VSEngineering Contradiction Analysis

1Productivity

If manual map creation methods are used (user operates drawing device to traverse boundary and manually draw obstacle distribution), then the map can be created for autonomous robot operation, but the process is labor-intensive and inefficient

Engineering Contradiction:
Improvemap creation efficiencyVSAvoidtime required for manual map creation
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The autonomous robot performs boundary detection and map creation autonomously using its onboard sensors and positioning systems. The robot automatically traverses the boundary, detects features, and generates the operation area map without human intervention, transforming a manual task into an automated self-service process

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical drawing operations with automated sensor-based detection systems. The robot uses positioning devices, detection devices, and processing units to automatically capture boundary coordinates and generate digital maps, substituting mechanical manual labor with electronic automation

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If commercial map software is used to manually delineate operation area and obstacle distribution, then labor intensity is reduced and efficiency is improved, but the precision of the created map is insufficient

Engineering Contradiction:
Improvemap creation efficiencyVSAvoidmap precision
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The map creation process is divided into distinct functional modules: positioning module for accurate location determination, detection module for boundary and feature identification, and processing module for map generation. This segmentation allows each module to be optimized independently, achieving both high efficiency and high precision

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system incorporates feedback mechanisms where the robot continuously monitors its position using positioning devices, compares detected boundaries with the generated map, and refines the map data accordingly. This iterative feedback process ensures high precision while maintaining automated efficiency

Inventive Principle:
Principle #23Feedback
