Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the capability to timely and accurately provide critical data such as occupant location, acceleration, and state within a vehicle during and after an incident, which is essential for effective emergency response.
Innovation Solution
A system utilizing portable devices with movement sensors and communication mechanisms that allow vehicles to collect and transmit data to remote servers, including user location, acceleration, and state, even when a remote server is inaccessible, ensuring that emergency responders receive vital information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data is transmitted to a remote server during an incident, then data availability for emergency response is improved, but system reliability deteriorates when the remote server is inaccessible
Solution Approach 1:
The portable device stores incident data locally in memory before needing to transmit it. When an incident occurs, the device can immediately access pre-stored data without requiring server connectivity, ensuring data availability even when the remote server is inaccessible.
Solution Approach 2:
The portable device acts as an intermediary between the incident scene and the remote server. It collects and stores data locally, then transmits it to the server when connectivity is available, or provides it directly to emergency responders when the server is inaccessible, bridging the gap between data collection and data delivery.
2Measurement precision
If multiple data parameters are collected during an incident, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The portable device is designed with multi-functionality, integrating multiple sensor types (accelerometer, gyroscope, proximity sensor, camera) into a single device that can perform various measurement functions. This allows comprehensive data collection without requiring separate devices for each parameter, managing complexity through consolidation.
Solution Approach 2:
Multiple sensor functions are merged into the portable device, combining acceleration sensing, rotation sensing, proximity detection, and imaging capabilities in one integrated system. This consolidation enables comprehensive occupant state monitoring while reducing the number of separate components needed.

Data Source
AI summary
A computer is programmed to receive data from one or more vehicle sensors. The computer identifies an incident based on the data. The computer sends a first instruction to a wearable portable device requesting data representing movement of the portable device for a first predetermined time period. The computer receives data from the portable device representing movement of the first portable device for the first predetermined time period.
