Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual marking is performed by workers based on original drawings, then flexibility and adaptability are maintained, but marking accuracy deteriorates due to dependence on worker proficiency

Engineering Contradiction:
Improvemarking accuracyVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The marking system performs self-positioning and self-correction by autonomously detecting its own location through sensor scanning and comparing it with reference map data, then automatically correcting positional deviations without requiring manual intervention or complex external positioning equipment

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system replaces manual mechanical marking operations with automated sensing and control mechanisms, using sensor arrays to detect spatial coordinates and electronic control systems to adjust marking positions, thereby eliminating dependence on worker skill while maintaining system simplicity

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

2Manufacturing precision

If machine/robot is used for marking work, then marking accuracy is improved, but the machine requires complex functions to autonomously determine its position

Engineering Contradiction:
Improvemarking accuracyVSAvoidposition determination complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The sensor unit serves multiple functions: it scans the surrounding environment to generate spatial data, detects the machine's current position by comparing scan data with reference maps, and provides positioning information for correction, thereby eliminating the need for separate positioning equipment

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system continuously scans the environment, compares detected positions with reference map data, identifies deviations, and automatically corrects positioning errors, creating a closed-loop feedback system that maintains accuracy without complex external intervention

Inventive Principle:
Principle #23Feedback
