Vehicle Data Collection via Backend Request
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for collecting and transmitting vehicle-based data from a swarm of vehicles lack intelligent data handling and efficient management, leading to unnecessary data storage and transmission inefficiencies.
Innovation Solution
Implementing a service-oriented method where vehicles collect and store data locally, allowing the backend computer to request and retrieve only necessary data, with optional deletion after a specified time to maintain storage capacity and optimize workload, using environmental sensors, a data aggregator, and bidirectional/unidirectional communication channels for secure and efficient data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is forwarded directly from the vehicle without intelligent handling, then data transmission is simple, but storage capacity is wasted and transmission efficiency is low
Solution Approach 1:
The patent applies preliminary action by performing data filtering, aggregation, and prioritization in the vehicle before transmission. The onboard system pre-processes sensor data to identify only relevant information for backend processing, eliminating unnecessary data transmission and optimizing storage utilization.
Solution Approach 2:
The vehicle's onboard system autonomously manages data selection and prioritization without requiring constant backend intervention. The system self-determines which data to transmit based on predefined criteria and backend requests, reducing communication overhead and improving transmission efficiency.
2Loss of information
If all collected data is stored and transmitted, then data completeness is high, but storage capacity is consumed and transmission workload increases
Solution Approach 1:
The patent extracts only the essential and relevant data from the complete sensor dataset for transmission to the backend. The onboard system identifies and transmits only high-priority data such as safety-critical information and requested parameters, leaving non-essential data locally stored or discarded.
Solution Approach 2:
The system transmits a partial subset of collected data rather than all data. By selectively transmitting only necessary portions based on backend requests and priority levels, the system avoids unnecessary transmission workload while maintaining data completeness for critical information.
3Loss of information
If data is transmitted continuously, then data availability is high, but transmission energy consumption increases
Solution Approach 1:
The patent implements periodic data transmission based on backend requests and predefined schedules rather than continuous transmission. The onboard system transmits data at specific intervals or when triggered by backend queries, reducing energy consumption while maintaining adequate data availability for backend processing.
Solution Approach 2:
The system autonomously determines transmission timing based on data priority, backend requests, and local storage status. High-priority data is transmitted immediately when available, while lower-priority data waits for appropriate transmission opportunities, optimizing energy usage without compromising critical data availability.
