Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle event recorder systems require vehicles to return to a specific location for data download, limiting continuous communication and data availability over large areas, and are not optimized for real-time high-resolution video transmission due to bandwidth constraints.
Innovation Solution
A vehicle event recorder system integrated with cellular wireless communication links, including video cameras, microprocessors, and mobile wireless transceivers, that captures and processes data in real-time, forming a reduced dataset for immediate transmission over limited bandwidth networks while preserving complete datasets for later transmission, maintaining continuous connectivity through a network of distributed cellular base stations.

Engineering Contradiction Analysis
1Loss of information
If vehicles return to a specific location for data download, then data can be downloaded, but continuous communication and data availability over large areas is limited
Solution Approach 1:
The patent segments the data into two types: complete datasets stored locally in the vehicle and reduced datasets transmitted to the server. This segmentation allows the system to maintain continuous communication by sending only essential reduced data, while complete data remains available locally without requiring vehicle return to a specific location.
Solution Approach 2:
The patent introduces a new dimension of data representation by creating reduced datasets that are transmitted over the communication network. This dimensional transformation of data from complete to reduced form enables continuous communication capabilities while maintaining data availability through the dual-storage approach.
2Speed
If high-resolution video is transmitted in real-time, then real-time monitoring is achieved, but bandwidth constraints prevent effective transmission
Solution Approach 1:
The patent extracts only the essential information from complete video datasets to create reduced datasets for transmission. By taking out only the critical data elements needed for monitoring purposes, the system achieves real-time transmission capabilities within bandwidth constraints while maintaining the ability to retrieve complete high-resolution data when needed.
Solution Approach 2:
The patent changes the parameters of the data by transforming complete high-resolution video datasets into reduced datasets with modified data characteristics. This parameter transformation reduces the data quantity suitable for bandwidth-constrained transmission while preserving the ability to access complete data locally, enabling real-time monitoring within bandwidth limits.
3Loss of information
If complete datasets are transmitted, then full data availability is achieved, but transmission time and bandwidth consumption increase
Solution Approach 1:
The patent performs preliminary action by pre-storing complete datasets locally in the vehicle before any transmission is needed. This preliminary local storage ensures data completeness is already achieved in the vehicle, eliminating the need for time-consuming transmission of complete datasets and allowing rapid access to full data when required.
Solution Approach 2:
The patent applies partial action by transmitting only reduced datasets that contain essential information, rather than transmitting complete datasets. This partial transmission approach reduces transmission time and bandwidth consumption significantly while maintaining data completeness locally for when full data is needed.
