Solution Overview
Problem
Existing navigation devices fail to predictively provide the fastest route to a destination due to unpredictable factors like accidents, changing road conditions, and varying traffic patterns, requiring users to manually manage their navigation devices to plan routes and arrive at desired times.
Innovation Solution
A navigation device method and system that allows users to input a travel destination and desired arrival time, calculating and displaying the relationship between permitted and calculated speeds, as well as providing real-time updates on arrival leeway, using GPS data and integrated input and display devices with processors to determine routes and output speed and time-related information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If navigation devices provide multiple alternative routes, then users have more route options, but users cannot predict which route will be fastest due to unpredictable factors
Solution Approach 1:
The navigation device performs preliminary calculations by determining a travel route and calculating the speed required to reach the destination by a desired arrival time before the user departs. This allows users to plan ahead and understand what speed is needed, eliminating the need for separate manual planning during travel.
Solution Approach 2:
The system continuously outputs information about the relationship between permitted speed and calculated speed during travel, providing real-time feedback to users. This allows users to adjust their driving to maintain the calculated speed needed for on-time arrival, automatically adapting to changing conditions.
2Reliability
If navigation devices inform users about speed limits, then users receive speed warnings, but users lack information about the speed needed to arrive at the desired time
Solution Approach 1:
The system merges speed limit information with arrival time calculations by determining both the permitted speed and the calculated speed needed to reach the destination by the desired arrival time. This combination provides users with comprehensive speed information that incorporates both safety constraints and time management requirements.
Solution Approach 2:
The navigation device performs multiple functions: it provides speed limit warnings, calculates required speeds for on-time arrival, and outputs the relationship between these speeds. This multi-functional approach eliminates the need for separate devices or manual calculations for time management.
3Ease of operation
If users manually manage navigation devices to plan routes and arrival times, then users have control over their journey, but users experience increased complexity and time investment
Solution Approach 1:
The navigation device performs automatic calculations of the speed required to reach the destination by the desired arrival time based on the determined route. The system serves itself by computing this information without requiring separate manual planning operations from the user, reducing operational complexity while maintaining control.
