Solution Overview
Problem
GPS navigation devices often fail to provide reliable cellular communication in areas with limited or no coverage, as they require remote server connections to access cellular provider information, which may not be available during travel through unfamiliar or remote regions.
Innovation Solution
A GPS navigation device with integrated cellular detection and route planning capabilities, featuring a portable GPS and cellular receiver, memory, processor, and display unit that processes geographic and cellular provider information to generate route instructions ensuring continuous cellular coverage without external server connection, and displays real-time cellular provider information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS navigation devices require remote server connections to access cellular provider information, then route planning can be performed with accurate cellular coverage data, but the device cannot provide reliable cellular communication information in remote areas where server connection is unavailable
Solution Approach 1:
The device pre-loads cellular provider coverage information and geographic data into its local memory before travel. This preliminary action enables the device to provide route planning with cellular coverage information without requiring real-time server connections, resolving the contradiction between reliability in remote areas and dependence on remote servers.
Solution Approach 2:
The GPS navigation device integrates multiple functions including GPS reception, cellular signal detection, route planning, and cellular provider information display into a single device. This multi-functionality eliminates the need for separate server connections by combining navigation and cellular detection capabilities, improving reliability while managing device complexity.
2Adaptability or versatility
If GPS navigation devices integrate cellular detection and route planning capabilities, then users can receive driving instructions with maintained cellular coverage, but the device complexity increases
Solution Approach 1:
The patent merges GPS reception, cellular signal detection, route planning, and provider information display into an integrated system. By combining these previously separate functions into one unified device, the patent achieves cellular route planning capability while managing complexity through integration rather than multiplication of separate components.
Solution Approach 2:
The navigation device is designed as a multi-functional universal device that performs GPS navigation, cellular signal detection, route planning based on cellular coverage, and real-time provider information display. This universality provides adaptability for cellular route planning while consolidating functions to control overall device complexity.
3Loss of information
If GPS navigation devices display real-time cellular provider information, then users can maintain awareness of cellular coverage status, but the device requires additional processing and detection capabilities
Solution Approach 1:
The device continuously detects cellular signal strength and provider information through its cellular antenna and provides real-time feedback to the user via display. This feedback mechanism ensures users maintain awareness of cellular coverage status throughout their journey, with the processing integrated into the existing navigation system to manage complexity.
Solution Approach 2:
The cellular antenna and detection capabilities are integrated into the multi-functional navigation device, serving both route planning purposes and real-time information display. This universal design allows the same hardware components to support multiple functions, reducing overall device complexity while providing comprehensive cellular information.
Data Source
AI summary
A navigation device for navigating from one location to another includes a GPS receiver for receiving GPS signals, a cellular receiver for receiving cellular signals, a memory, a processor, a display unit and a connection unit for receiving navigation data. The navigation data includes geographic and cellular provider information pertaining to the locations where cellular coverage is available by a particular provider. This information is processed by the processor to display route instructions to a user in which cellular coverage will be maintained.
