Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation devices face limitations in accessing network resources like the Internet due to reliance on GPS and the need for expensive and non-ubiquitous packet data service connections, which restricts their functionality and feature expansion.
Innovation Solution
A Bluetooth-enabled navigation device discovers and stores profile information of nearby mobile phones, establishing a Bluetooth connection to use their wireless telecommunications network for Internet Protocol network access, allowing data exchange through modulation of digital data into audio frequency tones for transmission over voice channels, enabling real-time location-based information and feature expansion without requiring specialized transceivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If navigation devices use GPS and speakers/displays to output information, then location-based navigation function is achieved, but network access capability is limited due to lack of expensive satellite transceivers and ubiquitous packet data service connections
Solution Approach 1:
The patent introduces a mobile phone as an intermediary device that provides network access capability to the navigation device. The mobile phone acts as a mediator between the navigation device and the network infrastructure, allowing the navigation device to access remote networks without requiring its own expensive satellite transceiver or packet data service connection. The system discovers available mobile phones, establishes Bluetooth connections, and uses the mobile phone's network capabilities to enable Internet Protocol network access for the navigation device.
2Adaptability or versatility
If navigation devices require expensive satellite transceivers and packet data service connections for network access, then remote network access is achieved, but cost and ubiquity are compromised
Solution Approach 1:
The patent applies universality by enabling the navigation device to utilize the mobile phone's existing wireless telecommunications network capabilities for Internet Protocol network access. Instead of requiring the navigation device to have its own specialized transceiver and packet data service connection, the system allows any Bluetooth-enabled mobile phone to serve as a network access point. This multi-functional approach lets the mobile phone's wireless network interface serve dual purposes: its original function and providing network access to the navigation device, thereby improving ubiquity without sacrificing network access capability.
3Adaptability or versatility
If navigation devices establish Bluetooth connections with mobile phones for network access, then feature expansion and real-time information access are achieved, but dependency on mobile phone availability is introduced
Solution Approach 1:
The patent implements preliminary action through the discovery and storage of mobile phone profile information in a database before network access is actually needed. The system proactively scans for available mobile phones, discovers their Bluetooth profile capabilities, and stores this information in advance. When network access is required, the navigation device can quickly retrieve the stored profile information and establish a connection without delay. This preliminary preparation mitigates the reliability issue by ensuring that mobile phone availability is assessed and connection parameters are ready before they are critically needed.

AI summary
In one example, a Bluetooth enabled mobile device discovers the Bluetooth profile capability of a plurality of mobile phones and stores the profile information in a database. Thereafter, when access to a remote network such as an Internet Protocol (IP) network is necessitated by an event, the Bluetooth enabled mobile device can establish a Bluetooth connection with an available mobile phone according to a comparison of the event to the stored profile information for that mobile phone. The Bluetooth enabled mobile device can then establish a transport layer connection that extends over the established Bluetooth connection and a wireless telecommunications network associated with the available phone and exchange data with a remote network using the established transport layer connection.
