Navigation Device Editable Image Database Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation devices lack the ability to be individually customized in terms of physical appearance, limiting user preferences and adaptability.
Innovation Solution
Incorporation of an editable image database that allows users to manage and store image data files for customizing the device's appearance, including assigning images to addresses and display functions, with options for storage on removable media and data linking for easy loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the navigation device uses a fixed physical appearance design, then the manufacturing and programming are simplified, but the user cannot customize the appearance according to individual preferences
Solution Approach 1:
The navigation device pre-provides a set of standard image files covering common customization needs (vehicle types, colors, icons). This preliminary preparation allows users to quickly customize appearance without complex manual image management, resolving the contradiction between customization capability and system complexity
Solution Approach 2:
The system enables parameter-based customization by allowing users to modify image parameters such as vehicle type, color, and icon selection through software configuration rather than physical changes. This achieves appearance adaptability while maintaining consistent hardware design, avoiding the complexity of multiple physical configurations
2Adaptability or versatility
If the navigation device provides extensive customization options, then user satisfaction increases, but the storage requirements and system complexity increase
Solution Approach 1:
The image database is designed to serve multiple functions: displaying vehicle icons, route markers, point-of-interest symbols, and interface elements. By making the image database universal and multi-functional, the system provides extensive customization options without proportionally increasing storage requirements, as the same image resources serve multiple purposes throughout the interface
Solution Approach 2:
The system uses scalable vector graphics and parameter-based image generation that allows a single image definition to be copied and reused in multiple contexts with different parameters (colors, sizes, positions). This copying approach enables extensive customization appearances while minimizing actual storage requirements, as the same base images are reused rather than storing separate files for each customization scenario

AI summary
A navigation device (1) including an input device for inputting operator commands and/or location data, particularly starting points and/or destinations, a road network database, a route calculating unit for calculating a planned route with consideration of the location data 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 determining unit that determines the current position based on the position signals, and at least one optical display device, has an editable image database, in which image data files (7) provided for being displayed on the display device can be managed in a user-defined fashion and method of operation.
