Solution Overview
Problem
Existing navigation devices face challenges in efficiently selecting the best traffic message channel based on signal strength and user location, leading to suboptimal traffic information delivery.
Innovation Solution
A navigation device with a receiver to determine signal strength, a memory to store this information, and a processor to compile a traffic message channel resource, allowing selection of the most suitable channel based on location and user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the navigation device scans traffic message channels to find the strongest signal, then traffic information can be received, but the device cannot consistently select the optimal channel along a route
Solution Approach 1:
The navigation device performs preliminary scanning and signal strength measurement of traffic message channels before the user's journey begins. This advance preparation creates a pre-computed resource database that enables rapid channel selection during travel without requiring real-time scanning, thus ensuring reliable traffic information delivery while simplifying the operational complexity during actual use.
Solution Approach 2:
The system dynamically adapts channel selection based on the user's current location and movement along the route. By correlating stored signal strength information with real-time position data, the device automatically transitions between different optimal channels as the user moves through areas with varying signal characteristics, maintaining reliable traffic information reception throughout the journey.
2Measurement precision
If the navigation device scans and evaluates multiple traffic message channels in real-time, then it can select the strongest signal, but this consumes excessive time and resources
Solution Approach 1:
Signal strength measurements and channel evaluations are performed in advance during an initialization phase or during periods when the device is stationary. The results are stored in a resource database that contains pre-computed information about optimal channel selection for different geographic locations. During actual travel, the device simply queries this pre-computed data based on current position, eliminating the need for time-consuming real-time scanning and evaluation.
3Adaptability or versatility
If the navigation device stores signal strength information for multiple channels, then it can make informed selections, but memory requirements increase
Solution Approach 1:
The system stores signal strength information in a structured resource database organized by geographic location and channel identifier. Rather than storing all possible channel data uniformly, the database contains localized information relevant to specific geographic areas, allowing the device to adapt its selection capability to the user's current location while optimizing memory usage by only storing necessary local data.
