Solution Overview
Problem
Current systems for detecting vehicle crashes using sensors and apps are inefficient, as they often rely on limited sensor data and lack accurate methods for generating comprehensive crash data, which can lead to false alarms and incomplete information.
Innovation Solution
A computer-implemented method and system that utilizes multiple sensors on mobile computing devices within a vehicle to receive and generate combined sensor data before and after a crash, including accelerometer, gyroscope, pressure, and sound monitoring data, to accurately determine crash occurrence and severity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are used to collect comprehensive crash data, then crash detection accuracy is improved, but device complexity increases
Solution Approach 1:
The mobile computing device performs multiple functions: it collects sensor data, detects crashes, generates combined sensor data, and transmits information to insurance providers. By making the mobile device universal and multi-functional, the system achieves comprehensive crash data collection without adding separate dedicated hardware components, thus improving accuracy while managing complexity.
Solution Approach 2:
The patent combines sensor data from before and after the crash into a single combined sensor data structure. This merging of data collection periods and multiple sensor inputs into one unified dataset improves measurement precision while simplifying the overall data handling process rather than requiring separate systems for each function.
2Measurement precision
If sensor data is collected for extended periods before and after crash, then severity assessment is improved, but loss of time increases
Solution Approach 1:
The system continuously collects sensor data before a crash occurs and stores it in buffer memory. This preliminary action ensures that when a crash happens, the data is already captured and ready for immediate processing. The combined sensor data includes pre-crash, crash, and post-crash information without requiring extended real-time collection during the critical response period.
3Reliability
If comprehensive sensor data is generated and transmitted, then insurance claim processing is improved, but productivity decreases
Solution Approach 1:
The mobile computing device automatically performs crash detection, generates combined sensor data, and transmits it to the insurance provider without requiring manual intervention. This self-service capability ensures comprehensive data is captured and submitted reliably while maintaining efficiency, as the automated process eliminates delays associated with manual data collection and submission.
