Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation devices lack the ability to provide both detailed and global route information simultaneously, making it difficult for drivers to anticipate maneuvers and navigate safely, especially in unforeseen events, and are often ergonomically poor and memory-intensive.
Innovation Solution
A navigation method and device that allows users to choose between different levels of detail, offering a navigation mode for visual cartographic representation, a cartographic mode for detailed route elements, and an instruction mode with schematic instructions, enabling both global and detailed understanding of a route with quick mode switching and flexible layout management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple types of navigation information are provided simultaneously, then the driver can have better knowledge of both immediate environment and future stages, but the screen size becomes insufficient to display all information
Solution Approach 1:
The navigation information is segmented into three distinct guidance modes (navigation mode, cartographic mode, written instructions mode), each displaying a specific type of information. The system divides the comprehensive route data into manageable segments that can be displayed on the limited screen area, allowing the driver to access different levels of detail as needed without overwhelming the display.
Solution Approach 2:
The system dynamically switches between different guidance modes based on driver needs and route context. The display content is not static but can be adjusted in real-time, allowing the navigation device to adapt the information presentation to the current situation, thereby maximizing the utility of the limited screen area while maintaining information completeness.
2Reliability
If detailed route information is provided, then the driver can anticipate maneuvers better, but the device complexity and memory capacity requirements increase
Solution Approach 1:
The system extracts only the essential route information needed for safe navigation and presents it in a simplified format. By focusing on critical maneuvers and key route elements rather than displaying all possible data, the device reduces memory requirements and processing complexity while maintaining navigation safety through targeted information delivery.
Solution Approach 2:
The navigation system applies different levels of detail to different parts of the route information. Critical upcoming maneuvers receive more detailed presentation, while less critical sections are summarized. This local differentiation of information quality allows comprehensive navigation safety without uniformly high memory usage across all route data.
3Adaptability or versatility
If multiple guidance functions are integrated, then the navigation device offers more versatility, but the ergonomics and ease of operation deteriorate
Solution Approach 1:
The navigation device integrates multiple guidance functions (visual cartographic representation, detailed route elements, written instructions) into a single unified system. This multi-functionality allows the device to adapt to different driver preferences and situations while maintaining a consistent user interface, thereby achieving versatility without sacrificing ease of operation.
Solution Approach 2:
The system periodically offers different guidance modes to the driver, allowing switching between navigation mode, cartographic mode, and written instructions mode. This periodic availability of different guidance types provides versatility while maintaining operational simplicity through consistent access methods and uniform interface patterns across modes.

AI summary
The invention relates to a navigation method which comprises the following steps: receiving computerised data relating to a route (101); obtaining computerised data relating to the manoeuvres to be performed along the route (102); obtaining computerised data relating to the corresponding directions (103); obtaining computerised data relating to the position of the guided object; correlating the data relating to the position of the guided object (400) with the data relating to the route; processing the computerised route data according to a plurality of guide modes, i.e. a navigation mode (200), a mapping mode (300) and a direction mode (400); guiding, while referring to one of the preprocessed modes, and placing the other preprocessed guide modes on stand-by; and allowing the substantially instant activation of the modes placed on stand-by. The invention also relates to a corresponding navigation device.
