Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information management devices for work machines face challenges in efficiently managing and transmitting vehicle information and analysis information, particularly in controlling the provision of data based on the administrator's purpose, network characteristics, and user position when new functions or devices are added.
Innovation Solution
An information management device with an information collection unit, analysis unit, selection definition storage unit, and information selection unit that determines the transmission of vehicle and analysis information to general-purpose processing units based on predefined selection definitions, ensuring secure and purposeful data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new function units or devices are added to transmit and analyze vehicle information, then the functionality and versatility of the information management device is improved, but the complexity of managing information provision and the risk of unauthorized access increases
Solution Approach 1:
The patent segments information into different types (vehicle information, analysis information) and organizes it into separate storage units (first storage unit, second storage unit). This segmentation allows for targeted management and transmission of specific information types to different destinations, reducing the complexity of managing all information uniformly while maintaining versatility.
Solution Approach 2:
The patent introduces a server as an intermediary component that mediates between the information management device and external devices. The server receives information from the information management device and distributes it to appropriate external devices based on transmission definitions, thereby simplifying the information management device's role and reducing its management complexity while maintaining system versatility.
2Loss of information
If all vehicle information and analysis information is transmitted to external devices, then the completeness of information provision is improved, but the security and control over information access deteriorates
Solution Approach 1:
The patent applies local quality by creating transmission definitions that are specific to different information types and different external devices. Each transmission definition selectively specifies which information should be transmitted to which device, ensuring that each external device receives only the information it needs rather than all information, thereby maintaining security while providing complete relevant information.
Solution Approach 2:
The patent changes the parameter of information transmission by introducing transmission definitions that control transmission based on information type, destination, and other parameters. This allows dynamic control over what information is transmitted, ensuring completeness of necessary information while maintaining security through selective transmission rather than blanket transmission of all information.
3Measurement precision
If transmission definitions are configured for each external device and information type, then the precision of information provision control is improved, but the complexity of configuration and maintenance increases
Solution Approach 1:
The patent implements universality by designing transmission definitions with a standardized structure that can be applied across multiple external devices and information types. The transmission definition includes universal elements such as information type identification, destination identification, and transmission control parameters that can be consistently applied regardless of the specific device or information type, reducing configuration complexity while maintaining control precision.

AI summary
An information management device of a work machine includes an information collection unit that collects vehicle information of the work machine, an information analysis unit that analyzes the vehicle information to generate analysis information, a selection definition storage unit that stores a selection definition that defines transmission propriety information indicating whether it is allowed to transmit the vehicle information and the analysis information to a general-purpose processing function unit, and an information selection unit that selects, based on the selection definition, information to be transmitted to the general-purpose processing function unit.
