Navigation System Simulation Mode Starting Point Derivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems face challenges in activating simulation mode in retail settings due to lack of GPS signals, requiring manual entry of the starting point, which is not intuitive for users, leading to missed opportunities for evaluating the system's functionality before purchase.
Innovation Solution
A method where the starting point for simulation mode is automatically derived from the entered destination using a starting point derivation rule, allowing the system to calculate and display a simulated route preview without user intervention, ensuring seamless activation of simulation mode even without GPS signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual entry of starting point is required for simulation mode, then the system can operate without GPS signals, but user experience deteriorates due to non-intuitive operation
Solution Approach 1:
The navigation system automatically determines the starting point for simulation mode by deriving it from the destination input, eliminating the need for manual starting point entry. The system serves itself by using the destination information already provided by the user to automatically establish both starting and ending points for route calculation.
Solution Approach 2:
The system performs preliminary determination of the starting point before route calculation by deriving it from the destination. This preliminary action ensures that when simulation mode is activated, both starting and destination points are already established, allowing immediate route calculation without requiring additional user input.
2Productivity
If current position is used as starting point, then normal navigation operates smoothly, but simulation mode cannot be activated in retail stores without GPS signals
Solution Approach 1:
The system changes the parameter for determining the starting point based on availability of GPS signals. When GPS signals are unavailable (as in retail stores), the system switches to deriving the starting point from the destination parameter. This parameter change allows the system to adapt to different operational contexts while maintaining simulation mode functionality.
Solution Approach 2:
The navigation system achieves universality by handling multiple scenarios: it can use current position when GPS signals are available, and derive starting point from destination when GPS signals are unavailable. This multi-functionality ensures simulation mode can be activated in both normal navigation contexts and retail demonstration environments.
3Ease of operation
If factory definition starting points are used for demonstration mode, then simulation can be activated, but routes become excessively long or exceed map base coverage
Solution Approach 1:
The system performs preliminary derivation of the starting point from the destination before route calculation. This preliminary action ensures that the starting point is logically related to the destination (typically in the same city or region), which prevents the system from selecting arbitrary factory definition starting points that would create excessively long routes.
Solution Approach 2:
The system applies local quality by deriving the starting point based on the destination's location characteristics. The starting point is determined to be in the same city or region as the destination, ensuring that the simulation route is locally relevant and manageable in length, rather than using generic factory definition points anywhere in the world.

AI summary
The method involves determining input of target points. A derivative of a starting point is determined from the entered target point using a starting point derivation rule. A route of the derived starting point is computed to the entered target point. Output of the simulated route preview from the derived starting point to the entered target point is obtained.
