Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traffic accident warning systems use only past and current object locations, then the system is simple to implement, but it generates frequent false alarms and reduces reliability
Solution Approach 1:
The system performs preliminary trajectory prediction by analyzing future potential paths of pedestrians and vehicles before accidents occur. This proactive approach allows the system to anticipate dangerous situations and generate warnings in advance, reducing false alarms by predicting actual collision risks rather than reacting to past positions alone
Solution Approach 2:
The system incorporates feedback mechanisms by continuously monitoring video feeds, comparing predicted trajectories with actual movements, and adjusting warning generation based on real-time observations. This feedback loop enables the system to learn from past predictions and improve accuracy, reducing false alarms while maintaining high reliability
2Device complexity
If pedestrian behavior prediction uses only image data, then the system is simpler, but prediction accuracy is insufficient
Solution Approach 1:
The system merges multiple data sources including image data, video sequences, and trajectory predictions into a unified prediction framework. By combining visual information from cameras with motion trajectory analysis, the system achieves higher prediction accuracy while managing complexity through integrated processing
