Solution Overview

Problem

Existing systems for enhancing traffic safety and convenience, particularly for vulnerable road users, face challenges in accurately predicting the movement and intentions of pedestrians to effectively warn approaching vehicles.

Innovation Solution

The proposed system employs in-vehicle information processing devices equipped with sensors and image-capturing technology to analyze pedestrian movements and predict their future locations. This information is then used to determine if a warning should be issued to the vehicle's occupants or transmitted to other vehicles in the vicinity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system issues warnings based on detected pedestrian movements, then traffic safety is improved, but false warnings may be issued due to inaccurate prediction of pedestrian intentions

Engineering Contradiction:
Improveaccuracy of pedestrian movement predictionVSAvoidinability to accurately predict pedestrian future location
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system performs preliminary actions by detecting current pedestrian movement and pre-calculating potential future locations before actual collision risk occurs. This allows the system to issue warnings in advance while maintaining accuracy through continuous movement detection and prediction algorithms.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system applies dynamics by continuously updating pedestrian movement detection and prediction based on real-time changes in pedestrian behavior. The prediction model adapts to dynamic pedestrian intentions rather than relying on static assumptions, improving both reliability and reducing false warnings.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If the system continuously monitors and predicts pedestrian movements, then warning accuracy is improved, but computational load and system complexity increase

Engineering Contradiction:
Improveprecision of pedestrian location predictionVSAvoidcomplexity of movement analysis system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the complex task of pedestrian prediction into distinct functional modules: movement detection, intention prediction, and warning decision-making. This modular approach maintains high prediction precision while managing system complexity through organized, independent processing stages.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the system issues warnings for all detected hazardous situations, then safety coverage is improved, but unnecessary warnings may cause driver distraction or alarm fatigue

Engineering Contradiction:
Improvesafety coverageVSAvoiddriver response to warnings
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system uses feedback mechanisms to evaluate the effectiveness of issued warnings and adjust future warning behavior. By monitoring driver responses and actual collision outcomes, the system refines its warning criteria to maintain comprehensive safety coverage while reducing unnecessary alerts that cause distraction or alarm fatigue.

Inventive Principle:
Principle #23Feedback
