Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack efficient and convenient methods for automating transactions and navigation services using paired portable devices and onboard computers, relying on manual authentication and limited integration with external services.
Innovation Solution
A system that electronically pairs portable devices with onboard vehicle computers, enabling wireless transactions and navigation route modifications by authenticating the pairing through shared authentication information, allowing for seamless interactions with external services and points of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual authentication is used for vehicle transactions and services, then security can be maintained, but convenience and automation are reduced
Solution Approach 1:
The system performs preliminary pairing between the portable device and on-board computer before transactions occur. This pairing establishes authentication credentials in advance, allowing automated transactions to proceed without manual authentication steps while maintaining security through pre-configured verification mechanisms.
Solution Approach 2:
The patent introduces an on-board computer as an intermediary device that mediates between the portable device and external services. This intermediary holds and manages authentication credentials, enabling automated transactions by acting as a trusted intermediary that verifies identities without requiring direct manual authentication between all parties.
2Reliability
If pairing authentication is implemented for external services, then transaction security is improved, but system complexity increases
Solution Approach 1:
The on-board computer serves multiple functions: it acts as a communication interface for the vehicle, stores authentication credentials, verifies portable devices, and interfaces with external services. This multi-functional design consolidates security operations into an existing vehicle component rather than requiring separate dedicated security hardware, thereby improving security without proportionally increasing system complexity.
3Adaptability or versatility
If wireless communication capabilities are added to vehicles, then service integration with external systems is enhanced, but vulnerability to unauthorized access increases
Solution Approach 1:
The system implements a feedback mechanism where the on-board computer continuously verifies the portable device's authentication credentials during wireless communication. This feedback loop ensures that only authenticated devices can access vehicle services, dynamically controlling access based on verification results and preventing unauthorized access while maintaining open wireless communication capabilities.

AI summary
Various examples are disclosed of how to leverage technology in a vehicle to provide various services in a convenient manner. For example, the pairing of the portable device with the on-board computer of the vehicle may be utilized as a level of authorization to provide certain services in a more automated and/or convenient way to the vehicle driver or other occupant of the vehicle, such as by authenticating wireless transactions with entities external to the vehicle using device pairing technology, and by modifying vehicle navigation routes to include suggested nearby points of interest that may be determined to be of particular value to a vehicle occupant.
