Solution Overview

Problem

The utilization of ADAS maps, which include various kinds of new content such as curvature, slope, and speed limit, is still low, limiting their effectiveness in providing differentiated path guidance services.

Innovation Solution

An electronic device and method that stores ADAS map content in units of links, checks for content relevant to the current location, and outputs a UI screen highlighting this content through a display, enhancing path guidance and providing differentiated services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If ADAS map content is stored and processed to provide differentiated path guidance, then service differentiation and user visibility are improved, but device complexity and processing requirements increase

Engineering Contradiction:

Improvepath guidance service differentiationVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ADAS map content is segmented into discrete elements (curvature, slope, speed limit) stored in units of links. The system processes only relevant segments based on current location, dividing the large map data into manageable portions that can be independently evaluated and displayed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system applies local quality by checking ADAS map content only for the current location and predetermined range rather than processing entire map data. The UI screen highlights only locally relevant content (curvature, slope, speed limit at current position) rather than displaying all map information uniformly.

Inventive Principle:

Principle #3Local quality

2Measurement precision

If ADAS map content is continuously monitored and displayed, then real-time guidance accuracy is improved, but energy consumption increases

Engineering Contradiction:

Improvecurrent location detection accuracyVSAvoidenergy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system performs partial action by checking only the predetermined range around the current location rather than continuously monitoring the entire path. This selective processing maintains real-time accuracy for relevant sections while reducing overall computational energy consumption.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system implements periodic checking of ADAS map content at relevant locations along the path rather than continuous monitoring of all data. This periodic evaluation maintains measurement precision at critical points while reducing energy consumption through intermittent processing.

Inventive Principle:

Principle #19Periodic action
