Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all in-vehicle data is transmitted to the server device, then data availability for multiple applications is improved, but communication traffic and server utilization fees increase
Solution Approach 1:
The patent extracts and processes only the necessary data locally using on-board processors and algorithms, rather than transmitting all raw in-vehicle data to the server. This selective extraction reduces communication traffic while maintaining data availability for multiple applications through local data processing and intelligent transmission decisions.
Solution Approach 2:
The patent segments data processing into multiple levels: local in-vehicle processing, regional edge computing nodes, and central server processing. This segmentation allows data to be processed closer to the source when possible, reducing the need to transmit all data to the central server while still providing comprehensive data availability when needed.
2Adaptability or versatility
If multiple applications independently process and transmit data, then application-specific data processing is improved, but redundant data transmission and server utilization fees increase
Solution Approach 1:
The patent merges data processing and transmission functions through a centralized data management system that coordinates multiple applications. This system consolidates data collection, processing, and transmission decisions, allowing multiple applications to share processed results and transmit only necessary data to the server, thereby reducing redundant transmissions while maintaining application-specific processing capabilities.
Solution Approach 2:
The patent implements a universal data processing platform that serves multiple applications simultaneously. This platform provides common data processing functions, data storage, and transmission management that can be utilized by various applications, eliminating the need for each application to independently process and transmit the same data while still maintaining adaptability to specific application requirements.
3Ease of operation
If data is processed and transmitted by multiple applications independently, then application autonomy is improved, but data utilization efficiency decreases
Solution Approach 1:
The patent introduces a data management intermediary system that coordinates between multiple applications and the server. This intermediary maintains application autonomy by allowing each application to request and receive data independently, while simultaneously optimizing overall data utilization by managing data processing, caching results, and coordinating transmissions to prevent redundancy and improve efficiency.
Data Source
AI summary
By an in-vehicle device mounted on a vehicle or a data synchronization method, primary data is acquired from a control device of the vehicle or an expansion device, the primary data is stored, a first application program is executed, and a second application program is executed to utilize secondary data or request synchronization.
