Hierarchical Route Display for Navigation Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems face challenges in presenting travel routes in a compact and understandable form, particularly in remote areas where street names alone are insufficient for user orientation, and the inclusion of additional information like political areas reduces clarity.
Innovation Solution
A display device that separates relevant from less relevant information by measuring attribute relevance based on user-centric criteria such as travel time and distance, using a hierarchical representation to prioritize location-related attributes over route-related ones, and summarizing attributes within hierarchy levels to maintain clarity on small screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If additional area names and political areas are included in the route information list, then comprehensibility is improved, but clarity is reduced due to increased information density
Solution Approach 1:
The route information is segmented into different hierarchy levels (first hierarchy level for area names, second hierarchy level for route section names). This segmentation allows the system to present comprehensive information while maintaining clarity by organizing it in a structured, hierarchical manner where only relevant information at each level is displayed simultaneously.
Solution Approach 2:
The patent introduces a hierarchical dimension to the display structure. Instead of presenting all information linearly in a single list, the information is organized across multiple hierarchy levels, with area names at the first level and route section names at the second level. This dimensional organization resolves the contradiction by allowing comprehensive information to be presented without overwhelming the display.
2Quantity of substance
If the route description is summarized in a text list format, then information is condensed, but the description becomes hardly practical for user orientation
Solution Approach 1:
The route information is divided into meaningful segments (area names and route section names) organized in hierarchy levels. This segmentation transforms a dense text list into a structured format that maintains both information density and practical usability by grouping related information together in a logical hierarchy.
Solution Approach 2:
Different parts of the route information are treated with different display qualities based on their relevance. Area names that provide orientation context are displayed at the first hierarchy level, while specific route section names are displayed at the second hierarchy level. This local quality differentiation enhances practicality by emphasizing orientation-critical information.
3Device complexity
If only street names and numbers are used as designations, then the display is compact, but users find it difficult to orientate themselves in remote areas
Solution Approach 1:
The display is segmented into hierarchy levels where the first level shows area names for orientation and the second level shows route section names for navigation. This segmentation allows the system to maintain display compactness while providing comprehensive orientation information by strategically placing different types of information at appropriate hierarchy levels.
Solution Approach 2:
The patent adds a hierarchical dimension to the display structure, organizing information across multiple levels rather than using a single flat list. This dimensional approach allows area names (for orientation) and route section names (for navigation) to coexist in a compact format by distributing them across different hierarchy levels.

AI summary
The present invention provides a display apparatus for displaying a travel route, wherein the travel route has a chain of route elements and each route element has a measurement value and a set of attributes. The display apparatus comprises a partial-chain detector, a calculation unit, a sorter and a display unit. The partial-chain detector detects for each attribute of at least one route element in each case a contiguous partial chain, which includes the route element, of a maximum length of route elements which have an identical attribute. The calculation unit calculates for each partial chain in each case one total measurement value from the measurement values of the route elements of the partial chain. The sorter sorts for the at least one route element the set of attributes according to a size relation of the total measurement values of the partial chains of attributes into a series of hierarchy planes, and the display unit shows the attributes of the at least one route element in hierarchical representation in accordance with the hierarchy planes.
