Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If on-board sensors are used to detect surrounding environment, then detection accuracy is improved, but detection range is limited causing potential risks to be missed
Solution Approach 1:
The patent introduces a coordination support device as an intermediary that receives detection results from multiple on-board sensors and performs integrated analysis. This mediator extends the effective detection range by combining data from multiple sources while maintaining the high accuracy of individual sensors, thus resolving the contradiction between limited detection range and detection accuracy.
Solution Approach 2:
The patent merges detection results from multiple on-board sensors (camera, radar, etc.) to create a comprehensive view of the surrounding environment. By combining the detection ranges of multiple sensors and performing integrated analysis, the system achieves both extended detection range and maintained detection accuracy.
2Reliability
If alarm is issued after potential risk becomes apparent, then false alarms are reduced, but response time is insufficient for avoiding risks
Solution Approach 1:
The patent performs preliminary analysis of detection results to identify potential risks before they become apparent dangers. The coordination support device analyzes sensor data in advance, predicts potential collision risks, and prepares alarm notifications ahead of time, ensuring both high alarm accuracy and sufficient response time for risk avoidance.
Solution Approach 2:
The system implements continuous feedback by constantly monitoring detection results and adjusting risk assessment in real-time. This feedback mechanism allows the system to maintain high alarm accuracy while providing timely warnings, as the alarm issuance timing is dynamically adjusted based on the evolving risk situation.
3Reliability
If multiple traffic participants are monitored, then overall safety is improved, but system complexity increases
Solution Approach 1:
The patent segments the monitoring task by assigning specific detection and analysis functions to individual on-board sensors (camera for visual detection, radar for distance measurement, etc.). The coordination support device then integrates these segmented detection results, managing multiple traffic participants through modular processing that improves overall safety while controlling system complexity.
