Solution Overview
Problem
Existing in-vehicle apparatuses face resource insufficiency issues due to the need for driver information for mobile communication terminals, which can lead to inadequate utilization of terminal devices.
Innovation Solution
An in-vehicle apparatus equipped with a storage unit to store terminal device information and an in-vehicle device management unit to transmit device use requests to the terminal, allowing efficient utilization of terminal devices without requiring pre-existing driver information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If driver information is stored in the in-vehicle apparatus for terminal device use, then the terminal device can be used effectively, but the resource of the in-vehicle apparatus becomes insufficient
Solution Approach 1:
The patent extracts the driver information storage function from the in-vehicle apparatus and relocates it to the terminal device itself. The terminal device stores its own driver information locally, eliminating the need for the in-vehicle apparatus to maintain this resource inventory. This extraction resolves the contradiction by preserving terminal device usability while freeing up resources in the in-vehicle apparatus.
Solution Approach 2:
The terminal device performs self-service by storing and managing its own driver information. Instead of relying on the in-vehicle apparatus to provide and manage driver information, the terminal device independently handles this function. This self-service approach allows the terminal device to be effectively used without consuming additional resources from the in-vehicle apparatus.
2Ease of operation
If the in-vehicle apparatus stores terminal device information, then terminal device use can be managed, but the processing capability is reduced due to resource insufficiency
Solution Approach 1:
The patent extracts the terminal device information storage and management functions from the in-vehicle apparatus to the terminal device. By removing this information handling responsibility from the in-vehicle apparatus, the system reduces the processing burden on the in-vehicle apparatus, thereby preserving its processing capability while maintaining ease of terminal device management.
Solution Approach 2:
The terminal device acts as an intermediary that stores and manages its own driver information. This intermediary role eliminates the need for the in-vehicle apparatus to maintain detailed information about terminal devices, reducing the processing requirements on the in-vehicle apparatus while still enabling effective terminal device management.
3Adaptability or versatility
If driver information is pre-stored in the in-vehicle apparatus, then terminal device use is enabled, but the device complexity increases due to insufficient resources
Solution Approach 1:
The patent extracts the driver information storage function from the in-vehicle apparatus and places it in the terminal device. This extraction reduces the information storage requirements of the in-vehicle apparatus, thereby reducing device complexity while maintaining terminal device compatibility through the terminal's local information storage capability.
Solution Approach 2:
The terminal device performs self-service by storing and managing its own driver information. This self-service approach eliminates the need for the in-vehicle apparatus to maintain complex information storage structures, reducing overall device complexity while preserving adaptability and compatibility with various terminal devices.
Data Source
AI summary
The in-vehicle apparatus includes a storage unit that stores terminal device information for using a terminal device included in a mobile communication terminal communicably connected to the in-vehicle apparatus, and an in-vehicle device manager that transmits, to the mobile communication terminal, a terminal device use request that is a request to use the terminal device based on the terminal device information stored in the storage unit. In the in-vehicle apparatus, when a terminal device use request is transmitted from the in-vehicle device manager to the mobile communication terminal, data is acquired by the terminal device, and the data is input to the in-vehicle apparatus from the mobile communication terminal.
