Navigation System Starting Point Derivation for Retail Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems struggle to activate the simulation mode in retail settings due to the inability to receive GPS signals, leading to a lack of user experience and irrational purchasing decisions, as customers are unable to manually input the starting point effectively.
Innovation Solution
A method where the navigation system automatically derives a starting point from the input destination using a starting point derivation rule, allowing the simulation mode to be initiated without user intervention, ensuring seamless operation and functionality demonstration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the starting point is automatically determined by evaluating current position using GPS signals, then the simulation mode can be easily activated, but GPS signals cannot penetrate the retail store structure causing the starting point to be indeterminable
Solution Approach 1:
The system stores multiple candidate starting points in advance within the road network database, associated with each destination. When GPS signals are unavailable, the system retrieves a suitable candidate starting point from the stored data rather than requiring real-time position determination, enabling simulation mode to function without GPS signals.
Solution Approach 2:
The system creates a simulated starting point based on stored candidate locations rather than using the actual current position. This copy of a starting point allows the simulation to proceed with realistic route calculation even though the true current position cannot be determined without GPS signals.
2Adaptability or versatility
If manual input of starting point is required for simulation mode, then the simulation can be realized without GPS signals, but customers do not input the starting point due to inexperience and the simulation mode is not activated
Solution Approach 1:
The system automatically selects and provides suitable starting points from stored candidates without requiring customer input. The navigation system serves itself by generating the necessary starting point information, eliminating the need for customers to manually input location data despite their inexperience.
Solution Approach 2:
The road network database serves multiple functions: it stores not only route information but also pre-associated candidate starting points for various destinations. This multi-functional use of the database enables the system to provide simulation mode functionality without requiring additional customer input or specialized retail-store adaptations.
3Ease of operation
If fixed starting points are defined for demonstration mode at the factory, then the simulation mode can be activated, but this results in undesirably long simulation routes or routes not covered by the actually existing map base
Solution Approach 1:
Instead of using fixed starting points defined at the factory, the system dynamically selects starting points from multiple candidates stored in the road network database. The selection can adapt to various destinations and conditions, ensuring that simulation routes are appropriate in length and covered by the actual map base rather than being static pre-defined routes.

AI summary
A method for operating a navigation system includes the following steps: a) inputting a destination; b) deriving a starting point from the destination being input by utilizing a starting point derivation rule; c) calculating a route from the derived starting point to the destination being input, and d) outputting the simulated route preview from the derived starting point to the destination being input. Preferably, the navigation system includes an input device for inputting operator commands and/or location information, particularly starting points and/or destinations, a road network database, a route calculating unit for calculating a planned route with consideration of the location information and the road network database, wherein the route leads from the starting point to the destination, a signal receiving unit for receiving position signals, particularly GPS signals, a position finding unit that determines the current position from the position signals, and at least one optical and/or acoustical output device for optically and/or acoustically outputting a simulated route preview in a simulation mode, wherein the simulated route preview simulates the route navigation from a starting point to a destination.
