Vehicular Communication Apparatus Terminal-Linked Facility Data Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular communication systems lack protection for private information transmitted from portable communication terminals, as they do not prevent unauthorized access to facility information when a new portable terminal is connected.
Innovation Solution
A vehicular communication apparatus with an information acquisition device, storage, and display control that only displays facility information when the original portable communication terminal is reconnected, preventing display and access when a different terminal is connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If facility information is stored and displayed for any connected portable communication terminal, then ease of operation is improved, but information security deteriorates
Solution Approach 1:
The patent applies local quality by making the display function conditional on the specific portable communication terminal being the authorized one. The vehicular communication apparatus checks whether the connected terminal matches the stored terminal information, and only displays facility information when there is a match. This creates a localized security control where the same system behaves differently for authorized versus unauthorized terminals.
2Object-affected harmful factors
If facility information is protected by restricting access, then information security is improved, but ease of operation deteriorates
Solution Approach 1:
The system applies self-service by automatically checking whether the connected portable communication terminal is authorized to access facility information. The vehicular communication apparatus performs the verification autonomously by comparing the connected terminal's identification with the stored terminal information, and automatically controls the display accordingly without requiring manual intervention from the user.
3Adaptability or versatility
If facility information is made available to all connected terminals, then adaptability is improved, but information security deteriorates
Solution Approach 1:
The patent applies dynamics by making the system's response adaptive to the identity of the connected terminal. The display control dynamically adjusts based on whether the connected terminal matches the authorized terminal stored in the vehicular communication apparatus. When there is a match, facility information is displayed; when there is no match, it is not displayed. This dynamic behavior allows the system to be adaptable to different terminals while maintaining security.

AI summary
A vehicular communication apparatus communicably connected to a portable communication terminal, includes: an information acquisition device that acquires facility information about a facility from the portable communication terminal; an information storage device that controls a storage to store the facility information in association with the portable communication terminal; and an information display device that controls a display to display the facility information stored in the storage when the portable communication terminal providing the facility information is reconnected to the vehicular communication apparatus, and that controls the display not to display the facility information stored in the storage when a new portable communication terminal different from the portable communication terminal providing the facility information is connected to the vehicular communication apparatus.
