Vehicle Data Off-boarding for Storage Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle groups face challenges in managing large volumes of data captured on the move, particularly in terms of storage capacity and data quality, as existing systems often store all data without differentiation, leading to inefficiencies and potential degradation due to ambient conditions.
Innovation Solution
A method and system for selectively off-boarding data sets from a lead vehicle to a remote vehicle or remote storage based on evaluated quality parameters, such as file size and frame variation, ensuring that only high-quality data is redundantly stored across multiple locations, thereby optimizing storage capacity and protecting against data degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If all captured data is stored without differentiation, then storage capacity is fully utilized, but storage efficiency deteriorates due to filling space with low-quality data
Solution Approach 1:
The patent applies local quality by differentiating storage actions based on data quality characteristics. High-quality data (exceeding thresholds in file size, frame variation, or other parameters) is selectively off-boarded to remote storage, while lower-quality data remains on the vehicle's local storage. This ensures that storage capacity is optimally utilized with effectual data rather than uniformly treating all data equally.
2Quantity of substance
If data is off-boarded to remote storage, then storage capacity issues are reduced, but system complexity increases due to additional transmission and evaluation mechanisms
Solution Approach 1:
The patent implements preliminary action by evaluating data quality parameters (file size, frame variation, etc.) immediately after data capture, before the data is fully processed or transmitted. This preliminary quality assessment enables the system to make advance decisions about off-boarding high-quality data, simplifying the overall workflow by preventing low-quality data from consuming remote storage resources in the first place.
Solution Approach 2:
The system creates copies of high-quality data sets and transmits them to remote storage devices. Rather than moving the original data, the patent generates and stores copies, allowing the vehicle to retain local access to the original data while off-loading redundant high-quality copies to remote locations, thereby managing storage capacity without complete data migration.
3Productivity
If only high-quality data is stored, then storage efficiency is improved, but data loss increases when low-quality data is discarded
Solution Approach 1:
The patent employs parameter changes by dynamically adjusting quality thresholds based on various factors such as available storage capacity, data type, mission requirements, and environmental conditions. These parameters (file size thresholds, frame variation limits, bit rate requirements) can be modified in real-time to balance storage efficiency with information retention, ensuring that data loss is minimized while maintaining high storage efficiency through adaptive quality filtering.
4Ease of operation
If data is transmitted to remote storage during vehicle operation, then real-time data management is achieved, but energy consumption increases due to continuous communication
Solution Approach 1:
The patent implements periodic action by transmitting data at scheduled intervals or based on accumulated data thresholds rather than continuously. High-quality data sets are identified and transmitted periodically when communication opportunities arise, rather than maintaining constant communication links. This reduces energy consumption while still achieving real-time data management capabilities through regular updates and selective off-boarding.
