GPS Phone Navigation Pairing for Vehicle Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems and GPS-enabled wireless phones lack communication and coordination, making it difficult for users to locate their vehicle in unfamiliar environments, such as large parking lots, and do not seamlessly transfer navigation information between devices.
Innovation Solution
A secure pairing mechanism between GPS-enabled wireless phones and navigation systems allows for the exchange of GPS information, including coordinates and routes, via wired or wireless links, enabling the phone to direct users back to their vehicle even when separated, using devices like keychains or watches for navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a navigation system is mounted within a vehicle and a GPS-enabled wireless phone is used separately, then each device can independently provide navigation or location services, but there is no communication between the devices making it difficult to locate the vehicle when separated
Solution Approach 1:
The patent combines the navigation system and GPS-enabled wireless phone into an integrated system where the phone can detect separation from the vehicle and automatically provide directions back to it. The system merges functionality by allowing the phone to serve both as a communication device and a vehicle-location finder, eliminating the need for separate systems while maintaining reliability.
Solution Approach 2:
The GPS-enabled wireless phone is designed to perform multiple functions: normal wireless communications, navigation assistance, and vehicle location tracking. When separated from the vehicle, the phone universally serves as both a communication device and a tool to locate and navigate back to the vehicle, reducing the need for dedicated specialized devices.
2Adaptability or versatility
If navigation information is exchanged between GPS-enabled devices and vehicle-mounted systems, then users can seamlessly transfer routes and coordinates between devices, but communication protocols and data formats must be standardized across different systems
Solution Approach 1:
The system establishes universal communication capabilities between GPS-enabled devices and vehicle-mounted systems by implementing standardized data exchange protocols. This allows different device types (phones, tablets, navigation systems) to interchangeably share navigation information such as routes, coordinates, and location data without requiring system-specific adaptations.
Solution Approach 2:
The patent introduces a standardized communication interface that acts as an intermediary between different GPS-enabled devices and vehicle systems. This intermediary layer handles data format conversion and protocol standardization, allowing seamless information exchange while abstracting away the complexity of direct device-to-device communication protocols.
3Reliability
If a secure pairing mechanism is implemented between GPS-enabled wireless phones and navigation systems, then GPS information including coordinates and routes can be exchanged, but the pairing and authentication process adds initial setup complexity
Solution Approach 1:
The system performs secure pairing and authentication in advance before navigation operations begin. During the initial setup phase, the GPS-enabled device and vehicle system establish secure connections and exchange encryption keys beforehand, so that subsequent data exchanges occur automatically without requiring repeated authentication, thus maintaining security while simplifying ongoing operations.
Solution Approach 2:
The secure pairing mechanism is designed to be self-service oriented, where the system automatically manages authentication credentials, encryption keys, and connection establishment without requiring manual intervention for each data exchange. The initial setup guides users through one-time pairing, after which the system autonomously maintains secure communications.
