Solution Overview

Problem

Existing vehicle information processing systems fail to effectively integrate internal and external information related to the same target from different sources, leading to increased processing load and potential delays in risk prediction and control.

Innovation Solution

A vehicle device equipped with an acquisition unit for internal information, a comparison unit for external information, and an integration unit that determines and integrates information from various sources based on the identical target, reducing redundant processing and enhancing information sharing and risk prediction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If information from multiple sources is processed separately, then each source can be processed independently, but processing load increases and delays occur

Engineering Contradiction:

Improveinformation processing efficiencyVSAvoidprocessing load

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges internal information from the subject vehicle's sensors with external information from other vehicles' sensors by identifying identical targets and integrating their data. This combining approach reduces processing load by eliminating redundant operations and improves efficiency by leveraging multiple data sources simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If internal and external information are not integrated, then processing remains simple, but risk prediction accuracy decreases

Engineering Contradiction:

Improverisk prediction accuracyVSAvoidinformation integration complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the information integration process into distinct steps: acquiring internal information, acquiring external information, comparing target identifiers, and integrating matching information. This segmentation makes the complex integration task manageable and systematic, improving reliability while controlling complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses target identifiers as an intermediary mechanism to link internal and external information. By comparing identifiers from both sources, the system mediates between different information streams to find matches, enabling accurate risk prediction without direct complex integration of all data.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Quantity of substance

If redundant information processing is performed, then comprehensive coverage is achieved, but processing time increases

Engineering Contradiction:

Improveinformation coverageVSAvoidprocessing time

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The patent extracts and processes only the essential information needed for risk prediction by identifying identical targets through their identifiers. This extraction approach maintains comprehensive coverage of relevant targets while eliminating redundant processing of duplicate or non-matching information, reducing processing time.

Inventive Principle:

Principle #2Taking out (Extraction)
