Collision-Activated Information Exchange Device for Vehicular Accidents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not effectively address the emotional and informational needs of victims and their loved ones in the aftermath of vehicular collisions, particularly in hit-and-run accidents, as they often lack mechanisms for automatic exchange of collision-related information.
Innovation Solution
A collision-activated information exchange device (CIED) that uses an impact sensor to detect collisions and transmit real-time information via wireless communication, including vehicle identification, GPS data, and collision parameters, to other involved vehicles or approved devices for later retrieval or analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If automatic collision information exchange system is implemented, then information exchange speed and completeness is improved, but device complexity and cost increase
Solution Approach 1:
The system is divided into independent functional modules: impact sensors detect collisions, wireless communication radios transmit data, processors manage information exchange, and memory devices store records. Each module operates independently but coordinates through standardized protocols, enabling rapid automated information exchange without requiring a monolithic complex system.
Solution Approach 2:
The collision information exchange device integrates multiple functions into a single system: collision detection, data logging, wireless communication, and automatic information transmission. This multi-functional approach reduces overall system complexity compared to having separate systems for each function while maintaining rapid information exchange capabilities.
2Loss of information
If real-time collision data logging is implemented, then evidence quality and completeness is improved, but energy consumption and device complexity increase
Solution Approach 1:
The system pre-logs essential vehicle identification information, GPS coordinates, and sensor data into memory devices before collisions occur. When a collision is detected, the pre-configured system immediately transmits this pre-captured data without requiring active sensing or processing during the critical post-collision period, thereby maintaining information completeness while minimizing energy consumption.
Solution Approach 2:
The system uses cost-effective, low-power memory devices and sensors that capture and store collision data temporarily. These components are designed for single-use or limited-duration operation focused specifically on the collision event, providing complete information logging at minimal energy cost without requiring continuous high-power operation.
3Reliability
If wireless communication radio is continuously active, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The wireless communication radio operates in a low-power state during normal conditions and activates periodically or event-triggered when collisions are detected. This periodic activation ensures the system maintains communication capability when needed while consuming minimal energy during extended periods without incidents, achieving a balance between reliability and energy efficiency.

AI summary
A method, a system, and an apparatus used to automatically exchange identification and collision-related information utilizing wireless communication devices during vehicular accidents are presented. Upon collision, an impact sensor detects and registers the crash, causing a processor to trigger a collision warning, record selected identification and collision-related information in an electronic file, and exchange the same through a secure wireless connection with a collision-activated information exchange device (CIED) of the other vehicle involved and/or with an information exchange device (IED) or devices in the area of the collision. The stored electronic files can later be accessed by and/or even transmitted to authorities to serve as evidence in hit-and-run investigation and/or accident reconstruction.
