Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for determining the usability of application programs on in-vehicle devices do not adequately consider peripheral devices attached to the vehicle, leading to inappropriate installability assessments.
Innovation Solution
A mobility service providing system that includes a server, an in-vehicle device, a requirement storage unit, and components to obtain and abstract basic and additional vehicle information, enabling determination of application program usability by comparing hardware requirements with the abstracted information, encompassing both vehicle and peripheral device functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional techniques compare only basic vehicle information with hardware requirements, then the determination process is simple, but the usability assessment is inaccurate because peripheral devices are not considered
Solution Approach 1:
The patent segments device information into two distinct categories: basic information (vehicle-mounted devices) and additional information (peripheral devices). This segmentation allows the system to comprehensively collect all relevant device information while maintaining organized processing. The segmentation enables accurate usability assessment by ensuring both basic and additional devices are considered, resolving the contradiction between assessment accuracy and processing complexity.
Solution Approach 2:
The patent introduces an abstractor as an intermediary component that converts diverse device information from multiple sources into standardized abstracted information. This intermediary process simplifies the comparison between device capabilities and application requirements by creating a unified information format. The abstractor mediates between the complexity of collecting comprehensive device information and the simplicity needed for accurate usability determination.
2Reliability
If the system collects and processes comprehensive device information including peripheral devices, then usability determination accuracy improves, but the information processing time and complexity increase
Solution Approach 1:
The patent performs preliminary actions by collecting and abstracting device information in advance, storing it in a structured format before usability determination is needed. The in-vehicle device pre-collects basic information and pre-obtains additional information about peripheral devices, converting them into abstracted information that can be quickly compared with application requirements. This preliminary processing reduces the time required for actual usability determination while maintaining comprehensive and reliable assessment.
Solution Approach 2:
The patent changes the parameter format of device information by converting detailed device specifications into standardized abstracted information with defined parameters. This parameter transformation enables efficient comparison between device capabilities and application requirements. By standardizing information parameters in advance, the system achieves reliable usability determination without excessive processing time during actual installation decisions.
3Measurement precision
If the system uses detailed device information for usability determination, then the installability assessment becomes accurate, but the system complexity and processing requirements increase
Solution Approach 1:
The abstractor serves as an intermediary that transforms detailed and diverse device information into standardized abstracted information with unified parameters. This intermediary process maintains the precision needed for accurate installability assessment by preserving essential device capabilities while simplifying the information structure. The abstractor enables the system to handle comprehensive device information without proportionally increasing processing complexity.
Solution Approach 2:
The patent creates a universal abstracted information format that can represent various device types (vehicle-mounted devices and peripheral devices) with a common structure. This universal format enables the same processing logic to be applied regardless of the specific device type or information source. The multi-functional abstracted information structure allows the system to accurately assess installability for different applications while maintaining consistent and manageable processing complexity.

AI summary
A mobility service providing system includes an application database storing a hardware requirement required for executing an application program. A basic information obtainer obtains basic information that is hardware information regarding functions of a vehicle. An additional information obtainer obtains hardware information regarding a peripheral device group detachably attached to the vehicle. An information abstractor coverts obtained hardware information into information in a common format. An application provider compares hardware requirements associated with the application program with abstracted hardware information regarding the in-vehicle device to which the application program is downloaded, and determines usability of the application program in the in-vehicle device.
