Solution Overview

Problem

Current systems lack an effective method to determine primary responsibility in traffic accidents between mobilities based on error monitoring, which is crucial for identifying the cause and assigning blame accurately.

Innovation Solution

A traffic accident analysis system that includes an error monitoring apparatus and a traffic control server, which detect and analyze event-related potentials (ERPs) such as error-related negativity (ERN) and error positivity (Pe) to determine if a traffic accident occurred and assign responsibility by comparing ERP amplitudes between involved mobilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If event-related potentials (ERPs) are collected and analyzed to determine traffic accident responsibility, then measurement precision of driver error is improved, but device complexity increases due to requiring sensing units, analyzers, and multiple mobility systems

Engineering Contradiction:
Improveresponsibility determination accuracyVSAvoidsystem structure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system divides the responsibility determination process into distinct functional modules: sensing units for ERP collection, analyzers for ERP analysis, detecting units for accident determination, and transmitters for data communication. Each module performs a specific function, allowing the complex system to be managed through modular components that can be independently optimized and maintained.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The traffic control server acts as an intermediary that receives ERP data from multiple mobilities, performs centralized analysis, and determines responsibility. This intermediary approach allows complex ERP analysis to be performed in a centralized location rather than requiring each mobility to have full analytical capabilities, reducing on-vehicle system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If ERP data is collected and analyzed in real-time to determine traffic accident responsibility, then productivity of accident investigation is improved, but loss of time increases due to ERP collection and analysis duration

Engineering Contradiction:
Improveaccident investigation efficiencyVSAvoidERP collection and analysis time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

ERP data is collected and stored in real-time during normal driving operations before any accident occurs. When a traffic accident happens, the pre-collected ERP data can be immediately retrieved and analyzed without waiting for data collection, significantly reducing the time required for post-accident responsibility determination while maintaining high investigation efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system replaces traditional mechanical accident investigation methods (scene reconstruction, witness interviews, physical evidence analysis) with neurophysiological ERP signal analysis. This substitution enables automatic, objective responsibility determination based on neural responses, eliminating the time-consuming manual investigation processes and providing immediate accountability assessment.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
