Solution Overview

Problem

Existing route map generation methods are inefficient in terms of memory usage, ergonomics, and clarity, often requiring high memory capacity and bandwidth, which limits device compatibility and increases technical costs, and they lack precise visual details for end-effector maneuvers, making them impractical for real-time navigation.

Innovation Solution

A method and system that generate route maps with reduced memory usage by using schematic representations with standardized angular positions for entry and exit points, allowing for optimized ergonomics and readability, and integrating maneuver detection to provide clear instructions, while reducing unnecessary data and adapting layout characteristics based on available surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If complete cartographic format route maps are used, then route information completeness is improved, but memory capacity requirements increase

Engineering Contradiction:
Improveroute information completenessVSAvoidmemory capacity
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent divides the route into multiple sections, each represented by a simplified schematic diagram showing only essential geometric features (entry point, exit point, maneuver points). This segmentation allows the route information to be complete while using minimal memory, as each section is represented by a few key coordinates rather than full cartographic details.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts only the essential elements needed for route following (entry points, exit points, maneuver points) from the complete cartographic representation. By removing unnecessary cartographic details while preserving the critical geometric information, the system achieves complete route information with reduced memory requirements.

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of information

If multiple pages for the same route sector are provided, then route information detail is improved, but ease of operation during navigation deteriorates

Engineering Contradiction:
Improveroute information detailVSAvoidhandling of route maps
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent merges multiple pages of route information into a single continuous schematic representation. The route is displayed as a sequence of connected sections on one page, eliminating the need to handle multiple separate pages while maintaining complete route information through the continuous visual representation.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of information

If detailed written instructions are provided without precise relation to the map, then instruction completeness is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveinstruction completenessVSAvoidreading and understanding instructions
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent merges the written instructions with the visual schematic representation by placing them in direct spatial correspondence. Each instruction is positioned next to its corresponding section of the route diagram, creating an integrated display that combines complete instructional information with easy visual understanding.

Inventive Principle:
Principle #5Merging (Combining)

4Measurement precision

If precise visual details on end-effector maneuvers are provided, then maneuver accuracy is improved, but memory capacity requirements increase

Engineering Contradiction:
Improvemaneuver visual detail precisionVSAvoidmemory capacity
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent applies local quality by providing enhanced visual detail only at critical maneuver points (entry points, exit points, turns) while using simplified representations for straight sections. This selective detail provision ensures accurate maneuver information where needed while minimizing overall memory requirements.

Inventive Principle:
Principle #3Local quality

5Loss of information

If complete cartographic format route maps are transmitted, then route information completeness is improved, but network bandwidth consumption increases

Engineering Contradiction:
Improveroute information completenessVSAvoidnetwork bandwidth consumption
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent extracts only the essential geometric data (coordinates of entry points, exit points, and maneuver points) from complete cartographic representations for transmission. This extraction maintains route information completeness while dramatically reducing the data volume and network bandwidth consumption.

Inventive Principle:
Principle #2Taking out (Extraction)

6Loss of information

If complete cartographic format route maps are processed, then route information completeness is improved, but processing time increases

Engineering Contradiction:
Improveroute information completenessVSAvoidprocessing time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent segments the route into discrete sections with simplified geometric representations, allowing for rapid processing of each section independently. This segmentation reduces the overall processing time while maintaining complete route information through the cumulative representation of all sections.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a method for automatically generating route maps, comprising the following steps: receiving a route to be mapped (101); and formatting the data of the route in order to create an arrangement on a substrate, comprising the following steps: cutting the route (103) to be mapped into a plurality of sections; each section comprising at least one entrance point and one exit point; for each section, formatting a corresponding schematic representation of the part of the route in such a way that it is isolated from the corresponding geographic map (104); and formatting the sections in such a way that the entrance point and/or the exit point of each section is essentially in the same sector in relation to the substrate on which the sections are arranged (105). The invention also relates to a corresponding system for generating route maps.
