the vehicle icon, and motor temperature in the augmented reality overlay. This localized information presentation improves information diversity while maintaining ease of operation by preventing information overload through contextual organization.

Inventive Principle:
Principle #3Local quality
